Join our world-class team today and fulfill your career potential!\nThe Opportunity\nCome 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 theharness(Agent = Model + Harness). As a Lead Harness Engineeryou'llbuild and own the individual controls that make up that harness, working end-to-end from problem to production.\nWhat You’ll Contribute\nDesign, 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.\n\nBuild feedforward guides - agent instruction files, reusable skills, architectural rules, reference docs, and codemods - that help agents get it right the first time.\n\nBuild 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.\n\nRun the steering loop - when an agent repeats a mistake, engineer a control so it can't happen again - and help keep repository knowledge (docs, specs, context) legible to agents, fighting drift.\n\nContribute to quality gating and release criteria, and to LLM testing that ensures AI-generated output meets quality and safety thresholds.\n\nHelp 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.\n\nEvaluate the stability, compatibility, scalability, interoperability, and performance of harness components.\n\nContinually learn new techniques in agent-augmented engineering and serve as a source of technical expertise and mentor to junior team members.\n\nWhat We’re Seeking\nBachelor's/Master's in Computer Science or related disciplines, or relevant experience in software architecture, design, development, and testing. \nStrong software engineering background; you've worked in large codebases and care about architecture, testing, and maintainability. \nComfortable 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. \nHands-on experience with AI coding agents (e.g. Claude Code, Codex, or similar) and a feel for where they succeed and fail. \nExperience with spec-driven development, context engineering, agent orchestration, fitness functions, and developer-platform work. \nA systems mindset - you'd rather fix the environment than fix one output - and the ability to encode \"what good looks like\" into mechanical, repeatable rules. \nJudgement 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. \nClear communicator; able to articulate design with architects and discuss strategy and requirements with teams. \nOur Offer to You\nAn inclusive culture strongly reflecting our core values: Act Like an Owner, Delight Our Customers and Earn the Respect of Others.\nThe opportunity to make an impact and develop professionally by leveraging your unique strengths and participating in valuable learning experiences.\nHighly competitive compensation, benefits and rewards programs that encourage you to bring your best every day and be recognized for doing so.\nAn engaging, people-first work environment offering work/life balance, employee resource groups, and social events to promote interaction and camaraderie.\nThe targeted base pay range for this role is: $105,000 to $165,000 with this range reflecting differences in candidate knowledge, skills and experience.\nWhy Make a Move to FICO?\nAt FICO, you can develop your career with a leading organization in one of the fastest-growing fields in technology today - Big Data analytics.
