Wiser Technology designs, builds, and scales complex software systems that power real-world impact. With 500+ engineers and over 25 years of experience in mission-critical environments, we help global organizations turn ambitious ideas into working solutions. Across Europe, MENA, and North America, we combine deep engineering expertise with AI and data to support leading companies in aerospace & defense, automotive, telecom & media, IT, and financial services.
Wiser builds and operates enterprise platforms for large, regulated organisations — multi-channel AI products combining retrieval-augmented generation (RAG), agentic AI, and strict data-isolation requirements, delivered on sovereign cloud infrastructure. We've delivered these in cloud and on-prem; we're now standing up similar platforms on Google Cloud (GCP), and we need a Senior DevOps Engineer to lead that build-out.
You'll own the cloud platform underneath these AI products end-to-end: GKE clusters, GitOps delivery, infrastructure-as-code, CI/CD, observability, and the security posture that regulated and sovereign clients demand. This is a hands-on senior role with platform-design ownership — you'll set patterns the rest of the team builds on.
WHAT YOU WILL DO:
-
Design and operate multi-environment (Dev/QA/Prod) GKE platforms in a hub-spoke model, including networking, service mesh, and multi-tenant / multi-subsidiary isolation.
-
Build Infrastructure-as-Code with Terraform — reusable, reviewable modules for repeatable, client-isolated deployments.
-
Own GitOps delivery (Argo CD / Config Sync) and CI/CD pipelines (Cloud Build / Cloud Deploy / GitHub Actions) with a tag-based, multi-client release strategy.
-
Run the AI-platform layer in production: Vertex AI (Gemini / Model Garden) or OpenAI-compatible model endpoints, vector search, and the RAG/agentic services behind FastAPI backends and Next.js / React Native frontends.
-
Implement observability (Google Cloud Managed Service for Prometheus, Cloud Monitoring, Grafana) and on-call/operational runbooks.
-
Enforce a sovereign-grade security posture — Secret Manager, workload identity, IAM/RBAC, network segmentation, prompt-gateway and inference-isolation controls.
-
Mentor engineers and codify platform patterns as the team scales from Azure into GCP.
WHAT YOU WILL NEED:
-
5+ years DevOps / platform / SRE, with deep Kubernetes in production — ideally GKE (strong AKS/EKS experience welcome and transferable).
-
Strong GCP (or proven cloud-portability: deep Azure/AWS plus eagerness to lead on GCP).
-
Terraform to a senior standard; GitOps (Argo CD or equivalent); modern CI/CD.
-
Container build/runtime, Artifact Registry, networking, and service mesh (Istio / Anthos Service Mesh).
-
Production observability and incident response.
-
A security mindset for regulated / sovereign environments (data residency, isolation, secrets, least-privilege).
NICE TO HAVE:
-
Hands-on running GenAI workloads in production — Vertex AI, RAG pipelines, vector databases, agentic frameworks, LLM gateways.
-
Multi-tenant / multi-customer SaaS platform delivery.
-
Cloud-portability and on-prem reference architectures.
-
GCP Professional certifications (Cloud Architect, DevOps Engineer).
WHAT'S IN IT FOR YOU?
You'll be the founding DevOps engineer for our GCP GenAI platform practice — establishing the patterns, not inheriting them — on flagship sovereign AI products for major enterprise clients.
