About the role

  • You'll work with frontend, mobile, product, and our Forward Deployed Engineers, and you'll have meaningful input on how the system should behave for scalability and performance.
  • Our code has been ~100% AI-generated since March 2026.
  • We expect the engineering team to be spinning up agents and managing the output rather than writing code by hand.

Responsibilities

  • Manage state machines across projects, orders, jobs, and loads.
  • Design geofencing and geo-driven event processing that turns raw GPS into structured dispatch events.
  • Build algorithmic dispatch and optimization, including automated load assignment.
  • Build integrations with telematics providers, scale houses, ERPs, and other external systems.
  • We're a Series A company backed by Mucker Capital, and we're building the team that will take us from $XM to $XXM+ ARR.

Requirements

  • Strong Rails experience, or strong experience in a comparable backend framework and willingness to ramp fast.
  • You can model workflows where the source of truth is unreliable and the system still has to settle correctly.
  • You can debug production issues and explain root causes.

Skills

  • devcontainers, fast feedback, pre-approved permissions, cloud agent support.
  • Improving the SDLC is first-class engineering work.
  • Before You Apply
  • Write only CRUD endpoints.
  • Work from fully-specified requirements.
  • Treat AI coding tools as a side experiment.
