Lead Fullstack Engineer

Full-Stack Engineer

Location: London (Hybrid)

Salary: Up to £80,000 + benefits

We have partnered with a well-funded, founder-led technology startup operating in the sports and media space, building next-generation systems for processing and analysing live content in real time.

As the platform scales, they’re hiring a Full-Stack Engineer to design and deliver high-performance systems across real-time data pipelines, modern frontend applications, and AI-enhanced product features.

What You'll Do as a Full-Stack Engineer:

• Design and build resilient, high-throughput backend services in Java that power the movement of data across millions of sporting events each year.
• Architect and maintain real-time event-driven data pipelines and streaming systems at scale.
• Own cloud-native infrastructure decisions, working across serverless and containerised environments to deploy and operate production-grade distributed systems.
• Take end-to-end ownership of real-time video and data delivery across our digital content platform.
• Build and maintain frontend interfaces in TypeScript/React as needed, internal tooling means this is a lighter, cross-functional responsibility.
• Integrate LLM APIs and AI-powered workflows into product functionality, and leverage AI coding assistants to accelerate development.
• Collaborate closely with a small, high-trust team to ship and iterate quickly.

Core Technology Stack:

• Backend: Java, distributed messaging systems, relational databases, Docker, infrastructure as code
• Frontend: TypeScript, modern JavaScript frameworks
• Infrastructure: Cloud-native serverless and containerised environments
• AI Tooling: Regular use of AI-powered development tools and coding assistants

What We’re Looking For in a Full-Stack Engineer:



• A polyglot engineering mindset with the ability to work across multiple languages and systems.
• Strong experience building backend services and distributed systems.
• Ability to read, understand, and contribute to Java-based systems.
• Frontend experience with modern frameworks such as React, Vue, Svelte, or similar technologies.
• Hands-on experience integrating LLM APIs from leading providers.
• Regular use of AI tools and coding assistants to increase development velocity and automate workflows.
• Strong engineering fundamentals including testing, documentation, security, and performance optimisation.
• Comfort working in fast-moving environments where ownership, clarity, and delivery are expected.

Nice to Have’s as a Full-Stack Engineer:

• Experience in sports technology, live event data systems, or digital media platforms.
• Exposure to streaming technologies or real-time data processing frameworks.
• Strong experience designing data architectures and large-scale distributed systems.

This is a rare opportunity for a Full-Stack Engineer to help shape a real-time digital platform from an early stage, working with modern cloud infrastructure and AI-augmented engineering workflows to deliver high-impact systems.
