DATA ENGINEERING AND BIG DATA
TALENT SOLUTIONS
Processing Big Data has become crucial to countless businesses. Those who decide to pursue a career within Big Data face complex development challenges, too tough for relational database systems. After all, there is no Data Science without Data Engineers.
Whilst businesses may have vast quantities of data at the ready, it holds no real value unless it can be stored, harnessed and utilised. It’s estimated that most UK companies have at least 100 terabytes of data stored which could be used for various purposes around the business, as well as newly accessible hard-to-process sources such as web data, image data, and social media data.
This is where those who work in Data Engineering become extremely valuable, as they develop Data Platforms that allow this kind of volume to be processed and used by Data Scientists and analysts across the business.

This team builds the backbone of high-performance web delivery-handling billions of requests per day and powering some of the fastest, most reliable online experiences in the world.
If you’re passionate about distributed systems, high-performance networking, and building software that powers millions of developers, this is an opportunity to have a direct impact on how the web runs at scale.
The Role
As part of the CDN Infrastructure group, you’ll build and enhance distributed systems that make the internet faster and more resilient. You’ll design large-scale systems, write production-grade code, and collaborate closely with product and infrastructure teams to deliver high-impact improvements in routing, caching, and network performance.
You’ll work across key initiatives that include:
- Evolving an internal CDN framework into a fully production-grade product that customers can use directly.
- Designing systems that enable incremental customer migration onto the platform.
- Scaling redirect handling from thousands to billions of requests per site.
- Adding HTTP/3 support and exploring post-quantum cryptography for next-generation security.
- Driving performance optimization across the edge network and core infrastructure.
This is a role for engineers who love building systems that operate at global scale, thrive on technical depth, and want to shape the future of web infrastructure.
What We’re Looking For
We’re looking for backend engineers with strong distributed systems experience and the ability to design, implement, and scale complex infrastructure.
You’ll bring:
- Proven experience with distributed systems, CDN, caching, or ingress infrastructure.
- Go experience in production (C/C++ backgrounds highly transferable).
- Deep understanding of the HTTP layer and modern cloud networking.
- Experience running systems at scale in a cloud product or infrastructure environment.
- Bonus: experience in Linux kernel tuning, performance optimization, or relevant open-source contributions.
This role is ideal for engineers who are hands-on, performance-oriented, and eager to work on problems of scale.
Why Join
You’ll join a team that values technical excellence, autonomy, and impact-where your work directly shapes how developers build and deploy at the edge.
We operate globally, handle traffic at massive scale, and give engineers the ownership to build systems that redefine what’s possible in web performance and reliability.
