Fullstack Engineer (Frontend focus)
CoreWeave — London, England, United Kingdom · In-Person · Senior
Role description
Role Overview
The Fullstack Engineer (Frontend Focus) will own and evolve the Monolith platform's product surface, partnering closely with Design, Product, and Backend Engineering to ship UI and UX that feel fast, intuitive, and trustworthy for non-ML expert engineers.
What You Will Do
You'll own significant areas of the Monolith frontend, from architecture and component design to implementation, refactors, and ongoing maintenance. You'll design and build modern, responsive UIs using React and TypeScript, with a focus on complex, data-heavy views.
Why It Might Be a Fit
We're looking for a product-minded craftsperson who cares about the user experience and clarity of a workflow as much as the quality of the code behind it. You'll be a key partner in defining how engineers experience Monolith's 'AI test lab' and will help set the bar for frontend quality, reliability, and developer experience across the team.
