Senior/Staff Mechanical Engineer – Product Development

About the role

Antora Energy is seeking a self‑driven Senior or Staff Mechanical Engineer to join its Product Development team in San Jose. You will own the design, analysis and validation of subsystems that enable the company’s thermal‑battery technology, driving the demonstration and deployment of a first‑of‑a‑kind long‑duration energy storage solution.

Key responsibilities

• Lead architecture, detailed design and testing of structural, thermal and fluid components within the thermal battery.
• Perform calculations, finite‑element analysis (FEA) and trade studies to guide design decisions.
• Drive prototyping, testing and root‑cause analysis to ensure robust, reliable hardware.
• Identify cost‑down opportunities in design and manufacturing without sacrificing performance.
• Define system requirements, lead design reviews and integrate cross‑functional feedback.
• Develop and maintain CAD standards, documentation and engineering infrastructure.
• Mentor junior engineers and serve as technical lead.

Required profile

• Bachelor’s degree in Mechanical Engineering with 6+ years (Senior) or 10+ years (Staff) relevant experience, or equivalent Master’s/PhD qualifications.
• Proven track record taking complex mechanical systems from concept to deployed hardware in power generation, aerospace, propulsion or similar industrial hardware.
• Strong proficiency with CAD (SolidWorks or similar), PDM systems and detailed GD&T drawings (ASME Y14.5).
• Experience with machined components for low‑ to mid‑volume production; sheet‑metal, casting or composite experience a plus.
• Expertise in structural and/or thermal analysis using FEA and hand calculations.
• Familiarity with systems analysis and risk‑management tools such as FMEA.
• Experience establishing engineering processes, standards and best practices.
