Senior Platform Engineer

About TruckSmarter Trucking powers the American economy, moving 71% of the nation’s freight and representing nearly $900 billion in annual spend. Yet despite its scale, the industry still runs on fragmented systems, phone calls, emails, tribal knowledge, and manual coordination. TruckSmarter is changing that, starting with the people at the center of it all: truck drivers and small carriers. We’re a team of fewer than 25 building Dispatch, an AI-powered operating layer for freight. Think Claude Code for trucking. Dispatch helps carriers navigate a constantly changing freight market, reason through complex tradeoffs, and execute operational workflows on their behalf. The product is live, drivers are using it, and we’re now focused on making Dispatch dramatically smarter and more capable.
