We’re looking for our next Principal Software Engineer. Could It Be You?

The Principal Software Engineer at Questrade is a strategic technical leader and an "out-of-the-box" thinker. In this role, you aren't just completing tickets — you are a force multiplier who levels up the engineering team by sharing knowledge and enabling others to do their best work within the squad's domain.
In addition to being a capable delivery practitioner, you will lead the research and architecture for complex systems, ensuring our technical direction aligns with business needs while establishing the standards and best practices that our teams live by. You are proactive, identifying friction in our processes — like improving local testing or observability — and building solutions that benefit everyone.

• Product Focused Delivery Excellence: Balance technical leadership with active delivery — this role ships code, not just strategy. Expected to be a consistent hands-on contributor to the team's output.
• Technical Strategy: Collaborate with architects and leads to design the approach for software solutions within your domain, including technology direction and architectural decisions scoped to your systems.
• Indirect Leadership: Focus on "leveling up" other engineers through influence rather than direct reporting, helping them solve complex problems independently.
• Architectural Excellence: Ensure consistency of design across services and modules, making sure individual components work together as a cohesive system.
• Modern Enablement: Champion the adoption of AI-powered tools like Claude AI and Cursor to remove development friction and improve the team's day-to-day engineering experience.
• Operational Excellence: Define and implement standards for Scalability, Security, Logging, and Performance Monitoring to ensure our systems are production-ready.
• Technical Deep-Dives: Troubleshoot and optimize highly complex issues within the domain, serving as the team's go-to reference on the toughest technical challenges.
• Documentation & Vision: Author clear design proposals and technical strategies that translate business requirements into specific architectural solutions within your area of ownership.
• Quality Mentorship: Foster a culture of excellence through technical guidance, complex code reviews, and support on high-complexity test plans.

So are YOU our next Senior AI Engineer? You are if you…

• Experience: 8+ years of software development experience with a track record of leading highly complex technical initiatives.
• Education: Bachelor's or Master's degree in Computer Science, Systems Engineering, or equivalent hands-on experience.
• Expert Stack Knowledge: You have deep, production-grade experience in C#, Minimal APIs, React Native and Angular, with a strong grasp of Service Oriented Architecture (SOA).
• Pattern Mastery: You have a solid command of SOLID principles, integration design patterns, and REST-ful/SOAP-based services.
• AI-Powered Development: You are comfortable using or eager to adopt AI coding tools like Claude AI and Cursor as part of your daily workflow.
• Leadership Style: You believe in "leadership by influence" and are passionate about helping engineers grow their technical skills.
• Problem Solver: You have a track record of identifying bottlenecks within a system or sub-system and taking the initiative to fix them.
• Communication: You can explain complex architectural concepts to both technical and non-technical stakeholders with clarity and ease.

Additional Kudos If You…

• Experience with Financial Services application development
• Experience with API Management and Middleware systems.
• Familiarity with driving technical decisions within a squad or across closely related teams.
• A habit of staying current on industry trends and proactively sharing that knowledge with your peers.

Additional Information…

• This role requires three days of in-office presence per week for Greater Toronto Area (GTA) residents. For candidates residing outside the GTA, a remote workplace arrangement is available.

Compensation Information:

• The final package will be commensurate with experience, skills, and geographic location (Canada).
• Includes a comprehensive benefits plan and a competitive incentive (bonus) program.
