Senior Software Engineer - Identity & Authorization Platform

Role Description

The Platform Auth team’s goal is to support our ‘one customer identity’ vision by providing tools, processes, and expertise for our engineering teams to create a unified access management experience while simplifying and standardizing engineering patterns in the space. We are looking for engineers to join our growing team!

• 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 decisions.
• 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.

Qualifications

• 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.
• 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 (Auth0, WorkOS, AWS/GCP/Azure IAM).
• Strong production debugging instincts and a high bar for systems that are easy to develop against.

Requirements

• Bonus: You've built or contributed to a Zanzibar-style authorization system, or run an OpenFGA or SpiceDB deployment beyond the demo.
• Bonus: You've designed a multi-tenant permission model that survived real customer requirements like custom roles, hierarchies, delegation, and ABAC attributes.
• Bonus: You've shipped an SDK that product teams across an org actually adopted, and have opinions about why most internal SDKs fail.

Benefits

• Flexible work environment - ClickHouse is a globally distributed company and remote-friendly.
• Healthcare - Employer contributions towards your healthcare.
• Equity in the company - Every new team member who joins our company receives stock options.
• Time off - Flexible time off in the US, generous entitlement in other countries.
• A $500 Home office setup if you’re a remote employee.
• Global Gatherings - Opportunities to engage with colleagues at company-wide offsites.
• Culture - As part of a rapidly scaling startup, you will be instrumental in shaping our culture.
