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! 

What you will be doing:

• 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.

What you bring along:

• 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.

Bonus:

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

About the team

The Integrations Ecosystem org is the bridge between ClickHouse and the rest of the data world. We build and maintain the connections that make ClickHouse accessible to the developers, data engineers, and analysts who rely on it in production every day. Our scope spans low-level database drivers, ingestion and CDC pipelines, data framework integrations, and BI connectivity — ensuring ClickHouse feels native in whatever stack our users already have.

We maintain the official language clients (Python, JavaScript, Java, Go, Rust, C++, C#) and ODBC driver; ship first-party connectors for Kafka Connect, Apache Spark, Apache Flink, dbt, and Airbyte; and own integrations with BI platforms.

This role sits on the Language Clients team, which provides the JVM foundation that everything else in the ecosystem is built on.

What you'll do

As a Senior Software Engineer on Language Clients, you'll be a technical owner of ClickHouse's Java client and JDBC driver, the foundation that our own Connectors team and a long list of external 

frameworks rely on to talk to ClickHouse.

Your primary users are engineers: the Connectors team building ClickHouse connectors for Kafka, Flink, Spark, and others, and the broader JVM ecosystem (data ingestion tools, BI platforms, data visualizations) that consumes the driver directly. Your job is to make sure they have a fast, reliable, well-designed foundation  and to treat their feedback as the signal for where the driver goes next.

In your first year you can expect to:

• Own the Java client and JDBC driver end-to-end: roadmap, API design, performance, release engineering, and partner-facing support.
• Drive throughput and latency work across the client and ClickHouse server
• Partner day-to-day with the Connectors team as an embedded internal customer: understand what their connectors need from the driver, and ship it.
• Engage directly with external partners across data ingestion, and data visualization on interoperability, regressions, and roadmap alignment.
• Ship visible, measurable wins in throughput, stability, and developer experience.

We expect you to bring opinions, artifacts, and written proposals to shape where we invest next.

About you

• 5+ years of software engineering experience with a significant portion focused on data-intensive systems: drivers, SDKs, ingestion, CDC, streaming, or analytics.
• Deep Java and JVM expertise: memory model, GC tuning, profiling, and the ability to reason about throughput and latency at the level of bytes on the wire.
• Hands-on experience building or substantially extending a library that other engineers depend on. You understand that API design compounds, and that a breaking change in a widely used library is a very different thing from a breaking change in an application.
• Strong grasp of database fundamentals: SQL, query execution, and analytical/OLAP workloads. Judgment about when to lean on framework abstractions versus when to drop down to the protocol.
• Solid instincts on concurrency in the JVM: executors, reactive streams, backpressure, connection pooling, and the failure modes that come with each.
• Thoughtful, transparent use of modern AI development tools (Claude Code, Cursor, Copilot, or equivalents) combined with strong independent design and code review judgment. We expect engineers to lean on AI where it's genuinely helpful and to be explicit about where they didn't. Resistance to AI tooling is a mismatch for this team and so is over-reliance without the underlying engineering depth to review what comes out.
• Excellent written communication. Most of our coordination happens in design docs, PR descriptions, and RFCs.
• Genuine open-source disposition: comfort engaging with community issues, external contributors, and public design discussions. You don't need to be a maintainer of a well-known project, but you do need to be comfortable working in the open.

Nice to have

• Working knowledge of JDBC internals, ADBC, or Arrow / Arrow Flight SQL.
• Experience designing or evolving wire protocols, or contributing to a widely-used network client.
• Prior contributions to open-source data infrastructure (Kafka, Spark, Flink, dbt, Debezium, Iceberg, or similar).
• Working knowledge of ClickHouse or another columnar/OLAP engine.

• Solid experience in designing and building applications with React and TypeScript
• Experience writing and maintaining automated tests (unit, integration, and E2E) as part of a CI/CD workflow
• Practical knowledge of backend systems, REST and/or GraphQL APIs, and service-oriented architecture
• Great communication skills and the ability to work effectively in a distributed, async-friendly team

Nice to have:

• Familiarity with Go, Node, or other server-side languages
• Familiarity with cloud infrastructure concepts and infrastructure-as-code tools such as Terraform
• Experience working on data-intensive products or platforms at scale

Why Join Us:

• Opportunity to work with cutting-edge technology at the intersection of data engineering and cloud-native infrastructure.
• Be part of a high-visibility team integral to the company’s success.
• Operate with autonomy, ownership, and the ability to drive meaningful impact in a rapidly evolving space.
