Role Summary

We are seeking a Mechanical Engineer with strong experience in facility/transfer chambers setup and process module (CVD/MOCVD) design. You will lead the mechanical design and optimization of our MOCVD reactor chambers, working closely with process engineers and scientists to translate process requirements into process modules.

Key Responsibilities

• Design, model, and iterate on CVD/MOCVD chamber geometries using CAD tools (SolidWorks or equivalent)
• Designs components using variety of metals, ceramics, quartz, and advanced coatings for 2D material growth.
• Conduct detailed analysis including structural, element analysis, thermal, heat transfer, stress, vibrations, fluid and gas flow dynamics, and manufacturability to properly specify designs.
• Coordinate with vendors and machinists for prototyping and fabrication.
• Collaborate with process engineers to align chamber design with thin-film deposition uniform (WiW/WtW Nu%) and growth quality requirements.
• Develop and maintain engineering documentation, drawings, and BOMs.
• Support system integration and troubleshoot mechanical issues during installation and operation.

Qualifications

• B.S. or M.S. in Mechanical Engineering or related field
• 3+ years of experience in vacuum chamber or CVD/MOCVD system design
• Proficiency in 3D CAD (SolidWorks preferred) and FEA tools
• Familiarity with vacuum systems, high-temperature materials, and semiconductor processing environments
• Experience working with precision machining vendors and managing fabrication cycles
• Strong communication skills and ability to work in a fast-paced startup environment

Nice to have

• Experience with MOCVD or ALD systems
• Familiarity with 2D materials or thin film deposition processes
• Background in CFD-informed design for gas flow and thermal uniformity
