Senior Ruby On Rails Developer Jobs in Milton, ON

Founded in 2019, Phoenix is building the most trusted telehealth platform in Canada, making specialist healthcare accessible to every Canadian, wherever they are. Our platform breaks down barriers to care, empowering patients to take control of their health with personalized treatment options and the guidance of licensed providers.
If you thrive where big ideas turn into real impact, you'll fit right in here. We're a team of creative problem-solvers who move deliberately and collaborate in person, because we think the best work happens that way. At Phoenix, you'll find autonomy over your work, people who care about each other's success, and a mission that's making healthcare better for Canadians.

We are seeking a Senior Full Stack Developer to help build a best-in-class consumer-grade digital experience. This role will contribute to architecture decisions, feature development, and execution across Phoenix & Raven's core patient experiences and care flows.

You will work on-site within an experienced product and engineering team, building directly on the patient side and physician side of our platform across web and mobile. Success in this role means owning complex problems end-to-end — from whiteboard to production — so that the platform scales with the business and the patients who depend on it. You're the kind of engineer who thinks in systems, writes clean code, and ships with care.

• Own features end-to-end — from architecture and design through testing, deployment, and iteration

• Build robust, reliable, and user-friendly experiences across Phoenix & Raven's patient-facing and physician-facing surfaces on web and mobile

• Participate in design and architecture discussions, bringing strong technical judgment to decisions that affect scale, stability, and patient safety

• Collaborate cross-functionally with product, clinical ops, and CX to move initiatives forward without bottlenecks

• Contribute to a codebase that the whole team can maintain, extend, and be proud of

• Support and evolve internal tooling that keeps patient operations, fulfillment, and clinical administration running smoothly

• Identify opportunities for AI-assisted automation across engineering workflows, internal tooling, and platform infrastructure

• 8+ years of professional programming experience, with 5+ years in Ruby on Rails.

• Comfort in at least one modern JavaScript front-end framework (ideally React).

• Experience with cloud platforms (ideally AWS) is a strong asset

• A track record of thoroughly testing and deploying your own code; you don't hand off and walk away.

• Strong systems thinking: you see edge cases, operational impact, and scalability tradeoffs before they become problems.

• Genuine curiosity; you actively experiment with AI-assisted development tools and bring that mindset into how you build and ship.

• You take pride in your craft but hold your solutions loosely: the best idea wins, regardless of who brought it to the whiteboard.

• Empathy for patients: you think seriously about the people on the other end of your code: what’s at stake for them, and the moments where reliability actually matters.

• A personal connection to improving the Canadian healthcare experience is a strong asset.

• A Rewarding Mission: Through our asynchronous care model, Phoenix is reimagining patient-centric care for Canadians across the country by making diagnoses and treatment delivery faster, more accessible, and completely discreet.

• Impact & Autonomy: You’ll work directly with passionate, experienced leaders who’ve seen the ups and downs of building a business and genuinely care about your growth. You won’t just execute — you’ll help shape the future of Phoenix and Raven.

• Collaborative On-Site Culture: Our teams work together in person, whether that's at our downtown Toronto HQ or our Richmond pharmacy. We come together on-site to build fast and push what's possible, and we love the quick feedback loops, spontaneous brainstorms, and actually knowing the people we work with. Bonus points if you're into the occasional office tournament or have strong opinions about the best lunch spot nearby.

• Competitive Pay, Real Benefits: Our compensation bands are backed by real market data, so offers are competitive and fair. Our benefits package includes standard healthcare coverage, a remote-first holiday season, and holistic wellbeing support — such as a wellbeing allowance and flexible additional time off to care for loved ones, support mental health, observe meaningful religious and cultural holidays, or when life just happens.
