About the teamMost providers make customers migrate their data to them. We're doing the opposite: bringing ClickHouse Cloud into the environments our customers already trust, so their data stays useful right where it lives.Some are major cloud data platforms that run ClickHouse as a native service, so customers get it without leaving the tool they already use. Some are BI and visualization tools that need ClickHouse to show up as a fast, first-class data source behind their dashboards.

And some are developer and data platforms we connect through marketplaces and identity federation with a couple of clicks to link an account. As the founding backend engineer, you'll set the technical defaults for this team. You'll have end-to-end ownership, but you'll also work inside the constraints of platforms you don't own: thin documentation, unfamiliar deployment topologies, and timelines governed by partner approval cycles.

A lot of the challenge is engineering across trust boundaries you don't fully control. You won't be doing it alone. You'll work closely with the team's engineering manager and a small founding group that will grow around you, but you'll be the one setting the technical direction.

What you'll doYou'll own an integration end to end: the design, the code, and the production system that keeps running after launch.

Owning the architecture: auth and identity flows, multi-tenancy, how data moves and where it's allowed to live, performance, and what happens in productionRunning 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 itWorking on top of external platforms you can't change, and being straight about which risks are yours to manage and which aren'tPartnering 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 unblockedWe'd also expect you to have opinions about where this should go, and to write them down. About youYou don't need to have experience of every single point, but these are the attributes of someone who will perform well in this role:5+ years building software, with a good chunk of it on data-heavy or integration-flavored systemsSolid 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 laterYou've worked with modern auth protocols, service principals, and identity federation, and you know how to get it right across a trust boundaryYou've built on someone else's platform and know what that's actually like: incomplete docs, unintended breaking changes, etc.You're mainly a backend engineer, but you're comfortable enough in JavaScript / TypeScript to jump in when it helpsYou use AI tools well and honestly.
