Job description

Compensation: $120,000 - $180,000 / year

Department: Engineering

Location: Louisville, CO

Description

Stratom, Inc. is a mission‑driven engineering company building autonomous and unmanned off‑highway vehicles and related robotic systems. Our systems operate in demanding real‑world environments, where performance, reliability, and engineering discipline are essential. We integrate advanced autonomy with rugged industrial hardware for austere conditions.

Our work spans the full lifecycle of complex systems, from early concept and prototyping through fielded deployment. With multiple working prototypes in hand, we are transitioning these platforms into production to deliver capable systems at scale. We are looking for talented and experienced engineers who want to take ownership of hard problems and play a key role in bringing multiple platforms into production.

About the Role

This role is intended for a senior mechanical engineer comfortable operating across concept development, detailed design, hands‑on build, and production transition. You will work on rugged robotic and ground vehicle systems where mechanical design decisions directly impact system performance, reliability, manufacturability, and field supportability.

The successful candidate will take ownership of mechanical subsystems from early trade studies through prototype build, testing, refinement, and eventual production release. This includes designing components and assemblies, supporting fabrication and assembly, resolving integration issues, and collaborating closely with electrical, software, and systems engineers. As Stratom transitions multiple platforms from prototype to production, this role will shape designs that are functional, repeatable, supportable, and suitable for deployment at scale.
