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 is accelerating industry's transition to lower-cost, zero-carbon heat and power.
Our Rondo Heat Batteries turn low-cost renewable electricity into continuous, high-temperature heat and power, enabling industrial facilities to replace fossil-fired boilers without costly process changes. The result is lower-cost, zero-carbon industrial energy delivered safely, reliably, and at 98% efficiency.
Rondo is commercially deployed and rapidly scaling, today. Backed by world-class industrial leaders and investors - including Breakthrough Energy, Energy Impact Partners, Rio Tinto, Aramco, SABIC, SCG, TITAN, Microsoft, H&M, and John Doerr - Rondo is building the next generation of industrial energy infrastructure at global scale.
We are looking for a Madrid-based Principal Process Safety Engineer to own and lead Rondo's global risk-based process safety management program. This person will serve as the company's principal technical authority for hazard evaluation across all sites (US, Germany, Portugal, Thailand, Australia), set the global process safety standard with local adaptation, personally lead the highest-risk and most complex studies, and build and qualify distributed facilitation capability so the program runs across geographies without depending on a single person. This is an opportunity to stand up a world-class PSM program at a fast-scaling, first-of-a-kind energy technology company.
What You Will Do
- Own and scale Rondo's global risk-based PSM program, including periodic re-determination of regulatory applicability across jurisdictions (OSHA PSM / CalARP in the US; Seveso III in the EU; Major Hazard Facility / WHS regimes in Australia; applicable Thai requirements) so program rigor tracks actual process risk and inventory as each site grows
- Own the global PHA methodology and standard (HAZID, HAZOP, LOPA); personally facilitate high-risk and complex studies, and calibrate, and oversee local facilitators at each site so quality is consistent worldwide
- Own the global PHA action register and governance; drive closure by assigning accountability to line/engineering owners, tracking to completion, and escalating overdue high-risk actions to leadership
- Serve as the mandatory process safety reviewer within the Management of Change process, ensuring changes are screened for process safety impact and trigger PHA revalidation where required; own Pre-Startup Safety Review (PSSR) and maintain Process Safety Information (PSI) as the system of record
- Build process safety competency across the global organization - develop and deliver HAZOP/PHA leader and team-member training, and establish a qualified network of local facilitators and process safety champions so the program is not single-threaded
What You Will Bring
- BS in chemical, mechanical, process, or related engineering; ~10-15+ years of process/process-safety engineering experience with a demonstrated record independently facilitating full HAZOP/PHA studies
- Multi-site or international process safety experience; working command of PSM elements (PHA, PSSR, PSI, MI interface, incident investigation); willingness to travel internationally (est. 25-40%)
- Ability to apply hazard-evaluation and risk-ranking methods (HAZID, HAZOP, what-if, LOPA) and translate findings into risk-based, prioritized recommendations
- Knowledge of process safety hazards specific to thermal energy storage - high-temperature stored thermal energy, high-voltage/arc-flash, pressure/steam systems, and stored-energy isolation
- Ability to apply functional safety lifecycle practice (IEC 61511; SIF/SIL determination and verification) and select and justify appropriate RAGAGEP
- Ability to evaluate program effectiveness using process safety leading and lagging indicators (e.g., API 754-style tiered metrics), audit findings, and global action-closure data
- Ability to harmonize multi-jurisdiction regulatory and corporate requirements into a single global standard with defensible local adaptation, rather than running disconnected per-site programs
- Track record of independently challenging designs and operating plans on a risk basis, including the authority to flag and halt unacceptable risk - without being the author of the controls under review
- Experience leading cross-functional hazard-evaluation teams across cultures and time zones; ability to drive consensus on risk and safeguards in geographically distributed settings
- Ability to prioritize the highest-risk processes and overdue safety-critical actions for resources and attention globally
- Strong ability to influence and escalate across line and leadership without direct authority; experience mentoring engineers and serving as a principal technical reviewer
Bonus Points!
- First-of-a-kind / novel-technology hazard analysis - you've evaluated processes where no established RAGAGEP exists and had to reason from first principles
- Energy storage, batteries, power generation, or high-temperature/molten-media background
- Hands-on functional safety - FMEDA, SIL verification, SIS design, not just IEC 61511 awareness
- Human and Organizational Performance fluency - treats "human error" as the start of a system-design question, not a root cause
- Functional safety experience (IEC 61511) or TÜV Functional Safety Engineer certification
- CCPSC (CCPS Certified Process Safety Professional)
- Experience harmonizing process safety programs across jurisdictions (Seveso, WHS MHF, etc.)
What We Offer
- Comprehensive Medical Benefits
- Very competitive salary plus equity in a quickly-scaling company
- A centrally-located Madrid office
- Opportunity to impact industrial carbonization on a daily basis
