Our client is one of Canada's largest member-owned financial cooperatives, founded with a mission to make financial services more accessible and equitable. Today, the organization serves ~600,000 members, manages ~$42 billion in assets, and employs approximately ~2,700 people. Unlike traditional banks, our client is owned by its members rather than external shareholders, with a longstanding commitment to reinvesting in the communities it serves.

In a technology industry often characterized by venture-backed growth, shareholder returns, and the pursuit of liquidity events, our client offers a distinctly different proposition. As a member-owned financial cooperative, the organization is accountable to the members it serves rather than external investors, and directs 30% of its annual net income back to members and communities. Its commitment to social responsibility extends to its own workforce to whom they offer a defined-contribution pension, and has earned repeated recognition among Canada’s top employers. For technologists, this creates an uncommon intersection of meaningful work, organizational stability, and technical ambition: the opportunity to modernize the infrastructure of a major financial institution whose success is measured not simply by commercial performance, but by the financial well-being of its members and the communities it serves.

The organization is undergoing a significant transformation and investing in digital banking, payments modernization, and the technology infrastructure needed to support its next chapter of growth. Following a return to profitability and a period of renewed investment, our client is simultaneously modernizing its technology landscape while continuing to operate the complex systems that underpin its existing business.





Integration engineering is central to this transformation. Our client operates a heterogeneous technology environment comprising a Temenos core banking platform, .
NET-based services, MuleSoft integrations, and a growing Microsoft Azure footprint. Historically, much of its .
NET integration infrastructure has operated on-premises, while a substantial portion of its cloud-based integrations have focused on the integration of MuleSoft. The organization is now building a new Azure-native integration platform, with initial delivery targeted for FY2027, and is investing in the engineering capabilities needed to support this evolution.

As a Senior Integration Engineer, you'll join the Integration Platform team and report to the Senior Manager of this team. You'll play a hands‑on role in designing and developing this emerging Azure integration architecture, bringing the cloud engineering expertise needed to complement the team's established .
NET capabilities. The prospect extends beyond individual contribution: you'll help establish architectural patterns, provide technical direction to small groups of engineers, and collaborate with infrastructure and other engineering teams to bring new services into production.

Key responsibilities

- Integration architecture & engineering: Design, build, and maintain enterprise integrations and backend services using C#, .




NET, and Azure Integration Services
