We are hiring senior engineers for small teams building blockchain and AI systems where a mistake costs money. The same person is on the first call and the last one.
Fully remote · B2B, your own hours
The token layer of a cross-chain swap aggregator: a multi-season airdrop, a buy-and-burn, and the audit that has to come back clean.
Fully remote · B2B, full time
The services behind a cross-chain swap aggregator: quoting, execution, and the record that says what actually happened.
A small team of senior engineers, building systems where a mistake costs money. The way we work follows from that.
You own a part of the system from specification to production, and the decisions in it are yours.
Specifications, threat models and decision records come before code, so you never have to guess what is wanted.
Work when you work best. Few meetings, clear written briefs and answers that do not wait for a call.
Postmortems live in the repository and shape the next build, so the team gets sharper with every incident.
These apply to every role. Anything specific to a role is listed on its page.
Fully remote and async by default, with the team working around CET.
Every role shows the rate we actually pay. We do not negotiate down from a number we published.
A B2B contract in PLN or the USDC equivalent, with monthly invoices paid within seven days.
A company laptop and hardware security keys, provided and configured for you.
Short, written and the same for everyone.
Answer the questions on the role page. They tell us more than a CV does.
An engineer on the team reads every application, and we reply whether or not we take it further.
A call with the people you would work with, about work you have already done.
Scope, rate and start date, written down before you commit to anything.
Write anyway. We read every message, and we have opened a role for the right person before.
