Principal Engineer- Agentic Development
Level inferred from job title
Job description
Software engineering role at FICO focused on directing, specifying, and verifying the output of AI coding agents within a structured harness, taking ownership of agent-generated code through to deployment in a regulated decisioning context.

- Remote
What you'll do
- Collaborate with Product teams to translate early stage ideation into structured Proof of Concepts, establishing clear technical feasibility and scope.
- Produce detailed specifications and acceptance criteria that enable coding agents to generate correct, maintainable, and well-architected output, taking full ownership of the resulting code through to deployment.
- Apply rigorous quality standards to all agent generated output, ensuring it meets the same level of scrutiny as hand written code within a regulated decisioning context.
- Operate effectively within the agentic harness, utilising established guides, including AGENTS.md files, architectural rules, and reference documentation alongside automated sensors such as linters, fitness tests, verification loops, and LLM-as-judge reviewers.
- Identify the root cause of recurring agent errors and work with the harness team to implement systemic controls, ensuring the same class of failure cannot recur across the codebase.
- Maintain the accuracy and currency of repository documentation, specifications, and contextual knowledge, treating these as a shared system of record for both human engineers and agents.
- Apply focused technical judgement to architecture decisions, edge case analysis, latency and integration risk, auditability requirements, and any determination that falls outside the appropriate scope of agent autonomy.
What we're looking for
- Demonstrable experience in software engineering within large, complex codebases, with a strong foundation in software architecture, testing practices, and long-term maintainability.
- Practical experience working with AI coding agents such as Claude Code, GitHub Copilot, Codex, or Cursor with a clear understanding of their capabilities, limitations, and appropriate use within a production engineering workflow.
- The technical judgement to critically evaluate agent generated output, identify subtle errors or architectural weaknesses, and make informed decisions about when to intervene in the agent workflow.
- The ability to communicate technical requirements with precision, producing specifications and definitions of done that are unambiguous, testable, and actionable by both agents and engineering colleagues.
- A disciplined approach to verification, instinctively questioning correctness, building appropriate checks and test coverage, and applying particular rigour in regulated and mission-critical delivery contexts.
- A results-oriented approach to delivery, with accountability for the quality and correctness of shipped work rather than volume of code produced.
- Familiarity with relevant technologies including Python, SQL, JavaScript/TypeScript, AWS or Azure, Kubernetes, CI/CD pipelines, ML model deployment, or real-time decisioning systems.
Nice to have
- Experience with spec-driven development, context engineering, or agent orchestration in a team environment.
- Knowledge of regulated or audited software delivery processes and controlled change management.
- A background in decisioning, credit risk, fraud detection, analytics, optimisation, or data engineering.
- Candidates who can also articulate a considered approach to human-AI collaboration including delegation boundaries, human oversight, and earning autonomy through demonstrated quality.
