Senior Infrastructure Engineer (Site Reliability Engineer)

About the role

ToolsGroup, a supplier of service-driven supply chain planning software, is looking for an experienced Site Reliability Engineer who can also lead IT service operations. You will lead a small IT/Ops team, stay the senior technical escalation point for production services and act as the operational interface between IT/Ops, Engineering, Product, Security, Support and business teams. The role is not a coordination-only service management or generalist infrastructure position.

Key responsibilities

• Lead major incidents from impact assessment and containment through recovery, stakeholder communication, root-cause analysis and corrective actions.
• Troubleshoot complex issues across Windows and Linux, Kubernetes and container workloads, hybrid networking and DNS, cloud infrastructure, identity, authentication, databases, storage, APIs and service dependencies.
• Operate and improve Azure, OCI or comparable cloud environments, including monitoring, access controls, backup and recovery, reliability and cost-aware scaling.
• Define and improve service-level indicators, observability, alert quality, capacity, resilience, dependency mapping and recovery readiness for critical services.
• Automate operational tasks and controls using PowerShell, Python, infrastructure as code or CI/CD pipelines, with validation, logging, secure credential handling and rollback.
• Apply incident, change and problem management pragmatically, and connect technical and business teams around service ownership, dependencies and risk trade-offs.

Required profile

• Strong SRE or production engineering background, typically 5+ years operating business-critical, customer-facing or high-availability services.
• Recent direct technical ownership of services, including high-severity incidents with triage, recovery decisions and follow-through.
• Experience leading, mentoring or acting as senior escalation point for other technical professionals, with strong business-facing and cross-functional leadership.

Required skills

• Windows and Linux, TCP/IP, DNS, routing, firewalls, proxies or load balancers.
• Azure, OCI or similar cloud platforms, including compute, storage, networking, IAM, observability, backup and recovery.
• Kubernetes and containers, including scheduling, networking, persistent storage, secrets, scaling and rollback.
• Metrics, logs, distributed tracing, actionable alerting, SLI/SLO design and post-incident engineering.
• Active Directory and Microsoft Entra ID or equivalent, including hybrid identity, MFA, service identities and gMSAs.
• Automation and infrastructure as code with PowerShell, Python, Terraform or comparable tooling and CI/CD.
