Job DescriptionWe 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.
Qualifications1. 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.
