You’ll partner closely with You will work alongside the AI practice, whose work now sits inside several of our chains. and with the clients whose systems you’re building.

There’s no layer between you and the problem — the same person who scopes a system helps build and operate it. You will own Go services end to end, and Solidity where the chain carries contracts.

Success in the first year looks like [role-specific detail: e.g. a system taken from architecture to production, a client relationship you own technically, or a piece of infrastructure the rest of the team relies on]. If you like deep, long-term engineering with real consequences — not ticket churn — this is the shape of the work.
