Autonomous freight coordination. Backed by Y Combinator.
About the role
Build autonomous agents: Design and scale AI systems that can reliably automate complex, data-intensive workflows—handling everything from quoting to tracking—so customers can fully offload their logistics. Automate AI evaluation loops: Own the tooling to monitor, evaluate, and retrain AI models in production—ensuring performance improves automatically as new edge cases arise.
What they're looking for
- Builder at heart: You don’t just write code—you build products. You think in terms of customer impact, not just technical elegance. You take pride in shipping real things that solve real problems
- High-agency problem solver: You don’t wait for direction. You move fast through ambiguity, seek clarity on your own, and hop on the phone with customers to get to the root of issues and solve them directly
- Full-stack executor: You get handed a problem like “get this customer live,” and do whatever it takes—build the UI, extend the API, fine-tune the agent—to make it happen
- 3+ years of professional software development with a proven track record of building and scaling production systems
- YC startup background —you’ve thrived in fast-paced, zero-to-one environments where speed and ownership matter most
- Agentic applications —experience designing or building AI systems that act autonomously, adapt to context, and improve through feedback loops
More about this role
Cartage is building Wilson, an AI that coordinates freight for manufacturers and distributors—handling the tedious work of booking, tracking, and managing shipments end-to-end. Our customers range from lumber mills to furniture manufacturers.
With Wilson , teams can offload their entire logistics function and scale infinitely at a fraction of the cost of a human team.
Backed by Y Combinator (S24), Paul Graham, and a $3.3M seed round , we’ve hit an inflection point in revenue growth. We closed $200K ARR in 3 hours earlier this month and are scaling the team to meet accelerating demand.
This is a rare opportunity to build foundational systems that will define the future of how goods move. As a Full Stack Engineer , you’ll work side-by-side with the founders and take ownership of critical infrastructure, architecture, and AI design decisions from day one.
Cartage is a startup for builders who want full ownership. No PMs. No middle managers. Engineers own the customer experience end-to-end—from “what should we build?” to “it’s live and customers love it.”
Taste: Companies win on taste. Engineering is a creative discipline—part logic, part art—and we care deeply about how things feel,...
