Application Security Engineer II

We’re looking for an Application Security Engineer to join our Information Security team, working closely with Engineering, Infrastructure and Architecture to help us build and maintain secure applications at scale.

This is a hands-on role focused on improving the security of our software development lifecycle. You’ll work collaboratively with engineering teams across multiple products, helping to identify and reduce risk while enabling teams to deliver at pace.
As a member of a globally distributed team, you’ll be comfortable working independently, taking ownership of your work, and proactively engaging with colleagues across regions.

Why join Mintel? 

Mintel is the world’s leading market intelligence agency. Technology underpins our success, enabling us to deliver trusted data, insights, and analysis to clients across the globe. Security plays a critical role in protecting our people, platforms, and data and we’re continuing to invest in building a mature, modern security capability. 

We deliver a culture that values collaboration, learning, and continuous improvement. 

What you will do 

• Own the security triage workflow end‑to‑end (intake → prioritisation → coordination → closure), ensuring issues are handled consistently and driven to completion 

• Investigate and respond to security alerts and incidents across endpoint, identity, and email security 

• Operate and improve security controls within the Microsoft security ecosystem, including Defender, Intune, identity, and Conditional Access 

• Actively contribute to security configuration hygiene and tuning, reducing noise and improving baseline posture over time 

• Coordinate remediation activities with wider IT teams 

• Support incident response activities within agreed guardrails and escalation thresholds 

• Contribute to security improvement projects, including configuration uplift and operational maturity initiatives 

• Identify recurring issues and patterns, feeding them into continuous improvement cycles with the Operational Security Lead 

 

What are we looking for? 

This role is intended for a mid‑level security operations professional. It is not an entry‑level or SOC‑only position. 

To operate effectively, this role is expected to have delegated operational access (within guardrails) to: 

• Microsoft Defender (XDR components relevant to endpoint, identity, email, and cloud app security) 

• Microsoft Intune (device compliance, configuration profiles, investigation support) 

• BYOD security controls 

• Identity & access management, including account investigation, remediation, security group membership management, and participation in scoped Conditional Access changes 

You’ll operate independently within defined guardrails, escalating to the Operational Security Lead when thresholds are crossed, including: 

• Suspected data exfiltration, privileged account compromise, or uncontained malware/ransomware 

• Changes to Conditional Access or global security policies 

• Incidents requiring executive awareness or involvement of Legal / Privacy / DPO 

• Actions that risk widespread disruption or service downtime (e.g. tenant‑wide blocking, mass device isolation) 

Collaboration is the normal operating mode for complex investigations, significant configuration changes, and improvement initiatives. 

Essential knowledge and experience we are seeking 

• Ideally 5 + years of practical experience in security operations, including triage, investigation, and response 

• Experience managing security issues from intake through to closure, coordinating across teams 

• Hands‑on experience with parts of the Microsoft 365 security stack, such as Microsoft Defender 

• Working knowledge of identity and access management, including accounts and group memberships 

• Exposure to endpoint and device security investigations 

• Experience with Microsoft Intune configuration and policy management 

• Experience supporting or contributing to Conditional Access policy hygiene or tuning 

• Confidence making day‑to‑day operational and configuration decisions within defined guardrails 

• Clear written and verbal communication skills 

Desirable knowledge 

• Querying or investigation languages (e.g. KQL) 

• Scripting or automation exposure (PowerShell, Python, Logic Apps) 

• Cloud security exposure (e.g. AWS investigations or hygiene) 

• Experience supporting audits or assurance activities from an operational perspective 

Emergent  

• Interest in how AI and automation are being applied in modern security operations 

• Curiosity about AI‑assisted investigation and response workflows 

• Willingness to learn and adapt as AI‑enabled security capabilities become embedded in day‑to‑day SecOps 

What you’ll get in return 

• A collaborative culture that supports hybrid working 

• Strong emphasis on learning, development, and sharing knowledge 

• The opportunity to build deep, hands‑on experience across modern Microsoft security tooling 

• Real operational ownership and the ability to influence how security works in practice 

• A clear growth path into senior security operations, security engineering, or operational security leadership roles 

Mintel operates globally, with teams based across Europe, the Americas, and Asia‑Pacific.
