The Security Platform team is responsible for building the authentication, authorization, and identity infrastructure that underpins Vannevar's mission-critical software. This role offers the opportunity to own full-stack development across a security platform serving the national security, defense, and intelligence communities.
Key responsibilities include:

- Own the internal self-service platform for user, group, and permission management, partnering with design to create intuitive experiences for developers and mission teams
- Build tooling and visualizations to help developers, administrators, and mission users understand and validate access permissions
- Own and evolve platform management interfaces, including the feature flag system, to support new products and customer needs
- Partner with product engineering teams to build shared authorization and resource-sharing capabilities
- Shape the long-term roadmap for the Security Platform team by driving scalable platform capabilities and improving developer experience
You'll work closely with product engineers, designers, compliance and application security teams, forward-deployed engineers, and mission users to build security capabilities that are intuitive, scalable, and deeply integrated into the product experience.
Required qualifications:
- 7+ years of software engineering experience with a strong track record of designing, building, and operating scalable backend systems
- Strong backend expertise in modern languages (Python, Java, etc.), relational databases (PostgreSQL), distributed systems, and API design
- Comfortable owning end-to-end development including frontend work (React/TypeScript/Node.js) with focus on polished customer-facing experiences
- Strong product intuition with ability to make pragmatic technical decisions and balance user needs with engineering tradeoffs
- Experience with identity and authentication concepts including OAuth 2.0, OpenID Connect, SAML, JWTs, session management, RBAC/ABAC, SSO, Keycloak, OpenFGA, or similar systems
- Excellent cross-functional collaboration and communication skills
Nice to have: Active security clearance or ability to obtain one; prior user-facing product experience; willingness to travel to visit users and debug issues.
