Senior Software Developer

About R :
Making waves since 1973

At R , 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 R , 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!

As the Senior Software Developer
, you’ll be joining a small, collaborative software team at R . Your primary focus will be Ruskin, R ’s flagship cross‑platform desktop application (Mac and Windows) that connects to, configures, and deploys our full instrument lineup, and integrates with other internal systems to keep everything in one place. A secondary focus is our calibration software ecosystem, including a standalone calibration application currently being spun out of Ruskin into its own product.

You’ll work closely with every engineering discipline at R , which means your code has a direct impact on the physical instruments our customers rely on. This is a full‑stack role with real breadth: from UI and databases through to low‑level instrument communications and release engineering. You’ll own 3–4 projects at a time, seeing them from requirements through to delivery, and interfacing directly with other teams to make it happen.

This is a fast‑moving environment where priorities shift by the hour, the right person finds that energising, not frustrating.

• Evolve Ruskin’s sophisticated multi‑layered Java‑based desktop platform and design scalable systems for processing sensor data
• Drive the software roadmap and long‑term architectural vision
• Contribute to and improve our CI/CD pipelines, build system, and release planning
• Build and improve automated testing and Dev Ops processes, everyone on this team chips in here
• Develop robust communication protocols between Ruskin and R ’s instrument lineup
• Optimise database and storage interactions
• Architect and maintain instrument communication frameworks
• Build and maintain calibration software systems and REST APIs using Spring/Spring Boot
• Develop and improve our standalone calibration application (currently being spun out of Ruskin)
• Integrate calibration workflows with QA, manufacturing, and lab operations
• Design intuitive UIs for both researchers (customers) and R ’s internal Calibration team
• Balance functionality with usability for mission‑critical desktop applications
• Bring a UI/UX lens to design discussions, we want someone who thinks about the end user, not just the code
• Provide internal support to Engineering, Production, and Calibration teams
• Action support tickets from external users and the global oceanographic community
• Review and test code changes from other developers, QA is a shared responsibility, not a separate function
• Provide technical mentorship and conduct design and code reviews
• Support researchers deploying instruments worldwide and contribute to open science
• Provide developer‑level support to the global oceanographic community
• Ensure data accuracy through reliable, well‑integrated calibration systems

• Hands‑on Java development experience (J2SE, J2ME, or J2EE) – you’ve built real software and can show it
• Experience developing desktop applications (Windows and/or macOS) – this is not a SaaS or cloud role
• Comfort spanning the full stack: UI through to backend, data, and external system integrations
• A track record of contributing to QA and testing – not handing it off to someone else
• Some exposure to Dev Ops practices and build automation; you’ve created or improved automated…
