Software Engineer, Developer Experience

We are looking for a Developer Experience Engineer with 4+ years of experience to join Cape — America's privacy-first mobile carrier — and make every engineer on the team measurably faster. Cape recently closed its Series C and is scaling its engineering org from ~70 to well beyond that, making this the perfect inflection point to bring on a high-agency, senior engineer who can own the internal platforms, CI/CD pipelines, and developer tooling that the entire organization depends on. You'll be the first dedicated DevEx hire, with the potential to grow into a tech lead or manager as the function scales. This is a product role where your customers are world-class engineers building cryptographic primitives and 5G core network functions — and your job is to get out of their way.

What will you be doing?

• Own and improve Cape's CI/CD pipelines, local development environments, and internal tooling to eliminate friction across the entire engineering org — with a particular focus on improving how the team writes and ships Go

• Work cross-functionally with platform, product, infrastructure, network, and security teams to identify pain points, prioritize the highest-impact improvements, and ship solutions that make engineers faster

• Evaluate and shape Cape's AI-assisted development strategy — deciding what tools to adopt, building guardrails, and measuring real productivity impact

• Establish developer experience standards, documentation, and runbooks that scale with the team as Cape grows aggressively post-Series C

• Act as a high-ownership, senior technical leader who can mentor future DevEx hires and tell the team what they should be doing better — not just execute on a predefined roadmap
