Antora Energy delivers affordable, reliable energy to industry, data centers, and the grid. Our thermal batteries turn low-cost electricity into always-on heat and power, without supply-constrained critical minerals or multi-year construction timelines.

We are growing our company with people who put team and mission first, value connection through laughter and joy, and work with humility and openness. We are committed to building a diverse, passionate, and creative team dedicated to a future powered by abundant, clean, low-cost energy.

Position Summary

Antora is scaling production while preparing the newest generation of our product and a new gigafactory to build it in. We are looking for an engineer who can take a product concept and carry it all the way to a running process: define the build sequence, design the process and the custom tooling that enables it, and integrate it on the floor. Someone who takes full ownership of that arc, starts to finish, working closely with design engineering, production, and the technicians who will build with what they create. This is a hands-on design role: you will personally design, analyze, and release the fixtures, work cells, and safety-critical lifting and handling equipment that production runs on. The tooling and processes you design will set production rates, enable new product launches, and shape the next-generation build process before the factory around it is committed.

Roles & Responsibilities

Develop the next-generation production process, tooling, and equipment

  • Partner with design engineering to define the build sequence from the product concept
  • Review product designs early, from concept reviews onward, and drive manufacturability into them before designs harden
  • Lead process, tooling, and workcell design for your subsystems, carrying designs from concept through analysis, detailed design, and release
  • Develop the associated work instructions and PFMEAs

Support the new gigafactory launch

  • Translate the production process into facility requirements: layout, material flow, workstation footprints, and tooling and equipment needs
  • Partner with factory planning and capital equipment owners through launch

Own station scope and strengthen the current line

  • Own your stations through production support and as products evolve through new versions
  • Develop and integrate production test processes and rigs: implement design-defined test requirements on the line while maintaining takt, line balance, and rework access
  • Share in the team's standing work: EVT build support, process plan and work instruction releases, change incorporation, issue triage and root cause, tooling upkeep, and equipment commissioning
  • Improve safety through partnership with production and EH&S

Contribute to Antora's culture

  • Put team and mission first
  • Invite critique early and treat feedback as material that strengthens the work
  • Be someone technicians and engineers want building next to them

Key Qualifications

  • Bachelor's degree in Mechanical, Manufacturing, or Industrial Engineering, or equivalent practical experience
  • 5+ years in manufacturing or NPI engineering, including personally designing tooling and equipment for a production environment
  • Proven ability to take products from concept to build sequence to running process, with designs carried through detailed design, GD&T, and formal change control
  • Structural analysis capability: FEA and hand calculations applied to real hardware, with sound judgment on loads, factors of safety, and safety-critical equipment
  • Grounded in DFM, lean manufacturing principles, and PFMEA and work instruction development
  • Strong cross-functional collaborator, decisive with incomplete information, and comfortable in a fast-moving startup environment
  • Ability to travel domestically as needed, up to approximately 25% during factory launch periods, with typical travel expected to be significantly lower

Additional Qualifications Desired

  • Experience launching a new factory or production line from the ground up, including capital equipment specification and vendor-built tooling
  • Experience developing production test systems and validation methods
  • Experience with MES/PLM systems, BOM structuring, and formal change management in a production environment
  • Experience with battery, energy storage, or other thermally or electrically demanding hardware products

What They Do

Antora Energy is a pioneering private renewable energy company that specializes in thermal energy storage solutions aimed at decarbonizing industrial heat and power. Founded by a team of experts with advanced degrees from Stanford and MIT, the company focuses on innovative technologies such as thermophotovoltaics (TPV) and scalable energy systems. Their core product is a modular thermal battery that stores renewable electricity as heat in solid carbon blocks, which can be heated to extremely high temperatures for multi-day storage and then discharged as industrial heat or electricity (source: research.contrary.com; antora.com).

The technology is designed to address the significant emissions produced by the industrial sector, which accounts for nearly one-third of global emissions. Antora's thermal batteries are capable of achieving over 40% heat-to-electricity conversion efficiency, making them a cost-effective alternative to traditional energy storage solutions. The company targets heavy industries such as chemicals, mining, food and beverage, oil and gas, cement, and steel, providing solutions that require continuous high-temperature heat and power (source: energy.mit.edu; antora.com).

Antora differentiates itself from competitors by offering dual heat and power output, high efficiency of TPV cells, and the ability to operate at extreme temperatures. Their manufacturing operations are based in the United States, ensuring quality and reliability in production. The company also employs a Heat-as-a-Service model, allowing clients to avoid upfront capital costs by installing batteries and purchasing heat or electricity under long-term contracts (source: antora.com; cbinsights.com).

Projects & Track Record

In 2023, Antora Energy successfully commissioned its first commercial-scale thermal battery, a 5 MWh system located near Fresno, California. This project, developed in partnership with Wellhead Electric, is notable for being the world's first operational thermal battery utilizing carbon blocks and TPV technology, providing continuous industrial heat and power. This pilot project marks a significant milestone in Antora's journey towards commercial deployment across various sectors, with plans for future projects in industries such as chemicals, mining, food and beverage, and oil and gas, some of which are expected to be operational by 2025 (source: research.contrary.com; energy.mit.edu).

Additionally, Antora opened a state-of-the-art 50,000 square foot manufacturing facility in San Jose, California, in 2023, which is recognized as the world's largest TPV manufacturing operation. This facility is designed to produce TPV cells and assemble batteries, with an annual capacity of 2 megawatts, further solidifying Antora's position as a leader in thermal energy storage technology (source: cbinsights.com; research.contrary.com).

Recent Developments

Antora Energy has made significant strides in recent years, including raising $150 million in a Series B funding round in early 2024, led by Decarbonization Partners, which includes BlackRock and Temasek. This funding brings the company's total equity funding to approximately $204.73 million, aimed at scaling thermal battery production to meet the growing demand for zero-emissions energy solutions. In 2023, the company also launched its commercial-scale batteries and received over $4 million in grants from the California Energy Commission and ARPA-E to support its TPV expansion efforts (source: antora.com; cbinsights.com).

Moreover, Antora's innovative technology earned recognition in 2023, winning TIME’s Best Inventions and Fast Company’s World Changing Ideas awards, highlighting the impact of their thermal battery solutions on the renewable energy landscape. The merger with Medley Thermal has also enhanced Antora's capabilities by integrating software solutions for industrial boiler systems, further improving deployment efficiency (source: research.contrary.com).
