Robotics Software Engineer

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.

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.

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.

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