## Job description

## About ShareGate

[ShareGate](https://sharegate.com/) is the leading Microsoft 365 migration and governance platform, trusted by over 100,000 IT pros for its unmatched simplicity.

It offers the simplest, most reliable, and most affordable way to move business data to Microsoft 365.

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. Its powerful governance features let users assess environments, uncover issues, and apply fixes on the spot, so everything stays clean, secure, and optimized. It lays the groundwork for safe Microsoft Copilot deployment within organizations.

ShareGate is developed by Workleap Technologies, a Montréal‑based software company.

## 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.

What the job comes with

- Base salary: $125K–160K CAD. This range reflects our Canada-wide compensation scale. Final offers may be adjusted based on the candidate's region to align with local market conditions.
- Annual bonus program.
- LTIP program, share in Workleap's long-term growth.
- RRSP + Family health insurance + telemedicine + annual wellness budget.
- Flexible vacation policy.
- Remote work, with access to our Montreal office.
- In-person gatherings twice a year.
- Claude access, for everyone.

What drives us

We build software that sits at the center of how people experience work, every day, at every level.

We move fast. Priorities shift, decisions get made with the information we have, and we iterate. If you thrive on intensity and ambiguity doesn't slow you down, you'll feel right at home. We're builders. We do what it takes to move forward. AI is part of our toolkit. We use it to go faster and decide smarter, not to replace judgment.

If you want real impact and a place where your decisions matter, this is it.

## How we hire

Transparency is how we hire — for you as much as for us.

Here's how it works: a first call with a recruiter, then a virtual interview with the hiring manager. You'll then complete a take-home case study, followed by a meet with future colleagues to discuss it together. Depending on the role, the process may vary slightly — your recruiter will walk you through it on your first call.

We use AI to support certain steps of the process, but every hiring decision remains human.

We can't wait to meet you.

By applying, you confirm that you have read and agree to our [privacy policy](https://workleap.com/trust-center/privacy).
