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).

Working There

Antora Energy offers a range of career opportunities across various departments, including engineering, software integration, commercial operations, and research and development. The company is particularly focused on hiring talent to support its manufacturing operations and project deployments, with job openings primarily located in their Sunnyvale and San Jose offices. The culture at Antora emphasizes rapid iteration and collaboration among a team of professionals with backgrounds from prestigious institutions like Stanford and MIT, fostering an environment that is mission-driven and focused on deploying large-scale battery solutions globally (source: climatetechlist.com; research.contrary.com).

While specific employee benefits are not extensively documented, the company's Heat-as-a-Service model and focus on long-term operations suggest a commitment to stability and predictability for its workforce. Antora's emphasis on creating jobs in the US is also highlighted in their funding announcements, reflecting their dedication to contributing positively to the local economy (source: antora.com).

Position Summary

Antora is seeking a well-rounded, high-initiative leader with deep subject-area expertise in III-V MOCVD epitaxial growth on InP substrates to lead the thermophotovoltaic (TPV) epitaxy program end-to-end. The role involves designing epitaxy development campaigns and managing the external suppliers who execute them. This requires deep knowledge of epitaxy and materials, designs of experiment, characterization techniques, data analysis, and investigative skills. The role also requires exceptional soft skills to manage supplier relationships, provide clear instructions, negotiate timelines, pricing, and deliverables, and to work through technical and commercial issues with suppliers that arise in the course of the work. Lastly, this individual will drive the epitaxy development strategy to maximize learning speed while controlling cost. This includes driving the make-vs-buy decision on vertically integrating epitaxy R&D.

This is a unique role with the ability to shape the success of the entire TPV program, the technology at the heart of Antora's differentiating heat-to-power conversion approach. The role reports to Antora's Head of Heat-to-Power.

Roles & Responsibilities

  • Lead multijunction TPV epitaxy development. Drive the design and development of multijunction III-V TPV device epitaxy to meet electrical, optical, and cost targets. This especially includes tunnel junctions, quaternary absorbers, quantum wells, fast growth rates, etc.
  • Own technical and commercial epitaxy supplier management. Design and communicate experimental epitaxy campaigns; establish consistent calibration routines and repeatable processes; maintain data-driven specifications; negotiate timelines and pricing with suppliers; submit RFQs and POs; and manage campaign learning cycles in coordination with the device fabrication team, including data analysis and coordination of supplementary characterization (SIMS, SEM, TEM, etc.).
