Weld Manufacturing Engineer

Hermeus is a venture-backed defense aviation company reclaiming the lost art of rapid iterative prototyping to build the fastest aircraft in the world today. By prioritizing relentless hardware iteration, we deliver high-speed systems at the pace of the modern battlefield. We work with the Department of War to provide the high-speed capabilities our nation and its allies need to maintain a durable, asymmetric advantage.

 

As a Welding Manufacturing Engineer, you will play a critical role in enabling rapid development, fabrication, and integration of advanced hardware across our R&D and prototype manufacturing environments. You’ll be responsible for developing weld processes, fixtures, and joint designs that bridge early design concepts to flight-ready hardware. This position is hands-on and deeply cross-functional, working directly with design, manufacturing, and test teams to bring complex systems from concept to reality.

• Develop, qualify, and optimize weld processes and parameters for multiple techniques including, but not limited to, electron beam, laser beam, gas tungsten arc, gas metal arc, plasma arc, resistance, friction-stir, and orbital tube welding.
• Support R&D and production builds of welded aircraft structures, tanks, and propulsion assemblies, providing direct guidance to technicians and manufacturing engineers.
• Collaborate with design and manufacturing engineering to drive weld joint design, fixture development, and assembly methods optimized for manufacturability, precision, and repeatability.
• Lead root cause investigations related to weld performance, material compatibility, and process deviations; implement corrective actions based on metallurgical and mechanical findings.
• Plan and execute weld qualification campaigns, including mechanical testing, NDE inspection, and data interpretation.
• Partner with NDE specialists to evaluate weld quality and develop advanced inspection techniques tailored for high-performance aircraft applications.
• Implement process control improvements using feedback from weld tests, NDE, and production data to increase reliability and consistency.
• Identify and integrate automated or robotic welding solutions to improve throughput, consistency, and quality.
• Research and evaluate emerging welding technologies and materials for potential application in hypersonic vehicle manufacturing.
• Collaborate closely with tooling, automation, and integration teams to develop solutions that minimize distortion, improve accuracy, and accelerate production timelines.

• Bachelor’s degree in mechanical engineering or other related technical discipline.
• Hands-on fabrication, manufacturing, or testing experience with structural aerospace assemblies.
• Ability to thrive in a fast-paced environment, the person in this role is primarily focused on execution.

• Degree in Welding Engineering or related technical field.
• Hands-on welding experience with nickel-based alloys, stainless steel, titanium, copper, and aluminum.
• Understanding of weld design principles and mechanical tolerances under thermal and structural loads.
• Experience with brazing, joining, and metallographic interpretation.
• Understanding of welding processes including, but not limited to, electron beam, laser beam, plasma arc, resistance, friction-stir, gas tungsten arc, and gas metal arc.

• Prolonged periods of sitting at a desk and working on a computer.
• Frequent walking through office, manufacturing, and test facility environments.
