Senior Fullstack Developer (C#/React), Migrate - ShareGate

Your role

As Senior Software Developer, you'll play a key role in building the new ShareGate Migrate web application. With strong React, C# 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.

Your impact:

• 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.

Your team

• 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.
• The next challenges awaiting the 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.
• The stack: TypeScript, React, and C# / .NET, with Microsoft APIs (Microsoft Graph, Azure AD / Entra ID, MSAL) and AI coding tools (Claude, GitHub Copilot) at the center of the day-to-day.

What you'll bring

• 5–15 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.
