We're looking for a Senior Software Engineer to join our Application Operations team.

This is a hands-on engineering role for people who enjoy solving complex production problems and applying software engineering principles to operational challenges. We're building a team of highly capable engineers who combine technical expertise, curiosity and analytical problem-solving skills to improve reliability, drive automation and eliminate recurring issues. As we continue to reduce repetitive operational work through automation, our engineers are empowered to focus on high-value challenges in reliability, operational excellence and continuous improvement.

You'll play a key role in reducing operational toil, increasing automation and improving service reliability, partnering closely with Software Engineering, Platform and SRE teams across the organisation.

Core technologies: AWS (EKS/Kubernetes), PHP, MySQL, Datadog, Kibana and Heap.

What You'll Do

• Resolve complex application and platform issues within clearly defined engineering guardrails.
• Diagnose production incidents, perform safe remediation and reduce unnecessary escalation to L3 teams.
• Build automation, scripts, runbooks and tooling that improve operational efficiency and reduce MTTR.
• Use Datadog, Kibana and Heap to investigate issues, understand customer impact and improve service health.
• Partner with Software Engineering, SRE and Platform teams to improve observability, reliability and operational readiness.
• Contribute to service onboarding, post-incident reviews and continuous improvement initiatives.

What We're Looking For

• Experience in Application Operations, Production Engineering, SRE or a similar operational engineering environment.
• Experience supporting cloud-hosted applications, ideally PHP services running on Kubernetes (EKS) with MySQL databases.
• Strong troubleshooting and diagnostic skills, with the ability to understand systems end-to-end.
• Hands-on experience with PHP, Python or another backend language.
• Practical Kubernetes knowledge, including deployments, logging, monitoring and safe rollbacks.
• MySQL operational experience, including performance investigation and query analysis.
• Experience with observability platforms such as Datadog and log analysis tools such as Kibana.
• Strong communication skills and a passion for automation, continuous improvement and engineering quality.

Nice to Have

• Python development experience.
• Feature flag platforms and configuration-as-code.
• AWS services such as S3, SQS, ALB and CloudWatch.
• Experience with SLOs, service onboarding and operational readiness.

Working Pattern & On-Call

• Standard hours: Monday to Friday, 9am to 6pm.
• 1-in-4 on-call rotation.
• £500 on-call allowance per week.
• Additional hourly payments for call-outs.
• Enhanced rates for public holiday coverage.
• Historically low call-out volumes, supported by a strong focus on automation, operational maturity and continuous improvement.

Interview Process

• Screening call with a member of the Talent Acquisition Team
• First stage interview with Application Operations Leadership and peer (practical scenario or technical assessment relevant to the L2.5 operating model)
• Final stage interview with Director or VP
