Senior Software Engineer, Payments

We are looking for strong senior level candidates to join our Payments group as backend focused engineers.

Responsibilities:

Lead efforts to reconcile transactions across multiple financial providers, including Stripe, Highnote, Checkbook, and JPMorgan, ensuring accuracy and consistency across systems.

Ensure full alignment between internal records and customer-facing balances—what’s in the bank should precisely match what the customer sees.

Contribute to the development and ongoing scalability of our general ledger infrastructure, supporting accuracy, resilience, and growth.

Partner with our external ledger provider, Fragment, to build a reliable system capable of powering billions of transactions with speed and integrity.

Design and implement new money movement flows across a variety of payment rails—including push-to-card and wire transfers—optimizing for cost, speed, and reliability.

Own critical backend & platform projects end-to-end—from design to production ops.

Push architecture that scales to billions in annual payment volume and real-time risk controls.

Work closely with product and GTM leads to turn ambiguous problems into elegant code.
