Application Development Manager, Trading Platforms, Vice President

Citi•Mississauga, ON

12d•CA$120,800 - CA$170,800•Onsite

About The Position

This role is for an engineer at heart who has grown into a leader. The Application Development Manager will stay close to the code and actively participate in design, review, and technical problem-solving alongside the team. This individual will think AI-first by actively seeking opportunities to apply AI and GenAI to engineering and operational challenges, not just product features. They will own outcomes by taking full accountability for platform quality, reliability, and delivery commitments. The ideal candidate thrives in complexity, is comfortable navigating the technical and operational complexity of mission-critical financial systems, and raises the bar by consistently pushing for higher engineering standards, better test coverage, cleaner architecture, and more resilient systems. They embrace AI pragmatically by identifying high-value opportunities to apply AI/ML to real platform problems, without losing sight of engineering fundamentals, and inspire curiosity by creating an environment where engineers are excited to learn, experiment, and grow with AI.
