About The Role

We are looking for a highly experienced Service Manager to oversee the design, implementation, and management of Software Defined Networking (SDN) services, with a strong focus on micro-segmentation. The role is delivered under an Ad-Hoc contract of the COSMOS framework, supporting the European Commission (DIGIT).

The ideal candidate must have hands-on experience in micro-segmentation—defining, documenting, monitoring, and improving policies and delivery processes—and must ensure this security-centric service is fully aligned with DIGIT’s operational, security, and strategic goals.

Key Responsibilities

Service Management & Operations

• Manage end-to-end delivery of SDN services with micro-segmentation as a core component.
• Design and document micro-segmentation policies, workflows, and service definitions.
• Monitor the enforcement of segmentation policies and ensure services are performing as expected.
• Act as the main point of contact for DIGIT on all SDN service matters, including segmentation.
• Ensure alignment with contractual SLAs and KPIs, particularly those related to segmentation controls and security enforcement.
• Lead the incident, change, and problem management processes related to SDN and segmentation services.
• Drive implementation of monitoring dashboards for micro-segmentation effectiveness.
  
  

Stakeholder & Vendor/Supplier Management

• Work closely with DIGIT units and other EC stakeholders to define business-driven segmentation policies and enforce them accordingly.
• Manage relationships with vendors and ensure that micro-segmentation capabilities are properly supported, maintained, and evolved.
• Lead service review and governance meetings focused on SDN and segmentation compliance and maturity.
• Organize and lead regular service review meetings with DIGIT and Service Provider operational teams.
• Provide clear, data-driven reports on service performance, risks, and improvement plans.
  
  

Service Transition & Continuous Improvement

• Lead the definition of the micro-segmentation service within the SDN catalog (including standard and non-standard offers).
• Support the integration of SDN micro-segmentation with hybrid and multi-cloud services.
• Identify and implement automation for segmentation rule provisioning and policy lifecycle management.
• Promote micro-segmentation adoption across EC services and ensure alignment with Zero Trust and security-by-design principles.
• Drive service evolution and innovation, ensuring SDN services align with the EC’s cloud and digital transformation strategy.
• Identify areas for automation and efficiency in SDN operations.
• Support the adoption of emerging SDN technologies to improve agility, security, and scalability.
• Ensure effective knowledge management and documentation within the service provider team.
