Job Description:Senior Software Engineer - Full StackABOUT THE TEAM You'll be joining the Super-Awesome Fun Time (SAFT) Squad - the engineering team at the heart of Sun Life's IID Advisor & Firm Journey. Our mission: transform the digital experience for Independent Advisors and their firms on Suncentral and Advisor Hub, positioning Sun Life as the carrier of choice.
We gather user feedback, ship new features, and modernize legacy applications using up-to-date technologies - all while maintaining compliance and enabling advisors to deliver lifetime financial security to their clients. We move fast, build with purpose, and have a good time doing it.
WHAT YOU'LL DO As a Senior Engineer on this team, you'll be a strong individual contributor - someone who takes complex work end-to-end with minimal handholding, writes code the team can build on, and raises the bar through how you work day-to-day:- Design, build, and ship full-stack features on Suncentral and Advisor Hub - taking stories from refinement through to production with confidence
- Write clean, well-tested, maintainable code that integrates reliably with existing back-end services and front-end surfaces
- Contribute to technical discussions alongside the Tech Lead - sharing your perspective on approach, trade-offs, and implementation options
- Modernize legacy application components by replacing outdated patterns with current, maintainable solutions
- Collaborate with Agile team members (Journey Owner, Scrum Master, Tech Leads) to estimate work, flag risks early, and deliver within sprint commitments
- Apply analytical thinking to understand the downstream impact of your changes on infrastructure and system behaviour
- Occasionally support less experienced team members through code review feedback and informal pairing - as capacity allows
- Participate fully in agile ceremonies and contribute to a high-functioning, continuously improving team
WHAT YOU NEED TO SUCCEED Technical Skills- 5+ years of progressive full-stack development experience, including full SDLC and systems integration
- Strong Java / Spring / Spring Boot - the core of our back-end services
- API development proficiency: REST, OpenAPI, AJAX, SOAP; middleware and web hosting technologies
- Front-end fluency in React and React Router - component lifecycle, hooks, state management, SPA architecture, async rendering, client-side routing
- Strong JavaScript / TypeScript - ES6+ features including async/await, promises, destructuring, modules, arrow functions
- Solid HTML5 and CSS3; responsive design principles
- SQL expertise across relational databases (SQL Server, Oracle) and NoSQL (MongoDB)
- Hands-on with DevOps tooling: BitBucket, CDD, Jenkins
- Familiarity with C# / ASP.net is an asset
Soft Skills & Ways of Working- Self-directed - you ramp up quickly, take ownership, and deliver within fixed timeframes
- Clear communicator - you surface defects with reproducible steps and root-cause insight, not just symptoms
- Technically credible - your code, reviews, and problem-solving naturally raise the standard around you
- Collaborative - you understand and champion engineering best practices across the team
NICE TO HAVE - Experience in financial services or insurance technology
- Familiarity with Suncentral, Advisor Hub, or similar advisor-facing platforms
- Experience working in large-scale enterprise environments with compliance and audit requirements
SPECIAL REQUIREMENTS- Occasional travel between Sun Life locations (Toronto, Waterloo) may be required depending on work assignment
- Periodic weekend/after-hours work may be required to support project implementations and system upgrades
WHAT'S IN IT FOR YOU Sun Life is one of Canada's most established financial institutions - but this team doesn't feel like it. You'll join a squad with a genuine mandate to modernize, the space to do your best technical work, and direct visibility into how what you build impacts advisors and their clients.
- Work that matters - directly enabling advisors to deliver financial security to Canadians
- A collaborative, inclusive team culture (yes, the name is intentional - we take the work seriously, not ourselves)
- Flexible work style - Office, Virtual, or Hybrid depending on your role
- Competitive salary, bonus structure, and Sun Life benefits package

- Access to continuous learning, internal mobility, and engineering community of practice
