Our mission

The trucking and logistics industry provides the backbone of the economy. But the payments infrastructure on which it runs is 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 For the hard-working men and women of this sector, the existing suite of payment tools is outdated, difficult to use, prone to fraud, and saddled with shady fee structures.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 building Stripe for Transportation — 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 fairly, smoothly, and without delay. As we pursue that end game, we aim to center our customers in every way — offering them world-class customer experience and building products that work with and around the unique constraints of their daily lives. We build for fleet managers in the office and drivers on the road. We strive for products that are efficient, satisfying, and useful. Our customers enable our modern economy — they deserve it.


Our history and background

Our founding team has backgrounds in payments, working on autonomous vehicles at Cruise Automation, leading ops and growth for Uber, and building apps that were featured on the Apple app store. We have staff and senior engineers from Google, Uber, Meta, Shopify, Stripe, Chime, and other leading technology companies. 


We have raised $125 million+ from investors such as General Catalyst, Elad Gil, Bloomberg Beta, Y Combinator, XYZ; founders and CEOs of companies such as Google (Eric Schmidt), Salesforce (Marc Benioff), Coinbase (Brian Armstrong), DoorDash (Tony Xu), Instacart, Gusto; strategic investors like Mastercard, Flexport and Samsara.


We were named to Forbes annual Next Billion-Dollar Startup List, and have just recently been selected to join the World Economic Forum as a Global Innovator.

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.

Qualifications:

  • Have 5+ years of professional experience building B2B or B2C SaaS products (FinTech, payments, or marketplace a plus).

  • Prior payments or back office fintech experience is a plus

  • Thrive in zero-bureaucracy, high-ownership environments.

  • Balance speed with rigor—automated tests, clean abstractions, clear docs.

  • Can dive deep into code (we use React, Ruby, Postgres—but great engineers pick up tools fast).

  • Communicate crisply across time zones.

  • This role is required to be in office 4 days/week (Mon-Thurs) either in San Francisco Bay Area or Montreal
