Job description

About Fero:

We’re revolutionising the supply chain and financial foundations of the $800bn global drinks industry by building a platform that will change the way that commerce is executed forever! We’ve just secured our Series A funding and are proud to be part of Notion Capital’s portfolio. We’ve already influenced immense change in the UK markets and have personally already seen tremendous growth, with over £250 million of product transacted through the platform and increased annual sales by 1,000% since early 2023. To date we’re proud to say that we’ve deployed over £500m of funding in support of UK wine and spirits producers. As we look to expand our offering globally we’re looking for ambitious builders that want to change an industry and be part of the journey with us. We’re first to market and intend to stay ahead of the game! In short, it’s the perfect time to join as we aim for unicorn and beyond 🚀

The Role:

We’re looking for a Sr Frontend Developer with full-stack experience (frontend-first) to help build and scale core product experiences from the ground up. You’ll take ownership of key parts of the UI, collaborate closely with product and backend engineering, and help shape the foundations of our web platform.

This is an on-site role in a fast-paced startup environment—ideal for someone who enjoys high autonomy, pragmatic decision-making, and delivering customer value quickly.

What You’ll Do

• Build and ship new product features end-to-end, with a heavy focus on frontend.

• Develop high-quality React + TypeScript user interfaces that are performant, maintainable, and accessible.

• Own 0→1 product build: help set patterns, choose libraries, and establish best practices.

• Collaborate with backend engineers on APIs, data contracts, and integration patterns.

• Translate product requirements into scalable UI architecture and clean component design.

• Improve reliability and quality through testing, monitoring, and thoughtful UX details.

• Contribute to security-minded engineering practices appropriate for a finance domain product.

What We’re Looking For:

• Strong experience building frontend applications with React.js and TypeScript.

• Full-stack experience (you’ve shipped features that touch backend/services), but frontend is your strength.

• Comfort building products in ambiguous environments and making pragmatic tradeoffs.

• Track record of shipping production software in a startup or high-ownership environment.

• Solid understanding of modern frontend patterns:

  • component architecture, state management, forms, data-fetching

  • performance, accessibility, responsive design

• Strong product sense: you care about UX and can partner well with product and operations teams.

Nice to Have:

• Experience in finance/fintech, regulated industries, or building systems that handle sensitive data.

• Familiarity with common backend patterns (REST/GraphQL), relational data models, and authentication flows.

• Experience setting up or improving:

  • design systems / component libraries

  • testing (unit/integration/e2e)

  • CI/CD pipelines

  • observability (logging, metrics, error tracking)

• Exposure to cloud infrastructure and security best practices.
