We're on a mission to redefine the way logistics decisions are made—and we’re just getting started.

About Our Team

We are a team of bright, kind, and solution-oriented people focused on creating value for our customers.

We are excited about balancing the need to deploy new solutions quickly and designing solutions that are secured, reliable, maintainable, and scalable for the long run.

Role Overview

We're looking for a talented Senior or Staff-level Backend Software Engineer to join our Platform Engineering team and help build the foundation that powers intelligent transportation logistics technology.

You'll own the systems, services, and tooling that let product teams ship quickly and safely — and you'll contribute directly to key customer-facing projects where platform capabilities are the product. This is a role with leverage: your work multiplies across every team and every customer deployment. The role spans internal tool Development, Infrastructure, and Security, ensuring that our engineering team can build, deploy, & operate systems with speed, safety, & confidence.

In this role, you’ll help define best practices, guide cross-functional initiatives, & design systems that scale with our rapidly growing platform. You’ll partner closely across engineering & product teams, balancing reliability & velocity while mentoring others & raising the overall technical bar. You’ll work with Python, Django, AWS, and Terraform to design and scale the backend and infrastructure behind our platform. You’ll influence technical direction, architectural standards, and how our engineering organization operates as it grows.

This is a full-time, remote-friendly position open to candidates across the United States. For those who prefer an in-person experience, our New York City headquarters offers a collaborative office environment. Ready to make an impact? Join us and help redefine the logistics industry!
