About The Position

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, battery recyclers, or battery manufacturers. The company has attracted funding from Canada Growth Fund, Bill Gates’ Breakthrough Energy Ventures, BDC Capital and BMW I Ventures. The Company has a highly experienced leadership team with a track record of successfully commercializing and deploying industrial technologies and is working towards the deployment of a first-of-a-kind commercial plant. Mangrove is seeking a Senior Mineral Processing Engineer to join our Technology Development Department. This role is ideal for a highly experienced engineer with deep expertise in lithium and mineral processing who thrives in hands-on, pilot-scale environments. You will play a key role in designing, scaling, optimizing, and operating advanced chemical processing systems, with a focus on lithium extraction technologies. This is a high-impact position with significant growth potential in the rapidly expanding battery materials sector. Salary range for this position will be $100 - $140k depending on experience and skills.
