Key Responsibilities

1. Solution Architecture & Design

• Design the endtoend encryption solution for sensitive workloads on AWS (technical architecture, operating model, governance framework).
• Integrate AWS KMS, XKS, CloudHSM with Thales HSMs and SGs security ecosystem.
• Ensure solution alignment with SGs cloud, cybersecurity, and compliance standards.
• Define dependency mapping, lifecycle management, and disaster recovery/BCP for keymanagement services.

2. Validation & CrossTeam Alignment

• Present and validate the solution with Architecture teams, Security teams, and Cloud Governance.
• Facilitate design reviews, architecture boards, risk assessments, and cryptographic compliance checks.
• Ensure full traceability of decisions, risks, and technical controls.

3. Deployment, Automation & Documentation

• Deploy and configure AWS KMS, XKS, CloudHSM environments and Thales integrations.
• Automate deployment pipelines using CI/CD, infrastructure-as-code, and DevOps tooling.
• Produce complete documentation (HLD, LLD, runbooks, standard operating procedures, security controls).
• Build dashboards and monitoring for service health, key usage, and compliance adherence.

4. Proof of Concept (POC) & Scalability Validation

• Execute a POC using a real-use case.
• Evaluate performance, scalability, operational flows, and integration reliability.
• Provide recommendations for optimization, security hardening, and operational efficiency.

5. Production Rollout & Service Enablement

• Lead the service transition from POC to production-ready state.
• Ensure the solution meets internal cloud platform criteria:
  • operational readiness
  • monitoring/alerting
  • secure CI/CD pipelines
  • service governance requirements
• Build operational workflows with OSM, Operations, Cloud, and Security teams.
• Drive incident response readiness, DR testing, and change control processes.

6. Knowledge Transfer & Team Upskilling

• Educate and mentor team members on AWS HSM, KMS, XKS, encryption models, and cloud security.
• Conduct training workshops, technical deep-dives, and documentation walkthroughs.
• Help establish an internal competency framework for AWS-based key management systems.

We are seeking an AWS Architecture & Key Management expert to design, validate, and deliver the nextgeneration C3 encryption solution on AWS, equivalent to SGs existing Azurebased service. This role is critical to enabling regulated workloads for platforms in public cloud.

The specialist will be the subject-matter expert (SME) for AWS Key Management Services, XKS (External Key Store), HSM (CloudHSM/Thales), and cloud encryption architectures. They will lead solution design, deployment, automation, validation, and production readinesswhile also upskilling team members and ensuring alignment with SGs internal cloud and security standards. You will work closely with Cloud, OSM, Architecture, and Security Governance teams across Paris, Bangalore, and Bucharest.
