Senior Full-Stack Developer (Ruby on Rails/React)

Full-time

The Phoenix

About Phoenix


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.

What we're looking for

We are looking for a senior full stack dev! Phoenix is a Y Combinator backed startup based in downtown Toronto. You’ll work closely with the cofounders to continue to build out the patient and physician side of our platform. We are looking for a passionate, mission-driven engineer who takes pride in the products they build. You're the type of dev who loves the whiteboard and figuring out streamlined solutions to complicated workflows.

Qualifications

  • Have 8+ years of professional programming experience

  • Have 5+ years of professional experience with Ruby on Rails

  • Are comfortable in at least one modern Javascript front-end framework (ideally React)

  • Creating software features that are robust, reliable, and user-friendly for both internal teams and our customers

  • Has experience thoroughly testing and deploying their own code

  • Participate in the design, architecture, and delivery of new features in a collaborative environment

  • Experience with Cloud Platforms is a nice to have (ideally AWS)

  • You are passionate about improving the Canadian healthcare experience and have a personal connection to the space

Why Work at Phoenix?

  • 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 In-Office Culture: Based in the heart of downtown Toronto, our HQ team comes together on-site five days a week to build fast and push what’s possible. We love the fast feedback loops, spontaneous brainstorms, and actually knowing the people we work with. Bonus points if you’re into the occasional foosball tournament or have strong opinions about the best lunch spot in the neighbourhood.

  • 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.

Thank you for your interest in joining the Phoenix team! While we are lucky to attract a high level of interest in each of our roles, only candidates selected for an interview will be contacted.
