Mechanical Engineer III

Beltways is building the world's fastest moving walkway.

Our proprietary transportation platform combines advanced mechanical engineering with intelligent software controls to create a next-generation passenger transportation system capable of operating up to 10x faster than traditional moving walkways. After successfully completing a public deployment and proving key performance benchmarks, we're entering an exciting phase of growth focused on commercialization, manufacturing scale-up, and future expansion.

We're looking for innovative engineers who are energized by solving complex problems and excited by the opportunity to help bring a first-of-its-kind technology to market.

We're seeking a Mechanical Engineer III to play a critical role in commercializing Beltways' breakthrough transportation technology.

This individual will help lead the transition from prototype to scalable production, driving mechanical design, manufacturing strategy, supplier collaboration, testing, and continuous product improvement. You'll work closely with software teams, manufacturing partners, and company founders to ensure our technology is innovative, reliable, and built for scale.

This is an opportunity to join a rapidly growing startup at a pivotal stage and help build the foundation of a future hardware engineering organization.
