Data Engineering Lead

We're looking for an experienced Senior Frontend Engineer to join our engineering team and take ownership of our existing frontend application.

ABOUT THE ROLE

As a Senior Frontend Engineer, you'll be responsible for auditing, maintaining, improving, and extending our existing frontend codebase.

A significant portion of the platform has already been developed, so we're looking for someone who can confidently work with an established codebase, identify technical issues, improve existing implementations, and develop new features.

You'll collaborate closely with backend engineers, product designers, QA engineers, and the product manager to ensure we deliver a reliable, scalable, and high-quality product.

- Collaborate with backend engineers to troubleshoot integration issues.

*4. Design & Product Collaboration*
- Translate Figma designs into pixel-accurate, production-ready interfaces.
- Work closely with product designers to maintain UI consistency.
- Build and maintain reusable components using Radix UI and Tailwind CSS.
- Participate in design reviews and provide technical feedback.
- Ensure implementations align with approved designs and product requirements.

*5. Engineering Quality & Delivery*
- Write clean, maintainable, and testable code.
- Implement appropriate unit, integration, and end-to-end tests.
- Review code and maintain engineering best practices.
- Collaborate with QA to identify and resolve issues.
- Participate in sprint planning, engineering discussions, and team meetings.
- Provide regular progress updates and communicate blockers.
- Support deployments and troubleshoot production issues.

1. Audit the existing frontend codebase and document key findings.
2. Identify and prioritise bugs, technical debt, and architectural improvements.
3. Refactor and optimise existing implementations where necessary.
4. Resolve outstanding frontend issues and improve application stability.
5. Take ownership of ongoing frontend development and feature delivery.
6. Maintain code quality, documentation, and engineering standards.

*WHO WE'RE LOOKING FOR*

We're looking for an engineer who takes ownership, thinks critically, and understands how to improve existing systems without unnecessarily rebuilding what already works.

You should be comfortable navigating unfamiliar codebases, making sound technical decisions, collaborating with cross-functional teams, and delivering reliable solutions.
