Senior GCP & Apigee X Engineer

Job description

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 . You will design API proxies and shared flows, establish secure private connectivity to GCP Vertex AI , automate platform infrastructure with Terraform and GitLab CI/CD, and build robust telemetry to support FinOps token attribution and operational observability. We are open to a Permanent or Contract option for this role. So please apply if you are looking for either. 1. Apigee X & AI Gateway Development 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. 2. GCP Foundation & Secure Connectivity 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. 3. Automation, FinOps & Observability 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. 4. Production Readiness & Operations 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. Essential: Apigee X Expertise: Strong hands-on experience designing, engineering, and operating Apigee X (or Apigee Edge) in enterprise environments. GCP Infrastructure & Security: 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). Vertex AI Integration: Practical experience integrating Vertex AI or managed GCP ML services through secure enterprise platform paths. Identity & Security Protocols: Strong mastery of REST, OpenAPI, OAuth 2.0, OIDC, JWT validation, and federated identity integration. Infrastructure as Code (IaC): Deep proficiency with Terraform and modern GitLab CI/CD pipelines. Desirable: 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 analytics. Familiarity with FinOps cost-allocation labeling, billing exports, or consumer-level chargeback models for AI workloads. Exposure to cross-cloud AI gateway patterns (e.g., AWS Bedrock, AWS SigV4) or Model Context Protocol (MCP) / agentic AI frameworks. Why NCS?
