eSIM Consultant - SC Cleared

eSIM Consultant/Architect - SC Cleared

Location: UK (Hybrid - 2 days onsite initially, Full time onsite during deployment)
Active SC Clearance: Essential

We are seeking a specialist eSIM Consultant/Architect to support the greenfield eSIM capability build for a UK telecoms client.

You will join an established delivery team (6-7 consultants already onsite) and play a key role in defining, designing, and shaping the technical direction of a new eSIM platform for a telco/MVNO-style environment.

This is a hands-on advisory role for someone with direct experience architecting and deploying eSIM systems, rather than general mobile or cloud engineering.

Key responsibilities include:

• Designing and shaping a greenfield eSIM architecture
• Advising on GSMA standards and compliance (eg SGP.02/SGP.22)
• Defining subscriber life cycle, provisioning, and profile management
• Supporting decisions around SM-DP+/SM-SR, integrations, and vendor selection
• Acting as a technical authority to set direction during early project phases
• Supporting deployment phases as the platform moves towards implementation

The role is intentionally technology-agnostic, focused on setting direction rather than promoting a specific vendor or solution.

Required Experience

• Proven experience designing and deploying eSIM platforms for a telco or MVNO
• Strong background in telecoms/mobile core engineering
• Hands-on experience with:
  • eSIM provisioning and life cycle management
  • GSMA eSIM specifications and standards
  • Subscriber management and mobile core integrations
• Comfortable operating in early-stage, greenfield environments
• Able to provide clear technical leadership and pragmatic guidance
