Software Engineer (Identity and Authorization)

• The largest, most demanding enterprises run on Baseten, and they bring exacting requirements for how people, services, and agents access the platform. This is the founding role for our identity and authorization team within enterprise engineering. You’ll own the identity and access layer of the Baseten platform: the authorization model, credential systems, and admin experiences that enterprise IT teams use to govern access for organizations like Harvey, HubSpot, and Notion
• You’ll design and build Baseten’s fine-grained authorization system from the ground up to support the workflows customers depend on today while giving them cleaner, more precise ways to manage access as the platform grows. Authorization at Baseten requires low-latency permission checks at high request volume, consistent contracts and behaviors across the product suite, and strong security guarantees for mission-critical, highly regulated workloads
• Lead identity and authorization projects from problem definition and technical design through implementation, launch, and iteration
• Design authorization and credential models that support critical user workflows today and can be safely extended as the platform evolves
• Partner with product, design, and customer-facing teams to turn enterprise security requirements into durable technical solutions
• Establish engineering practices for quality, security, observability, and operational ownership
• Provide technical leadership and mentorship as the team grows
• Recent and upcoming work in this area:
• Fine-grained authorization for users, service accounts, and agentic workloads: per-resource permissions at the organization, team, and workload scope to support both common workflows and complex enterprise access policies
• Programmatic authentication allowing high-compliance customers to connect service principles securely via short-lived, workload-based credentials
• Agent credentials that grant an agent exactly the access it needs for the given task and nothing more
• Enterprise identity lifecycle including single sign-on, SCIM provisioning, and per-organization session expiry policies
• Admin controls for centralized visibility, auditability, and governance over credentials, roles, and access

Benefits

• Remote-first work environment. The Baseten team is welcome to work from wherever they want; fully remote, in our San Francisco office, or a mix of both. Today, our team (including our founding team) is spread across the United States, Canada, and Armenia. We provide a $1,000 stipend for you to make your home-office comfortable and productive
• Regular in-person team summits. We get together as a team three times a year to plan, workshop, and most importantly, get to know each other better
• Unlimited PTO. We ask that everyone take at least 4 weeks of vacation. And we have a company-wide break between Christmas and New Year’s Day
• Full healthcare coverage. Medical, dental and vision insurance for you and your family
• Paid parental leave. 16-weeks fully paid parental leave (adoptive and non-birth parents included) and flexibility with schedules while returning to work
• Company-sponsored 401(k) for you to contribute to
• Learning and development budget. We encourage you to take classes, attend conferences, and invest in your craft and we’ll cover expenses to make it happen- Demonstrated end-to-end ownership: you’ve taken a system from first design through implementation, production rollout, and iteration with users
• Comfort working across the full stack, from product and application code to cloud and Kubernetes infrastructure
• Experience developing and operating multi-tenant systems at scale, where authorization checks sit in the request path and latency and consistency matter
• 4-5+ years of experience building production backend systems, including hands-on design and implementation of a product authorization system: per-resource or per-object permissions, relationship-based access control, a policy engine, or a fine-grained authorization system in the style of Zanzibar, OpenFGA, SpiceDB, or Cedar
• Experience with Python and Go
• Experience running an OpenFGA, SpiceDB, or similar deployment in production, beyond a proof of concept
• Working knowledge of OAuth, OIDC, and SCIM at the protocol level
