Weld Manufacturing Engineer

Job Description

Job Description

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.

About the Role

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.

The salary range listed for this role is intended as a general guideline. Final compensation will be determined based on a variety of factors, including role scope and responsibilities, relevant experience, education and training, key skills, market data, and business needs.

At Hermeus, compensation is only one part of our total rewards package. We offer competitive pay, equity, and a range of benefits designed to support our team.

• Health & Wellness: 100% employer-paid healthcare and pet insurance
• Financial: Competitive pay, stock options, 401(k) retirement plan, and potential year-end bonuses
• Time Off: Paid parental leave, 12 federal holidays, unlimited PTO for exempt employees, and generous accrued PTO for non-exempt employees
• Office Perks: Weekly paid office lunches and fully stocked breakrooms
