Mechanical Engineer

We are looking for a highly skilled Mechanical Design Engineer to join our team. This role

supports the design and development of high-temperature heating elements, storage

media, and insulation layers at the very core of the Heat Battery. The ideal candidate

combines strong mechanical design and thermomechanical experience with hands-on

experience with integrated hardware involving refractories and other high temperature

materials.

• Support the mechanical design and validation of components, assemblies, and
• systems subjected to repeated thermal cycling and operating temperatures up to
• Develop high-temperature and high-power systems and assemblies using metals,
• ceramics, refractories, and other appropriate materials.
• Design and validate mechanical interfaces, compliant mechanical features, and
• sealing solutions that accommodate differential thermal expansion while
• maintaining structural integrity and environmental isolation
• Perform CFD and 1D heat- and mass-flow analyses to identify design-driving factors
• and inform system-level decisions.
• Conduct FEA to evaluate and validate mechanical and thermomechanical
• performance.
• Contribute to and lead design and process FMEA activities.
• Develop component-level test methodologies and design experiments to validate
• performance and reduce technical risk.
• Use CAD and PLM software—Solid Works preferred—for design, documentation,
• and configuration control.
• Develop and define system functions, testable design requirements, and interfaces
• with other subsystems in a systems engineering context
• Prepare technical documentation for external suppliers and internal stakeholders.
• Collaborate with manufacturing and supply chain teams to improve designs for
• manufacturability and assembly, establish process controls, perform First Article
• Inspections, identify and resolve root causes of failures.
• Support rapid prototyping across ceramics, refractories, metals, and plastics.
• Lead and participate in design reviews, project planning, schedule estimation, and
• progress reporting to cross-functional teams.
• Support supplier, manufacturing, and construction activities through site visits up to
• 20% of the time
• Support production ramp-up at local facility as-needed, including troubleshooting
• and resolving pilot line trials, debugging nonconformances, and dispositioning MRB
• questions

• Bachelor’s or Master’s degree in Mechanical Engineering or a related discipline.
• 2+ years of relevant mechanical engineering experience involving complex
• mechanical systems
• Experience taking mechanical designs from concept through qualification and
• production
• Demonstrated design experience with high-temperature materials, thermoselectro-mechanical systems, and mechanical interfaces for high-voltage systems
• Proficiency in FEA and 1D thermal analysis
• Experience applying GD&T principles and connecting critical features and tolerance
• stack-ups to functional performance
• A commitment to schedule execution, high-quality documentation, and engineering
• rigor
• A track record of applying sound engineering judgment to evaluate requirements,
• challenge assumptions, and recommend scope, cost, or technical tradeoffs to meet
• performance and schedule objectives
• Excellent technical communication and cross-functional collaboration skills.
• Able to lift up to 50lbs

• Experience performing CFD analysis
• Knowledge of relevant electrical and mechanical design standards and
• considerations including creepage and clearance and arc-flash protection
• Experience supporting field installation or commissioning of complex industrial or
