3 ROLE OVERVIEW

3.1 Job purpose

As a DevOps Site Reliability Engineer (SRE), you will be responsible for ensuring the reliability, scalability, and performance of our systems. You will bridge the gap between development and operations by applying software engineering principles to infrastructure and operations problems. Your role will focus on automation, incident response, monitoring, capacity planning, and improving system resilience while supporting production workloads on Google Cloud Platform (GCP).

3.2 Context

You join OAT's Software Engineering department, reporting to the Staff Engineer, and support the production workloads behind OAT's assessment platform, TAO. You work closely with development, security and operations teams.

3.3 Key responsibilities

Reliability, Scalability & Performance

• Design, implement, and maintain highly available, scalable, and resilient cloud-based infrastructure using Google Cloud Platform (GCP).
• Define and maintain Service Level Objectives (SLOs), Service Level Indicators (SLIs), and Service Level Agreements (SLAs).
• Conduct capacity planning, performance tuning, and load testing to optimize system performance.
• Develop chaos engineering practices to identify and mitigate failure scenarios.

Automation & Infrastructure as Code

• Develop and maintain Infrastructure as Code (IaC) using Terraform, Ansible, or equivalent tools.
• Automate system provisioning, configuration management, and deployments using CI/CD pipelines (ArgoCD, GitOps, GitHub Actions).
• Improve auto-healing and self-recovery capabilities in production environments.

Monitoring & Incident Response

• Monitor system health and performance using Google Cloud Operations Suite (Stackdriver), Prometheus, Dynatrace, Grafana and Datadog.
• Participate in on-call rotation, troubleshoot and resolve production incidents by applying root cause analysis (RCA).
• Implement postmortem processes and drive corrective actions to prevent recurrence.

Security & Compliance

• Implement and enforce security best practices, ensuring compliance with ISO 27001, SOC 2, and GDPR.
• Apply IAM (Identity & Access Management) best practices for secure cloud operations.
• Manage network security, including firewalls, VPNs, and service mesh (e.g., Istio).

Collaboration & SRE Culture

• Work closely with development, security, and operations teams to improve deployment strategies.
• Advocate for blameless postmortems, knowledge sharing, and documentation improvements.
• Lead SRE best practices adoption, including error budgeting and toil reduction.

3.4 Development value

This role offers ownership of the reliability and performance of OAT's production platform, with significant influence over how infrastructure, automation and incident management practices evolve. It provides hands-on exposure to modern cloud-native technologies and SRE practices at scale, supporting future career development towards lead SRE, platform engineering or cloud architecture roles.
