Commissioning Engineer (Rail & Energy Systems)

At Sécheron Hasler Group, we bring over 140 years of Swiss engineering into modern railway and energy systems. Our technologies keep critical infrastructure running — and as a Commissioning Engineer, you are the one who makes it work in real life.

If you enjoy hands-on engineering, combining electrical systems and software, working directly with customers, and taking real responsibility, this role will push you forward quickly — experience helps, but what matters most is your ability to take ownership and solve real problems..

This role offers real independence in the field — you take over systems on-site, make decisions and get them operational. No two projects are the same, with changing locations, technologies and customers.
