Job Description

Insight Global is hiring a Principal Engineer to join a high‑impact digital engineering team supporting consumer‑facing technology initiatives within a large financial services environment. This is a contract‑to‑hire opportunity based in Toronto, focused on helping shape and deliver scalable digital solutions across online and potentially mobile platforms.

This role is ideal for a highly senior technical leader who operates at the intersection of architecture, design, and hands‑on engineering. The Principal Engineer will play a key role in defining technical direction, guiding engineering best practices, and contributing directly to development efforts within an up‑to‑date .NET environment.

This individual will function similarly to a Delivery Lead or Solution Architect, with a strong emphasis on both technical leadership and execution. Approximately 50% of the role will focus on design and architecture, with the remaining 50% dedicated to hands‑on coding, solution delivery, and mentoring junior developers. This person must be comfortable setting technical standards, solving complex engineering challenges, and leading by example through code.

The ideal candidate is someone who brings deep experience building consumer‑facing digital applications, thrives in cooperative Agile environments, and has the credibility and communication skills to influence both technical teams and business stakeholders.
