Team Lead – Application Foundations

At Croesus, we are at the forefront of digital transformation in the wealth management industry. As a provider of innovative, high-performance, and secure solutions, we offer a comprehensive range of tools, from portfolio management systems to application programming interfaces (APIs). Our mission is to empower wealth management professionals to reach new heights of productivity, strengthen their client relationships, and make informed decisions, while simplifying the management of assets under management.

With over 200 employees across our offices in Montreal, Toronto, and Geneva, we continue to expand our reach and deepen our impact on the community. 2026 marks a crucial stage in our growth trajectory. Faced with increased demand for our cutting-edge solutions, we are looking for a collaborative and results-driven recruitment expert to help grow the tech talent driving our future.

As team lead for the Application Foundations group, you will play a key role in the design and long-term reliability of the underlying mechanics of our systems. You will lead a talented team dedicated to building the core software platform and components used directly by our other internal development teams.

You will contribute your technical expertise by actively participating in the architecture vision and deliverables, while ensuring strategic alignment with the needs of internal client teams (a liaison / technical Product Owner role). You will be responsible for your team's performance, motivation, and development, as well as the continuous improvement of our engineering processes.

This role is part of a broader team restructuring effort: you will be responsible for defining the roadmap and putting in place the processes needed to mature the function.

This hybrid role will keep you connected to the technical realities on the ground (architecture, performance, scalability) while developing your people-management and coaching skills.
