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 theSenior Software Developer , you’ll be joining a small, collaborative software team at RBR. Your primary focus will be Ruskin, RBR’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 RBR, 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.What you’ll build:Evolve Ruskin’s sophisticated multi‑layered Java‑based desktop platform and design scalable systems for processing sensor dataDrive the software roadmap and long‑term architectural visionContribute to and improve our CI/CD pipelines, build system, and release planningBuild and improve automated testing and DevOps processes, everyone on this team chips in hereDevelop robust communication protocols between Ruskin and RBR’s instrument lineupOptimise database and storage interactionsArchitect and maintain instrument communication frameworksCalibration software & APIsBuild and maintain calibration software systems and REST APIs using Spring/Spring BootDevelop and improve our standalone calibration application (currently being spun out of Ruskin)Integrate calibration workflows with QA, manufacturing, and lab operationsDesign intuitive UIs for both researchers (customers) and RBR’s internal Calibration teamBalance functionality with usability for mission‑critical desktop applicationsBring a UI/UX lens to design discussions, we want someone who thinks about the end user, not just the codeProvide internal support to Engineering, Production, and Calibration teamsAction support tickets from external users and the global oceanographic communityReview and test code changes from other developers, QA is a shared responsibility, not a separate functionProvide technical mentorship and conduct design and code reviewsSupport researchers deploying instruments worldwide and contribute to open scienceProvide developer‑level support to the global oceanographic communityEnsure data accuracy through reliable, well‑integrated calibration systemsWhat you bring:Hands‑on Java development experience (J2SE, J2ME, or J2EE) – you’ve built real software and can show itExperience developing desktop applications (Windows and/or macOS) – this is not a SaaS or cloud roleComfort spanning the full stack: UI through to backend, data, and external system integrationsA track record of contributing to QA and testing – not handing it off to someone elseSome exposure to DevOps practices and build automation; you’ve created or improved automated processesStrong OOP fundamentals, design patterns, and cross‑platform development experienceNice to haves:UI frameworks: SWT, Swing, or JavaFX for desktop; HTML and REST for where we’re headedSQLite for database experience; Spring or Spring Boot signals awareness of our modern Java directionUI/UX sensibility — even informal experience thinking about usability and designFamiliarity with AI development tools (GitHub Copilot, ChatGPT, Claude, Gemini, etc.) or a genuine interest in working with them — this is a real differentiator for usExperience architecting complex, multi‑tiered systems integrating hardware, databases, APIs, and user interfacesSalary range: $120,000–$155,000 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. Depending on fit, the role level may shift accordingly.Why you’ll love working at RBR20 days of vacation, plus a company‑wide holiday shutdown and paid sick daysBenefits from day 1 & RRSP contribution matchingAnnual fitness reimbursement programWeekly lunches (on us!)Team events and social activitiesCollaborative, supportive work environmentDirect impact on climate science and ocean researchAt RBR, we celebrate and support diversity in our workplace.
