Senior Software Engineer, Infrastructure
New York · Remote (US) · Full-time
Build the connective layer: the systems that let institutions reach external networks from the infrastructure they already run, with correctness and auditability as first-order requirements.
What you'll do
- Design and build backend services for connectivity and settlement.
- Integrate with bank core, custody, and ledger systems and the external networks institutions choose.
- Build reconciliation and audit-trail tooling that holds up to examination.
- Own reliability and observability for the systems you ship.
- Work with compliance to keep controls in the transaction path, not bolted to the side.
What we're looking for
- 5+ years in backend or distributed systems.
- A correctness-first mindset from a high-reliability domain (payments, settlement, trading, or similar).
- Fluency in a modern typed language (Go, Rust, or TypeScript).
- Strong API and systems-integration experience.
- Comfort with on-call and production observability.
Nice to have
- Payments, settlement, or custody systems.
- Crypto infrastructure.
- ISO 20022 or Swift.
