Senior GCP & Apigee X Engineer

NCS Group AustraliaSydneyOn-siteFull-time30 Sept 2026

NCS Australia is seeking a Senior GCP & Apigee X Engineer to join a specialized platform team building a secure, enterprise-grade AI Gateway for Generative AI capabilities. The role involves hands-on design, build, and production-readiness across Apigee X and Google Cloud Platform, including API proxies, secure connectivity to Vertex AI, Terraform automation, and observability. Requires strong expertise in Apigee X, GCP infrastructure, identity protocols, and Infrastructure as Code.

What you'll do

Design, build, and maintain Apigee X API proxies, shared flows, XML policies, JavaScript callouts, API products, and key-value configurations.
Implement core gateway capabilities: OAuth 2.0/OIDC authentication, token exchange, model-based routing, request/response transformations, rate-limiting, token quotas, and fault handling.
Translate consumer-facing payload contracts into provider-specific schemas for Generative AI models.
Build and manage GCP platform infrastructure supporting gateway paths: IAM, Cloud KMS, Secret Manager, Cloud Run, Cloud Logging, and DNS.
Implement private, secure networking between Apigee X, Vertex AI, and enterprise networks using Private Service Connect (PSC), Internal Load Balancers (ILB), and Service Perimeters.
Configure Workload Identity, federated authentication (Entra ID/UAM), and least-privilege service-account mappings for machine-to-machine workloads.
Automate platform delivery using Terraform and GitLab CI/CD pipelines for repeatable promotion across Dev, Test, and Production environments.
Generate structured telemetry for request volumes, latency, error rates, model quotas, prompt token usage, and guardrail enforcement.
Support FinOps workflows by ensuring detailed usage data reconciles cleanly across consumer apps, model providers, and GCP billing exports.
Lead technical testing phases (SIT/UAT, OAT, penetration testing remediation, performance validation, and cutover execution).
Produce comprehensive operational runbooks, service-desk knowledge base articles, and handover materials for steady-state BAU support.
