Status: Full-Time, Salaried, Exempt

Salary: Salaries at Advanced Ionics are paid bi-weekly

Reports to: Vice President of Research and Development
Position Summary: The Electrolyzer Stack Engineer is responsible for designing and building our next-generation stack, cell, and unified electrode assembly architecture. You will also partner with other team members in designing and optimizing bipolar plates and conducting simulations, designing prototypes, and working with manufacturing teams to produce final products.
Expected Hours of Work: This is a full-time position. Days and hours of the work are Monday through Friday, 9:00am to 5:00pm. Occasional evenings and weekends may be required.
Essential Functions of the Position:

• Lead the design and optimization of electrolyzer stacks, with a focus on improving performance, efficiency, durability, and manufacturability.
• Develop 3D models and perform simulations (e.g., thermal, electrochemical, and mechanical) to validate designs.
• Collaborate with materials scientists to select and validate components, such as electrolyte materials, electrodes, and interconnects.
• Evaluate and integrate sealing technologies and thermal management systems
• Develop and execute test protocols for performance validation and degradation analysis of stack components.
• Analyze experimental data to correlate it with design parameters and propose iterative improvements.
• Work closely with other engineers to ensure stack designs integrate seamlessly with balance-of-plant components.
• Address scale-up challenges for industrial applications, including modular design and mass production considerations.
• Support the development of technical documentation, such as drawings, specifications, and design standards. Identify opportunities for innovation in electrolyzer stack design and contribute to intellectual property development.

You’re the right candidate for this job if you enjoy workplaces where everyone has a voice, if you’re passionate about solving climate change through complex and wonky markets, and if you’re willing to propose a new idea, write a memo, code a script, and turn a wrench, you bring positive energy and are flexible in your position.
We know the right candidate might not check every box in this job description. You could also have important skills we haven't thought of. If you think you’re a great candidate for this role, apply and tell us why. To apply, send us a resume and a few sentences about why you are interested in this position and what you bring to the table. There will be opportunities for us to train you too! We’re looking forward to hearing from you!
About Advanced Ionics:
Our mission is to decarbonize the "hard-to-abate" heavy industrial sectors of the world economy with a new class of electrolyzers.
