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
What You Will Do
- Technical leadership across disciplines: Act as the senior technical reviewer for the Project Engineering team's deliverables. You'll be comfortable across mechanical, process, structural, electrical and I&C work - even where it isn't your primary discipline - and you'll set the bar for what's good enough to leave the team.
- Engineering process and quality: Define and own how technical work gets done in Delivery - review gates, drawing and specification checklists, technical bid evaluations, vendor data review, and lessons-learned loops. The bar is that the team's output looks the same regardless of who produced it.
- Project execution support: Partner with Project Managers as the senior engineering counterpart on live projects - unblocking technical decisions, escalating risks early, supporting client and authority reviews, and making sure engineering deliverables land on time, in scope, and at the right quality.
- Vendor, EPC, and customer engineering: Lead engineering interactions with EPC partners, OEMs, and customer engineering teams. Review their submissions critically, hold them to spec, and stay engaged through to resolution when things aren't right.
- People leadership and team building: Lead a multi-discipline team of Project Engineers. Your job is as much to grow them as it is to deploy them - set clear expectations, give honest feedback, and recruit what the team is missing.
- Cross-functional interface with HQ: Act as the Delivery team's primary engineering interface with Product/Design at HQ - translating field learnings into product input and product changes into delivery-ready engineering.
- Safety, compliance, and standards: Make sure projects meet applicable industry codes, regulatory requirements, and Rondo standards, and that safety is treated as foundational during the different project engineering phases.
- Continuous improvement: Keep improving the team's templates, checklists, review standards, and tooling, and feed lessons from each project back in.
What You Will Bring
- Degree in an engineering discipline; Mechanical or Chemical/Process strongly preferred.
- 10+ years of total experience, including 7+ years of hands-on engineering on large industrial, energy, or process plants and 3+ years line-managing engineers.
- All-rounder technical fluency - you can read and challenge work across P&IDs, piping isometrics, equipment datasheets, SLDs, general arrangements and layouts, structural calculations, and I&C/control diagrams, even where it isn't your primary discipline.
- You still enjoy the technical work itself: red-lining a drawing, writing a clean specification, pushing back on a vendor with data. Not just managing the people who do.
- Track record of building, growing, and retaining engineering teams.
- Experience delivering large-scale capital projects (>25 MUSD) in energy, power, oil & gas, chemicals, or heavy industrial.
- Strong leadership, communication, and negotiation skills. Comfortable being the most senior engineer in the room, and equally comfortable saying "I don't know - let's find out".
- Comfortable surfacing problems early, including ones you own. You'd rather have an awkward conversation now than a worse one later.
- Bias to action - you start on what obviously needs doing without waiting to be asked, and bring people along rather than going around them.
- Curious quick learner with strong analytical and problem-solving skills; entrepreneurial and self-motivated.
- Flexibility to work across multiple time zones (Australia east coast through U.S. west coast) and travel internationally to project sites and HQ as required.
- Passion for safety and environmental stewardship.
- Fluent in English (written and spoken); Spanish or other languages a strong plus.
- Valid driver's license.
Bonus Points!
- Background in industrial process plants - anything from Oil & Gas and petrochemicals to biomass, CSP, or combined-cycle power.
- Prior experience building or scaling an engineering team from a small base.
- Experience in a fast-paced start-up environment deploying novel technologies at large scale.
- Familiarity with international project codes (ASME, API, EN, IEC) across multiple jurisdictions.
What We Offer
- Comprehensive Medical Benefits
- Very competitive salary plus equity in a quickly-scaling company
- Opportunity to impact industrial carbonization on a daily basis
This role is hybrid in Madrid and necessitates being on-site at our projects internationally as required for the success of the project.
