Founding Backend 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
• 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
• 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 a larger role as funding allows
• Remote, part-time to start
• Short paid-in-equity trial first, then a longer agreement if it's a fit
