R&D Engineer (Mechanical Engineer)

Overview

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 experienced R&D Engineer–Mechanical Engineering to support the design, development, and scale-up of proprietary electrochemical system technologies. This role will contribute to the mechanical design, integration, and manufacturing readiness of electrochemical cells and systems, working closely with cross-functional teams of engineers and scientists. The R&D Engineer (Mechanical Engineer) will play a key role in translating bench- and pilot-scale concepts into robust, reliable, and manufacturable mechanical designs, including the design of bench-scale and pilot-scale equipment. In addition, this position will support pilot plant upgrades, equipment modifications, and continuous improvement initiatives, contributing directly to the development and optimization of pilot-scale hardware.

Salary Range : $100,000 – $130,000 annually, depending on experience and qualifications.

Key Responsibilities

• Contribute to the mechanical design and development of components and assemblies for electrochemical cells, stacks, and balance-of-plant systems, ensuring structural integrity, sealing, thermal management, manufacturability, and serviceability.
• Perform mechanical and thermal analyses, including CFD simulations, to evaluate fluid flow, heat transfer, pressure drop, and overall system performance.
• Collaborate with R&D teams to support scale-up from bench-scale to pilot- and demonstration-scale systems.
• Interface with manufacturing partners and suppliers to ensure manufacturable designs, cost-effective assembly methods, and appropriate tolerances.
• Develop, review, and maintain mechanical drawings, specifications, and CAD documentation.
• Support testing activities by analyzing performance data, identifying mechanical failure modes, and implementing design improvements.
• Contribute to design reviews, risk assessments, and continuous improvement initiatives.
• Support pilot plant mechanical upgrades, including equipment modification, installation, commissioning, and troubleshooting.
• Support the mechanical design and scale-up of chemical process equipment and unit operations, including systems involving fluid flow, heat and mass transfer, and solids handling, for bench- and pilot-scale deployment.
• Maintain a working knowledge of process control systems and instrumentation, enabling effective collaboration on control strategies, sensor selection, and automation for bench- and pilot-scale equipment.
