Lightspeed is Citi's flagship CI/CD platform used by 10,000+ engineers across Citi, combining Citi-built technology with leading open-source technologies. The UI chapter is building a modern, scalable frontend experience at the heart of the platform. With a clean, well-maintained codebase running on Angular v21, this is an opportunity to influence the technical direction of a platform operating at significant scale. We’re an engineering-led team that values ownership, collaboration and fresh thinking — including finding smart ways to use AI to improve how we build software.
We’re looking for a UI Technical Lead – Frontend Engineering to own the architectural direction and engineering quality of the Lightspeed UI chapter.
This is a hands-on technical leadership role with a deliberate balance between engineering and leadership. You’ll spend a significant part of your time writing production code, alongside leading code reviews, mentoring the team and providing technical direction. You’ll also play an active role in the day-to-day running of the team and wider technical responsibilities.
You’ll have the autonomy to identify technical opportunities, tackle debt before it becomes a problem and shape the platform for the future. You’ll work closely with Product, Design, Backend and Platform Engineering, acting as the technical voice for the UI and driving high-quality engineering outcomes from idea through to delivery.
- Own and evolve the frontend architecture, standards and engineering practices across Lightspeed.
- Build production software across complex features, architectural improvements and performance initiatives.
- Proactively identify and address technical debt, architectural risks and opportunities for improvement.
- Lead technical design and code reviews, raising engineering standards while mentoring the team.
- Own the component library and design system integration for the Lightspeed UI.
- Champion effective use of AI-assisted development, ensuring generated code is understood, tested, secure and maintainable.
- Partner with Backend and Platform Engineering on integration patterns and CI/CD technologies including Tekton, Jenkins, Harness and TeamCity.
- Own technical Jira work, proactively creating and driving bugs, technical changes and architectural improvements through to completion.
- Work closely with Product and Design to ensure technical priorities, dependencies and risks remain visible.
- Mentor UI Developers and contribute to the team’s technical and career development.
- Strong track record in frontend engineering and technical leadership, with the ability to influence architecture and engineering direction.
- Deep hands-on expertise in modern Angular; the Lightspeed application currently runs on Angular v21.
- Expert TypeScript skills, including advanced types, generics and compiler configuration.
- Strong software engineering fundamentals, including SOLID, design patterns and clean architecture.
- Production experience with React and modern frontend development practices.
- Strong understanding of frontend architecture, including micro-frontends, Module Federation, Nx and scalable state management.
- Expert Git knowledge and experience working with CI/CD, monorepos and collaborative code review.
- Proven ability to proactively identify and resolve technical debt and architectural challenges.
- Experience contributing to or owning a shared component library or design system.
- Practical experience using AI-assisted engineering tools, with a strong focus on validating and testing output.
- Comfortable working in Jira and Kanban environments, taking ownership of technical work without waiting to be directed.
- Excellent communication skills, with the ability to collaborate effectively across Engineering, Product and Design.
- An open, curious mindset and willingness to challenge existing approaches and explore better ways of working.
We’re interested in people who bring more than technical expertise — people who challenge the status quo, think beyond the immediate problem and genuinely care about how software is built. You might have experience working in large-scale enterprise environments, contributing to open-source projects, shaping engineering standards or experimenting with emerging technologies. What matters most is your curiosity, technical judgement and appetite to make things better.
