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.
