About the Role

We are seeking a Senior GCP & Apigee X Engineer to join a specialized platform team building a secure, enterprise-grade AI Gateway to serve Generative AI capabilities across the organization. In this hands-on engineering role, you will take ownership of design, build, and production-readiness across Apigee X and Google Cloud Platform.

Responsibilities

  • ● 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.

Requirements

  • ● Strong hands-on experience designing, engineering, and operating Apigee X (or Apigee Edge) in enterprise environments.
  • ● Deep experience across GCP platform services (IAM, Cloud KMS, Secret Manager, Cloud Run, Cloud Logging) and cloud networking (VPC, Private Service Connect, ILB, Private Service Access).
  • ● Practical experience integrating Vertex AI or managed GCP ML services through secure enterprise platform paths.
  • ● Strong mastery of REST, OpenAPI, OAuth 2.0, OIDC, JWT validation, and federated identity integration.
  • ● Deep proficiency with Terraform and modern GitLab CI/CD pipelines.

Nice to Have

  • ● Exposure to Apigee LLM policies (token quotas, prompt limits, model operation groups) or Google Cloud Model Armor / Cloud DLP.
  • ● Experience with enterprise observability toolsets (Dynatrace, ELK, or Cortex XSIAM) or BigQuery log analysis.
