Salary: Up to £150k+ Bonus + Full Package

Location: London (Hybrid)

One of London’s most elite fintech firms is hiring a Site Reliability Engineer to join a seriously strong, flat-structured infrastructure team.

This is the kind of environment where engineers report to engineers, good ideas get implemented quickly, and budget is never the blocker. This is often called a "room full of the smartest people in other rooms"

If you’d typically call yourself a Production Engineer, Platform Engineer, Infrastructure Engineer, Linux Engineer, DevOps Engineer or SRE, there is a home for you in this team!

Why join?

• Flexible hours + hybrid working (brand new skyline office in London on a hybrid basis)
• Work in one of the most technically advanced teams in the country
• Heavy investment in cutting-edge and next-gen tech
• Flat structure, low ego, high talent
• Startup-style ownership backed by major resources
• Real autonomy to build, improve and automate

The Role

You’ll sit within an elite Linux-focused infrastructure team responsible for designing and running large-scale, high-availability systems.

This is hands-on engineering. You’ll be:

• Building and evolving resilient, multi-petabyte infrastructure
• Writing Python to automate anything manual or repetitive
• Improving CI/CD pipelines and deployment workflows
• Working closely with engineers across the business to improve reliability and performance
• Enhancing observability, monitoring and system transparency
• Driving automation across config management and container environments

What they’re looking for (or a willingness to learn the below)

• 2–15 years’ experience working deeply with Linux
• Strong Python skills (automation/scripting)
• Experience with CI/CD tooling
• Exposure to Docker and container ecosystems
• Experience with Ansible, Chef, Puppet or similar
• Experience working with large-scale bare-metal environments
• Solid networking fundamentals (TCP/IP, etc.)
• Familiarity with monitoring/observability tooling
• Experience with Kubernetes
• Exposure to distributed storage systems
• Database experience (MySQL/Postgres)
• Messaging systems experience
• Strong ownership mindset and ability to operate in fast-paced environments

This is a chance to join a genuinely elite engineering team in London, working on serious-scale infrastructure with the freedom and backing to do things properly.
