Senior Platform Engineer

ABOUT TRUCKSMARTER Trucking moves 71% of freight in America, nearly $900 billion annually, yet the industry remains deeply fragmented and underserved by technology. TruckSmarter is fixing that, starting with the people at the center of it: truck drivers. We're a team of less than 25 building Dispatch, a vertically-integrated AI-powered product that performs many of the repetitive, time-intensive manual operations so that our users can focus on growing their business. The product is live, drivers are using it, and we're now focused on making Dispatch more powerful for the people who depend on it every day. THE ROLE We're looking for a Senior Platform Engineer to build and own the foundation that everything at TruckSmarter runs on. This is a high-ownership role on a team of fewer than 15 engineers where you'll architect core systems, drive developer velocity, and build infrastructure that supports both our product and our growing AI workloads. You'll work across the full infrastructure stack, from defining deployment pipelines and observability frameworks to leading security initiatives and mentoring engineers on reliability and performance. At our size, your decisions have immediate, visible impact on the product and the team.

We believe the best products get built when people are in the same room. Fast feedback loops, real collaboration, and a team that genuinely enjoys working together. If that's how you do your best work, you'll fit right in.   WE OFFER - Full health, dental and vision coverage - Daily catered lunch provided in-office, plus dinner covered for anyone working past 6:00pm - Commuter benefits - Flexible PTO - 401k - Commuter benefits   We would love for you to join us on this journey and are excited to review your application!
