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 For the hard-working men and women of this sector, the existing suite of payment tools is outdated, difficult to use, prone to fraud, and saddled with shady fee structures.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.

About Us


Learn more about our mission, culture, and background on our Careers Page.

Responsibilities:

  • Scope and lead large, often ambiguous technical projects, laying the groundwork for early-stage products to iteratively evolve and scale.

  • Design, build, and maintain APIs, user-facing experiences, services, and systems.

  • Make effective tradeoffs between business priorities, user experience, and reliability.

  • Own critical frontend, 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.

  • Mentor a squad of 3-4 strong engineers; raise the bar on code quality and velocity.

Qualifications:

  • Have 8+ years of professional experience building B2B or B2C SaaS products (FinTech, payments, or marketplace a plus).

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

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

  • Can lead architecture discussions and still 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, New York, Los Angeles, Montreal, Vancouver, Toronto

What you need to know about the Calgary Tech Scene

Employees can spend up to one-third of their life at work, so choosing the right company is crucial, not just for the job itself but for the company culture as well. While startups often offer dynamic culture and growth opportunities, large corporations provide benefits like career development and networking, especially appealing to recent graduates. Fortunately, Calgary stands out as a hub for both, recognized as one of Startup Genome's Top 100 Emerging Ecosystems, while also playing host to a number of multinational enterprises. In Calgary, job seekers can find a wide range of opportunities.
