Welding Manufacturing Engineer

Los AngelesOn-siteFull-time

AI Summary

Welding Manufacturing Engineer focuses on developing weld processes, fixtures, and joint designs to enable rapid fabrication and integration of advanced hardware for R&D and prototype manufacturing.

About this role

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.

Responsibilities

  • 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.

    • Basic Qualifications

  • Bachelor’s degree in Mechanical Engineering or other related technical discipline.
  • Hands-on fabrication, manufacturing, or testing experience with welded aerospace assemblies.
  • Strong understanding of weld design principles and mechanical tolerances under thermal and structural loads.

    • Preferred Skills and Experience

  • Master’s degree in Welding Engineering or related technical field.
  • Hands-on welding experience with nickel-based alloys, stainless steel, titanium, copper, and aluminum.
  • Experience with brazing, joining, and metallographic interpretation.
  • Deep 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.
  • Robot programming experience for automated welding applications.
  • Tooling design experience for welded assemblies to minimize distortion and improve repeatability.
  • Knowledge of weld strength testing methodologies, standards, and data acquisition systems (ASTM E8, E399, E740, ISO 15653, AWS D17.X, AWS C7.X, thermocouples, strain gages, etc.).
  • Experience performing root cause analysis and corrective actions using techniques such as optical and SEM fractography, hardness testing, chemical analysis, and mechanical testing.
  • Demonstrated success applying Design for Manufacturability (DFM) principles to transition welded designs from prototype to production.
  • Strong ability to multi-task, prioritize, and communicate results across engineering, manufacturing, and leadership teams.
  • Highly detail-oriented with excellent documentation and organizational skills.
  • Proven track record of success in fast-paced, high-growth, technically demanding environments.

    • Additional Requirements

  • Must be willing to work extended hours and weekends as needed to support build schedules and testing operations.
  • Occasional travel may be required to support suppliers or test campaigns.
  • Ability to perform hands-on work in fabrication and prototype build environments, including climbing, lifting, and working in confined areas as required.
  • Desire to be part of a high-intensity, mission-focused team driving innovation in hypersonic aircraft development.
