Senior Software Engineer, Developer Experience
Own internal developer platforms, CI/CD pipelines, AI-assisted tooling, and local dev environments to make Cape engineers faster and more confident. Report to engineering leadership and partner across platform, product, and security teams.
About the job
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
