Senior Software Engineer - Cloud Partner Integrations

ClickHouse is a rapidly growing private cloud company recognized on the 2025 Forbes Cloud 100 list, specializing in real-time analytics and data warehousing. They are seeking a Senior Software Engineer for Cloud Partner Integrations to own the architecture and integration processes, ensuring seamless operation within customer environments.

Responsibilities:

• Owning the architecture: auth and identity flows, multi-tenancy, how data moves and where it's allowed to live, performance, and what happens in production
• Running what you build. You'll be on-call for your own work from early on, before there's a dedicated platform to lean on, which means owning the infrastructure, CI, deployment, and observability behind it
• Working on top of external platforms you can't change, and being straight about which risks are yours to manage and which aren't
• Partnering closely with the internal teams whose services you depend on: asking clearly, agreeing on interfaces, and finding ways to keep moving instead of waiting around to be unblocked

Requirements:

• 5+ years building software, with a good chunk of it on data-heavy or integration-flavored systems
• Solid backend and systems instincts. You can reason about deployment topology, multi-tenancy, and data movement, and you're comfortable owning architectural tradeoffs you'll have to live with later
• You've worked with modern auth protocols, service principals, and identity federation, and you know how to get it right across a trust boundary
• You've built on someone else's platform and know what that's actually like: incomplete docs, unintended breaking changes, etc
• You're comfortable in ambiguity. You can ship before the spec is finished, make sensible calls under uncertainty, and flag the decisions that'll be hard to undo instead of quietly baking them in
• You're good with other engineers. Much of the work runs through teams you don't own, and you earn their trust by how you think, not just what you commit
• You're mainly a backend engineer, but you're comfortable enough in JavaScript / TypeScript to jump in when it helps
• You use AI tools well and honestly. Reach for Claude Code, Cursor, Copilot, or whatever helps, and be clear about where you did and didn't
• You write well. Most of how we coordinate happens in design docs, PRs, and RFCs
• Familiarity with a major cloud data or analytics platform ecosystem
• Real depth in auth and identity federation, or experience shipping through a partner marketplace or certification process
• Experience designing multi-tenant SaaS platforms, or the isolation and deployment topology behind them
• Working knowledge of ClickHouse, or another columnar / OLAP engine
