Senior Backend Developer

Senior Backend Developer - Real-Time Fleet Routing (GPS + Maps)

About us

We run an outsourced dispatch company for tow truck fleets in the United States, with our dispatch team based in Serbia. Our dispatchers move hundreds of tow trucks every day across Illinois. Now we’re building our own routing system, Routing Brain, and later we’ll sell it to tow companies across the US.

What you’ll build

You’ll be the one developer who builds and owns Routing Brain from day one to go-live on a 150-truck fleet:

• GPS tracking for 150 trucks with Teltonika trackers and Traccar;
• A live dispatch console (React) showing every truck on a map in real time;
• A routing engine that picks the best truck for every call using live traffic (Google Routes API), truck type and driver shift, and refreshes ETAs every 15 minutes;
• Daily route plans per truck with Google OR-Tools;
• A phone web app for 200 drivers: login, job status, navigation;
• One integration with our towing software.

A clickable mockup, a full scope document and a budget are ready. You won’t start from a blank page.

How we work

• You use AI coding tools (Claude Code or similar) every day. We expect it, and it’s how the project is planned and budgeted.
• You own the code: architecture, security, deployment and fixing production problems.
• Short daily written updates and a weekly demo with the founder.
• Overlap with Chicago mornings: 15:00–19:00 Belgrade time.

You have

• 5+ years of backend development (Python or TypeScript/Node);
• Built and run at least one real-time system in production: GPS/IoT, logistics, delivery, ride-hailing or similar;
• PostgreSQL, ideally with PostGIS;
• WebSockets or other live-update tech;
• Worked with map or routing APIs (Google Maps, Mapbox, OSRM);
• Deployed and monitored your own services on AWS, GCP or similar;
• Real experience with AI coding tools, and judgment about when not to trust them;
• Good written English.

Nice to have

• Traccar or Teltonika devices;
• Route optimization (OR-Tools, VROOM) or vehicle routing problems;
• React front end;
• Fleet, trucking or towing industry background.

What we offer

• Competitive salary;
• A real product from zero, with direct access to the founder and the dispatchers who use it every day;
• You’d own the product end to end and build it with AI coding tools. Remote from Serbia, about 560 hours for ~14 weeks, then ongoing as we turn Routing Brain into a product for US tow companies.
