Senior Full-Stack Developer - ShareGate Migrate [Web Experience]

Workleap is a Montreal-based tech company, founded in 2006. We're builders at heart, we make simple products that actually matter to the people who use them. We have two product lines: The Workleap Agent, our agentic HR platform that helps managers become better leaders, and ShareGate, the world's leading solution for Microsoft 365 migration and governance. More than 15,000 companies worldwide trust us to do exactly that. We're intentional about who joins us. If you're the kind of person who gets excited by a hard problem and wants to help shape what comes next, there's a place for you here.

So, what will your new role look like?

As Senior Full-Stack Developer, you'll play a key role in building the new ShareGate Migrate web application. With strong React and TypeScript expertise, you'll contribute across the full stack and collaborate closely with the product team to turn user needs into simple, well-crafted experiences. In this fast-moving squad, you'll thrive on quality, technical judgment, and continuous learning.

• →Ship full-stack features that meet quality, performance, and UX standards from the first milestones of the new web app.
• →Shape the team's technical choices (libraries, API patterns, code structure, test strategy) so each decision accelerates future delivery rather than adding weight.
• →Translate user needs into shipped experiences that solve the real problem, in tight partnership with Product and Design.
• →Integrate Microsoft APIs (Microsoft Graph, Azure AD / Entra ID, MSAL) reliably and securely so migration and authentication scenarios work without friction in production.
• →Anticipate technical risks before they block the team, and bring concrete solutions that keep delivery moving.
• →Raise the team's technical bar through code reviews and mentoring that make others grow, not just validate code.
• →Master AI-assisted development tools (such as Claude and GitHub Copilot) to deliver a level of quality and output that a solo dev couldn't achieve otherwise.

You'll join the Web Experience team, a cross-functional squad made up of developers, a Product Manager, and a Product Designer. The team is part of the ShareGate Migrate department, a collaborative network of teams with access to staff developers for technical guidance and cross-team alignment.

The team is starting an almost greenfield project, which means a strong culture of autonomy and collective decision-making from the very beginning. A senior developer is expected to have a visible impact not just on what gets shipped, but on how the team works and decides. AI-assisted development is a core part of how the team operates. Deep familiarity with these tools and the ability to get the most out of them are expected.

What are the next challenges awaiting your team?   

• Building the new ShareGate Migrate web application from scratch, laying technical foundations that hold up at scale.
• Bringing ShareGate's migration capabilities (sites, identities, content) into a fully web-based experience, with the performance and reliability constraints that entails.
• Establishing reusable technical patterns that will accelerate the development of each new feature over time.

What does the tech stack look like?

• TypeScript / React (frontend);
• C# / .NET (backend / API);
• Microsoft Graph API / Azure AD / MSAL;
• Azure (hosting, cloud services).

• 5 to 15 years of experience in software development, ideally in a product-oriented environment;
• Strong knowledge of frontend development with React (TypeScript);
• Experience in backend development with C# / .NET;
• Demonstrated ability to exercise strong technical judgment in a product context;
• Experience collaborating with product and design teams to deliver quality user experiences;
• Experience using AI tools in daily software development;
• Clear, direct communicator who can constructively challenge product decisions;
• Experience with Microsoft APIs (Microsoft Graph, Azure AD / Entra ID, MSAL) is an asset.
