Job description

We are seeking a highly motivated engineer to support the design, development, integration, and fielding of a next-generation autonomous aircraft system. This position requires a balance of technical rigor, rapid decision-making, and hands-on engineering to efficiently transition concepts into operational capability. The ideal candidate is comfortable solving complex problems, taking ownership, working within an accelerated aircraft development environment, and is motivated by getting meaningful capability into the hands of operators quickly.

• Design complex electro-mechanical solutions for avionics packaging, electrical interconnects, thermal management, and aircraft integration
• Perform structural, preliminary thermal, and modal analyses for avionics to ensure survivability in harsh environments
• Ensure avionics meet performance, safety, environmental, and EMI/EMC compliance standards, including DO-160, DO-254, DO-178C, MIL-STD-810, and MIL-STD-461
• Own your design work from concept to reviews through system validation, failure analysis, and flight test readiness.
• B.S. and/or MS in Mechanical/Aerospace Engineering
• 10+ years of experience in mechanical & electrical equipment design for aerospace, including harness integration and mechanical component design
• Expertise in CAD software (NX, SolidWorks, CATIA, or similar) for 3D modeling, drawing creation, and system layout.
• Familiarity with eCAD software (Altium, Cadence, Allegro), and harness design software (Capital, Zuken)
• Experience working with electrical engineers to define PCB constraints, develop circuit cards, and care for all themechanical interfaces
• Familiarity with the PCB layout process and advanced manufacturing methods
• Experience with finite element analysis (FEA), thermal analysis, and fatigue/lifecycle testing
• Ability to work in a fast-paced, agile development environment with evolving priorities
