About the role
FusionAuth is hiring a Staff Software Engineer to operate as a senior hands-on engineer. This is a deeply hands-on technical role : you solve the most complex problems, and the rest of the job (review, technical design, mentorship) grows out of that credibility rather than sitting apart from it. Found on 1752vc Careers, the job board for startup and VC roles.
What they're looking for
- Education: Bachelor's degree in Computer Science or equivalent demonstrable technical depth
- Experience: 10+ years of professional software engineering, with demonstrated staff-level technical competency
- Hands-on development: Currently writes and ships production code. This role stays in the code, so recent, active engineering is required
- CIAM protocol depth: Production-grade experience with OAuth 2.x, OIDC, and SAML, including the ability to identify subtle misimplementations, guide protocol-correct designs, and handle federation and security edge cases
- Java proficiency: Strong Java skills, including a working understanding of the JVM. FusionAuth's core application is Java-based
- Database depth: Experience tuning PostgreSQL (or a comparable relational database) at scale
