What they need
About the role
We're looking for a Staff Frontend Engineer to join a large-scale digital product environment and take ownership of complex frontend and architecture challenges. This is a hands-on technical leadership role for someone who wants broad influence without moving away from engineering. You'll work across high-traffic customer-facing products, helping shape technical direction, improve performance and scalability, and guide other engineers through complex design decisions.
Key responsibilities
- Designing and evolving frontend architecture across large-scale web applications
- Remaining hands-on with React, TypeScript and modern JavaScript
- Leading system design and technical decision-making
- Improving performance, reliability, scalability and maintainability
- Reviewing code and helping lift engineering standards
- Working across frontend, backend and platform teams
- Mentoring engineers and supporting complex technical problem solving
- Partnering with product, design and architecture on solution direction
- Identifying technical risks, bottlenecks and opportunities for improvement
- Helping teams make pragmatic decisions around architecture and delivery
About you
- Strong experience with React, TypeScript and modern frontend engineering
- Experience operating at Staff, Principal, Lead or senior technical leadership level
- Strong frontend architecture and system design capability
- Experience working across high-traffic or complex customer-facing platforms
- Strong understanding of frontend performance and scalability
- Experience working with APIs, distributed systems and backend services
- Strong knowledge of testing, CI/CD, observability and production support
- Ability to clearly explain technical trade-offs and alternative approaches
- Experience mentoring engineers and influencing technical direction
- Strong communication skills across engineering and product teams
Why join
This role gives you the opportunity to stay deeply technical while having influence well beyond your own code.
You’ll work on meaningful engineering problems at scale, help shape architecture across major digital products and play a key role in raising the technical bar across the team.
If you’re an experienced Lead, Staff or Principal Engineer looking for a role where you can combine hands-on engineering with broader technical ownership, we’d be interested in speaking with you.
