Senior Mechanical Design Engineer (Seattle)

  • Craft Recruiting
  • Seattle, Washington
  • Full Time

We are partnered with an innovative cleantech company at the forefront of hydrogen generation and carbon removal. They are looking for a Senior Mechanical Design Engineer to design, develop, and iterate on advanced reactor systems and critical mechanical assemblies that power their transformative technology. This role spans concept development, high-performance design, prototyping, and buildout within a highly collaborative engineering environment.

Why Join:

  • Revolutionary Impact: Work on a Client hydrogen generation technology poised to transform the energy sector and combat climate change.
  • Career Growth: Lead mechanical designs from concept to production, mentor early-career engineers, and collaborate with experts across disciplines.
  • Comprehensive Benefits: Competitive compensation, stock options, and relocation assistance for top talent.

What You'll Be Doing:

  • Own the mechanical design of reactor components, including vessels, flanges, welded structures, frames, and articulated mechanisms.
  • Lead CAD modeling, detailed drawing creation, and documentation for complex mechanical assemblies.
  • Perform stress and thermal analysis using hand calculations and FEA (ANSYS Workbench preferred).
  • Contribute to structural and sealing design for high-temperature environments.
  • Develop and iterate designs based on test stand performance and experimental data.
  • Specify tolerances and GD&T; execute tolerance stack-up analysis.
  • Collaborate cross-functionally with thermal, combustion, transfer, and controls engineers.
  • Support prototype fabrication, test setup, and early-stage design validation.
  • Mentor junior engineers and coordinate design reviews.

What You Bring:

  • Bachelor's degree in Mechanical Engineering or related field.
  • 10+ years of experience in mechanical design engineering within industrial or high-performance environments.
  • Hands-on experience designing welded structures, skids, and articulated mechanisms.
  • Proficiency with 3D CAD (SolidWorks preferred) and experience creating production-ready drawings.
  • Strong experience with thermal-mechanical FEA (thermal, structural).
  • Strong communicator and collaborator on multidisciplinary teams.

We'd be Really Excited If You Had Some of These:

  • Experience with high-temperature design (400-1200C) and materials selection for such environments
  • Structural FEA background with aerospace, turbine, or similar experience
  • Experience designing sealing systems, flanges, pressure vessels
  • Background in hydrogen systems, containerized energy systems, or industrial equipment in harsh environments

What's in It for You:

  • Competitive Salary: $120,000 - $160,000/year
  • Equity: Stock options for company ownership.
  • Comprehensive Benefits: Full healthcare coverage, retirement matching, and relocation support.
  • Work-Life Balance: Unlimited PTO, flexible schedules, and a collaborative, dog-friendly office.
  • Professional Development: Annual budget for continued education and growth opportunities.
