Founding Engineer at Riverbend

Payments infrastructure for small banks. Ship the V1 ledger, own the stack, hire the team.

The company in one paragraph

Riverbend is building the payments stack that community banks can't build themselves. The big three core providers (FIS, Fiserv, Jack Henry) charge mid-five-figures a month for ledgers that haven't changed architecture since 2004. There are 4,100 community banks in the US. We replace the ledger and the money-movement layer with a modern API, and we let the bank keep its charter, its compliance posture, and its customer relationships.

We closed a $6.2M seed in January led by Greylock. First two design partners signed. We need one more engineer to ship the V1 production ledger by September.

What you'll actually do

• Own the ledger. Double-entry, immutable, audit-ready, eventually-consistent across regions. Probably Rust or Go on Postgres. You pick, you defend it.
• Integrate the rails. Fedwire, ACH, RTP, and card networks. We have a compliance partner lined up; you write the code that talks to them.
• Set the engineering culture. We're going from two engineers to seven this year. You help us hire the next five.

Who this is right for

You've shipped a system that handles money in production. You know what "reconciliation" means without having to look it up. You want to be the second or third engineer at something that's trying to become real infrastructure, not the fortieth engineer at something that's trying to become a unicorn.

You don't need to have worked at a bank. You do need to have written code that other people's livelihoods depend on.

What we offer

• $190K base, 1.5% equity, 10-year exercise window.
• Full healthcare, dental, vision. 401(k) match up to 4%.
• Remote-first. Two co-located weeks per quarter (NYC or SF, company-paid).
• A small team (you'd be employee #4) that has shipped together before.
