Full job description

At CGI, you'll play a key role in delivering secure, high-impact digital solutions that support critical UK Defence operations.

As a Software Engineer (Web Portal Developer), you will help develop, maintain and enhance customer-facing portal services that enable the delivery of mission-critical information and data products.

Working alongside military personnel, civil servants and technical specialists at RAF Waddington near Lincoln, you will contribute to innovative solutions that support national security while developing your expertise in a collaborative, supportive environment where your ideas, ownership and technical growth are valued.

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 hybrid position requiring attendance to the Waddington Site Nr Lincoln when required.

Your future duties and responsibilities

In this role, you will support the development, configuration and maintenance of secure web portal solutions used within a Defence environment. Working closely with customers, data analysts and development teams, you will help ensure the reliable delivery of portal services and data products that support operational decision-making. You'll have the opportunity to take ownership of technical tasks, contribute to agile development activities and support the continuous improvement of systems and processes.

You will also play a key role in portal administration, product configuration and deployment activities across multiple environments. Using your technical expertise and problem-solving skills, you will help investigate issues, support integrations and contribute to the successful delivery of customer requirements in a secure and collaborative setting.

Key responsibilities:

Develop & Maintain secure customer-facing web portal solutions
Configure & Support document hosting areas and portal environments
Collaborate & Engage with customers, stakeholders and technical teams
Investigate & Resolve portal faults and configuration issues
Create & Deliver standalone portal installation and update packages
Support & Enhance agile software development activities and sprint delivery
Configure & Test customer data products and associated datasets
Deploy & Integrate solutions across multiple environments
Perform & Validate cross-system verification and consistency checks
Contribute & Improve portal administration processes and technical documentation

Required qualifications to be successful in this role

To succeed in this role, you should have a foundation in software engineering, web technologies or portal-based applications, combined with strong communication and problem-solving skills. You will be comfortable working in a collaborative team environment, engaging with customers and stakeholders, and supporting technical solutions throughout their lifecycle. Experience within Defence is beneficial but not essential, as training and support will be provided.

Essential qualifications and experience:

Experience supporting, developing or administering web-based applications or portals
Understanding of software development lifecycle principles and agile delivery approaches
Knowledge of web technologies, application deployment and system configuration
Experience troubleshooting and resolving technical issues
Strong communication and stakeholder engagement skills
Ability to manage multiple priorities and work effectively in a structured environment
Understanding of configuration management and software release processes
Exposure to automation, scripting or DevOps practices would be advantageous
Familiarity with SAFe Agile methodologies is desirable
Defence, government or secure environment experience is desirable but not essential
Eligible and willing to obtain and maintain UK Security Clearance (SC)

Together, as owners, let’s turn meaningful insights into action.

Life at CGI is rooted in ownership, teamwork, respect and belonging. Here, you’ll reach your full potential because…

You are invited to be an owner from day 1 as we work together to bring our Dream to life. That’s why we call ourselves CGI Partners rather than employees. We benefit from our collective success and actively shape our company’s strategy and direction.

Your work creates value. You’ll develop innovative solutions and build relationships with teammates and clients while accessing global capabilities to scale your ideas, embrace new opportunities, and benefit from expansive industry and technology expertise.

You’ll shape your career by joining a company built to grow and last. You’ll be supported by leaders who care about your health and well-being and provide you with opportunities to deepen your skills and broaden your horizons.

Come join our team—one of the largest IT and business consulting services firms in the world.
