6 month contract with extensions

$******** a day including super DOE
n
This isn't just another React contract.
n
We're looking for a Senior Front-End Engineer who can help shape how frontend engineering is done across an entire team.
n
You'll join a growing engineering function building a sophisticated client-facing platform used to plan, book and measure advertising campaigns.
n
It's a genuine product engineering setting - not just building screens. You'll be working closely with backend engineers, Product, Design, Data and QA to turn complex business problems into intuitive, scalable web experiences.
n
What you'll be working on
n
The platform is built around React and TypeScript, with a Kotlin/Spring Boot backend and GCP infrastructure. You'll be responsible for building and evolving frontend experiences across the platform, including:
n
n
Developing new React/TypeScript components
n
Integrating with backend APIs
n
Designing frontend solutions and breaking requirements into technical work
n
Improving frontend performance and scalability
n
Maintaining high standards around testing and code quality
n
Reviewing code and providing constructive feedback
n
Troubleshooting production issues
n
Working closely with backend engineers to deliver features end-to-end
n
Helping establish consistent frontend patterns and practices across squads
n
n
But here's the important bit... They'll be looking for someone who has a point of view on frontend engineering.
n
Someone who can look at the way things are being built and say:
n
"There's a better way we could do this."
n
And then explain why, bring people along with them and help implement it.
n




You'll be expected to:
n
n
Mentor and coach other engineers
n
Help establish frontend best practices
n
Influence patterns across multiple squads
n
Give constructive technical feedback
n
Work collaboratively rather than operate in isolation
n
Stay hands-on with React and TypeScript
n
Think about the end-to-end user experience, not just the UI layer
n
n
You'll probably bring
n
n
~6+ years' professional software engineering experience
n
Strong React experience
n
Strong JavaScript / TypeScript
n
Extensive modern frontend development experience
n
Experience building production web applications
n
Strong understanding of frontend architecture and design patterns
n
Testing experience / TDD or BDD awareness
n
Strong API integration experience
n
Excellent communication and collaboration skills
n
A willingness to mentor and influence other engineers
n
n
Full-stack experience is a big plus, particularly if you're comfortable jumping into backend work when required.
n
Experience with Next.js, GCP,
authentication/authorisation,
web performance or modern AI-assisted development would also be highly relevant.
n
Why this one is interesting
n
You'll be joining at an interesting point in the team's evolution. They're establishing common frontend patterns across squads while simultaneously building out a new platform - so you won't simply be inheriting someone else's way of doing things. You'll have the opportunity to influence the engineering direction while staying genuinely hands-on. And there's plenty of interesting technical territory: complex data, high-volume metrics, campaign management, reporting, integrations and a client-facing product sitting at the centre of a growing retail business. Lots of potential for extensions, too!
