Who We Are

Lithium is the wonder metal that sits at the heart of the global shift to EVs. Although EV demand is skyrocketing, global lithium supply cannot keep up using traditional extraction methods. The only way the industry will be able to scale lithium supplies by 10 times is by efficiently extracting the element from brine deposits, which contain about three quarters of all known lithium reserves.

Lithios is a technology company based in Medford, MA, commercializing a breakthrough electrochemical process called Advanced Lithium Extraction (ALE). ALE uses renewable electricity to make lithium cheaply, safely, and with a lower carbon footprint. Moreover, ALE is more versatile than traditional extraction methods and can unlock huge untapped lithium resources in the US and globally, alleviating a major bottleneck in the global transition to EVs.

We are building a diverse and collaborative company. Our employees put team and mission first, build with humility and compassion, and strive to make the world a better place. We are a high-growth startup backed by world-leading organizations and investors. At Lithios, we wake up every day to do the most fulfilling, impactful work of our lives. Come change the world with us!

Position Overview

Lithios seeks an electrochemical engineer who will work with the research, development, and engineering teams to deliver solutions in the following areas:

• designing and continuously improving our electrochemical methods and systems for selective lithium extraction from complex multicomponent mixtures, via experimental and theoretical techniques;

• Proficiency with fluid mechanics, aqueous solution chemistry[A1] , and/or electrochemical methods (e.g.: voltammetry, cell cycling, EIS).
• Basic familiarity with hands-on prototyping, including design (e.g.: CAD) and fabrication (e.g.: machining, 3D printing).
• Experience with flow devices and power supplies, including assembly of cells or stacks and/or management of water and flows, is a plus.
• Experience with Microsoft Excel and tools, such as MATLAB, Python, or COMSOL, for quantitative data analysis and basic engineering calculations and simulations.
• Ability to work hands-on in the lab individually and as a team.
• Strong organizational and documentation skills and the ability to deliver effective technical communication.
• The desire to be in a dynamic startup environment with a focus on critical thinking to find impactful solutions to difficult challenges.

Key Responsibilities

• Operate electrochemical systems and quantitatively evaluate device and process performance for target system configurations and process inputs.
• Design and conduct experiments to investigate the impacts of device design, electrode design, and operating protocol on overall process performance.
• Collaborate with the engineering team to aid in the design and scaleup of the electrochemical extraction system.
• Maintain an active database compiling lithium extraction knowledge, techniques, and operating procedures.
• Communicate technical challenges and results across the organization to advance product development.

Compensation and Benefits

• Competitive salary.
• Equity in the company.
• A 401(k) plan with employer matching.
• Medical, dental, and vision insurance are 100% covered.
• Commuter benefits and public transportation expenses are 100% covered.
