Founding Full-Stack Engineer

THIS IS CURRENTLY AN EQUITY-ONLY POSITION. Salaries will be made available as cash constraints are resolved.

Credit is building a payment network and settlement ledger for a multi-asset world: pay in one currency, receive in another, settled in seconds. We have a working prototype and are moving into pilots. You’d be the first engineer I bring in alongside the founder.

What you’ll work on

The Rust ledger core: transaction processing, state and storage, validator consensus
Post-quantum signatures and encrypted networking
The APIs and services banks and payment companies will integrate with
The wallet app and web front end (Next.js and TypeScript): simple, clear screens to buy, send, exchange, withdraw and sell
Reliability, testing and security hardening before real money moves

What we’re looking for

Strong Rust, or strong systems experience in another language and real appetite to learn Rust
Comfortable building a clean, working front end in TypeScript. It doesn’t need to be a designer’s work, only simple and correct
Experience with distributed systems, databases or cryptography-adjacent code
You write tests, and you can read code you didn’t write
Comfort being first: no process, no manager, lots of ownership

Nice to have

Payments, fintech or banking-integration experience (ISO 20022, ACH, wires)
Consensus protocols or security audits

How this works

Contract role, paid in equity in Credit Inc. (being incorporated in Delaware) on a vesting schedule, with a move to cash and an employee role as funding allows
Remote, part-time to start
Short paid-in-equity trial first, then a longer agreement if it’s a fit
