Senior Cloud Security Consultant

CELON is a UK-based technology consultancy specialising in cloud, security, managed services and digital transformation. We work with enterprise clients to secure and operate complex cloud environments through practical, delivery-focused consulting.

About the role

We are looking for a Senior Cloud Security Consultant to work with clients on the analysis, remediation and reduction of security vulnerabilities across complex cloud environments. This is a hands-on, client-facing consulting role. The successful candidate will be comfortable working with cloud security tooling, scripting and automation, and applying security controls in real-world enterprise environments. The role requires strong technical judgement, the ability to assess risk and impact, and a proactive mindset focused on reducing repeat issues rather than continually reacting to them. While the role is Azure-focused, it requires broader cloud security experience and the ability to work confidently across infrastructure, platform and application-facing services.

Key responsibilities

• Work as a consultant supporting client cloud and security initiatives
• Analyse and interpret security findings from cloud security and vulnerability management tools (e.g. Wiz, Defender for Cloud, or similar)
• Understand the underlying technical issues, risks and potential business impact of identified vulnerabilities
• Assess remediation options, considering security risk, operational and application impact, dependencies on vendors or specialist teams, and enterprise change and release constraints
• Carry out and support remediation activities, including Azure configuration and security hardening, platform and OS patching, and implementation of compensating controls where full remediation is not possible
• Use scripting and automation to support repeatable remediation activities, reduce manual effort, and help prevent recurring vulnerabilities
• Apply and align remediation activities with recognised security frameworks (e.g. CIS, NIST, ISO 27001) in enterprise environments
• Work with stakeholders across and beyond IT, including infrastructure teams, security teams, application owners and external vendors
• Produce clear, professional documentation suitable for client delivery and audit purposes

About you

• 10+ years' experience in a senior cloud, infrastructure or security engineering / consulting role
• Strong hands-on experience with Microsoft Azure, including Virtual Machines and PaaS services, Azure networking (VNets, NSGs, firewalls, private endpoints), and Identity and access management (Microsoft Entra ID, RBAC, managed identities)
• Solid understanding of cloud security vulnerabilities, CVEs and risk-based prioritisation
• Experience working with cloud security posture management and vulnerability tooling
• Strong understanding of server-side security (Windows Server and/or Linux)
• Proven experience with scripting and automation (PowerShell, Bash, Python or similar)
• Practical experience applying security frameworks such as CIS, NIST or ISO 27001 in enterprise environments
• Ability to assess risk and provide pragmatic, defensible recommendations
• Comfortable working in a consulting role with delivery expectations and client accountability
