Job description
Building, shipping, and supporting AI\-powered tools and automations for 923 AI Automation clients. The role sits at the intersection of product thinking and AI engineering — closer to “product manager who builds confidently with modern AI development tools” than “AI research engineer.” You'll work with tools like Claude Code, the Anthropic API, and AI\-augmented low\-code platforms to deliver real systems to real clients, end\-to\-end.
You'll probably enjoy this role if you:* Like framing complex, ambiguous problems and working through them to clear solutions
- Enjoy ideating, building, and seeing things ship — then explaining clearly how and why they work
- Prefer direct interaction with a mentor over distant management
- Want autonomy and trust, not oversight for its own sake
- Want to understand why you're building something, not just what to build
- Are energised by seeing the whole picture — how a project connects to a client's business, a team's operations, and an emerging practice
You'll probably find this role frustrating if you:* Prefer to work deep in code with minimal client or stakeholder contact — the role sits in the middle of client delivery, not behind it
- Are looking for a role with highly structured processes, detailed specifications, and predictable work — this department is actively shaping its own way of working, and the person in this seat will be part of that shaping
Requirements
1\. Strategy \& Growth* Pattern Contribution — Surfacing new approaches, tools, and workflows discovered during client delivery, and contributing them to the department's knowledge base and operating models. Ideas are validated on real client work before they become standard.
- Continuous R\&D — Spending dedicated, reported hours testing new AI tools, models, and frameworks relevant to active or upcoming client work. Findings are shared with the Practice Lead and the wider department.
- Practice Building — Helping shape the way the department works as it scales — contributing to project templates, runbooks, evaluation approaches, and reusable components seeded from real delivered work.
2\. Solutions Engineering \& Client Delivery
This is the centre of gravity of the role. You'll be working alongside the Practice Lead and Account Manager on scoping, shaping, and solutioning new client engagements, then owning the delivery against those shaped briefs.
- Discovery \& Shaping Support — Joining discovery calls and shaping sessions with the Practice Lead to translate vague business problems into viable AI\-driven solutions. Initially, you'll join these calls to learn the pattern; over time, you'll take more of them directly as direction and confidence grow.
- Technical Feasibility — Evaluating client data, systems, and APIs to determine what's genuinely achievable within a proposed time budget. Flagging risks, rabbit holes, and integration blockers early, before commitments are made to the client.
- Demo Build\-Out — Building working demos for prospective clients that demonstrate the proposed solution against their real problem, ready to be presented on proposal calls.
- Proposal \& Scope Input — Contributing technical detail to proposals and statements of work — architecture approach, milestones, success criteria — which the Practice Lead translates into client\-facing documents.
- Client Onboarding \& Education — Helping client teams understand and confidently use the systems we deliver. This includes walkthroughs, training sessions where relevant, and clear handover documentation.
3\. Technical Execution
You'll own the technical delivery of client projects end\-to\-end, inside the department's established approach.
- Project Setup \& Architecture — Standing up new client projects — repository, environments, tooling, third\-party accounts — following the department's conventions. Designing the architecture of individual projects in line with 923's engineering and deployment standards.
- System \& Process Design — Designing the end\-to\-end system: how data flows in, how AI components fit into the pipeline, where humans sit in the loop, what the output looks like, and how the user actually engages with it. Thinking in terms of the job the system does for the client, not just the components that make it up.
- Agentic Design \& Trade\-offs — Making considered decisions about when to use agentic approaches versus deterministic pipelines versus human\-in\-the\-loop steps. Understanding the trade\-offs and being able to explain them clearly to the Practice Lead and to clients.
- Hands\-on Build — Writing the code that makes the system work, using AI development tools fluently. Python\-first stack, typically lightweight web frameworks (FastAPI, Gradio) and serverless runtimes (AWS Lambda). AI\-augmented practice is expected and welcomed \- the role is defined by what ships, and real progress for our clients.
- Prompt Engineering \& Model Selection — Designing and refining the prompts, system instructions, and model choices that drive AI behaviour. Balancing accuracy, cost, latency, and privacy against the client's real constraints.
- Data Engineering — Cleaning, structuring, and processing client data into a form the AI layer can work with. Building the ingestion and processing layers that feed the AI components.
- Deployment — Working directly with 923's DevOps team to deploy services to client cloud accounts following 923's deployment standards — source control conventions, commit and PR protocols, secrets management, environment setup, and handover protocols.
