Backend API FDE 1 (Lead APIs)

Role : Backend API FDE 1 (Lead APIs),

Skills: Kubernetes,Containers,Next JS,Cloud Platform Management (AWS, Azure, GCP)

Job Summary: Looking for Typescript API developers to design and build cloud-native, API-first, multi-tenant backend services in Node.js/TypeScript, with AI as a first-class collaborator across the full software development lifecycle. You will deliver spec-driven services on AWS ECS that safely serve multiple tenants and white-label brands, work across relational and NoSQL data stores, and help the Software Engineering Practice extend best practices for AI-SDLC. Skill: Nest.JS, (Nest.Js for Microservices development) Container and Kubernetes Cloud- AWS, Azure, GCP (Any two) Design Patterns like Solid, OOPS Spec-driven Development (Preferred Claude or any other AI tools)

Job Description:
Core Skills

• Design, build, and operate production Node.js/TypeScript APIs following cloud-native, 12-factor, and API-first principles
  
• Design and implement multi-tenant services with appropriate tenant isolation across request, data, credential,and infrastructure layers; support white-label configurations without cross-tenant leakage
  
• Author OpenAPI / AsyncAPI / JSON Schema contracts as the source of truth; drive generation of code, clients,contract tests, and documentation from specs
  
• Apply AI across the SDLC requirements analysis, design, code generation, test authoring, review, and documentation using tools such as Claude Code, Copilot, and Cursor
  
• Model and implement data persistence across RDBMS and NoSQL with tenant-aware schemas, partitioning, and access patterns; own indexing, migrations, and query optimization
  
• Containerize services and deploy to AWS ECS (Fargate/EC2) with ECR, ALB, Secrets Manager, CloudWatch, and IAM least-privilege
  
• Implement resilience and cross-cutting concerns — authN/authZ, tenant context propagation, validation,structured logging, tracing, metrics, retries, circuit breakers, idempotency
  
• Support modernization of legacy monoliths to decoupled, multi-tenant, API-first services using strangler-fig and parallel-run patterns with zero-downtime cutover
  
• Write unit, integration, and contract tests; contribute to CI/CD and progressive delivery
  
• Participate in code and design reviews; mentor peers as applicable
  

Must Haves:

• Hands-on experience building production Node.js backend services and REST/event-driven APIs (Express, Fastify,or NestJS)
  
• Strong proficiency in TypeScript
  
• Multi-tenant SaaS design experience — tenant isolation strategies (shared, siloed, hybrid), tenant context handling, and noisy-neighbor mitigation
  
• Cloud-native design — stateless services, externalized config, health checks, horizontal scale, observability
  
• Production experience with AWS ECS — Docker, task definitions, service configuration, ALB integration
  
• Spec-driven / contract-first development using OpenAPI and/or JSON Schema
  
• Applied AI across the SDLC — coding, testing, review, documentation
  
• Ability to work with both RDBMS and NoSQL — tenant-aware data modeling, indexing, query tuning; hands-on with PostgreSQL and/or MongoDB
  
• API security — OAuth2/OIDC, JWT, secrets management, OWASP API Top 10
  
• Git, CI/CD, and trunk-based development
  

Preferred (Good to have)

• AWS certification (Developer Associate, Solutions Architect Associate, or higher)
  
• Event-driven architecture using SQS, SNS, EventBridge, or Kafka
  
• Infrastructure-as-Code (Terraform, AWS CDK)
  
• White label / configurable product experience across multiple brands
  
• Observability stacks (OpenTelemetry, Datadog, New Relic)
  
• Monolith-to-microservices migrations with zero-downtime cutover
  
• Exposure to EKS/Kubernetes and service mesh
  
• GraphQL or gRPC alongside REST
  
• Caching (Redis/ElastiCache) and search (OpenSearch/Elasticsearch)
