DESCRIPTION

---------------

Alexa AI is building the next generation of Alexa\+, Amazon's LLM\-powered conversational assistant, and its future is agentic: LLM systems that reason and act over dozens of chained inferences, coupled to real environments where their actions persist. Making these agents smarter, faster, and cheaper is as much a systems problem as a modeling problem \- agent performance depends on the model, the harness, the evaluation infrastructure, and the serving stack co\-designed together.

We are looking for a Senior Machine Learning Engineer to build and own core systems in this agentic platform. You will take one of its foundational areas \- agentic evaluation infrastructure, reinforcement learning training systems, self\-learning pipelines, or agentic inference serving \- and own it end to end: the design, the implementation, the operational bar, and the interfaces that scientists and partner teams build on. You will work directly with applied scientists, work backwards from committed product launches, and turn research prototypes into infrastructure that runs unattended at scale.

The work is concrete. Agents are evaluated in sandboxed, recreatable environments at hundreds of concurrent trials, and every source of infrastructure noise you remove is a model decision the organization can trust. They are trained on long\-horizon multi\-turn trajectories where the rollout and learner engines have to agree token for token. They are served under latency budgets measured in hundreds of milliseconds. And they improve week over week only if the pipeline that turns production experience into training data actually holds. You will own a piece of that loop, make it reliable, and make it fast.

This is a platform role with room to grow. The systems you own serve every Alexa agent program rather than a single product, and the engineer who makes them dependable becomes the person the organization routes its hardest cross\-system problems to.

Key job responsibilities

Design, build, and operate major components of the agentic AI platform: evaluation harnesses, sandboxed environments and mocked resources, RL and post\-training pipelines, self\-learning data pipelines, or inference serving for agentic traffic

Lead the design work in your area: write the design documents, drive them through review, and make the build\-versus\-adopt calls within your scope

Own reliability and performance: instrument your systems, drive down the failure modes that make results untrustworthy (process management, resource contention, unreliable external calls), and report platform health in metrics rather than anecdotes

Partner with applied scientists to turn research code into production infrastructure, and expose it through interfaces other teams can use without your involvement

Scale what you build: hundreds of concurrent evaluation trials, long\-context multi\-turn training jobs, and large GPU formations on shared company infrastructure

Raise the engineering bar through code and design reviews, operational excellence practices, and deep dives on cross\-system problems

Mentor engineers earlier in their careers and help set technical direction for your team

A day in the life

You might spend the morning making the evaluation platform reproducible under high concurrency, tracking down why scores drift when a hundred trials share a host, midday pairing with a scientist to get a long\-context training job to converge identically across the rollout and learner engines, and the afternoon in a design review deciding how environment snapshots should be versioned and served to partner teams. You work daily with applied scientists and other engineers, and your systems are the reason their results are trustworthy and shippable.

About the team

Our organization owns the applied science and platform engineering for Alexa's agentic experiences. We operate at the intersection of large language models, reinforcement learning with verifiable rewards, agentic architectures, and large\-scale distributed systems, serving customers across dozens of languages and device types. Our platform provides the shared evaluation, training, self\-learning, and serving foundation for Alexa's flagship agent programs and the broader agent portfolio behind them.

BASIC QUALIFICATIONS

------------------------

  • 5\+ years of non\-internship professional software development experience
  • 5\+ years of programming with at least one software programming language experience
  • 5\+ years of leading design or architecture (design patterns, reliability and scaling) of new and existing systems experience
  • Experience as a mentor, tech lead or leading an engineering team

PREFERRED QUALIFICATIONS

----------------------------

  • 5\+ years of full software development life cycle, including coding standards, code reviews, source control management, build processes, testing, and operations experience
  • Bachelor's degree in computer science or equivalent

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 Amazon.com, 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.

Skills Required

Drift Ai (2% 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.
