About the Job:

This is a hands-on, execution-heavy role within Sun Life's startup-style innovation team focused on rapidly designing, building, and scaling transformative digital products- including an agentic AI platform and new client experience solutions. Reporting to the Director of Engineering, In-House Accelerator, you will own the full product lifecycle from concept to launch, writing production code, making pragmatic architecture decisions, and shipping working software quickly in a regulated environment. This role demands both technical excellence and entrepreneurial ownership, combining the agility of a startup with the resources and impact of a global enterprise. You will build products from zero, deliver them to users, and own the outcomes of your work.

What You’ll Do?
 

Own products end‑to‑end

• Use AI-assisted development and coding agents to accelerate prototyping, implementation, testing, debugging, and code review without compromising engineering quality.

• Make pragmatic technical decisions that balance speed, quality, scalability, and business impact.

• Own outcomes. If something isn’t working, you fix it.

Build fast, learn faster

• Prototype quickly, launch MVPs, run experiments, and validate ideas with real users.

• Instrument everything, gather feedback, and iterate based on data.

Lead by building

• Write production‑quality code daily while guiding the technical direction of the team.

• Establish lightweight architecture and engineering practices that enable speed without chaos.

• Provide clear technical leadership through code reviews, design discussions, and mentorship.

Collaborate across disciplines

• Work directly with product managers, designers, and business stakeholders to turn ambiguous problems into working software.

• Clearly communicate trade‑offs, risks, and timelines to both technical and non‑technical audiences.

Shape the future

• Champion modern engineering practices, tools, and technologies that give us a competitive edge.

• Build reusable components and technical foundations that accelerate future products.
   

What You Bring?
 

Engineering depth & versatility

• 7–10 years of hands-on engineering experience, with recent, demonstrable coding work.

• Demonstrated experience using AI-assisted development tools as part of day-to-day software development, with strong practices for prompting, code review, testing, security, and validating AI-generated code.

• Experience designing and building microservices, APIs, and distributed systems that scale.

Product mindset

• You think in terms of user value, not just technical elegance.

• You’re comfortable making decisions with incomplete information and adjusting as you learn.

• You bias toward action, experimentation, and learning over perfection.

Cloud & delivery fluency

• Hands‑on experience deploying and operating software in the cloud (AWS, Azure).

• Comfortable with CI/CD, containers, and shipping code to production frequently.

• A solid handle on performance, observability, security, and resilient system design.

Leadership & communication

• Proven ability to influence technical direction without relying on hierarchy.

• Experience mentoring engineers and raising the bar through example.

• Strong communication skills. You can explain complex systems simply and persuasively.
   

Nice to Have:

• Experience in startups, accelerators, or innovation labs.

• Experience with AI/ML systems → building with LLMs, prompt engineering, or agentic architectures.  

Why This Role?

• High-Impact Work: Build products that directly shape Sun Life's future, with your code reaching real users quickly.

• Leadership Opportunity: Lead technical direction, mentor others, and shape the engineering culture of a growing team.

• Autonomy and Ownership: Make decisions, drive solutions, and see the direct impact of your work.

• Learn and Grow Fast: Exposure to new technologies, business problems, and the full product lifecycle in a compressed timeframe.
