We are evolving our Site Reliability Engineering capabilities to strengthen reliability, observability, security, and operational excellence across our Markets and Risk Intelligence division.

As a Senior SRE
, you will be a senior hands‑on technical person helping shape the foundations of reliability across both new and existing platforms. You will collaborate with Architecture, Engineering, Security, and Platform teams to ensure reliability is built into systems from day one. While this is not a people‑management or shift‑based role, you will work closely with global teams and may occasionally be called upon for major incidents or critical issues.

This position requires a highly proactive, hard‑working expert with strong leadership presence and ownership of platform reliability outcomes.

Key Responsibilities
  • Lead the establishment of SRE foundations for new projects building environments, monitoring, alerting, and ensuring operational readiness from day one.
  • Define, implement, and champion observability standards, tooling, and guidelines across metrics, logs, traces, and SLIs/SLOs.
  • Design and evolve monitoring and alerting solutions that improve visibility, reduce toil, and strengthen system health.
  • Continuously drive reliability improvements across our environments through incident reduction, performance tuning, and building resilient patterns.
  • Partner with Security teams to ensure our platforms meet compliance, security, and risk‑management expectations.
  • Lead seamless handovers from project delivery into BAU SRE operations by ensuring documentation, readiness, and strong operational practices.
  • Be a technical leader and mentor supporting engineers, shaping engineering standards, and fostering a culture of learning and development.
Required Skills and Experience
  • 5+ years of hands‑on technical experience in SRE, Platform Engineering, Infrastructure, or related roles.
  • Strong experience with Azure, including services such as AKS, Azure Container Apps, Virtual Machines, virtual networking (VNet), Azure Active Directory (Entra ), and Azure managed services.
  • Hands‑on experience with Kubernetes and containerized platforms.
  • Proven experience designing and operating observability platforms, including monitoring, logging, and alerting.
  • Hands‑on experience with Datadog for metrics, logs, APM, and alerting.
  • Strong understanding of SRE principles, including SLOs, error budgets, incident management, and reliability engineering.
  • Understanding of cloud security principles and experience collaborating with security teams.
  • Experience with cloud cost optimization strategies and tooling.
Good to Have Skills
  • Experience or working knowledge of AWS.
  • Experience supporting multi‑cloud or hybrid environments.
  • Exposure to Infrastructure as Code (e.g., Terraform, Cloud Formation).
  • Experience in large‑scale, complex, or regulated environments.
  • Knowledge of vector databases and RAG architectures for building internal SRE knowledge assistants.
  • Knowledge of Generative AI and LLM platforms (e.g., Claude, Amazon Bedrock).
  • Experience integrating AI with observability stacks (Prometheus, Grafana, ELK, Open Telemetry) for proactive issue detection.
Person Specification
  • Strong technical authority with the ability to influence design and operational decisions.
  • Highly collaborative, comfortable working across architecture, engineering, security, and operations teams.
  • Calm and methodical under pressure, especially during incidents and critical issues.
  • Pragmatic problem‑solver who balances reliability, security, cost, and delivery speed.
  • Clear communicator, able to explain complex technical concepts to diverse audiences.
