About The Position

Site Reliability Engineer The infrastructure doesn't run itself - and in high-frequency financial markets, "good enough" isn't a concept that exists. This is a role where what you build directly underpins mission-critical trading operations at scale. A recognised leader in fixed income trading connectivity, this fintech delivers a hosted integration platform for some of the world's most demanding financial institutions. The SRE team is a true generalist unit - from endpoint support to data centre provisioning and cloud infrastructure. We're looking for someone who thrives in an automation-first culture, brings a solid foundation in both systems and networking, and is equally comfortable deep in config files or on a call negotiating with a hardware vendor. You don't need to be the loudest voice in the room - you need to be the one who gets things done and keeps learning while you do it.

Requirements

Hands-on coding ability - not senior dev level, but you can write a working program in your language of choice. This is a hard requirement
Background as a sysadmin or network engineer - ideally both, or at minimum a solid working understanding of the other discipline
Practical experience with infrastructure automation tooling (e.g. Ansible) - everything is automated here; this is non-negotiable
Proven track record managing external vendors and third parties - via email, phone, and in negotiations; including hardware purchasing and enabling remote work setups
A growth mindset - self-motivated, open to feedback, and honest about the limits of your knowledge
Based in the UK or Europe, with availability to work UK business hours (9–5)

Nice To Haves

Familiarity with authentication protocols: SAML, OAuth2, Active Directory, Kerberos
Microsoft / Azure Active Directory administration
Database high availability experience - clustering or replication setups, particularly Postgres

Responsibilities

Design and implement automated server and network provisioning across physical infrastructure and cloud environments (AWS, GCP)
Continuously develop and improve the Continuous Delivery pipeline responsible for server, switch, and software deployments
Manage relationships with hardware vendors, telecom providers, and financial institutions - from procurement to ongoing coordination
Share full team ownership of the environment - no "that's not my area" mentality here
Take initiative on improvements without waiting to be told - autonomy is expected, not just tolerated
