Job Description

About us

Ultra-Pure Water+ division of Ecolab is an engineering company specialized in ultrapure water (UPW) treatment systems.

Our Digital Innovation team is building a new capability in autonomous robotics, and we're hiring the first Robotics Software Engineer to join a small, senior team of software and computer-vision engineers.

Joining Ultra-Pure Water+ means being part of a global team of innovative and passionate professionals who are committed to preserving water, our planet's most critical resource. It also means combining our efforts and talents towards a more sustainable future – together.

The role is based in Witterswil, Solothurn (Basel Area), Switzerland, with good public transport connection (Tram 10) and free car parking.

What you'll do

• Design and build the software that controls a mobile robot platform operating autonomously in an industrial facility, integrating a commercial mobile base and sensors via vendor SDKs.
• Develop navigation, localization, and motion-planning capabilities (ROS/ROS2, Nav2, MoveIt2 or equivalent) for safe operation around people.
• Bring up and debug hardware end-to-end: mechanical, electrical, and software.
• Apply sound engineering judgment on robot safety for equipment operating near employees.
• Set the robotics architecture and practices the team will build on as it grows, and own delivery of the first working prototype.

What you bring

• 3+ years of robotics software engineering experience, including at least one robot taken from development into real-world pilot or production operation.
• Strong hands-on experience with ROS/ROS2 (or equivalent), including navigation and/or motion-planning stacks.
• Experience integrating commercial robot hardware via vendor SDKs, including bring-up and real-world debugging.
• Strong C++ and/or Python skills, with good engineering practices for building reliable systems around physical hardware.
• A pragmatic, hands-on, largely autonomous working style, comfortable being the only robotics specialist on the team.
• Fluent English, spoken and written.
• A valid Swiss, EU/EFTA, or cross-border commuter (G) work permit.

Nice to have

• Experience in computer vision (camera calibration, 3D reconstruction, hand-eye calibration).
• Background in industrial automation or manufacturing quality.
• Familiarity with mechanical CAD data.
• A degree in robotics, mechatronics, or a related engineering field.

What we offer

Real ownership of a new robotics capability from the ground up, in a small, experienced engineering team.
