Process Development Engineer

About Us:

RepAir is a pioneering startup specializing in electrochemical CO₂ capture technology and is currently advancing into the scale-up phase. Our technology is designed for gigaton-scale impact, positioning RepAir at the forefront of the shift toward a carbon-negative future. Delivering a highly efficient, sustainable carbon removal solution, our fully electric process requires minimal energy, operates without solvents, and produces no hazardous waste. As a fast-growing company, we are seeking an experienced and visionary Physicist or Mechanical/Chemical/Process Engineer to develop and commercialize our electrochemical carbon capture technologies.

Position Overview:

In this role you will be a key part of the process development activities for RepAir’s electrochemical CO₂ capture stack platform, translating experimental stack behavior into robust operating windows, system requirements, test methods, and engineering decisions. The role bridges hands-on stack experimentation, data analysis, instrumentation selection, system design input, vendor coordination, and cross-functional technical communication. Key Responsibilities:

• Own ,Design, execute, and analyze experiments from test definition through operation, troubleshooting, data extraction, analysis, and reporting. to advance electrochemical stack performance.
• Develop and refine testing methodologies for evaluating materials, components, and system behavior.
• Convert experimental findings into practical engineering recommendations for Hardware, instrumentation, and system architecture.
• Conduct simulations (e.g., electrical, mechanical, thermal, and flow) to optimize stack operation and inform experimental design.
• Collaborate with engineers and scientists to bridge the gap between simulation and real-world performance.
• Collaborate with R&D, system engineering and Support scale-up from lab tests toward larger stack/system demonstrations by identifying technical risks, de-risking experiments, required sensors, control loops, and operational constraints.Prepare concise technical summaries, decision memos, requirement tables, and presentation materials for internal stakeholders, management, and external partners.

Qualifications:

Education:

• BSc in Physics, Mechanical Engineering, Chemical Engineering, Process Engineering, or a related field – Must.
• MSc/PhD – An advantage.

Experience & Skills:

• Strong background in experimental design, data analysis, and problem-solving in a technical setting.
• Hands-on experience designing, executing, and troubleshooting experiments in pilot-scale/industrial environments.
