We combine AtkinsRéalis project management expertise and Hitachi Energy's deep technological knowledge to create a company dedicated to substations – we are Linxon!

The Application Security & IAM Lead is accountable for end‑to‑end application security and identity & access management across Linxon's engineering platforms, enterprise applications, SAP ERP, SaaS tools, and AI‑enabled systems.

The role ensures applications are secure‑by‑design, access‑controlled, compliant, auditable, and operable, while supporting application separation, migration, ERP transformation, and responsible AI usage.

What will you do?

Application Security

  • Own application‑level security across:
    • Engineering & BIM platforms (Autodesk, Bentley, Trimble)
    • Project Controls systems (Primavera P6, MS Project, Procore)
    • Microsoft 365 and Power Platform
    • SAP ERP (S/4HANA, ARIBA)
    • SaaS and AI‑enabled applications
  • Embed secure‑by‑design principles across the application lifecycle
  • Participate in architecture reviews and mitigate application security risks
  • Oversee vulnerability identification, prioritisation, and remediation

Identity & Access Management (IAM)

  • Own IAM for all applications, including:
    • Joiner / mover / leaver processes
    • Role‑based and least‑privilege access
    • Privileged access governance
  • Govern authentication and access controls (SSO, MFA, conditional access)
  • Ensure access ownership, documentation, logging, and auditability

SaaS, Cloud & Engineering Tool Security

  • Assess security posture of SaaS and vendor‑managed platforms
  • Embed security requirements into application onboarding, renewals, and vendor selections
  • Reduce security risk from tool sprawl, unmanaged accounts, and shared access

SAP ERP & Enterprise Application Security

  • Own application security and IAM for SAP ecosystems
  • Govern SAP roles, authorisations, and access models
  • Support ERP transitions (Oracle → SAP, Workday integrations) from a security and access perspective
  • Ensure SAP security aligns with enterprise IAM and audit requirements

AI Systems Security & Regulatory Awareness

  • Support identification and governance of AI‑enabled systems
  • Ensure AI solutions implement strong access controls, logging, and accountability
  • Contribute to EU AI Act readiness through security, access, and audit inputs
  • Work with architecture and data teams to mitigate AI‑related risks

Migration, Separation & BAU Alignment

  • Embed security and IAM into:
    • Application separation from parent IT
    • Migrations, cutovers, and hypercare
  • Prevent security or access gaps during transitions
  • Support L2/L3 teams with clear security and escalation models

Governance, Audit & Risk

  • Define and enforce application security and IAM standards
  • Act as security design authority for application access decisions
  • Support audits with clear evidence of access and control effectiveness
  • Proactively identify and manage application‑level security risks

Experience, Education and other Required:

  • 8–12+ years in application security and IAM roles
  • Strong experience securing enterprise and SaaS applications
  • Practical IAM expertise (RBAC, MFA, SSO, least privilege)
  • Exposure to SAP application security and ERP transitions
  • Awareness of AI‑enabled systems and governance expectations
  • Strong stakeholder communication and risk‑based judgement
  • Reduced application security incidents and access violations
  • Complete, auditable IAM coverage across all applications
  • No critical audit findings related to application security or access
  • Secure migrations with no access regressions
  • Reduced unmanaged access and improved vendor security posture

What we offer:

In return, we offer a wide range of rewards and benefits,

  • 20 days Privilege Leave, 13 days Emergency leave and 14 Public holidays per year
  • Global Career Progression Opportunities
  • Medical Insurance, Life Insurance
