Senior Software Engineer, Developer Experience

What You'll Own

CI/CD and Build Infrastructure

• Own and continuously improve Cape's continuous integration and deployment pipelines — build times, flakiness rates, parallelism, caching, and test isolation are your KPIs
• Design and implement infrastructure that enables engineers to go from code to deployed artifact quickly and with high confidence
• Drive reliability improvements that eliminate common failure modes: flaky tests, non-reproducible builds, slow pipelines, and environment drift
• Instrument and measure the development pipeline end-to-end — establish baselines, track trends, and surface bottlenecks

Developer Tooling and Environments

• Build and maintain the internal tooling, scripts, and SDKs that Cape engineers use daily — from project scaffolding and local dev setup to testing utilities and debugging aids
• Own the local development environment story: containerized setups, secrets management, service dependencies, and onboarding time for new engineers
• Evaluate and introduce new tools thoughtfully - instrument adoption, gather feedback, and deprecate what isn't working
• Write the documentation and runbooks that make complex infrastructure accessible to engineers

AI Tooling and AI-Assisted Development

• Own Cape’s AI-assisted development strategy - evaluate, integrate, and configure AI coding tools (code completion, automated review, agentic coding assistants)
• Build guardrails and context systems that make AI tools effective in Cape’s codebase - prompt engineering for internal tooling, retrieval-augmented generation over internal docs
• Measure the productivity impact of AI tooling rigorously - track adoption, code acceptance rates, time savings, and quality metrics
• Stay ahead of the rapidly evolving AI development tooling landscape

Platform Reliability and Security Constraints

• Build developer tooling within Cape's security and compliance constraints — FedRAMP-adjacent controls
• Partner with security engineering to ensure that developer tooling doesn't become an attack surface — secrets handling, artifact signing, dependency provenance, and supply chain integrity
• Own the reliability and operational health of internal developer platforms — treat them like production systems

Engineering Culture and Standards

• Identify patterns of friction across the engineering organization through observation, surveys, and direct partnership with teams
• Contribute to engineering standards around testing, code review, and deployment practices
• Set a high bar for the developer experience through your own work

Requirements

• Proven track record of tackling hard problems
• Experience building and maintaining CI/CD pipelines, developer tooling, and internal platforms
• Strong understanding of containerization, secrets management, and local development environments
• Experience with AI coding tools and agentic development workflows
• Ability to work within security and compliance constraints (FedRAMP-adjacent controls)
• Excellent documentation and communication skills
