Electrolyzer Engineer information

What does an electrolyzer engineer do?

An Electrolyzer Engineer is responsible for designing, developing, and optimizing electrolyzer systems that split water into hydrogen and oxygen using electricity. They work on improving the efficiency, performance, and durability of electrolyzers to support hydrogen production, often for use in clean energy applications. Their role involves selecting materials, conducting experiments, troubleshooting technical issues, and collaborating with teams to scale up the technology. Electrolyzer Engineers play a crucial part in advancing the hydrogen economy and enabling the transition to sustainable energy sources.

What are the key skills and qualifications needed to thrive as an electrolyzer engineer, and why are they important?

To thrive as an Electrolyzer Engineer, you need a solid background in chemical, mechanical, or electrical engineering, with expertise in electrochemistry and hydrogen production technologies. Familiarity with modeling software (such as COMSOL or Aspen Plus), PLC systems, and relevant industry certifications is typically required. Strong problem-solving skills, attention to detail, and effective teamwork and communication abilities help engineers excel in this field. These skills and qualifications are essential for designing, optimizing, and maintaining safe, efficient electrolyzer systems critical to clean energy initiatives.

What are some common challenges electrolyzer engineers face when integrating new electrolyzer technology into existing energy systems?

Electrolyzer Engineers often encounter challenges related to system compatibility and scalability when integrating new electrolyzer technology with current energy infrastructure. Adapting to fluctuating power sources, such as renewables, and ensuring seamless communication with grid management systems can be complex. Additionally, engineers must address issues like system efficiency, hydrogen purity, and the safe handling of high-pressure gases. Collaboration with cross-disciplinary teams, including electrical engineers and safety specialists, is essential to successfully overcome these challenges.

What is the difference between Electrolyzer Engineer vs Fuel Cell Engineer?

AspectElectrolyzer EngineerFuel Cell Engineer
CredentialsBachelor's in Chemical, Electrical, or Mechanical Engineering; relevant certificationsBachelor's in Chemical, Electrical, or Mechanical Engineering; relevant certifications
Work EnvironmentResearch labs, manufacturing plants, renewable energy facilitiesResearch labs, automotive, aerospace, and energy sectors
Industry UsageHydrogen production, renewable energy storageHydrogen fuel cells, clean energy applications

Both roles require similar educational backgrounds and certifications, often working in research or industrial settings. While Electrolyzer Engineers focus on producing hydrogen via electrolysis, Fuel Cell Engineers develop systems that convert hydrogen into electricity. They share skills but differ in application focus within the renewable energy industry.

Job description

Senior Manufacturing Engineer Oversee end-to-end manufacturing of electrolyzer systems for scalable production

Location: Los Angeles, California

About The Role Senior Manufacturing Engineer

Hgen's mission is to achieve a clean and renewable energy future through providing foundational molecules for critical industries. By enabling cheap and abundant clean hydrogen, Hgen aims to help decarbonize the more than 10% of global emissions that are best addressed with hydrogen. Learn more about why clean hydrogen is critical for achieving zero-emissions.

As a Senior Manufacturing Engineer, you own the planning and execution of the electrolyzer stack, balance of plant, and any necessary tooling. You will work closely with design engineers to ensure the systems can be produced effectively, efficiently, and at accelerating rates. This role offers the opportunity to work in a fast-paced, collaborative startup environment, where your contributions will have a direct impact on the future of decarbonization.

Responsibilities
  • Coordinate cross-functional efforts across design, supply chain, and production to execute the build process: covering planning, sourcing strategies, sequencing, MBoM development, tooling, equipment and work order creation
  • Author work instructions and processes that allow interdisciplinary teams to build effectively while ensuring quality standards are met
  • Manage production team priorities, offer technical direction, drive execution, and support professional development of team members
  • Support manufacturing and assembly shop layouts
  • Design production tooling, jigs, and platforms to improve build consistency and rate
  • Other duties as assigned
Basic Qualifications
  • Bachelor's degree in a relevant engineering discipline (mechanical, aerospace, etc.)
  • 5+ years of experience building complex mechanical systems
  • Strong understanding of fundamental principles in mechanical and fluid systems
  • Ability to lift up to 50 lbs unassisted
  • Able to work on-site in Hawthorne, CA
Preferred Skills & Experience
  • Proven ability to interface with multidisciplinary functions of mechanical, electrical, and fluid systems
  • Experience and demonstrated proficiency in developing and implementing comprehensive work instructions and test procedures
  • A history of working directly with hardware and subsystems including, instrumentation, power systems, hazardous fluids, and structures in a controlled environment
  • Experience working on build, test of complex assemblies at the system and subsystem level
  • Experience with scaling manufacturing processes from development through rate production
Professional Qualities
  • When given a set of guiding objectives and principles, you can identify, prioritize, and execute on tasks with minimal supervision
  • A willingness to jump in and work side-by-side with technicians
  • You have strong organizational, documentation follow-through skills and take pride in the quality of your work
  • You are passionate about decarbonization and addressing climate change
