Job Description

We seek an exceptional developer who goes beyond coding to manage and orchestrate a full "Build+Run" ecosystem. You will be a key driver in transforming our architecture from monolithic applications to a resilient, distributed, event-driven system on Google Cloud Platform (GCP). This role demands expertise inApigee for robust API governance,Node.js for high-performance backend services, andPub/Sub for asynchronous service decoupling. Success will be measured by continuous optimization of infrastructure for cost and performance usingGKE/Cloud Run and automated delivery viaCloud Build andTerraform.

Key Responsibilities

High-Performance Node.js Backend Engineering

Asynchronous Architecture: Design and implement non-blocking, event-driven services using Promises andasync/await to ensure high concurrency and prevent event loop blocking.
Performance & Efficiency: Optimize for low latency by utilizing theCluster module for multi-core processing and employinglazy loading of dependencies to minimize serverless cold starts (e.g., in Cloud Run).
Security Implementation: Secure APIs against threats like SQL injection and XSS through strict input validation (e.g.,express-validator) and implementrate limiting to mitigate DoS attacks.
Data Transfer Optimization: Configure middleware for Gzip/Brotli compression of HTTP responses to significantly reduce payload size and improve transfer speed.

API Governance and Management (Apigee)

API Proxy Design: Develop Apigee ProxyEndpoints and TargetEndpoints to decouple frontend client applications from underlying backend service implementations.
Automated API Lifecycle: Integrate API proxy deployment, unit testing, and integration testing directly into the Continuous Integration/Continuous Deployment (CI/CD) pipeline.
Traffic Control & Security: Implement advanced traffic management policies (SpikeArrest,Quotas) and enforce robust security protocols (OAuth 2.0,JWT,SAML) for authorization and authentication.
Analytics & Monetization: Configure API Product bundles for potential monetization models and generate custom reports to monitor key metrics like traffic patterns, latency percentiles, and error rates.

Cloud-Native Architecture (GKE & Cloud Run)

Resource Autoscaling: Strategically configureHorizontal Pod Autoscalers (HPA) for CPU-based scaling andVertical Pod Autoscalers (VPA) for resource recommendation, ensuring configuration compatibility.
Cost Optimization: LeverageSpot VMs for fault-tolerant, stateless services and batch workloads to achieve up to 90% savings on compute costs.
Container Security: Prioritize building minimal, secure container images and maintain deterministic builds to enhance security posture and prevent vulnerability injection.

Event-Driven Architecture (Pub/Sub)

System Resilience: Drive the adoption of asynchronous Pub/Sub messaging to replace synchronous service-to-service communication, thereby increasing overall system resilience.
Message Reliability: Implementdead-letter topics to quarantine and facilitate debugging of unprocessable messages, and useexactly-once delivery where financial or state integrity is critical.
Real-Time Processing: Design and build data pipelines that consume events from Pub/Sub and process them in real-time usingDataflow for analytics stored in BigQuery.

DevOps & Infrastructure as Code (Terraform)

Modular IaC: Provision all necessary GCP resources (e.g., Pub/Sub subscriptions, GKE clusters, Apigee organizations) using reusable Terraform modules, managing state securely via remote GCS backends for collaborative development.
GitOps CI/CD: Implement Cloud Build pipelines triggered by Git commits, integrating static analysis, vulnerability scanning (Container Analysis), and binary authorization checks before deployment.
Credential Security: Eliminate hardcoded secrets by integratingSecret Manager into both Terraform provisioning and application runtime environments.

Required Technical Expertise

Core Language: Expert proficiency inNode.js, with a deep, practical understanding of the event loop, streams, and memory management.
API Platform: Extensive hands-on experience withGoogle Cloud Apigee, covering policy configuration, complex fault handling, and developer portal administration.
Database & State Management (Stateless Focus):
- Proven ability to architectstateless applications, offloading session/state data to external, dedicated stores.
- Proficiency in usingMemorystore (Redis) for high-speed, ephemeral caching and session storage.
- Experience withFirestore orCloud SQL for durable, transactional data and user preferences, including the use of connection pooling.
DevOps Tooling: Mastery ofCloud Build,Terraform, andArtifact Registry.
Testing: Expertise in black-box API testing, comprehensive unit testing and load testing methodologies.

Preferred Qualifications

Certification: Google Professional Cloud Developer or Professional Cloud Architect certification.
Advanced Networking: Familiarity with VPC Service Controls, Private Service Connect, and Shared VPCs.
Service Mesh: Experience with Istio or Cloud Service Mesh for managing traffic, security, and observability.
Observability: Proficiency in instrumenting applications forCloud Trace,Cloud Logging, andCloud Monitoring to minimize Mean Time to Diagnosis (MTTD).
Ownership Mentality: The ability to manage a feature's complete lifecycle, from initial design through to production deployment, monitoring, and incident response ("Build+Run").
AI-Assisted Development: Comfortable with and actively uses AI tools (e.g., Gemini Code Assist) to accelerate boilerplate generation, allowing focus on complex architectural challenges.
