Job description

Site Reliability Engineer/Production Support Engineer | FinTech |

London | 4 Days Onsite

Are you the engineer people turn to when production goes wrong?

We're partnering with a fast-growing FinTech building mission-critical banking technology for regulated financial institutions. As the platform continues to scale, they're looking for a Site reliability engineer/Production Support Engineer who can take real ownership of production while working across the boundaries of Support, SRE, DevOps and Software Engineering.

This is a hands-on production role at its core. You'll be responsible for investigating incidents, restoring services and identifying root causes, but you'll also have the opportunity to go deeper, whether that's improving observability, working with cloud infrastructure, automating processes or getting into the backend code to implement smaller fixes and improvements.

Being a growing FinTech means responsibilities aren't confined to one box. They're looking for someone who enjoys wearing multiple hats and wants genuine ownership over how production is supported and improved.

What you'll be doing

• Taking ownership of production incidents end-to-end, from initial investigation and incident response through to resolution and post-incident review.
• Troubleshooting complex issues across applications, infrastructure, databases, APIs and distributed systems.
• Performing Root Cause Analysis (RCA) and helping implement permanent fixes and preventative improvements.
• Working within structured production processes including ITIL, change management, CAB and incident/problem management.
• Improving monitoring, alerting and observability to identify issues before they impact customers.
• Working hands-on with AWS or GCP environments and collaborating closely with SRE/DevOps and Platform teams.
• Reading and debugging backend code, making smaller bug fixes, modifications and production improvements where appropriate.
• Automating repetitive operational processes and improving the efficiency of production support.
• Supporting releases and deployments into production.
• Working closely with Software Engineering to resolve larger or more complex application issues.
• Participating in a compensated out-of-hours on-call rota.

What we're looking for

• Strong experience within Production Support, Application Support or Production Engineering.
• Experience operating at L2/L3 level, with the ability to investigate complex technical issues rather than simply escalating them.
• Strong knowledge of incident management, incident response, RCA, change management and production support processes.
• Hands-on experience with AWS or GCP.
• Exposure to SRE/DevOps practices, CI/CD and modern production environments.
• Experience with monitoring and observability tooling such as Grafana, Prometheus, Datadog, Splunk, New Relic or similar.
• Comfortable reading, debugging and modifying backend code. The specific programming language isn't important, Python, Java, Go, C#, Kotlin or similar are all relevant.
• Experience supporting distributed, event-driven or highly available systems.
• Comfortable working closely with Software Engineering, DevOps/SRE and Infrastructure teams.

Nice to have

• FinTech, banking, payments, trading or wider financial services experience.
• Terraform or other Infrastructure as Code tooling.
• Kubernetes and Docker.
• Experience within a startup or scale-up environment.
• Experience supporting high-volume or business-critical transactional platforms.

London – 4 days onsite

If you're a Production Support Engineer who enjoys going beyond the ticket queue, getting into the infrastructure, understanding the code and improving how production operates, I'd be keen to speak.
