Our client, an established player in the financial services sector, is expanding its technology team and looking for an experienced .NET Full Stack Developer. This role suits someone who has built and shipped scalable enterprise systems end to end — comfortable moving between backend services and the frontend layer using the .NET stack. A distinguishing requirement here is practical, day-to-day fluency with AI-assisted development tooling such as GitHub Copilot or Microsoft Copilot (or comparable assistants), used to speed up coding, cut down on repetitive work, shorten debugging cycles, and generally streamline how software gets built.
What you'll be doing
- Architect, code, test, and maintain full stack applications on .NET / .NET Core / ASP.NET Core.
- Create and refine responsive interfaces with current frontend frameworks — Angular, React, JavaScript, and TypeScript.
- Build dependable APIs, microservices, and backend components tailored to financial applications.
- Partner with product owners, business analysts, architects, and QA to ship high-quality deliverables.
- Apply Copilot and other AI coding assistants across code generation, refactoring, documentation, debugging, and overall throughput.
- Produce clean, secure, maintainable, and clearly documented code aligned to established practices.
- Review peers' code and uphold coding standards and secure-development principles.
- Tune applications for performance, reliability, and scale.
- Work across SQL Server and other relational stores, contributing to data modeling, query tuning, and integration work.
- Take part in CI/CD pipelines, release processes, and broader DevOps practices.
- Meet the security, audit, and regulatory obligations that apply in a financial-services setting.
Requirements
What we're looking for
- Solid hands-on background across .NET Framework, .NET Core, ASP.NET MVC, and ASP.NET Core.
- Strong C# skills.
- Frontend experience React (this is a must), JavaScript, and TypeScript.
- A track record building and consuming REST APIs and web services.
- Deep familiarity with SQL Server and relational database work.
- Working experience with Entity Framework or other ORM tooling.
- Direct, practical use of GitHub Copilot, Microsoft Copilot, or similar AI coding assistants.
- Exposure to Azure or AWS cloud environments is a plus.
- Comfort with Git, CI/CD pipelines, and Agile/Scrum delivery.
- A firm grasp of software design fundamentals, debugging, and problem-solving.
- Understanding of secure coding, authentication and authorization, and data protection.
Benefits
What's on offer
- A global organization with a presence across dozens of offices in multiple countries, and scope for international mobility.
- 15 days (three weeks) of paid vacation, plus a further 10 personal days (a mix of floating and sick days).
- Full insurance coverage spanning medical, dental, vision, life, and long-term disability.
- A flexible hybrid working arrangement.
- RRSP participation with employer matching of up to 4%.
- Support for continuing education and professional certification.
- Company-wide access to Udemy for Business, with more than 5,000 curated courses available on demand.
- Mentorship from seasoned colleagues in the firm's financial-innovation and centre-of-excellence teams.
- Work on leading-edge engagements with top-tier banks, financial institutions, and insurers.
- A genuinely diverse, global, and easygoing team culture.
