Key Responsibilities

Backend Development

• Implement APIs using TypeScript (Node.js/Apollo Server) and Golang for high-performance services.
• Develop GraphQL subgraphs and REST endpoints, ensuring schema integrity and efficient resolver logic.
• Integrate with API gateways and enforce security standards (OIDC/JWT, role-based access).

System Integration

• Collaborate with other application teams to design and implement API integration patterns.
• Work with Apollo Router for federated GraphQL architectures and schema composition.
• Ensure robust error handling, observability, and performance optimization across services.

Data Layer

• Build and maintain data access layers using GORM (Go) and PrismaORM/TypeORM (TypeScript).
• Implement data integration workflows with relational databases (PostgreSQL) and data warehouses (e.g., Snowflake).
• Optimize queries and ensure secure handling of sensitive data.
• Infrastructure & Cloud
• Deploy and operate services on containerized and serverless platforms (ECS/Fargate, Lambda) across AWS/GCP/Azure.
• Use IaC tools (CDK/Terraform) for environment provisioning and configuration.
• Implement observability practices with distributed tracing (X-Ray/OpenTelemetry), structured logging, and metrics.

Required Skills & Experience

• Languages & Frameworks: Proficiency in Golang and TypeScript; experience with Node.js, Apollo Server, and REST API design.
• ORMs & Data Modeling: GORM, PrismaORM or TypeORM; strong understanding of relational and NoSQL data stores.
• Cloud & Infrastructure: Experience with at least one major cloud provider (AWS/GCP/Azure); familiarity with serverless and container orchestration.
• Security: JWT/OIDC, TLS, IAM/RBAC principles.
• Observability: Logging, metrics, and distributed tracing tools.
• CI/CD: Automated build/deploy pipelines and zero-downtime deployment strategies.

Preferred Qualifications

• Experience with GraphQL federation and Apollo Router.
• Familiarity with messaging systems (SQS/EventBridge or equivalents) and asynchronous processing patterns.
• Exposure to data warehouse integration (Snowflake or similar).
