Sign up with Clera and we'll reach out the moment a role actually fits you — no more spraying applications into the void.
Lead the development of innovative web and mobile applications while providing technical leadership and mentorship to a team of developers. Collaborate with architects to design scalable, secure architectures and participate in agile development processes.
Requires proven experience in full stack JavaScript development with a strong focus on Node.js and modern front-end frameworks. Candidates must be eligible for UK Security Check (SC) clearance, requiring continuous UK residence for the last 5 years.
We are seeking a highly skilled and experienced Senior Full Stack JavaScript Developer to join our Experience Engineering team. In this role, you will lead the development of innovative web and mobile applications, ensuring high performance, scalability, and maintainability. You will work closely with cross-functional teams to deliver engaging solutions that meet our clients' needs.
Our team is at the forefront of developing cutting-edge technologies and solutions that ensure national security and defence. You will have the opportunity to work on and lead groundbreaking projects that involve the latest advancements in artificial intelligence, cybersecurity, and autonomous systems. Our commitment to innovation means you will be part of a team that is constantly pushing the boundaries of what is possible, making a real impact on the future of defence.
Hybrid working: The places that you work from day to day will vary according to your role, your needs, and those of the business; it will be a blend of Company offices, client sites, and your home; noting that you will be unable to work at home 100% of the time.
If you are successfully offered this position, you will go through a series of pre-employment checks, including:
identity, nationality (single or dual) or immigration status, employment history going back 3 continuous years, and unspent criminal record check (known as Disclosure and Barring Service)
• Provide technical leadership and mentorship to a team of developers, guiding them through collaboration, innovation and facilitation to ensure best practices and high-quality code.
• Design, develop, and maintain both front-end components of web and mobile applications using React, Angular, TypeScript, Bootstrap 5, HTML, CSS
• Apply Test Driven Development (TDD) practices using tools such as Karma to ensure robust and reliable code.
• Leverage AI-augmented development tools like GitHub Copilot to accelerate coding, improve consistency, and reduce boilerplate.
• Collaborate with architects and other developers to design robust, scalable, and secure architectures for new projects and enhancements to existing systems.
• Lead and participate in agile development processes, including sprint planning, daily stand-ups, and retrospectives.
You can bring your whole self to work. At Capgemini, stiving for equity, diversity and inclusion is part of everyday life, and will be part of your working reality. We have built an inclusive and welcoming environment, for everyone.
• Design, develop, and maintain both front-end and back-end components of web and mobile applications using JavaScript, Node.js, and modern frameworks and libraries such as React, Angular, or Vue.js.
• Proven experience in full stack JavaScript development, with a strong focus on Node.js and server-side development.
• Experience using AI-assisted development tools (e.g. GitHub Copilot) to enhance productivity and code quality.
• Experience of at least one leading Node framework (Express.js, Nest.js, Hapi.js)
• Expertise in at least one modern front-end framework (Nest.js, Remix.js).
• A track record in a lead or senior developer role, with experience of mentoring and guiding development teams.
To be successfully appointed to this role, it is a requirement to obtain Security Check (SC) clearance.
To obtain SC clearance, the successful applicant must have resided continuously within the United Kingdom for the last 5 years, along with other criteria and requirements.
Throughout the recruitment process, you will be asked questions about your security clearance eligibility such as, but not limited to, country of residence and nationality.
Some posts are restricted to sole UK Nationals for security reasons; therefore, you may be asked about your citizenship in the application process.
You will be empowered to explore, innovate, and progress. You will benefit from Capgemini’s ‘learning for life’ mindset, meaning you will have countless training and development opportunities from thinktanks to hackathons, and access to 250,000 courses with numerous external certifications from AWS, Microsoft, Harvard ManageMentor, Cybersecurity qualifications and much more.
You’ll be bringing your unique skills and perspectives to the team, inspiring and taking inspiration from your teammates as you unlock value in everything you do. You’ll be joining a professional community of experts, who have got your back and will support you, every step of the way.
You will be encouraged to have a positive work-life balance. Our hybrid-first way of working means we embed hybrid working in all that we do and make flexible working arrangements the day-to-day reality for our people. All UK employees are eligible to request flexible working arrangements.
