Who are we?

Mangrove Lithium, a Vancouver based company, has developed a breakthrough platform for the most cost-effective production of battery grade lithium hydroxide and carbonate from diverse input streams and assets. Mangrove’s modular solution can be scaled to any capacity and co-located with upstream lithium producers or cathode and cell manufacturers. The platform technology is being commercialized for the conversion of waste brines to chemicals and desalinated water. The company recently attracted funding through Breakthrough Energy, BMW i Ventures, and BDC Capital and is working towards the deployment of

a first-of-a-kind commercial plant.

Position

Mangrove is seeking an exceptional Pilot Plant Lead Engineer to play a key role in the development and commercialization of proprietary electrochemical technology. This position reports to the Director of Technology Development.

The Pilot Plant Lead Engineer will provide technical leadership for the operation and experimentation of integrated pilot-scale systems, supporting process development and optimization, scale-up, and customer qualification activities. This role includes planning and executing pilot campaigns, leading pilot plant upgrades, overseeing long-duration test runs, and ensuring the generation of high-quality, reliable experimental data.

The successful candidate will be highly proficient in operating and troubleshooting pilot-scale equipment, maintaining rigorous experimental records, and translating experimental results into clear, actionable technical recommendations for cross-functional stakeholders. This position offers the opportunity to work within a dynamic technology development team and to play a meaningful role in advancing a first-of-a-kind electrochemical platform toward commercialization in the rapidly growing lithium-ion battery sector.

Salary Range: $100,000 – $150,000 annually, depending on experience and qualifications.

Required Education, Skills and Experience

• BSc or MSc in Chemical Engineering, Chemistry, Materials Science/Engineering, Mechanical Engineering, or a related field.

• 10+ years of experience in R&D pilot plant operations, process development engineering, or related technical leadership roles, preferably within electrochemical or chemical process industries.

• Expertise in process engineering, including the development, review, and maintenance of P&IDs, process flow diagrams, and standard operating procedures, with a strong focus on safe, reliable, and scalable pilot plant operations.

• Strong knowledge of industrial electrochemical or chemical processes, with hands-on experience in process development and scale-up, including pilot-to-demonstration plant transitions.

• Proven ability to design and execute pilot campaigns, troubleshoot complex equipment and processes, and implement targeted process improvements to enhance reliability and throughput.

• Demonstrated experience leading and mentoring technical teams (5–10 engineers and technicians), providing day-to-day technical guidance and fostering a culture of technical excellence.

• Familiarity with design of experiments, statistical process control, and data-driven process optimization methodologies.

• Track record of contributing to plant upgrades, process optimization initiatives, and the successful commercialization of novel technologies.

• Excellent critical thinking, problem-solving, analytical, and communication skills, with the ability to collaborate effectively across multidisciplinary and cross-functional teams.

• Registered Professional Engineer with Engineers and Geoscientists BC (EGBC), or the ability to readily become one.
