About the role
- The people doing that work deserve an environment that gets out of their way.
- As a Developer Experience Engineer, your job is to make Cape's engineers measurably faster, less frustrated, and more confident in what they ship.
- That means owning the internal platforms, tooling, and workflows that engineering depends on - from CI/CD pipelines and local development environments to AI-assisted development workflows, test infrastructure, and release processes.
Responsibilities
- We didn't just build a layer on top of old tech; we built America's most private and secure mobile carrier from the ground up.
- 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
- Cape's engineering team is small by design and ambitious by nature.
- We build cryptographic primitives, 5G core network functions, zero-trust edge systems, and threat detection pipelines - problems that don't have StackOverflow answers.
Nice to have
- 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
- Experience integrating AI coding assistants (GitHub Copilot, Claude Code, Cursor, or similar) into engineering workflows, including prompt tuning, context management, and measuring productivity impact
- Active U.S. security clearance or eligibility and willingness to obtain one
- Family-forming needs
Skills
- Evaluate and introduce new tools thoughtfully - instrument adoption, gather feedback, and deprecate what isn't working
Compensation
- We offer competitive compensation that is geo-adjusted based on your location, along with meaningful equity so you share in the value you help create.
Benefits
- 100% coverage of medical, dental, and vision premiums for you and your dependents
- 12 weeks paid parental leave (for all parents, no waiting period)
- We hire without regard to race, color, ancestry, religion, sex, national origin, sexual orientation, gender identity, age, marital status, disability, or Veteran status.
- We believe companies exist to build awesome things and take care of the people who build them, so we offer top-tier healthcare, 401(k) matching, and a generous vacation policy that our team actually uses to recharge.
Company info
- At Cape, we are the architects of a privacy-centric movement that is just getting started.
- We are relentless builders, constantly innovating at the edge of what's possible in telecommunications.
- We operate on a foundation of high trust and high expectations.
- Our structure is flat, and collaboration matters more than hierarchy.
- As a member of our team, you will collaborate with world-class engineers, architects, and visionaries, and work across organizational lines to solve "impossible" problems and deliver mission-critical results for our users every single day.
- ARE YOU THE CANDIDATE WE ARE LOOKING FOR?
- Our mission is to be a force for good in global wireless.
- Cape was founded in 2022 by people who believe privacy is a fundamental right, not a luxury to be traded away.
- By building our own network from scratch, we are able to design and build a suite of privacy and security features that no other carrier on the planet can offer.
- We closed our Series C in March 2026, and we are scaling rapidly, with the goal of giving people back control of their most personal information.
