Green Hydrogen - Process Systems Engineer - Electrolyzer Systems

Burlington, MA (Greater Boston) On‑Site Full‑Time 3+ Years Experience

Envision Energy is a global green technology company with operations across Asia, Europe, and North America. We design, build, and operate smart wind turbines, develop advanced energy storage and battery systems, and produce green hydrogen — all in service of one mission: solving the challenges of a sustainable future.

Green hydrogen is central to that mission. Made from renewable electricity and water, it is a zero‑emission fuel for the industries that are hardest to decarbonize — steel, chemicals, fertilizer, and heavy transportation. Our H2 Center of Excellence in Burlington, Massachusetts is where we develop and scale the electrolyzer technology that makes it possible: raising efficiency, lowering cost, and bringing production to industrial scale.

We are hiring a Process Systems Engineer to own the design, build, and operation of the water electrolyzer test systems at our H2 Center of Excellence. Candidates with deeper experience will be considered at the Senior Process Systems Engineer level.

This is a hands‑on, end‑to‑end role. You will take hydrogen and oxygen test systems from P& commissioning — specifying and sourcing components, leading safety reviews, getting systems running, and keeping them running. The data your systems produce drives the development of our next generation of electrolyzer stacks, and you'll work directly with the stack, electrochemistry, mechanical, and controls engineers who use it.

• Develop water electrolyzer test systems end to end: design, component specification and sourcing, build, commissioning, operation, and maintenance.
• Lead process safety for hydrogen and oxygen production and handling, including HAZOP and LOPA studies, and make sure the resulting safeguards are implemented.
• Troubleshoot test system failures, then design and execute the fixes.
• Own design documentation through each iteration: P&, PFDs, heat and material balances (HMB), line lists, controls narratives, I/O lists, utility consumption lists, general arrangement drawings, and BOMs.
• Work with stack developers to analyze and report electrochemical performance data.
• Coordinate component sourcing and purchasing with supply chain, and manage technical relationships with vendors, customers, and other external stakeholders.

• Bachelor's or Master's degree in Chemical, Process, Mechanical, or Industrial Engineering, or a related field.
• 3+ years of experience in chemical process engineering or systems design engineering.
• Design experience with industrial process skids and/or electrolyzer or fuel cell test stations.
• Design experience with systems handling hazardous or flammable gases.
• Working knowledge of the mechanical, electrical, process, and controls aspects of system design.
• Strong analytical and problem‑solving skills, with clear written and verbal communication.
• Comfortable working mostly in person in a fast‑paced lab environment — both independently and on interdisciplinary teams.

(if you meet most of the above, we encourage you to apply)

• Experience interpreting and applying industrial codes and standards — for example NFPA 2, NFPA 55, ASME B31.3, or NFPA 70 (NEC) hazardous‑area requirements.
• Experience with functional safety (ISA 84 / IEC 61511) or facilitating HAZOP / LOPA sessions.
• Experience with PLC or DAQ‑based controls, instrumentation selection, and test automation.
• Data analysis of system or electrochemical test data (Python, MATLAB, JMP, or similar).
• Hands‑on experience with PEM or alkaline electrolyzers, fuel cells, or other hydrogen…
