Lead Frontend Engineer in Leeds

The Role We’re looking for a Frontend Lead Engineer to own and evolve our web and app experiences. This is a senior, hands-on engineering leadership role. You’ll take ownership of our frontend codebases, principles, and delivery — while working insanely closely with product and design to ship high-quality, customer-critical features.
Our primary app codebases are React Native , with React and Next.js used across the wider organisation. You’ll be a key technical leader in the business, setting the bar for quality, collaboration, and reliability in a product that handles real money and real lives.
What You’ll Be Doing Technical Ownership
Own the frontend architecture across our mobile apps and web surfaces
Set and evolve standards for code quality, structure, testing, and performance
Make pragmatic decisions around trade-offs, technical debt, and long-term maintainability
Own frontend release processes, including mobile app store releases and hotfixes
Work extremely closely with our CPO and Lead Product Designer to shape product direction
Translate product ideas into well-scoped, deliverable technical plans
Act as a strong voice for feasibility, quality, and customer impact during product discovery
Quality & Reliability
Champion a strong testing culture (unit, integration, E2E)
Ensure frontend reliability, performance, and crash-free experiences
Take responsibility for bugs, incidents, and regressions — and build systems to prevent them
Team Leadership & Coaching
Coach and mentor frontend engineers, helping them grow technically and professionally
Lead by example through high-quality, hands-on contribution
Foster a collaborative, high-trust engineering culture
Improve team processes, delivery cadence, and developer experience
Identify opportunities to improve tooling, workflows, and shared frontend foundations
Introduce better observability, monitoring, and debugging practices on the frontend
Keep up with the React / React Native ecosystem and bring back what’s genuinely useful
