We're hiring a Software Engineer II to join the Core Services team, which is the platform team that authentication, authorization, identity, and account management across Censys are built on. In this role you'll work alongside experienced engineers to extend our RBAC controls, build new capabilities like group management, build event pipelines, and help evolve the public Censys API.

Design and build new platform features including group management and expanded functionality to our existing enterprise authentication mechanisms (SAML / SCIM)
Implement clean, well-tested microservices with clear APIs and proper error handling
Partner with product and engineering stakeholders to clarify requirements, drive technical decisions on features you own, and ship on a regular cadence
Share on-call responsibilities for the services the team owns and handle straightforward incidents with the team supporting
Contribute to the developer experience for both internal teams and external API consumers as platform capabilities grow
What You'll Bring
2-4 years of software engineering experience
Solid Go (Golang) implementation skills — clean code, idiomatic error handling, effective use of the standard library
Experience building and shipping backend services in a cloud environment (GCP or AWS)
A track record of delivering feature work at high quality and seeing it through to production
Strong ownership instinct and drive, to identify what needs to be done, ask the right questions early, and follow through
Clear communication and the ability to collaborate effectively with product and engineering stakeholders
What Sets You Apart
Familiarity with identity concepts: SSO, SAML, OIDC, or SCIM
Experience with Kubernetes and Docker
Comfort in a distributed systems context
