About the Role
We’re looking for a Senior Site Reliability Engineer to join our Infrastructure Squad - a lean & senior team where ownership is high and expectations are even higher. This is a deeply hands-on role at the core of a high-traffic system, where you’ll be directly responsible for maintaining reliability, performance, and stability in a fast-paced environment.
You’ll be working on real-time production challenges, handling incidents, managing alerts, and being part of a critical on-call rotation. This role requires resilience, strong decision-making under pressure, and a proactive mindset to continuously improve systems operating at scale.
If you thrive in high-load environments, enjoy solving complex production issues, and want to have a direct impact on systems used by millions - this is the place for you.
Key Responsibilities
Own system reliability by actively monitoring platform health, managing alerts, and responding to incidents in real time
Participate in 24/7 on-call rotations, taking full ownership of production stability in a high-traffic (5–7k RPS) environment
Investigate incidents, perform root cause analysis, and implement long-term fixes to prevent recurrence
Build and continuously improve monitoring, alerting, and observability across the Kubernetes (EKS) ecosystem
Deploy, manage, and optimise infrastructure using Terraform, Helm, and GitOps tools (Flux/ArgoCD)
Drive automation and proactively improve system resilience, reducing manual intervention and recurring issues
Maintain and evolve CI/CD pipelines and infrastructure-as-code practices
Collaborate closely with engineering teams to support deployments and minimise user impact in a live environment
Introduce and integrate new tools and technologies to enhance scalability, reliability, and performance
Handle environment-specific requests and ensure smooth day-to-day platform operations under constant load
Requirements
Strong hands-on experience with Kubernetes (deployment, scaling, troubleshooting) in high-load environments
Experience with GitOps tools such as FluxCD or ArgoCD
Proven experience in incident response, root cause analysis, and postmortems in production systems
Solid experience with AWS, Terraform, Docker, and CI/CD pipelines
Experience with monitoring and observability tools such as Datadog, Prometheus, Grafana, and logging stacks like ELK or CloudWatch
Strong understanding of networking concepts and protocols
Proficiency in at least one scripting language (e.g. Python, Go, Node.js)
Experience working with version control systems (Git)
Familiarity with incident management tools like PagerDuty, Opsgenie, or similar
Ability to operate effectively in a fast-paced, high-pressure environment with strong ownership and accountability
Proactive, resilient mindset with a focus on continuous improvement and system stability
