Come join our engineering team in a hands-on technical role at the heart of a new discipline: Harness Engineering. As AI coding agents take on more of the software lifecycle, the hard part is no longer writing code - agents generate it faster than humans can review it, so the bottleneck shifts to verification and trust. Harness Engineering exists to break that bottleneck: engineering the environment that steers agents toward correct, maintainable, well-architected output so that quality is enforced by the system, not re-audited by a person on every change. We call that environment the harness (Agent = Model + Harness). As a Lead Harness Engineer youll build and own the individual controls that make up that harness, working end-to-end from problem to production.
Responsibilities - Design, develop, deploy, and support components of the harness - the guides, feedback loops, guardrails, and shared context that turn raw model capability into production-grade engineering. This is a hands-on role focused on systems and leverage, not hand-writing application code.
- Build feedforward guides - agent instruction files, reusable skills, architectural rules, reference docs, and codemods - that help agents get it right the first time.
- Build feedback sensors - custom linters, static analysis, structural and architecture-fitness tests, verification loops, and LLM-as-judge reviewers - that catch issues before they reach human reviewers.
- Run the steering loop - when an agent repeats a mistake, engineer a control so it cant happen again - and help keep repository knowledge (docs, specs, context) legible to agents, fighting drift.
- Contribute to quality gating and release criteria, and to LLM testing that ensures AI-generated output meets quality and safety thresholds.
- Help improve observability into agent work and track the measures that matter - cost per merged PR, time-to-merge for agent-assisted PRs, review velocity relative to PR size, defect escape rate, and agent-PR survival rate.
- Evaluate the stability, compatibility, scalability, interoperability, and performance of harness components.
- Continually learn new techniques in agent-augmented engineering, and serve as a source of technical expertise and mentor to junior team members.
- Bachelors/Masters in Computer Science or related disciplines, or relevant experience in software architecture, design, development, and testing.
- Strong software engineering background; youve worked in large codebases and care about architecture, testing, and maintainability.
- Comfortable building tooling across a modern stack - linters and static analysis, CI pipelines, containerized build/test environments, and instrumentation/observability - and familiar with agent instruction conventions such as Agents.md.
- Hands-on experience with AI coding agents (e.g. Claude Code, Codex, or similar) and a feel for where they succeed and fail.
- Experience with spec-driven development, context engineering, agent orchestration, fitness functions, and developer-platform work.
- A systems mindset - youd rather fix the environment than fix one output - and the ability to encode "what good looks like" into mechanical, repeatable rules.
- Judgement about when to reach for deterministic, computational controls (type checkers, linters, structural/architecture-fitness tests) versus inferential, LLM-based ones (AI code review, LLM-as-judge) - and an understanding of the cost, speed, and reliability trade-offs between them.
- Clear communicator; able to articulate design with architects and discuss strategy and requirements with teams.
