Partner with engineers on testing, audits, incident response, and ongoing security improvements in a privacy-first environment

What We’re Looking For

5+ years of experience in application, product, or software security engineering
Strong understanding of common application security risks, including authentication, authorization, API security, and cryptographic misuse
Experience securing production backend systems and developer platforms, with the ability to reason about systems-level code (Rust a strong plus)
Familiarity with modern secure software development practices, authentication systems, and key management
Clear communicator with a pragmatic security mindset suited to high-trust, fast-moving engineering teams

Benefits

Monthly budget for expenses relating to working in a remote environment (home office setup & supplies, transportation, fitness & personal well-being, continued learning, etc.).

Regular team off-sites and retreats.
