Whether migrating from Google Workspace, file shares, Exchange Online, SharePoint On-Premises, or tenant-to-tenant, ShareGate gets the job done, without surprises. From cloud transformation to M&A integration, it keeps things just damn simple. ShareGate also helps organizations stay in control once their data is migrated.

It lays the groundwork for safe Microsoft Copilot deployment within organizations. ShareGate is developed by Halcyon Labs Technologies, a Montréal‑based software company. Your role You'll play a founding role on the Web Experience team, whose mission is to build a brand-new web application for ShareGate Migrate from scratch, making the Microsoft 365 migration experience even more accessible and intuitive, directly in the browser. This role exists now because we're starting from a blank page: you'll help define the technical foundations and user experience of a product that will have a direct impact on thousands of IT professionals around the world. Your impact: Ship full-stack features that meet the team's quality and UX standards from the first milestones of the new web app, built in close partnership with your Product Manager and Product Designer. Lay solid, lasting technical foundations from day one by contributing meaningfully to architecture decisions and the team's engineering practices. Integrate Microsoft APIs (Microsoft Graph, Azure AD / Entra ID, MSAL) reliably, so migration and authentication scenarios work without friction in production. Build a quality culture from the start by establishing testing practices that let the team ship with confidence. Grow the team's collective level through code reviews and knowledge sharing that make others better. Leverage AI coding tools (Claude, GitHub Copilot) to deliver a level of quality and output that goes beyond what a solo dev could achieve otherwise. Your team a) The team is starting a near-greenfield project: building the ShareGate Migrate web application almost from scratch, defining the technical foundations, architecture, and user experience. The next challenges: bringing new web features that complement the migration tool into a fully web-based experience, complementary to the existing desktop application, and establishing reusable technical patterns that will accelerate the development of each new feature over time. b) You'll join the Web Experience team, a cross-functional squad made up of developers, a Product Manager, and a Product Designer, part of the ShareGate Migrate department — a collaborative network of teams with access to staff developers for technical guidance and cross-team alignment. Because we're starting from a blank page, the culture is built on autonomy and collective decision-making from the very beginning: you won't be handed pre-built solutions. You'll be expected to form hypotheses, experiment quickly, and bring your findings back to the team. AI-assisted development is a core part of how the team works, not an afterthought. c) Tech stack: TypeScript and React on the front end, C# / .NET on the back end, relational or non-relational databases, and Microsoft API integration (Microsoft Graph, Azure AD / Entra ID, MSAL). What you'll bring 4+ years of experience delivering commercial software products with strong customer adoption; Proven experience building web applications with TypeScript and React, along with hands-on experience with relational or non-relational databases; Solid backend development skills in C# / .NET; Hands-on experience using AI coding tools (e.g. Claude, GitHub Copilot, or similar) as part of your day-to-day development workflow; Strong debugging and problem-solving skills, with the ability to tackle ambiguous and technically complex challenges; Clear, proactive communicator who takes ownership, operates with transparency, and keeps teammates informed; Bonus: experience with Microsoft APIs (Microsoft Graph, Azure AD / Entra ID, MSAL).
