Overview:As a Lead Full Stack Developer in the IP Development team, you will take end-to-end ownership of technical delivery within your squad, ensuring high-quality, scalable solutions that align with both product goals and engineering standards. You will play a key role in architectural, tooling, and implementation decisions, working closely with the Principal Developer, other Lead Developers, and Engineering Managers to ensure your squad’s work contributes to a consistent and scalable wider strategy. You’ll also collaborate with Product Managers, UX Designers, and Business Analysts to turn complex requirements into robust, maintainable software, while fostering a culture of learning by mentoring developers and driving continuous improvement.Our core technology stack is built with TypeScript, using React on the front end and NestJS on the back end, with services deployed via containers to Microsoft Azure. Experience with AI technologies—both in leveraging AI-assisted development tools and in building AI-powered features into business applications—is increasingly important. Responsibilities:
  • Lead and mentor your squad in full stack development, fostering technical excellence and continuous learning.
  • Own technical delivery within your squad while collaborating with the Principal Developer, other Lead Developers, and Engineering Managers on architecture, tooling, and wider engineering strategy.
  • Develop and maintain server-side logic and user-facing features, ensuring applications are high-quality, scalable, and secure.
  • Work with Product Managers and UI/UX Designers to translate requirements into technical solutions that balance feasibility, user experience, and business value.
  • Optimise applications for performance and scalability, identifying and implementing improvements.
  • Integrate AI technologies into products (e.g. AI-powered features, automation) and adopt AI-assisted tools to improve productivity and quality.
  • Conduct testing, debugging, and code reviews to uphold standards and best practices.
  • Actively participate in Agile ceremonies, supporting effective planning, delivery, and process improvement.
  • Collaborate across squads to drive consistency, reusability, and shared approaches within the wider IP Development team.
Qualifications:
  • Strong full stack development expertise, with experience in both modern front-end frameworks (e.g. React, Angular, Vue.js) and back-end languages (e.g. Node.js, Python, Java).
  • Hands-on experience with databases (SQL and NoSQL), cloud platforms (Azure/AWS), containerisation (Docker), and CI/CD pipelines.
  • Experience applying AI in a business setting—such as integrating AI APIs/services, building AI-powered features, or using AI-assisted development tools (e.g. GitHub Copilot).
  • Good understanding of UI/UX feasibility, responsive design, and delivering user-friendly applications.
  • Strong grasp of testing, debugging, and optimisation practices across the stack.
  • Demonstrated ability to mentor developers and collaborate on wider technical strategy with Principal and Lead Developers, and Engineering Managers.
  • Experience working in Agile teams, contributing to sprint planning, backlog refinement, and collaborative delivery.
  • Strong problem-solving, communication, and collaboration skills, with the ability to align technical work with business goals.
