Job Specification: Site Reliability Engineer (Mid-Level)

Role Overview

We are seeking a Site Reliability Engineer (Mid-level) with strong expertise in AWS cloud infrastructure, containerized platforms, and Azure DevOps CI/CD pipelines. The successful candidate will focus on improving system reliability, availability, performance, and scalability while enabling engineering teams to deliver high-quality services efficiently.

This role blends software engineering with operational excellence, emphasizing automation, observability, incident response, and continuous improvement across cloud-native environments.

Note: This is a reliability-focused engineering role with on-call responsibilities and involvement in platform modernization initiatives.

Qualifications

Key Responsibilities

• Design, build, and operate highly available AWS infrastructure using Infrastructure as Code (Terraform / CloudFormation).
• Develop and maintain CI/CD pipelines to support automated deployments and testing.
• Implement and manage EC2 / containerised workloads using Docker and Kubernetes (EKS/ECS).
• Improve system reliability through automation, monitoring, alerting, and self-healing mechanisms.
• Define and track SLIs/SLOs and error budgets for critical services.
• Participate in incident response, lead root cause analysis, and drive post-incident improvements.
• Build observability platforms using CloudWatch, Prometheus, Grafana, ELK, or similar tooling.
• Automate operational tasks to reduce toil and improve deployment consistency.
• Optimise AWS environments for performance, scalability, and cost efficiency.
• Implement security best practices, including IAM, secrets management, and network segmentation.
• Collaborate with development teams to improve application reliability and deployment strategies.
• Maintain runbooks, architectural documentation, and operational playbooks.

Key Characteristics

• Reliability-driven: Focused on uptime, performance, and resilience.
• Automation-first mindset: Actively reduces manual effort and operational toil.
• Ownership mentality: Takes responsibility for services from design through production.
• Strong communicator: Clearly articulates incidents, improvements, and technical concepts.
• Collaborative: Works closely with platform, security, and application teams.
• Continuous learner: Keeps pace with SRE practices and cloud-native technologies.

Core Experience & Technical Skills

• Strong hands-on experience with AWS services including EC2, VPC, IAM, S3, RDS, CloudWatch, ALB/ELB, and Route53.
• Proven experience creating, managing, and optimising CI/CD pipelines using Azure DevOps.
• Solid Linux/Windows system administration and troubleshooting skills across production environments.
• Hands-on experience with Docker for containerization and working knowledge of Kubernetes ECS/EKS, including container networking, scaling, rolling deployments, and service mesh concepts.
• Strong experience implementing Infrastructure as Code using Terraform and/or CloudFormation.
• Scripting proficiency in Bash and Python for automation and operational tooling.
• Experience automating infrastructure provisioning, deployments, and operational workflows.
• Practical experience implementing observability platforms, including monitoring, logging, and alerting solutions.
• Strong understanding of SRE principles, including SLIs, SLOs, error budgets, incident management, postmortems, and capacity planning.
• Familiarity with performance tuning, load testing, and reliability optimisation techniques.
