Senior Manufacturing Engineer New Alameda, CA

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 rapidlyscaling,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 hands-on Manufacturing Engineer to lead the development, optimization, and scale-up of the assembly processes behind our modular thermal battery system, taking it from early prototype through high-volume production. You will partner closely with design, supply chain, and field deployment teams to build robust, data-driven manufacturing processes that deliver on quality, cost, and throughput in a fast-paced, high-growth environment.

(key responsibilities for this role include but are not limited to):

• Develop, optimize, and validate the assembly process for the modular thermal battery system from prototype through scaled production.
• Build virtual process models using value stream mapping, process flow software, and simulation tools to evaluate alternative configurations and process scenarios.
• Lead the development of standardized, data-driven production processes using IoT, SPC, and modern manufacturing analytics tools.

• Collaborate closely with design engineering, supplier quality, sourcing, and manufacturing partners to transition designs into robust, scalable production.
• Own Design for Manufacturing (DFM) and Design for Assembly (DFA) guidance, influencing mechanical and thermal subsystem design to enhance quality, cost, and throughput.
• Drive iterative learning from field performance back into product and manufacturing process improvements.

• Define, procure, and implement tooling, jigs, fixtures, test equipment, and process automation required for reliable, high-yield assembly.
• Develop and maintain build documentation, assembly instructions, PFMEAs, control plans, and supplier qualifications.
• Support packaging, logistics, and pre-commissioning validation through coordination with field deployment teams.

• Own module-level manufacturing costing—including CAPEX, OPEX, labor, utilities, facilities, scrap, and throughput assumptions.
• Provide inputs to BOM development, installation timelines, and overall project planning.

• Bachelor’s or Master’s degree in Mechanical Engineering, Electromechanical Engineering, Manufacturing Engineering, or related discipline.
• 5–8 years of experience developing manufacturing processes and equipment for new hardware products; experience in startup or high-growth technology environments strongly preferred.
• Proven experience managing full-lifecycle equipment or automation projects—including scoping, design, installation, commissioning, and budget oversight.
• Hands-on technical ability with a track record of debugging, troubleshooting, and improving new production lines or early-stage processes.
• Deep knowledge of continuous improvement, root cause analysis, and structured problem-solving methodologies.
• Demonstrated success collaborating closely with design engineering teams and influencing product architecture through DFM/DFA input.
• Experience in fast-paced, complex hardware environments.
• Strong commitment to product quality, safety, cost reduction, and process reliability.

• Life Insurance and ADD
• Up to 12 paid holidays per year, in addition to a company week-long holiday in December
• Flexible time off policy
• 401(k) plan with company match
• Cell Phone Reimbursement
• Catered lunches on-site
