Principal SRE Engineer
Entain is seeking a Principal Site Reliability Engineer to establish the technical direction for the reliability, performance, and scalability of its hybrid infrastructure. As the most senior technical authority in the SRE function, the role involves defining architecture and engineering standards across cloud and on-premise environments, driving the adoption of modern SRE practices, and ensuring operational excellence.
This is a hands-on, deeply technical role with significant cross-organisational influence and technical mentorship responsibilities. The successful candidate will operate as a force multiplier, raising the technical bar for the entire engineering organisation rather than managing a team directly.
- Architect scalable, secure, and cost-efficient cloud and hybrid solutions, and establish the patterns and reference implementations other teams build on.
- Define the observability strategy across the organisation: monitoring, logging, alerting, SLIs/SLOs and error budgets using Datadog, Elastic, OpenTelemetry, and similar tooling.
- Set standards for high availability, disaster recovery, and backup across hybrid environments, and validate them through resilience and failure testing.
- Partner with development, security, and platform teams to shape deployment pipelines (CI/CD) and GitOps workflows at scale.
- Establish and maintain organisation-wide technical documentation, runbooks, architectural decision records, and operational standards.
- Identify systemic reliability bottlenecks, lead complex root-cause analysis, and drive down operational load through automation and platform improvements.
- Troubleshoot and resolve the most complex, high-impact production issues, and lead major incident response.
- Provide deep 3rd line technical support and participate in the on-call rotation as an escalation point.
- Act as a technical mentor and role model for SREs and engineers across teams, raising the overall engineering bar through coaching and knowledge-sharing.
- Lead structured up skilling and enablement across Windows, Linux, AWS, and Kubernetes.
- Influence and align Product, Engineering, Security, Platform, and Operations teams around reliability goals and technical direction.
- Shape the SRE roadmap together with SRE Leadership and SRE Guild and drive prioritisation of key reliability and platform initiatives.
- Communicate technical strategy and trade-offs clearly to both engineering teams and senior stakeholders, and drive accountability for reliability outcomes.
- Champion a culture of operational excellence, ownership, and continuous improvement across the organisation.
- 10+ years of experience in SRE, DevOps, Platform Engineering, or Cloud Engineering, with a track record of operating at a senior or principal level (required).
- Deep, hands-on expertise with On-prem and large-scale AWS environments (required).
- Expert-level experience running Kubernetes in production (EKS, EKS Anywhere, EKS Hybrid preferred), including cluster design, scaling, and hardening (required).
- Proven background leading migrations of IIS/.NET and Linux-based applications to cloud and Kubernetes (required).
- Expert-level Infrastructure-as-Code skills, particularly Terraform, including module design and standards for large teams (required).
- Deep knowledge of GitOps (ArgoCD), automated deployments, and configuration management (required).
- Exceptional troubleshooting skills across Windows, Linux, networking, and distributed systems (required).
- Strong experience with observability platforms (Datadog, Prometheus, OpenTelemetry) and defining SLI/SLO/error-budget practices (required).
- Strong understanding of security best practices in cloud and hybrid environments (required).
- Experience operating in 24/7 high-availability, mission-critical environments (required).
- Excellent communication and cross-team collaboration skills, with the ability to influence technical decisions without direct authority (required).
- Demonstrated success mentoring senior engineers and driving org-wide technical standards (required).
- Safe home pickup and home drop.
- A regular bonus and great pension.
- 24 days annual leave.
- Extra paid leave, including wellbeing and development days.
- Life assurance and Income Protection.
- Private healthcare and wellbeing support.
- INR 3,000 per month Communication allowance.
- Up to INR 16,000 per year in Crèche expenses (children under 3).
