About this role

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.

About AtoB

The trucking and logistics industry provides the backbone of the economy. But the payments infrastructure on which it runs is from the past century and broken. For the hard-working men and women of this sector, the existing suite of payment tools is outdated, difficult to use, prone to fraud, and saddled with shady fee structures. The incumbent players in this space often overlook the economic and practical needs of this user base.


We're changing that. AtoB is modernizing the payments infrastructure for trucking and logistics. Supply chains rely on the timely movement of capital to function efficiently. Our end game is a world in which that capital movement occurs reliably, instantly and fairly.


Our founding team has backgrounds in payments, working on electric and autonomous vehicles at Cruise Automation, leading ops and growth for Uber. We have senior engineers and operators from Google, Uber, Meta, Amazon, Shopify, Stripe, Revolut, Chime, Shell, McKinsey, BCG and other leading companies. We have raised $125 million+ from investors such as General Catalyst, Elad Gil, Bloomberg Beta, and Y Combinator, and have just recently been selected to join the World Economic Forum as a Global Innovator.
