Mechanical Engineer

• As a Mechanical Engineer, you will play a critical role in the design, analysis, build, and operation of laser, pulsed power, vacuum vessel, and ancillary mechanical systems that are central to Xcimer’s excimer‑laser‑based IFE technology
• . You will contribute across the full product lifecycle—from early prototype systems through the design and demonstration of a power‑producing inertial fusion reactor. We are seeking engineers who bring strong technical depth, hands‑on problem-solving skills, and a passion for building high‑performance hardware that will redefine the future of energy
• Create 3D models, detail part drawings, assemblies, P&ID’s and interface control documents
• Design structures and pressure vessels, perform proof-tests to code standards
• Communicate and document design with mechanical, systems, laser and optical engineering and manufacturing team members
• Support procurement of the hardware for the prototype laser amplifiers and optical conditioning equipment
• Selection of sensors and instruments, work with controls team for integration
• Oversee and assist assembly by a team of interdisciplinary technicians
• Support ongoing operation of the subject equipment and systems
• Continue above roles and responsibilities to participate in subsequent amplifier up-scaling leading to that which is needed for a power-producing IFE reactor
• Participate in concept studies supporting the use of these lasers in a power-producing IFE reactor, and other applications
• Contribute to authoring work instructions, test plans, specifications, and other documentation for the integration and operation of complex systems of systems
• Provide manufacturing and production support and first-time engineering builds
• Participate in design reviews and help to streamline engineering processes
• Work with cross-functional teams that are responsible for selecting materials, manufacturing processes, and suppliers to produce world class hardware
• Plan, coordinate, conduct tests, and review test data
• Maintain and report on activity schedule, budget and technical status
• Identify opportunities for improvements and operational cost savings
