Job description

Senior Electrochemist / Senior Electrochemical Engineer

On-site, Branford, CT (must be willing to relocate to the Bridgeport/Stamford area within one year of the start date)

About Oxylus Energy

Oxylus Energy is a climate-tech company building solutions that can scale. Our breakthrough electrochemical technology converts carbon dioxide into low-carbon fuels and chemicals, reducing the world's dependence on fossil fuels. We are a team of scientists, engineers, and problem solvers working to make that future real.

Job brief

As Senior Electrochemist / Senior Electrochemical Engineer, you will test the performance of membrane electrode assemblies (MEAs) for our CO₂ electrolyzers across a range of operating conditions. You will build a deep understanding of the operating and scientific principles that govern the electrochemical performance of our reactors, and design and run experiments that improve them.

Day to day, you will set up and manage electrochemical tests, ensure they consistently produce high-quality data, analyze the results, and report findings to project stakeholders. You will also play a key role in experimental design.

What You Will Do

• Perform electrochemical tests, then analyze and summarize the results. Common experiments include chronopotentiometry, EIS, accelerated stress testing, and cyclic voltammetry.
• Investigate failure mechanisms in CO₂ reduction systems.
• Manage, troubleshoot, and maintain electrochemical test stations.
• Use experimental data to guide future experimental plans.
• Communicate the status of test hardware and any issues that arise during experiments.
• Mentor junior members of the research team.
• Document procedures to build shared knowledge across the team.
• Prepare presentations and data analyses for the wider technical team.

Who You Are

• Academic background in chemistry, chemical engineering, physics, or materials science and engineering, with one of the following:
  • B.S./B.A. or equivalent degree with 6+ years of relevant experience.
  • M.S./M.A. or equivalent degree with 4+ years of relevant experience.
  • Ph.D. or equivalent degree with 2+ years of relevant experience working on electrolyzers, fuel cells, or batteries.
• Extensive hands‑on experience testing electrochemical devices, such as electrolyzers, fuel cells, flow batteries, or batteries, ideally in membrane electrode assembly (MEA) or zero‑gap cell formats.
• Hands‑on experience in chronopotentiometry, EIS, accelerated stress testing, polarization curves, and/or linear/cyclic/square‑wave voltammetry tests.
• A strong command of electrochemical fundamentals, including reaction kinetics and mass transport processes.
• Hands‑on experience operating and troubleshooting test stations, including potentiostats or power supplies, mass flow controllers, humidification systems, and pressure control.
• Experience designing experimental plans, including design‑of‑experiments (DOE) studies, and drawing sound conclusions from complex or imperfect data.
• A track record of independently leading research or development projects from concept to results, demonstrated, for example, through publications, patents, or delivered products.
• Experience writing standard test protocols and training others to follow them.
• A strong commitment to lab safety, including working with pressurized systems and hazardous gases such as CO.
• Highly attentive to detail, with strong organizational skills.
• Outstanding written, verbal, and presentation skills.
• Able to lift up to 20 lb, with or without reasonable accommodation, while assembling larger-format cells.

Salary

USD 115,000–135,000 per year base salary, commensurate with experience, education, and skills.

Benefits

• Competitive salary
• Medical, dental, and vision coverage
• Paid sick days and vacation
• 401k match
• A diverse and inclusive work environment
