Software Engineer (Developer Experience)

Join Cape, a cutting-edge engineering team focused on building cryptographic primitives, 5G core network functions, zero-trust edge systems, and threat detection pipelines. As a Developer Experience Engineer, you will own the internal platforms, tooling, and workflows that engineering depends on, making Cape's engineers faster, less frustrated, and more confident in their work. You will work closely with platform, product, and security teams, and your impact will be felt by every engineer at Cape.

• Construire et maintenir les outils internes, les scripts et les SDK utilisés par les ingénieurs de Cape au quotidien, de la configuration du projet à la configuration du développement local.
• Posséder la stratégie de développement assisté par l'IA de Cape, évaluer, intégrer et configurer les outils de codage IA pour que les ingénieurs obtiennent des suggestions de haute qualité.
• Identifier les points de friction au sein de l'organisation d'ingénierie et prioriser et éliminer ces problèmes. Contribuer aux normes d'ingénierie concernant les tests, la révision du code et les pratiques de déploiement.
• Strong understanding of containerization and orchestration: Docker, Kubernetes, or other containers
• A track record of identifying developer friction, building solutions, and measuring the improvement — not just shipping tooling
• 4+ years of software engineering experience, with meaningful time spent on internal platforms, developer tooling, or infrastructure
• Strong written and verbal communication skills — you can explain infrastructure tradeoffs to engineers who didn't ask for a lecture and write docs that actually get read
• Fluency in at least one modern backend language — Go is strongly preferred; Python, TypeScript, or Rust also welcome
• Hands-on experience improving and optimizing CI/CD systems (GitHub Actions, Buildkite, Bazel, or similar) at engineering-team scale
• Experience building developer platforms in security-constrained environments (FedRAMP, DISA STIGs, or government compliance frameworks)
• Familiarity with software supply chain security: artifact signing (Sigstore, Cosign), SBOM generation, dependency auditing
• Experience at a high-growth startup where the engineering team scaled rapidly and tooling had to keep pace
• Background in observability tooling: distributed tracing, metrics pipelines, and making complex systems legible to engineers
• Active U.S. security clearance or eligibility and willingness to obtain one
• Experience integrating AI coding assistants (GitHub Copilot, Claude Code, Cursor, or similar) into engineering workflows, including prompt tuning, context management, and measuring productivity impact
