  • Develop and review production‑grade code to support automation initiatives
  • Support incident management and on‑call processes, ensuring production stability
  • Contribute to post‑incident reviews, embedding SRE principles to reduce risk
Requirements
  • Demonstrable experience in SRE or infrastructure operations within cloud environments (AWS / GCP)
  • Strong scripting skills (Python, Ansible, or Power Shell)
  • Experience with Infrastructure as Code and Git Ops methodologies
  • Hands‑on knowledge of observability / APM tools (e.g. Grafana, Datadog, Dynatrace)
  • Proven experience managing incidents, root cause analysis, and on‑call support
  • Understanding of SLA/SLO/SLI frameworks and reliability engineering principles
Desirable
  • Background in software development
  • Experience working within regulated financial services environments
  • Familiarity with ITIL and enterprise service management frameworks
  • Relevant certifications (e.g. AWS, Terraform)
Why Apply
  • Opportunity to shape cloud reliability strategy in a large‑scale environment
  • Work with modern tooling across automation, Dev Ops, and SRE practices
  • Strong emphasis on engineering excellence and continuous improvement
  • Competitive compensation and long‑term career progression
