Senior Software Engineer, Infrastructure

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.

• 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.

• 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 Type Script).
• Strong API and systems-integration experience.
• Comfort with on-call and production observability.

• Payments, settlement, or custody systems.
• ISO 20022 or Swift.
