Our cutting-edge solutions enable unparalleled “time-to-power” capabilities, reliability, and sustainability, ensuring our customers remain ahead in a world where soaring energy demand and intensifying energy scarcity are rapidly becoming the new norm. At Bloom, we thrive on collaboration, bold thinking, and relentless innovation.

We believe that, together, we can create a brighter, more sustainable future while tackling the most pressing challenges of the 21st century. We are looking for a Senior Technologist
- Strategic Materials to join our team in one of today’s most exciting technologies.

This role will report to the Director Supply Chain, Commodity Leader and will be based in San Jose, CA. This is a fully on-site, 5 days in office role. The Senior Technologist
- Strategic Materials will lead hands-on process development, optimization, and scale-up of hydrometallurgical systems for critical and rare earth metals production. This role is ideal for someone with deep technical experience in wet chemistry, aqueous processing, leaching, precipitation, separation, purification, and pilot-scale development who wants to build real-world industrial processes, not just model them. This position will play a key role in translating laboratory results into scalable process designs that support Bloom Energy’s supply chain from process flow sheet to pilot plant to production deployment.

You will work closely with R&D, engineering, and operations teams at Bloom Energy and at Supplier Partners to design experiments, troubleshoot complex process challenges, develop operating parameters, and guide junior engineers and scientists.

Process Development:

• Design and run lab- and bench-scale tests for unit operations like leaching, solvent extraction, ion exchange, and precipitation.
• Lead the design, execution, and analysis of hydrometallurgical experiments involving leaching, purification, precipitation, solid-liquid separation, solvent extraction, and related critical metals processes
• Develop and optimize process conditions for laboratory, bench-scale, and pilot-scale hydrometallurgical systems
• Provide technical leadership for wet chemistry work, including solution chemistry, acid-base chemistry, pH control, filtration, precipitation, reagent selection, and process troubleshooting

Scale-Up & Operations:

• Translate bench chemistry into pilot-plant or commercial-scale operating flows, ensuring economic and technical viability.
• Support equipment sizing and selection for reactors, filtration systems, thickeners, mixer-settlers, tanks, pumps, and other hydrometallurgical process equipment
• Lead root-cause analysis and troubleshooting for process performance issues, including recovery losses, impurity behavior, phase separation challenges, and process instability
• Collaborate with engineering, R&D, and operations teams at Bloom Energy and at Supplier’s to develop pilot-scale test plans, operating procedures, and process control strategies
