About the role

You won't be plugging into someone else's architecture - you'll be deciding what the architecture should be.

Design agent systems from first principles.
Drive evaluation rigor. Build evals before you build the agent. Diagnose where it fails, fix the root cause, and prove the fix moved the metric.
A meaningful fraction of your day will be spent driving Claude Code, Codex, and similar tools to plan, scaffold, refactor, and debug your own work.

2-4 years of applied ML / AI engineering experience with a Bachelor's in CS, Math, Engineering or equivalent - or a Master's in a similar program with no prior industry experience required.
Hands-on experience with at least one major agent SDK - OpenAI Agents SDK, Anthropic SDK / claude-agent-sdk, LangGraph, or equivalent - and an opinion on the tradeoffs.
Working knowledge of how modern coding agents are built and how they engineer context - what goes in the system prompt, how files are read and edited, how long-running tasks are planned and tracked, where they break.
A bias toward measurement: you don't ship without an eval, and you don't believe a number you can't reproduce.
We participate in E-Verify as required by applicable law.

Production experience with caching, observability, and cost control on LLM workloads.
Work from anywhere in the US!
Machinify is digital-first.
Experience designing structured outputs (Pydantic / JSON Schema) and tool interfaces that LLMs reliably call correctly.
Familiarity with reasoning models (o-series, Claude extended thinking, Gemini thinking) and a sense of when they earn their cost.
Prior work on long-context, citation-grounded systems where the model must point to evidence, not just answer.
Strongly preferred

Flexible and trusting environment where you'll feel empowered to do your best work
Compensation also includes meaningful equity, healthcare, unlimited PTO, and more.

Engineer the context. The hardest part of building a good agent is what goes into the prompt and what comes out. You'll obsess over context windows, tool surfaces, structured outputs, citation grounding, and the prompt itself.
