About The Team

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.

The Role

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.

Key Responsibilities

• 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.

Key Skills & Experience

• 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.

What Would Set You Apart:

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.
