Full Stack Engineer (React / Python) – FinTech Trading Platform – Up to £70K + Equity – Hybrid, London (Vauxhall)


Really interesting early-stage FinTech role building a platform that turns global news, macroeconomic data, geopolitics and policy signals into real-time market intelligence for financial institutions.


The system processes huge volumes of global information daily, helping traders and investment teams understand what is moving markets in real time.


You’d be joining a small engineering team early and working directly with a technical founder who previously led Merrill Lynch in London and Citi Bank in Singapore.


They’ve recently raised multi-million funding and are now looking to add one more engineer to help scale the platform.


Tech Stack


• Python

• React (Next.js)

• AWS (open to engineers with any cloud experience)


What you’ll be doing


• Building React dashboards used by financial institutions

• Developing Python services that process and structure global data signals

• Working on a real-time data platform analysing global economic events

• Collaborating directly with the founder and core engineering team


What they’re looking for


2+ years commercial software engineering experience

• Experience with React or Python. They’re open to any full-stack background, so it doesn’t matter if you lean more backend or frontend.

• Someone who enjoys working in a fast-moving early-stage product environment


Why this role stands out


• Join early and have real product impact

Equity as part of the package

• Learn directly from an experienced fintech founder

29 days holiday + bank holidays (rare for a start-up, most are 22-25 days holidays)

• Hybrid working in London (Vauxhall)


If you're interested in building real-time systems and working with modern web technologies in FinTech, this is a great opportunity to join early and grow with the platform.



Don't worry if you don't have a CV that is up to date. We can cross that bridge later.
