AI job market dashboard showing open roles by category

Are you a senior engineer who can keep large, AI\-augmented systems running

reliably at Apple scale? Apple's Stability Engineering team is looking for a

seasoned engineer to join our Core team in San Diego. We build and operate the

platforms, services, and infrastructure that turn crash reports from Apple

devices into actionable engineering insights. You'll work on systems where

LLMs and agents are already part of the production fabric \- evolving them,

hardening them, and using AI tools to extend what a small team can deliver.

Description

Our team owns the end\-to\-end platform behind stability analysis at Apple:

symbolication of crash logs across the company's hardware portfolio, the data

pipelines that aggregate and cluster crash logs, and the applications and

services that engineers across Apple use every day to drive operating\-system

quality. This role is about keeping that platform healthy, extending it

deliberately, and making the engineering team itself more effective by using

AI tools well.

Day to day, you'll spend most of your time on the engineering work of running

real systems: tuning evaluation infrastructure, tightening operational

controls, improving auditability and debug trails, and scaling the workflows

our analysts rely on. When new capabilities are needed, you'll prototype and

integrate them into the platform. You'll partner closely with stability

analysts who are domain experts in OS reliability, and with the broader team

responsible for symbolication, ETL, and service infrastructure. You'll also

be expected to use AI\-assisted development tools fluently to investigate

issues, refactor at scale, and ship more with a small team.

We're looking for someone with the rigor of a seasoned production engineer

who is also comfortable operating systems that include LLMs and agents as

first\-class components. If you enjoy taking responsibility for a complex,

already\-running platform and making it steadily better, we want to talk.

Preferred Qualifications

Experience operating LLM\- or agent\-based features in production environments over time

Experience building or maintaining evaluation harnesses, audit trails, or

replay infrastructure for AI systems

Background in developer tools, observability, crash/stability analysis, or other operating\-system\-quality domains

Familiarity with one or more of: Ruby on Rails, Node.js/TypeScript, Python for production services

Experience working in environments with significant deferred scalability work (capacity\-constrained, long\-lead\-time infrastructure)

Minimum Qualifications

5\+ years of professional software engineering experience building and operating production systems

BS in Computer Science or a related field, or equivalent practical experience

Fluent use of AI\-assisted development tools (coding agents, code review assistants, etc.) to work effectively at scale

Demonstrated experience designing and scaling distributed systems (load balancing, active\-active topologies, capacity planning, throughput\-bound services)

Track record of maintaining and evolving production services \- observability, operational controls, incident response, and steady iteration on existing systems

Strong full\-stack instincts; comfortable spanning data infrastructure, backend services, and the user\-facing surfaces that consume them

Proven ability to operate independently on ambiguous, open\-ended problems where the right answer is not obvious

Pay \& Benefits

At Apple, base pay is one part of our total compensation package and is determined within a range. This provides the opportunity to progress as you grow and develop within a role. The base pay range for this role is between $139,500 and $258,100, and your base pay will depend on your skills, qualifications, experience, and location.

Apple employees also have the opportunity to become an Apple shareholder through participation in Apple's discretionary employee stock programs. Apple employees are eligible for discretionary restricted stock unit awards, and can purchase Apple stock at a discount if voluntarily participating in Apple's Employee Stock Purchase Plan. You'll also receive benefits including: Comprehensive medical and dental coverage, retirement benefits, a range of discounted products and free services, and for formal education related to advancing your career at Apple, reimbursement for certain educational expenses \- including tuition.

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 4,133 AI roles we're tracking, AI/ML Engineer positions make up 69% of the market. At Apple, 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.

Skills Required

Python (51% of roles) Typescript (7% of roles)

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.

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.
