Job description

Overview

Antora builds and deploys thermal batteries to power always-on industrial operations with low-cost energy. Factory-built in the United States, Antora's modular thermal batteries deliver reliable heat and power, enabling industrial facilities of any size to decarbonize predictably and profitably. Antora is electrifying global industry while supporting U.S. manufacturing jobs, lowering costs for energy consumers, and enhancing the competitiveness of American industry.

We are growing our company with people who put team and mission first, value connection through laughter and joy, and build with humility and openness. We are committed to continue building a diverse, passionate, and creative team dedicated to a future where every industrial facility, everywhere on earth, is powered by abundant, clean, low-cost energy.

Position

Senior Materials Process Engineer to lead the design, implementation, and optimization of high-temperature mechanical processes and components critical to our thermal energy storage systems. In this role you will be directly responsible for developing novel materials and the industrial process to produce those materials to meet Antora's need for significant thermal battery production in 2026.

Your contributions will directly impact Antora's ability to scale manufacturing, improve part quality, and reduce system costs.

Responsibilities

• Lead the design and validation of high-temperature (>1000°C) thermal process equipment and associated hardware.
• Develop and execute rigorous Design of Experiments (DOEs) to establish robust and scalable manufacturing processes.
• Define requirements for custom fixtures and tooling, particularly in stainless steel and other high-temperature-capable materials.
• Generate detailed part and assembly design files (CAD) for prototyping and production.
• Collaborate closely with furnace operators, machinists, and fabrication partners to bring designs to life, from concept through final processing and inspection.
• Analyze process performance and quality metrics to identify root causes of yield loss and implement cost-effective improvements.
• Support the transition of designs from R&D to scaled production.
• Continuously improve part quality, repeatability, and throughput while lowering costs.

Key Qualifications

• B.S. or higher in Mechanical Engineering, Materials Science, or a related field.
• 5+ years of experience in mechanical process engineering, manufacturing engineering, or related roles.
• Demonstrated experience with high-temperature systems (≥1000°C), including thermal process equipment or furnace design.
• Strong background in fixture and tooling design for metal components.
• Proficiency in CAD software (e.g., SolidWorks, Inventor, NX, or equivalent).
• Experience working directly with machinists and fabricators to develop functional prototypes and qualifying production parts.
• Hands-on experience executing DOEs and analyzing experimental data.
• Demonstrated experience in project management (>$2MM budget) & direct executive communication.
• Direct experience with novel material development.
• Direct experience with zero-to-one hardware development.

Additional Qualifications Desired

• Familiarity with high-temperature material properties, failure modes, and thermomechanical design principles.
• Experience in startup or high-growth manufacturing environments.
• Exposure to thermal battery systems or other energy storage technologies.
