What does an electrolyzer stack engineer do?

An Electrolyzer Stack Engineer is responsible for designing, developing, and optimizing the core components of electrolyzers, which are devices that use electricity to split water into hydrogen and oxygen. Their work involves selecting materials, designing stack architecture, testing prototypes, and improving performance and durability. Electrolyzer Stack Engineers collaborate with multidisciplinary teams to scale up production, reduce costs, and ensure the stacks meet safety and efficiency standards for applications in green hydrogen production and renewable energy.

What are the key skills and qualifications needed to thrive as an electrolyzer stack engineer?

To thrive as an Electrolyzer Stack Engineer, you need a strong background in electrochemistry, materials science, and mechanical or chemical engineering, typically supported by a relevant engineering degree. Familiarity with CAD software, simulation tools, and stack performance testing equipment is crucial, along with knowledge of industry standards and safety protocols. Analytical thinking, problem-solving abilities, and effective teamwork are essential soft skills for optimizing designs and collaborating with multidisciplinary teams. These skills are vital to developing efficient, reliable electrolyzer stacks that advance hydrogen production technologies and meet industry demands.

What are some typical challenges electrolyzer stack engineers face when scaling up designs from prototype to mass production?

Electrolyzer Stack Engineers often encounter challenges related to material durability, manufacturing consistency, and system integration as they move from prototype to mass production. Ensuring that components such as membranes and catalysts perform reliably at scale requires close collaboration with materials scientists and production teams. Additionally, refining the stack design to optimize efficiency while reducing costs is an ongoing focus, and maintaining quality control during high-volume manufacturing can be demanding. Successful engineers proactively address these issues by implementing rigorous testing protocols and working collaboratively across multidisciplinary teams.

What is the difference between Electrolyzer Stack Engineer vs Electrolyzer System Engineer?

AspectElectrolyzer Stack EngineerElectrolyzer System Engineer
CredentialsEngineering degree, certifications in electrochemical systemsEngineering degree, certifications in renewable energy systems
Work EnvironmentDesign, testing, and development of electrolyzer stacks in labs or manufacturingSystem integration, operation, and troubleshooting of electrolyzer systems
Industry UsageFocused on stack components within hydrogen production facilitiesOversees entire electrolyzer systems in renewable energy plants

Electrolyzer Stack Engineers specialize in developing and testing electrolyzer stacks, focusing on component performance. In contrast, Electrolyzer System Engineers handle the overall system operation, integration, and maintenance. Both roles are essential in hydrogen production, but they differ in scope and responsibilities.

Job description

We are seeking an Electrolyzer Stack Engineer to join our Stack Engineering team. In this role, you will contribute to the development of Electric Hydrogen's current and next-generation electrolyzer stacks, supporting product design, validation, manufacturing, and technology advancement activities. You will collaborate across engineering, manufacturing, quality, and supply chain teams to improve stack performance, reliability, manufacturability, and cost.

You will be based in Devens, MA and report to our Director of Director, Electrolyzer Stack.

Primary Responsibilities

  • Support documentation, maintenance, and verification of electrolyzer stack and stack subcomponent requirements, including primary and interface requirements
  • Support development and maintenance of Design Failure Mode and Effects Analyses (DFMEA) for stacks and stack components
  • Perform engineering analyses to verify stack and subcomponent designs meet performance and reliability requirements
  • Participate in cross-functional design reviews for stacks and stack subcomponents
  • Generate and maintain 3D models and engineering drawings for stacks and stack subcomponents
  • Develop and maintain part, material, and component specifications
  • Support the development, release, and maintenance of Bills of Materials (BOMs)
  • Support development and maintenance of Design Verification Plans and Reports (DVP&R) and coordinate verification activities across functions
  • Participate in engineering change management activities for stacks and stack subcomponents
  • Support development of first article inspection (FAI) and incoming quality control (IQC) plans
  • Collaborate with Supply Chain, Manufacturing, and Quality teams to support procurement, qualification, and production activities
  • Support certification activities related to applicable industry codes and standards
  • Contribute to technology development efforts focused on improving stack performance, durability, manufacturability, and cost
  • Support planning and tracking of project scope, schedules, and budgets for stack development activities

Qualifications

  • BS or MS degree in Mechanical Engineering, Chemical Engineering, or a related engineering discipline
  • 0-6 years of engineering experience in product development, design, testing, or manufacturing environments
  • Experience creating 3D models and engineering drawings using CAD tools
  • Understanding of geometric dimensioning and tolerancing (GD&T) and tolerance analysis principles
  • Experience supporting design, build, and test development cycles
  • Familiarity with requirements management, documentation, and verification processes
  • Knowledge of Design Failure Mode and Effects Analysis (DFMEA) methodologies
  • Experience with Computational Fluid Dynamics (CFD) and/or Structural Finite Element Analysis (FEA)
  • Knowledge of seal and gasket design principles
  • Fundamental understanding of fluid dynamics, heat transfer, mechanics of materials, and mass transport
  • Experience with electrochemical technologies such as electrolyzers, fuel cells, batteries, or related energy systems is preferred
  • Strong problem-solving skills with a willingness to challenge assumptions and seek innovative solutions
  • Self-motivated, hands-on, and able to work effectively in a fast-paced, highly collaborative environment
  • Demonstrated ability to take initiative, identify opportunities for improvement, and drive solutions forward
