Systems, not screens
Order execution, financial reconciliation, permission-aware retrieval, multi-tenant AI. The work is mostly about correctness under conditions you cannot fully control.
CAREERS
Work on systems
that have to hold.
We are a small senior team building AI, data, cloud and product systems for clients where failure carries real operational, financial or regulatory cost.
There are no open roles listed today. We still read everything sent to hr@cosmoxyn.com.
01 / THE WORK
What you would
actually build.
Client work, in production, with the constraints that come with it.
Close to the client
Engineers talk to the people they build for. No account manager relays the requirement, and no one hands you a spec you had no part in shaping.
AI-native, in practice
We use AI throughout our own engineering. That is a working method here, not a line in a deck.
02 / WHAT WE LOOK FOR
Judgement,
not just output.
- You have shipped something that stayed up, and can explain what it took.
- You reach for the boring, correct solution before the clever one.
- You can say when a requirement is wrong — to us, and to a client.
- You write clearly. Most engineering disagreements are resolved in prose.
HOW TO APPLY
Tell us what
you have built.
We do not run a pipeline of open requisitions. When the work needs another engineer, we start with the people who have already told us who they are.
