Full Stack Engineer (React/Python)

• *Full Stack Engineer (React / Python - Frontend Leaning)
• *London (hybrid)
• *Up to £70,000 + bonus + benefits
• *29 days holiday + bank holidays (37 total)

What will you be doing?

You'll be working for a fintech start-up that is used globally by Tier 1 investment banks, Large Entripises and trading firms specialising in LLM's and real-time data.

The product sits right at the edge of where things are going.

• *LLMs, real-time data, and fintech**

, all combined into something that’s actually being used in live environments.

There’s a huge amount of greenfield work. You’re not inheriting years of bad decisions or buried in tech debt. You’ll be helping define the architecture, the standards, and how the platform evolves as it scales.

You’ll get real ownership early and work with really strong engineers who care about what they’re building. Engineers are trusted by the company to ship code so there isn't endless red tape.

The role leans frontend, so if you enjoy building fast, clean, high-quality UIs in React, you’ll love it. But you’ll also work with some Python and across the stack now and then.

Tech Stack

• React
• Python
• Cloud (AWS or similar)

Bonus (not a deal breaker):

• Start-up experience
• B2B product exposure
• Experience with AI / LLMs / data platforms
