Full job description

At CGI, you’ll play a pivotal role in building and sustaining secure, high-impact applications that underpin critical services for our clients. As a C# Developer, you’ll contribute to the full application lifecycle, combining hands-on development with 4th line support to ensure resilient, high-performing systems. Working within a collaborative, ownership-driven culture, you’ll help deliver measurable outcomes, strengthen long-term client relationships, and shape solutions that make a real difference in a highly secure environment.

CGI was recognised in the Sunday Times Best Places to Work List 2025 and has been named a UK ‘Best Employer’ by the Financial Times. We offer a competitive salary, excellent pension, private healthcare, plus a share scheme (3.5% + 3.5% matching) which makes you a CGI Partner not just an employee. We are committed to inclusivity, building a genuinely diverse community of tech talent and inspiring everyone to pursue careers in our sector, including our Armed Forces, and are proud to hold a Gold Award in recognition of our support of the Armed Forces Corporate Covenant. Join us and you’ll be part of an open, friendly community of experts. We’ll train and support you in taking your career wherever you want it to go.

Due to the secure nature of the programme, you will need to hold UK Security Clearance or be eligible to go through this clearance. This is a full-time onsite position based in our Reading office, five days per week. UK sole nationality is required.

Your future duties and responsibilities

In this role, you will develop, maintain, and support a secure application using C#, ASP.NET, and SQL Server, taking ownership of both new functionality and the stability of a mature system. You’ll work closely with colleagues and, where appropriate, directly with the client, building trust through clear technical communication and reliable delivery. Supported by experienced peers, you’ll grow into a trusted technical authority and subject matter expert for the customer environment.

You will contribute to continuous improvement by applying strong software development practices, diagnosing complex issues, and ensuring solutions meet the highest security and quality standards.

Key responsibilities include:

Develop & enhance secure applications using C# and ASP.NET

Support & resolve complex 4th line application issues

Analyse, debug, and improve mature production systems

Manage code and work items using Azure DevOps

Collaborate with stakeholders and communicate technical solutions clearly

Contribute to best practice within a highly secure delivery environment

Required qualifications to be successful in this role

You will bring solid experience in Microsoft-based application development, with the ability to support and enhance secure, business-critical systems. You should be comfortable working with established codebases, applying strong debugging skills, and communicating effectively with both technical and non-technical stakeholders.

Essential qualifications:

Strong experience with C# and ASP.NET

Proven experience using SQL Server

Familiarity with the Microsoft development toolchain

Good understanding of modern software development practices

Experience supporting and debugging mature applications

Ability to work effectively in a secure environment

Clear and confident technical communication skills
