🗓 Start: ASAP | English-speaking team
In most jobs, security is bolted on.
In this one, you design what "after" looks like before there's an after.
🌍 THE PROJECT
A trusted, sovereign Google Cloud region - operated end-to-end from within Europe by the joint venture between Thales and Google Cloud.
Same Google Cloud power you know (GKE, compute, data, Vertex AI).
European jurisdiction. European operators. Thales-grade cybersecurity.
In the last 6 months alone, the platform:
✅ Achieved a world-first regulatory qualification - IaaS + CaaS + PaaS in a single decision
✅ Named 2026 Google Cloud Partner of the Year - Sovereign Cloud
✅ Runs 3 data centres, 10,000+ devices, H100 GPU clusters in production
Your job: design how every credential, every key, every identity flows through the platform - at regulator-grade.
🛠 WHAT YOU'LL OWN
▸ Operate HashiCorp Vault as a platform-wide secrets service
▸ Maintain Identity Providers (Keycloak, Workspace) and access control
▸ Design credential management for humans and machines
▸ Drive encryption & key management (KMS, HSM, rotation, BYOK/HYOK)
▸ Secure communication patterns - TLS, certificates, trust boundaries, mTLS
▸ Bake security-by-design into every deployment
▸ Lead hardening & compliance - audit evidence, regulator-facing docs
🎯 WHAT WE'RE LOOKING FOR
Must-have:
▸ 7+ years in Security / DevSecOps / Platform Security
▸ Strong hands-on with HashiCorp Vault (or equivalent enterprise secrets management)
▸ Solid IAM / Identity Providers (Keycloak, Workspace)
▸ Hands-on KMS / encryption key management - design and ops
▸ Cloud security best practices, Linux fundamentals
▸ Network security (TLS, proxies, segmentation)
▸ Experience in high-security or regulated environments
Nice to have:
▸ Kubernetes secrets patterns (ESO, sealed-secrets, CSI driver)
▸ Terraform / IaC
▸ SIEM exposure (ELK)
▸ Sovereign cloud experience
💡 WHY THIS ROLE IS DIFFERENT
Identity and secrets ARE the security perimeter of a sovereign cloud.
One leaked key, one misconfigured IDP - and the regulatory posture collapses.
You design the patterns that prevent that. Greenfield, real stakes, real ownership.
🎁 WHAT YOU GET
Competitive package + standard Thales benefits (private medical, meal vouchers, sport). Real ownership in a Bucharest team protecting European critical infrastructure.
👋 SOUND LIKE YOU?
If you've operated Vault at scale, designed KMS rotation strategies in anger, and treat security-by-design as a real engineering discipline - let's talk.
