Senior Mechanical Design Engineer

About the role

Northwood Space develops advanced ground station infrastructure to support global satellite communications. We are looking for a mechanical engineer to lead the development of antenna hardware, structural components, and production tooling. In this capacity, you will own the complete mechanical lifecycle of critical ground station systems, ensuring that theoretical designs translate into robust, scalable hardware solutions. You will be responsible for defining the physical architecture that allows our communication platforms to operate reliably in demanding environments. The role requires you to translate abstract mission requirements into precise mechanical specifications while balancing performance, cost, and manufacturability. You will act as a key integrator, ensuring that all mechanical elements align with the broader system architecture and operational goals. Your work will directly influence the reliability and efficiency of satellite communications infrastructure deployed globally.
