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?

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

What you bring:

Bachelor’s degree in chemistry, engineering, or a related science

5+ years of hands‑on experience in sensor development, instrumentation, or related R&D;

Strong background in chemistry or electrochemistry, including experience with pH or electrochemical sensors

Experience designing and running experiments, testing instruments, and building test setups using lab equipment

Proficiency with data analysis tools such as Python or MATLAB

Robust attention to detail and solid documentation habits, with the ability to report findings clearly and concisely

A collaborative, organised approach and enthusiasm for taking on new challenges





Proficiency in written and spoken English

Nice to haves:

Master’s degree or PhD in a relevant field

Experience with ISFET, ion‑selective or potentiometric sensors

Experience developing calibration methods or transfer functions

Experience taking a sensor from prototype to production

Field deployment or water quality measurement experience

Salary range: $75,000 - $115,000

This role may be filled at the Sensor Engineer or Senior Sensor Engineer level. The final salary and job level will depend on your experience and qualifications. We know great talent shows up at different points in a career. Whether you’re earlier in your journey or bring senior‑level experience, we encourage you to apply.
