Employee count is not publicly specified, and as a private company, no revenue figures are disclosed; total funding raised is $82 million (source: cbinsights.com).

What They Do

Rondo Energy focuses on electrified thermal energy storage, specifically through its innovative Rondo Heat Battery (RHB) technology. This technology converts intermittent renewable electricity from sources such as wind and solar into high-temperature heat, which is stored in refractory bricks heated to temperatures between 1100-1500°C. The stored energy can then be dispatched as superheated air, process heat, steam, or power with an impressive efficiency of over 98% for extended periods, making it a viable solution for industries that require continuous high-temperature heat (source: rondo.com). Rondo's products are particularly targeted at sectors like steel, cement, chemicals, food processing, biofuels, textiles, and mining, where high-temperature heat is essential for operations. The company offers scalable systems ranging from pilot-scale deployments to larger commercial applications, catering to a diverse range of industrial needs (source: cbinsights.com). By providing a cost-effective alternative to lithium-ion batteries, Rondo differentiates itself in the market, focusing on thermal storage solutions that do not rely on rare materials, thus enhancing sustainability and accessibility for heavy industries globally (source: weforum.org).

Projects & Track Record

Rondo Energy has made significant strides in the deployment of its Heat Battery technology, with its first pilot-scale 2 MWh Heat Battery operational since 2023 at a California ethanol production facility. This deployment marks a pivotal moment for the company as it represents its initial major project in the field (source: canarymedia.com). The company has announced a total of 11 commercial developments, including 8 RHB deployments that collectively exceed 200 MWh. Notably, Rondo is working on a Heat-as-a-Service solution for HEINEKEN, which is powered by on-site solar and grid renewables, with support from major partners like EDP and the European Investment Bank (source: rondo.com). Rondo's partnerships span various industries, including food and beverage, cement production, mining, and textiles, with a total of 3 GWh in committed capacity across four major partnerships (source: rondo.com). The company's geographic presence is primarily in the United States, with its headquarters in Alameda and ongoing projects in California, while also expanding into Europe through its collaboration with HEINEKEN (source: cbinsights.com).

Recent Developments

In the past two years, Rondo Energy has successfully secured a Series B - II funding round, building on a previous $22 million Series A funding closed in February 2022. This funding was led by Breakthrough Energy Ventures and Energy Impact Partners, aimed at enhancing manufacturing capabilities and facilitating customer deliveries (source: rondo.com). The company has made headlines with its HEINEKEN Heat-as-a-Service contract, which was announced as a significant milestone in 2025, alongside the deployment of over 200 MWh across 11 commercial projects (source: rondo.com). Additionally, Rondo was granted a U.S. patent on February 25, 2025, for a thermal energy storage system that integrates with steam cracking systems, showcasing its commitment to innovation in energy storage and conversion technologies (source: cbinsights.com). While no acquisitions or mergers have been reported, Rondo continues to achieve operational milestones and gain recognition from investors for its efforts in addressing industrial heat challenges (source: canarymedia.com).

Working There

Rondo Energy's LinkedIn page indicates that the company is actively hiring for various roles primarily in engineering, manufacturing, project development, and operations. The departments include research and development focused on Heat Battery technology, sales teams targeting industrial clients, deployment teams for project execution, and support functions such as finance, reflecting the company's growth phase (source: linkedin.com). Most hiring efforts are concentrated at the Alameda headquarters, although there may be remote or project-based opportunities associated with U.S. pilots and European expansions like the HEINEKEN project (source: cbinsights.com). The company culture is characterized by a mission-driven approach to decarbonization, emphasizing collaboration with top investors and a commitment to scaling operations for profitability, as highlighted by CEO John O’Donnell in recent funding announcements (source: rondo.com). While specific employee benefits are not detailed in public sources, the venture-backed nature of Rondo suggests competitive compensation packages typical for Series B clean-tech firms in California, including potential equity options (source: linkedin.com).

Job Description

Rondo Energy is seeking a Senior Innovation Engineer focused on thermal power generation for AI. The maturation of our technology, delivery capacity, and IP portfolio now enable us to open a new frontier in power generation that's critically needed to serve the world's data center sprint: the "plug-in hybrid thermal power plant." Rondo Heat Batteries deliver steam at all steam conditions found in thermal power generation systems, up to and including supercritical cycles. Heat battery integrated thermal power cycles achieve improvements in flexibility, operating costs, fuel flexibility, output, and emissions. Drop-in boiler integration and zero-carbon steam changes time to power, permitting, profitability, and peak power.

We're seeking an Innovation Engineer to help us expand the frontier of power-to-power and hybrid renewable + storage applications. In this role, you will work closely with Rondo's innovation and engineering teams, external OEM partners, and prospective customers to develop and evaluate concepts that integrate the Rondo Heat Battery into generation assets and grid-connected systems. You will assess thermodynamic cycles, mechanical design concepts, commercial value, and help design and deliver early installations and enable scaled deployment.

Together we can reduce world CO₂ emissions by 10% in 10 years, and by 15% in 15 years.

What You Will Do

  • Develop and evaluate technical concepts and proposals for Heat Battery integrated thermal power cycles, including simple-cycle, combined-cycle, cogeneration, and fuel conversion involving the Rondo Heat Battery.
  • Lead technical engagements with power producers, OEMs, and technology partners, identify opportunities, define interface requirements, and form the basis for commercialization pathways.
  • Build and manage relationships with major OEMs (turbomachinery, boilers, generators, thermal systems) to align integration strategies, validate performance, and co-develop productized solutions.
  • Conduct techno-economic studies, dispatch simulations, and feasibility analyses to determine system value, operational strategies, and site-specific performance.
  • Design and support pilot programs and early commercial deployments, helping test system value, validate technical assumptions, and systematize learnings for broader market rollout.
  • Translate customer and partner insights into standardized solution packages, tools, and repeatable deployment processes for the commercial team.
  • Work closely with Product, Engineering, and Energy Markets teams to ensure Rondo's solutions remain technically robust, economically compelling, and aligned with evolving market needs.
  • Provide technical expertise during customer meetings, presentations, and industry events to clearly articulate the value proposition of Rondo's solutions.
  • Stay current on power generation trends, grid services markets, relevant regulations, and emerging technologies to inform product and go-to-market strategies.
