ionysis is looking for a Senior Coating Engineer (f/m/d)

ionysis develops next-generation membrane electrode assemblies for electrochemical converters. Even if you would consider your skills in electrochemistry as limited, don’t stop reading just yet. Our excellent tech team takes care of that, while you might be the perfect fit to scale our innovations from the lab processes to a mass-scale feasible coating technology.  


As a recently founded and well-funded start-up based in beautiful Freiburg, we are looking for a senior coating engineer (f/m/d). You will play a key role in our tech team by bringing ionysis from prototyping towards a pilot-scale production environment.


What we do

To stop climate change and reach Net Zero, ionysis seeks to decarbonize mobility and industry with innovative electrochemical devices. We focus on the core of any electrochemical converter: the membrane electrode assembly (MEA). We develop and manufacture MEAs based on most performant fluorine-free materials for hydrogen technology, including fuel cells and electrolysers. As a spin-off from Hahn-Schickard and University of Freiburg, we combine scientific excellence with entrepreneurial spirit to bring our innovations to market and scale.

Your responsibilities

  • Installation and ramp-up of coating processes on our roll-to-roll production line for catalyst-coated membranes in a clean room

  • Maintenance of pilot-coating environment

  • Further development of advanced coating processes for new generations of catalyst-coated membranes

  • Fabrication and characterization of pilot-scaled CCM and MEA prototypes

  • Report and present your results in regular technical meetings

Your qualifications

  • Enthusiasm for fighting climate change and contributing to Net Zero

  • Strong team player and getting-things-done mentality

  • A technical education with profound lab experience (M.Sc., Ph.D. in engineering or related fields plus 2-5 years of relevant professional experience)

  • Substantial experience in coating technology and quality control for functional materials

  • Experience with working in a clean room environment is a plus

  • Ability, patience and endurance to perform similar experiments repetitively with the same high quality

  • Proficiency with common office software

  • Fluency in German and English

What we offer

  • Opportunity to join an early-stage well-financed start-up and shape the culture and processes

  • Opportunity to grow with the company in various roles depending on personal preferences and abilities

  • A young and diverse team with flat hierarchies, valuing collaboration with each other no matter your role at ionysis

  • A competitive salary package and 30 vacation days per year

  • Subsidized corporate fitness program (Hansefit) and lunch allowances

  • Virtual stock options for all new hires and for exceptional performance

  • A modern and well-equipped office and laboratories in Freiburg
