Position Summary

We are seeking a self-driven and passionate Senior or Staff Mechanical Engineer to join our Product Development Team. In this role, you will own the design, analysis, and validation of subsystems that make Antora’s thermal battery possible. Your work will directly accelerate the demonstration and deployment of a first‑of‑a‑kind long‑duration energy storage technology.

Roles & Responsibilities

• Own subsystem design: Lead the architecture, analysis, detailed design, and testing of structural, thermal, and fluid components within Antora’s thermal battery.
• Perform rigorous analysis: Apply calculations, finite element analysis (FEA), and trade studies to guide design decisions.
• Drive validation & reliability: Lead prototyping, testing, and root‑cause analysis to ensure robust, reliable hardware.
• Peruse cost‑down: Identify and implement design and manufacturing approaches that reduce cost without sacrificing performance.
• Collaborate cross‑functionally: Define system requirements, lead design reviews, and integrate feedback across teams.
• Establish best practices: Develop and maintain CAD standards, documentation, and engineering infrastructure.
• Mentor & lead: Guide junior engineers and serve as technical lead.

• Strong proficiency with CAD (SolidWorks or similar), PDM systems, and creating detailed drawings (GD&T, ASME Y14.5).
• Deep experience with machined components for low‑ to mid‑volume production; additional experience with sheet metal, castings, or composites is a plus.
• Proficiency in structural and/or thermal analysis (FEA and hand calculations).
• Familiarity with systems analysis and risk management tools such as FMEA.
• Experience developing engineering processes, standards, and best practices.

Additional Qualifications Desired

• Experience designing components for very high‑temperature environments (500–2500 °C).
• Experience with composite and/or brittle materials.
• FOAK (first‑of‑a‑kind) product development from concept through sustaining.
