About the role

Senior Software Engineer developing identity & authorization platform services at ClickHouse. Designing and building authentication and authorization infrastructure for a cloud-based data analytics solution.

Responsibilities

Design and build the platform services that power authentication, authorization, and audit across ClickHouse Cloud. This includes a unified RBAC/ReBAC service, token issuance and session handling, and the SDKs that product teams embed to make authorization decision.
Model permissions and access control primitives (resources, roles, relationships, policies) that work across ClickHouse, SQL Console, ClickPipes, and HyperDX. Ship the libraries and APIs that other engineers build against.
Implement protocol-level support for SAML, SCIM, OIDC, OAuth2, and MFA/passwordless flows. Own the integrations that make enterprise SSO and provisioning work end to end.
Build the audit and authorization-decision telemetry pipeline so every access decision is observable, queryable, and surfaceable to customers.
Partner with product engineering teams to migrate bespoke per-product auth implementations onto the shared platform, and design APIs that make adoption straightforward.
Carry the platform on-call rotation and own production reliability for systems on the critical path of every customer request.

Minimum 4+ years building production backend systems at scale. Comfort with at least one systems language (Go, Rust, C++) and one application language (TypeScript, Python).
Hands-on experience designing and implementing an authentication or authorization service. Examples include building a token issuer, an OIDC or OAuth2 provider, a policy engine, a permissions model, or an FGA/ReBAC system in the style of Zanzibar, OpenFGA, SpiceDB, or Cedar.
Working knowledge of SAML, SCIM, OIDC, and OAuth2 at the protocol level and are able to implement them.
Experience designing APIs and SDKs that other engineers depend on, with strong opinions on what makes them adoptable.
Experience operating distributed systems at scale, including caching strategies, consistency tradeoffs, and multi-region concerns.
Familiarity with identity vendors (Auth0, WorkOS, AWS/GCP/Azure IAM) as building blocks you've extended or integrated into a larger platform.
Strong production debugging instincts and a high bar for systems that are easy to develop against.
