• Administer and manage Microsoft 365 environment including users, groups, enterprise applications, licensing, SSO, and SCIM provisioning • Maintain identity and access management processes • Provide ongoing operational support across the M365 ecosystem • Ensure security, compliance, and best practices are implemented • Support and optimise AWS-based infrastructure and services • Improve operational efficiency of an AWS-based AI platform • Maintain CI/CD and repository environments • Assist in system performance monitoring, reliability, and automation initiatives • Migrate Bitwarden from self-hosted to SaaS • Lead migration from Mattermost to Microsoft Teams • Transition from Maxotel to Microsoft Teams Phone • Migrate GitLab repositories to Bitbucket • Perform configuration cleanup and optimisation of Nginx and WordPress environments • Work closely with internal stakeholders and technical teams • Provide regular reporting and updates on projects and operational improvements • Maintain clear technical documentation and process records

• Own the reliability, availability, and performance of production systems. • Lead incident response for production issues. • Conduct blameless postmortems and ensure follow-up actions are completed. • Design, provision, and manage AWS infrastructure using Infrastructure as Code (IaC) tools. • Own and continuously improve CI/CD pipelines for secure builds, tests, and deployments. • Perform capacity planning and load analysis to ensure systems scale predictably. • Lead and execute infrastructure and platform migrations.

• Define and own reliability goals for network services and critical paths (SLIs/SLOs, availability targets, error budgets where it makes sense) • Drive reliability improvements across the whole network: not only services, but also site readiness, inter-site connectivity (DCI), and operational standards • Own incident response for your areas, lead investigations/postmortems, and turn failures into durable fixes (not repeated firefighting) • Build and evolve observability: actionable metrics/logs/traces, alerting, and faster debug loops during and after incidents • Design safer change workflows: automation, CI/CD, test/staging environments, canarying, rollbacks, and auditability for network changes • Work closely with network engineers and platform teams to embed operability into designs and keep operations practical and fast

• Lead the definition, advocacy, and adoption of SRE principles across engineering teams • Partner with leadership to shape long-term reliability, resiliency, and observability strategies • Champion distributed tracing, real user monitoring (RUM), and key performance metrics such as Largest Contentful Paint (LCP) to improve system visibility and user experience • Build and scale self-healing systems to minimize manual intervention and reduce downtime • Drive enterprise-wide improvements to incident response processes, including those related to Machine Learning systems • Collaborate closely with Development Productivity and Quality teams to improve engineering velocity without sacrificing reliability • Influence technical and operational roadmaps through data-driven insights and hands-on technical contributions • Own and deliver cross-functional initiatives from concept through execution, applying program management skills to align stakeholders and achieve results
