My client is a rapidly scaling fintech start-up looking for a Junior Front End Engineer (1–4 years’ experience) to join their growing team of talented software engineers.

This is a fantastic opportunity to work alongside experienced technologists from top tech companies and trading firms, contributing to modern, high-performance software used across the FX and Crypto trading space. You’ll be involved in building and improving scalable, reliable front-office trading platforms, gaining exposure to real-world systems used in fast-moving financial markets.

The team values curiosity, strong fundamentals, and a willingness to learn. You’ll be supported by senior engineers and given the chance to develop your skills while working on technology that receives significant real-world exposure.

The team is primarily based in London and works on a hybrid basis, though fully remote options are available for the right candidate.

Requirements:

• 1–4 years’ experience working with JavaScript
• Experience with modern JavaScript frameworks such as React or React Native
• Solid understanding of front-end fundamentals (component design, state management, performance)
• Some exposure to a back-end language (e.g. C#, Java, Python, or C++) is beneficial but not required to be an expert
• Strong communication skills and a collaborative mindset

If you’re a front-end engineer looking to grow your skills in a high-impact fintech environment, this could be a great next step.

If this sounds like you, please don’t hesitate to apply for more details!
