Fuel Cell Process Engineer

About the role

PowerUP Energy Technologies, a hydrogen technology startup based in Estonia, is looking for a Fuel Cell Process Engineer on a full-time, hybrid basis. You will help design, develop and optimise fuel cell power systems and work with European space agency projects, collaborating with a multidisciplinary team of engineers and scientists to meet client performance, reliability and cost targets. Experience in PEMFC, hydrogen or electrolyser is beneficial.

Key responsibilities

• Lead the design, calculation and development of complete fuel cell systems or electrochemical compressors, integrating fluid components, power electronics and thermal management subsystems.
• Build fuel cell and electrochemical compressor models in tools such as Matlab/Simulink/LabVIEW to analyse performance, find bottlenecks and improve efficiency.
• Evaluate and select components (stacks, compressors, balance of plant items) from suppliers and design the architecture of complete systems.
• Design and run test plans to validate performance, durability and safety, then analyse test data and modify designs accordingly.
• Troubleshoot system-level issues arising during testing or operation.

Required profile

• Masters or PhD in Chemical, Mechanical or Electrical Engineering or a related field.
• Working knowledge of fuel cells, electrolyzers, electrochemical compressors, batteries or other electrochemical systems.
• Experience in flowchart system design and flow/thermal calculations.
• Fluent written and spoken English; willingness to relocate to Tallinn is an advantage.

Required skills

• Proficiency in MATLAB, LabVIEW or Simulink.
• Understanding of control system engineering principles and design fundamentals.
• Ability to collate data and present clear results verbally and in reports.
• Advantageous: familiarity with fuel cell controls and algorithms, and hands-on experience with PEMFC, SOFC, alkaline systems, heat exchangers and electrolyzers.

What we offer

• A chance to join a pioneering tech startup and contribute to sustainable energy technology.
• A collaborative, friendly multi-national team with opportunities for professional growth.
