Full Job Description

About the Team We are seeking a highly capable Mechanical Engineer to design and develop electrical interconnect systems for next-generation UAV platforms. This role focuses on wire harness architecture, connector integration, and packaging of electrical subsystems within tightly constrained vehicle structures. Emphasis is placed on reliability, efficient routing, thermal performance, and minimizing size and mass while maintaining durability in operational environments. About the Role The position operates in a fast-paced, prototype-driven engineering environment with strong emphasis on hands-on development. We provide access to electrical labs, harness fabrication tools, additive manufacturing, and in-house test capability to enable rapid concept-to-hardware iteration. The role offers autonomy, cross-functional collaboration, and ownership of critical interconnect subsystems from early architecture through validation.
