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

We are looking for a Senior Model-Based Systems Engineer - Integration, Verification & Validation (IV&V) to own interface management and the full system verification and validation program across Rondo's products. This role is responsible for planning, defining, and reporting on all integration and V&V activities, from requirements through final evidence packages.

What You'll Do

Interface Management

  • Own all interface boundary definitions and configuration control; author and maintain Interface Control Documents (ICDs), delegating responsibility to subsystem leads where appropriate to ensure 100% interface coverage and oversight.
  • Use interface analysis methods - context diagrams, N2 diagrams, functional analysis, FMEA/STPA, etc. - to identify interactions, assess risks, and define requirements; maintain bidirectional traceability to the system architecture and V&V artifacts.
  • Plan and define interface verification activities; coordinate cross-functional review and approval of interface changes; ensure every change triggers an impact assessment.
  • Verify that discipline engineers are performing clash detection, envelope compliance, and tolerance stack-up checks correctly in a federated CAD/PLM model.

V&V Planning and Definition

  • For every requirement, define the V&V success criteria, strategy, and method across a combination of model-based simulation and physical testing.
  • Develop V&V plans for system, subsystems, and system elements; author procedures; schedule verification events and enforce a logical bottom-up integration sequence.
  • Work in close collaboration with subsystem and functional to confirm plans are comprehensive.
  • Collect evidence from execution teams, review for correctness and completeness, manage discrepancies and noncompliance through to closure, and assemble the final compliance summary.
  • Plan and define V&V for all phases of on-site commissioning.

Toolchain Integration and Workflow Automation

  • Build and maintain automated workflows in an AI-powered systems engineering platform to connect requirements, interfaces, simulations, verification status, interface changes, and traceability into a live, continuously updated picture of program health.
  • Author AI skills to automate repetitive SE tasks: requirements quality checks, coverage gap detection, interface impact analysis, and verification status roll-ups.

Reporting and Compliance

  • Maintain end-to-end bidirectional traceability from stakeholder needs through requirements, interfaces, risks, and verification evidence.
  • Present verification readiness and evidence status at program reviews; produce compliance summaries and requests for variance or concessions where needed.
  • Ensure functional safety (IEC 61511), cybersecurity (IEC 62443), and other regulatory requirements are fully evidenced; apply risk-based prioritization.
