About The Position

Questrade Financial Group (QFG) is seeking a Principal Software Engineer to join their diverse, inclusive, and hybrid workplace. This role is for a strategic technical leader and an "out-of-the-box" thinker who acts as a force multiplier, leveling up the engineering team through knowledge sharing and enabling others. The ideal candidate will lead research and architecture for complex systems, ensuring technical direction aligns with business needs and establishing standards and best practices. This role involves active delivery, shipping code, and being a consistent hands-on contributor. Responsibilities include collaborating with architects and leads on software solutions, influencing engineers to solve complex problems, ensuring design consistency across services, championing AI-powered tools, defining operational standards for scalability, security, logging, and performance monitoring, troubleshooting complex issues, authoring design proposals, and providing technical guidance through code reviews and test plan support.

Requirements

• 8+ years of software development experience with a track record of leading highly complex technical initiatives.
• Bachelor's or Master's degree in Computer Science, Systems Engineering, or equivalent hands-on experience.
• Deep, production-grade experience in C#, Minimal APIs, React Native and Angular, with a strong grasp of Service Oriented Architecture (SOA).
• Solid command of SOLID principles, integration design patterns, and REST-ful/SOAP-based services.
• Comfortable using or eager to adopt AI coding tools like Claude AI and Cursor as part of your daily workflow.
• Belief in "leadership by influence" and passion for helping engineers grow their technical skills.
• Track record of identifying bottlenecks within a system or sub-system and taking the initiative to fix them.
• Ability to explain complex architectural concepts to both technical and non-technical stakeholders with clarity and ease.

Nice To Haves

• 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.

Responsibilities

• 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.
• 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.
• Focus on "leveling up" other engineers through influence rather than direct reporting, helping them solve complex problems independently.
• Ensure consistency of design across services and modules, making sure individual components work together as a cohesive system.
• 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.
• Define and implement standards for Scalability, Security, Logging, and Performance Monitoring to ensure our systems are production-ready.
• Troubleshoot and optimize highly complex issues within the domain, serving as the team's go-to reference on the toughest technical challenges.
• Author clear design proposals and technical strategies that translate business requirements into specific architectural solutions within your area of ownership.
• Foster a culture of excellence through technical guidance, complex code reviews, and support on high-complexity test plans.

Benefits

• Health & wellbeing resources and programs.
• Paid vacation, personal, and sick days for work-life balance.
• Competitive compensation and benefits packages.
• Work-life balance in a hybrid environment with at least 3 days in office.
• Career growth and development opportunities.
• Community contribution opportunities to support various causes.
• Inclusive environment working with diverse team members in a collaborative setting.
