Full Job Description

đź“‹ Description

  • • Secure-by-default guardrails: Build the patterns, libraries, and secure-by-default standards (authentication, authorization, input handling, cryptography) that make whole classes of vulnerabilities hard to introduce, and review Go and Rust for security.
  • • Threat modeling and secure design: Partner with engineering teams on new features and architectural changes across a distributed, polyglot system, and turn the results into concrete design decisions.
  • • Software supply chain: Own dependency integrity, artifact signing, and build-pipeline trust. This matters especially for the self-managed and air-gapped deployments our customers run.
  • • Developer-facing security tooling: Extend the app sec toolchain in CI/CD — SAST, software composition analysis, secret scanning, and fuzzing — and keep it high-signal, tuning it so findings are accurate and actionable for developers rather than noise. Partner with the owning teams to drive real risks to remediation.
  • • Raise engineering's security fluency: Through design reviews, documentation, and direct collaboration, help the whole org build securely by default.

🎯 Requirements

  • • 5+ years building production software, including hands-on security ownership of a real codebase. You are a software engineer first, applying that skill to security.
  • • Ability to read and review either Go and/or Rust with fluency. You don't need to have shipped both, but you should be able to reason about security in our stack from day one.
  • • Strong grounding in application security fundamentals: web and API vulnerability classes, authentication and authorization patterns, and applied cryptography.
  • • Experience with threat modeling and secure design review on non-trivial, distributed systems.
  • • Hands-on experience embedding security tooling (SAST, SCA, secret scanning) into developer workflows and CI/CD; tuning it for signal over noise.

🏖️ Benefits

  • • Salary range: $180,000 - $230,000 per year.
  • • Plus equity and benefits.
  • • Eligibility: U.S. Citizenship Required.
