Description

  • Design and build platform services for authentication, authorization, and audit across ClickHouse Cloud.
  • Develop a unified RBAC/ReBAC service, token issuance, session handling, and SDKs used by product teams.
  • Model permissions and access-control primitives that work across ClickHouse, SQL Console, ClickPipes, and HyperDX.
  • Implement protocol-level support for SAML, SCIM, OIDC, OAuth2, and MFA/passwordless flows.
  • Own enterprise SSO and provisioning integrations end to end.
  • Build the audit and authorization-decision telemetry pipeline so access decisions are observable and queryable.
  • Partner with product engineering teams to migrate product-specific auth systems onto the shared platform.
  • Design APIs that make platform adoption straightforward for other engineers.
  • Carry the platform on-call rotation and own production reliability for critical-path systems.

Requirements

  • 4+ years building production backend systems at scale.
  • Comfort with at least one systems language such as Go, Rust, or C++.
  • Comfort with at least one application language such as TypeScript or Python.
  • Hands-on experience designing and implementing an authentication or authorization service.
  • Experience building a token issuer, OIDC/OAuth2 provider, policy engine, permissions model, or FGA/ReBAC system such as Zanzibar, OpenFGA, SpiceDB, or Cedar.
  • Working knowledge of SAML, SCIM, OIDC, and OAuth2 at the protocol level.
  • Experience designing APIs and SDKs that other engineers depend on.
  • Experience operating distributed systems at scale, including caching strategies, consistency tradeoffs, and multi-region concerns.
  • Familiarity with identity vendors such as Auth0, WorkOS, or AWS/GCP/Azure IAM.
  • Strong production debugging instincts and a high bar for developer-friendly systems.
  • Preferred: experience building or contributing to a Zanzibar-style authorization system or running OpenFGA or SpiceDB in production.
  • Preferred: experience designing a multi-tenant permission model with custom roles, hierarchies, delegation, and ABAC attributes.
  • Preferred: experience shipping an SDK that product teams across an organization actually adopted.

Benefits

  • Competitive compensation with location-based premium market ranges in certain US markets.
  • Employer contributions toward healthcare.
  • Equity in the company through stock options for new team members.
  • Flexible time off in the US and generous time off in other countries.
  • $500 home office setup budget for remote employees.
  • Globally distributed, remote-friendly work environment across more than 20 countries.
  • Opportunities to connect with colleagues through company-wide global gatherings and offsites.
