Senior Software Engineer, Backend (Platform)

Built on over four decades of pioneering research at Princeton University, our platform represents the leading edge of innovation in freight and transportation planning. We help customers unlock double-digit revenue gains and drive smarter, data-driven operations at scale.
With the recent close of our Series C funding round led by Koch Disruptive Technologies, we’re entering an exciting new phase of growth. Today, Optimal Dynamics is a high-growth company of ~70 employees, backed by top-tier investors including Bessemer Venture Partners, The Westly Group, Activate Capital, and Koch. 

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

We are a team of bright, kind, and solution-oriented people focused on creating value for our customers. We can solve problems individually, but understand that the best solutions are found when the team brainstorms ideas together. 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.

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. 

Platform Engineering is the team our engineers build on. 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!
