## About the role

As an AI backend engineer, you will work closely with founders and customers to understand and solve their logistics billing and payment pain points. You will ship features that directly impact customers, and you will do it with AI in two ways: building products with AI, and building the systems that let AI agents and non-technical users deliver technical work that used to require an engineer. The most valuable work here solves a whole category of problems rather than a single one-off feature.

## What they're looking for

- Work cross-functionally with product, design, and sales to understand requirements and ship thoughtful solutions
- Build and ship the AI harness: the data pipelines, schemas, validation, and feedback loops that let agents do work reliably at scale
- Start from the outcome, not the process: curate the harness, data, and success criteria instead of the specific logic, then let agents write and validate it against real data
- Write high-quality code optimized for extensibility, working across component boundaries from frontend to backend, infrastructure, and our AI stack
- Engage in code reviews to maintain a high bar of engineering excellence
- Lead discussions and documentation to communicate and arrive at the best technical design
