Sensor Engineer / Senior Sensor Engineer

- Location: Kanata, Ontario (onsite) - Reports to: Sensor Manager - Role status: Existing vacancy About RBR: Making waves since 1973 At RBR, we’ve been designing cutting-edge instruments to measure our blue planet for over 50 years. Built to withstand the harshest environments on Earth, our instruments are deployed from the ocean’s deepest trenches to the polar ice caps, capturing essential data on water temperature, salinity, pH, and more. This data empowers researchers in the global fight against climate change, and our technology supports groundbreaking science with partners like Fisheries and Oceans Canada, Woods Hole, the Scripps Institution, and the British Antarctic Survey. At RBR, we care deeply about our work, each other, the environment, and the global communities we serve. We value teamwork, continuous improvement, and having fun along the way. From weekly lunches to social events, we’re a crew that thrives on complex, exciting challenges that have a meaningful impact on the blue planet! Ready to make waves with us? Apply below! About the Role As a Sensor Engineer at RBR, you will specify, develop, and bring to life the sensor technology that measures the ocean environment. Working hands-on alongside specialists in firmware, electronics, mechanical, software, systems, and oceanography, you’ll solve challenging technical problems and build a deep understanding of the complete instrument. Your early focus will be on our chemical sensing work, particularly pH and electrochemical sensors, and over time you’ll support RBR’s full range of sensors. You’ll see your work through from the lab bench to instruments deployed by researchers around the world, making a tangible difference to ocean and climate science. What You’ll Do: - Develop and characterise chemical and electrochemical sensors, from requirements and specifications through testing and verification - Advance RBR’s production and in-development optical and chemical sensors, including turbidity, fluorescence, radiometry, photosynthetically active radiation (PAR), transmissometry, nitrate, pH, and dissolved oxygen - Develop and characterise pH and other electrochemical sensors, from requirements through testing and verification - Research and define next-generation sensor technology for RBR instruments - Design and run experiments to evaluate sensor performance and guide design decisions - Develop and refine calibration methods in partnership with our calibration lab team - Troubleshoot hardware and software issues to find root causes, providing first-line support to our production and assembly team and second-line support on customer issues - Collaborate with our multidisciplinary research and development (R&D) team and external partners on design and testing, balancing several projects at once - Create detailed project schedules, technical specifications, and prototype verification plans
