What we ship

Very real workloads.

Core engine

The database itself

Columnar storage, vectorized SQL, open data lakehouse, Horizon joins, streaming materialized views. Written in low-latency Java (zero-GC), Rust, C++, and assembly.

Cloud & BYOC

The system around it

Kubernetes operators, multi-region replication, live migrations, the control plane that runs QuestDB inside a customer's own AWS or Azure account without them losing sleep.

Ready for agents

Built for the agentic stack

Native REST API, low-latency SQL, and open formats AI agents can read directly. As more queries come from autonomous systems, the database has to answer in milliseconds and expose its schema cleanly to any agent framework or autonomous workflow.

Performance

The thing we're known for

JIT codegen, SIMD hot loops, memory layout experiments. If shaving 220µs off a query makes you excited, read on.

How we work

Things we actually mean

Remote, with anchors in London and NYC

The team works remote by default, with local offices in London and New York for anyone who wants a desk, a whiteboard, or a drink after work.

Open source is not a side quest

Our core is Apache 2.0, PRs get reviewed in public, and the community sees the same code our enterprise customers run.

Everyone talks to users

No account-manager firewall. Whatever your role, the people running our database in production are one Slack message away.

Stay open, delete proprietary

We'd rather lose an RFP than bolt on a closed-source dependency that traps the user.

Benefits

The boring stuff, done well

Equity in a company that ships

Meaningful options on transparent bands, so you benefit when the database does.

Remote, with regional hubs

Most of the team is remote; we also have offices in London and New York and are actively hiring into both.

Annual team offsite

One week, one room, the whole team. Past stops: Malta, Scotland, English countryside, London, NYC.

Open roles

We're hiring. Tell us what you'd build.

Don't see your role?

We hire for impact more than headcount plans. If you can make the product, the company, or the community measurably better, we want to hear from you.
