Sr. Hardware Development Engineer

DESCRIPTION

As a Senior Hardware Development Engineer at Long Wall, you are the technical owner of complex hardware products that fly. You are versatile, working in the lab as often as at your desk, and own products ranging from fluid manifolds and tubing systems to primary structure and avionics enclosures. You take your products from concept through design, manufacturing, qualification, and field support, and you set the technical bar for the engineers around you. You collaborate closely with propulsion, avionics, GNC, manufacturing, and test teams to deliver integrated, flight-ready systems in a fast-moving, evolving-priorities environment.

• Drive design for manufacturability (DFM) and design for assembly (DFA), partnering closely with technicians, machinists, and suppliers to deliver hardware on cost and schedule
• Write and execute test procedures (component qualification, acceptance, integrated checkouts); analyze data and iterate designs based on results
• Author and present technical documentation—requirements, ICDs, design reviews, test plans, and reports—to internal and external stakeholders