- Validation Before Production — Testing AI outputs against real client data before go\-live. Building the dry\-run and validation patterns that let clients sign off on output quality before we enable production writes. Post\-deployment observability is set up to 923 standards.
4\. Project \& Quality Management* Project Tracking — Working from the department's Monday.com board, following established task, branch, and PR conventions. Tickets are written by the Practice Lead during onboarding; over time, you'll draft your own and the Practice Lead will review.
- Client Communication — Joining and running technical portions of weekly client meetings. Initially alongside the Practice Lead and Account Manager; over time, running technical calls solo where the direction is clear. The Account Manager owns the relationship; you own technical clarity.
- Code Review — Submitting clean PRs that pass pre\-commit checks and link to tracked work. Engaging in constructive, question\-based review with the Practice Lead and 923 engineering peers.
- Quality Assurance — Testing AI outputs for failure modes, hallucinations, and edge\-case behaviour before anything reaches a client. Implementing the validation patterns the department uses to build client trust.
- Handover \& Documentation — Completing the delivery checklist before any project closes — documented architecture, credentials handover, runbook, walkthrough video, and third\-party account transfer to client billing.
5\. Working Inside the Department
The department is small, AI\-augmented, and shaping its own way of working as it scales. There's a clear mechanism for new ideas and patterns to become part of how we work — they're tried on real client projects, validated, and then adopted. Until they are, we work the way we work. That's not a constraint on creativity; it's how we stay coherent as a team while we grow.
- Tooling — Using the department's stack — Monday.com for tasks, Notion for capture, Harvest for time, Slack for communication, Fathom for meeting intelligence, the department's Claude skill library for recurring workflows. Friction with the tooling is surfaced to the Practice Lead rather than worked around.
- Idea Flow — Ideas, improvements, and concerns flow through the Practice Lead, who carries them forward to the wider 923 leadership team as appropriate.
- Documentation — Contributing to the department's operating model and shared framework as patterns stabilise from real delivery.
Benefits
- 100% remote job
- Annual paid vacation: 20 working days per year during the first 3 years, further increasing to 25 days in later years
- Paid sick leave and holidays
- Reimbursement of expenses for professional development courses/certifications (up to 100% in agreement with the Manager)
- Well\-being budget
- Health Insurance allowance
- Team and atmosphere: we hire people we trust, so you'll be the part of a strong positive engineering culture, a tightly\-knit team of professionals with a good sense of humor

Role Details
About This Role
AI/ML Engineers build and deploy machine learning models in production. They work across the full ML lifecycle: data pipelines, model training, evaluation, and serving infrastructure. The role has evolved significantly over the past two years. Where ML Engineers once spent most of their time on model architecture, the job now tilts heavily toward inference optimization, cost management, and integrating LLM capabilities into existing systems. Companies want engineers who can ship production systems, and the experimenter-only role is fading fast.
Day-to-day, you're writing training pipelines, debugging data quality issues, setting up evaluation frameworks, and figuring out why your model performs differently in staging than it did on your dev set. The best ML engineers are obsessive about reproducibility and measurement. They instrument everything. They know that a model is only as good as the data feeding it and the infrastructure serving it.
Across the 4,317 AI roles we're tracking, AI/ML Engineer positions make up 70% of the market. At NineTwoThree AI Studio, this role fits into their broader AI and engineering organization.
Demand for AI/ML Engineers has been strong and consistent. Unlike some AI roles that spike with hype cycles, ML engineering is a foundational need. Every company deploying AI models needs people who can keep them running, and the gap between research prototypes and production systems keeps growing.
What the Work Looks Like
A typical week might include: debugging a data pipeline that's silently dropping 3% of training examples, running A/B tests on a new model version, writing documentation for a feature flag system that lets you roll back model deployments, and reviewing a junior engineer's PR for a new evaluation metric. Meetings tend to be cross-functional since ML touches product, engineering, and data teams.
Demand for AI/ML Engineers has been strong and consistent. Unlike some AI roles that spike with hype cycles, ML engineering is a foundational need. Every company deploying AI models needs people who can keep them running, and the gap between research prototypes and production systems keeps growing.
Skills Required
Python and PyTorch dominate the requirements. Most roles expect experience with cloud platforms (AWS, GCP, or Azure) and familiarity with ML frameworks like TensorFlow or JAX. RAG (Retrieval-Augmented Generation) has become a top-3 skill requirement as companies integrate LLMs into their products. Docker and Kubernetes show up in about a third of postings, reflecting the production focus of the role.
