Senior Site Reliability Engineer

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
