Full Stack Engineer - React/ Typescript - Python

Full Stack Engineer – Crypto / Algorithmic Trading

Crypto / Digital Assets / Algorithmic Trading

We are working with a leading crypto-native algorithmic trading firm looking to hire an experienced Full Stack Engineer to join its London team.

This is a frontend-leaning full stack role, where you'll build sophisticated, high-performance applications used by traders, clients and internal teams.

The majority of your focus will be across React and TypeScript, building complex interfaces around real-time trading and market data. However, you'll also work across the stack and will need previous backend exposure to Python and/or Go.

What You'll Be Working On

You'll help build and develop trading applications, client-facing platforms and internal tools, with the opportunity to create new products from the ground up.

You'll be responsible for:

• Building sophisticated applications using React and TypeScript
• Developing intuitive interfaces for traders and clients
• Building dashboards and applications displaying real-time trading and market data
• Integrating with REST and WebSocket APIs
• Designing reusable frontend components and scalable application architecture
• Working across the backend where required using Python and/or Go
• Contributing to backend services, APIs and data models
• Improving application performance, reliability and security
• Working closely with traders, product teams and other engineers
• Taking ownership of features from initial idea through to production

What We're Looking For

• 5+ years' software engineering experience
• Strong commercial experience with React
• Experience building complex, data-intensive web applications
• Previous backend development experience with Python and/or Go
• Experience working with REST and WebSocket APIs
• Experience handling real-time or streaming data
• Good understanding of relational databases and data modelling
• Understanding of frontend performance and secure application development
• Exposure to cloud infrastructure, ideally AWS
• Familiarity with containers, CI/CD, monitoring and logging

We're looking for someone who is strongest on the frontend, but is comfortable moving across the stack when required. This isn't a pure frontend position — you'll need to understand and contribute to the backend systems powering the applications you build.

Experience within crypto, fintech, trading or financial markets would be advantageous, but isn't essential. An interest in algorithmic trading and digital assets is highly valued.

Why Consider It?

You'll be joining a highly technical and entrepreneurial trading environment where engineers work closely with the traders and teams using the technology they build.

You'll have the opportunity to build products from scratch, solve challenging real-time engineering problems and take significant ownership over both technical and product decisions.

The team operates a hybrid model from its central London office, with flexibility around working from home (3 days in office) and working hours.

Benefits

Free food/ drink in the office, work vacations, conferences, academic allowances, pension, health care