Beyond the core stack, employers increasingly want experience with experiment tracking tools (MLflow, Weights & Biases), feature stores, and vector databases. Fine-tuning experience is valuable but less common than you'd think from reading Twitter. Most production LLM work is RAG and prompt engineering, not fine-tuning. If you have both, you're in a strong position.
Companies that are serious about AI/ML hiring tend to post specific infrastructure details in the job description: the frameworks they use, their model serving stack, their data pipeline tools. Vague postings that just say 'ML experience required' without specifics are often companies that haven't figured out what they need yet.
Compensation Benchmarks
AI/ML Engineer roles pay a median of $214,900 based on 6,420 positions with disclosed compensation. Mid-level AI roles across all categories have a median of $194,400.
Across all AI roles, the market median is $215,000. Top-quartile compensation starts at $266,300. The 90th percentile reaches $320,790. For comparison, the highest-paying categories include AI Safety ($287,500) and Research Engineer ($272,100).

Location Context
Across all AI roles, 15% (635 positions) offer remote work, while 3,657 require on-site attendance. Top AI hiring metros: New York (1,650 roles, $220,000 median); San Francisco (1,335 roles, $265,000 median); Los Angeles (708 roles, $214,112 median).
Career Path
Common paths into AI/ML Engineer roles include Data Scientist, Software Engineer, Research Engineer.
From here, career progression typically leads toward ML Architect, AI Engineering Manager, Principal ML Engineer.
The fastest path into ML engineering is through software engineering with a self-directed ML education. A CS degree helps, but production engineering skills matter more than academic credentials. Build something that works, deploy it, and measure it. That portfolio project is worth more than a Coursera certificate. For career growth, the fork comes around the senior level: go deep on technical complexity (staff/principal track) or move into managing ML teams.
What to Expect in Interviews
Expect system design questions around ML pipelines: how you'd build a training pipeline for a specific use case, handle data drift, or design A/B testing infrastructure for model deployments. Coding rounds typically involve Python, with emphasis on data manipulation (pandas, numpy) and algorithm implementation. Take-home assignments often ask you to build an end-to-end ML pipeline from raw data to deployed model.
When evaluating opportunities: Companies that are serious about AI/ML hiring tend to post specific infrastructure details in the job description: the frameworks they use, their model serving stack, their data pipeline tools. Vague postings that just say 'ML experience required' without specifics are often companies that haven't figured out what they need yet.

The AI Job Market Today
The AI job market spans 4,317 open positions across 15 role categories. The largest categories by volume: AI/ML Engineer (3,004), Data Scientist (345), AI Software Engineer (309). These three account for the majority of open positions, though smaller categories often have higher per-role compensation because of specialized skill requirements.
The seniority mix tells a story about where AI teams are in their maturity. Entry-level roles (138) are outnumbered by mid-level (2,071) and senior (1,655) positions, reflecting that most companies are past the 'build a team from scratch' phase and need experienced engineers who can ship production systems. Leadership roles (Director, VP, C-Level) total 453 positions, representing the bottleneck between technical execution and organizational strategy.
Remote work availability sits at 15% of all AI roles (635 positions), with 3,657 requiring on-site or hybrid attendance. The remote share has stabilized after the post-pandemic correction. Senior and specialized roles (Research Scientist, ML Architect) are more likely to be remote-eligible than entry-level positions, partly because experienced hires have more negotiating power and partly because these roles require less hands-on mentorship.
AI compensation is structured in clear tiers. The market median sits at $215,000. Top-quartile roles start at $266,300, and the 90th percentile reaches $320,790. These figures include base salary with disclosed compensation. Total compensation (including equity, bonuses, and sign-on) runs 20-40% higher at companies that offer those components.
Category matters for compensation. AI Safety roles lead at $287,500 median, while Prompt Engineer roles sit at $145,000. The spread between highest and lowest-paying categories reflects the premium on specialized technical skills versus broader analytical roles.
The most in-demand skills across all AI postings: Python (2,249 postings), Aws (1,224 postings), Azure (938 postings), Rag (915 postings), Gcp (660 postings), Pytorch (640 postings), Prompt Engineering (624 postings), Kubernetes (559 postings). Python dominates, appearing in the vast majority of role descriptions regardless of category. Cloud platform experience (AWS, GCP, Azure) is the second most common requirement.
