Senior / Staff Mechanical Engineer, Fluid Systems

The role

You will own the design, analysis, and validation of subsystems for thermal batteries. You will work across disciplines to scope, design, and refine mechanical systems from concept through prototyping, testing, and production.

What you will do

• Lead architecture, analysis, detailed design, and testing of structural, thermal, and fluid components
• Apply calculations, finite element analysis (FEA), and trade studies to guide design decisions
• Lead prototyping, testing, failure analysis, and root cause investigation
• Identify and implement design and manufacturing approaches to reduce cost
• Define system requirements, lead design reviews, and integrate feedback across teams
• Develop and maintain CAD standards, documentation, and engineering infrastructure
• Guide junior engineers and serve as a technical lead
• Balance fast execution with long-term improvements in team workflows and product development culture

Required qualifications

• Senior Engineer: Bachelor’s degree in Mechanical Engineering with 6+ years of relevant industry experience, or Master’s degree with 4+ years, or PhD
• Staff Engineer: Bachelor’s degree in Mechanical Engineering with 10+ years of relevant industry experience, or Master’s degree with 8+ years, or PhD with 4+ years
• Relevant industry experience includes power generation, aerospace, propulsion, or other industrial hardware products
• Proven track record of taking complex mechanical systems from concept to deployed hardware
• Strong proficiency with CAD (SolidWorks or similar), PDM systems, and creation of detailed drawings using GD&T and ASME Y14.5
• Deep experience designing machined components for low- to mid-volume production
• Proficiency in structural and/or thermal analysis, including FEA and hand calculations
• Experience applying sound engineering judgment in ambiguous, first-of-a-kind environments
• Curiosity about integrating evolving AI tools into engineering workflows
• Familiarity with systems analysis and risk management tools such as FMEA
• Experience developing engineering processes, standards, and best practices
• Excellent written and verbal communication skills

Nice to have

• experience with sheet metal, castings, or composites
• Experience designing components for very high-temperature environments ( 500–2500°C )
• Experience with composite and/or brittle materials
• Experience with fluid system design in demanding thermal or industrial environments
• FOAK (first-of-a-kind) product development from concept through sustaining

Benefits

• equity compensation in the form of stock options
• premium health benefits package with life and disability insurance
• 401K plan with employer contributions
• flexible spending accounts
• industry leading paid-time-off policy that features flexible and inclusive holiday observance
