About the role

  • Own the Private Cloud “EC.3” Capacity Management Platform – act as the single accountable owner for capacity planning, forecasting, modelling, and optimisation across the VMware-based Enterprise Cloud v3 environment.
  • Define and Deliver the Capacity Roadmap – translate business demand and programme milestones into a prioritised backlog of features and automation, using Agile delivery practices.
  • Implement SRE Guardrails – establish SLIs, SLOs, and error budgets for infrastructure-related reliability; ensure proactive risk management.
  • Develop Forecasting Models – build accurate short-, medium-, and long-term capacity forecasts using telemetry and scenario analysis to prevent saturation and ensure headroom.
  • Automate Capacity Workflows – reduce manual toil by creating scripts, policies, and integrations for rightsizing, placement, and quota enforcement using PowerCLI, APIs, and IaC.
  • Maintain Real-Time Telemetry & Dashboards – provide a single source of truth for utilisation, trends, and optimisation opportunities through VMware Aria Operations (vROps) and reporting tools.
  • Optimise Cost and Efficiency – align with FinOps principles to deliver show back/chargeback reporting, identify waste, and implement cost-saving measures without compromising reliability.
  • Integrate with ITSM & Governance – ensure ServiceNow CMDB accuracy, automate request fulfilment, and maintain compliance with capacity policies and audit requirements.
  • Collaborate Across Teams – work closely with Architecture, Programme Delivery, Finance, and Operations to align capacity decisions with strategic objectives and risk appetite.
  • Continuously Improve – evolve the capacity management capability through iterative enhancements, stakeholder feedback, and adoption of emerging best practices.

Requirements

  • Capacity Planning & Forecasting – ability to model demand, headroom, and growth scenarios using telemetry and data-driven methods.
  • Automation & Scripting – proficiency in PowerCLI, Python, and API integrations to automate rightsizing, placement, and quota enforcement.
  • Agile Delivery Skills – experience managing backlogs, writing user stories, and delivering incremental improvements through sprints and ceremonies.
  • SRE Practices – strong understanding of SLIs, SLOs, error budgets, and reliability engineering principles applied to infrastructure capacity.
  • Observability & Analytics – ability to design dashboards and alerts for utilisation, saturation, and optimisation opportunities.
  • FinOps Awareness – knowledge of cost optimisation, show back/chargeback models, and unit economics for infrastructure services.
  • Governance & Compliance – familiarity with ITSM tools (e.g., ServiceNow), CMDB data integrity, and audit-ready processes.
  • Stakeholder Engagement – excellent communication and influencing skills to align capacity decisions with business priorities.
