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




Mentor and coach other engineers
Help establish frontend best practices
Influence patterns across multiple squads
Give constructive technical feedback
Work collaboratively rather than operate in isolation
Stay hands-on with React and TypeScript
Think about the end-to-end user experience, not just the UI layer
You'll probably bring
~6+ years' professional software engineering experience
Strong React experience
Strong JavaScript / TypeScript
Extensive modern frontend development experience
Experience building production web applications
Strong understanding of frontend architecture and design patterns
Testing experience / TDD or BDD awareness
Strong API integration experience
Excellent communication and collaboration skills
A willingness to mentor and influence other engineers
Full-stack experience is a big plus, particularly if you're comfortable jumping into backend work when required.
Experience with Next.js, GCP, authentication/authorisation, web performance or modern AI-assisted development would also be highly relevant.
Why this one is interesting
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 compelling 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!
