Sr. Backend Software Engineer (26-00005) -

We are looking for a highly skilled backend developer to design, build, and maintain distributed systems and APIs that power mission-critical services. This role focuses on hands-on development with TypeScript and Golang, leveraging modern frameworks and cloud-native architectures to deliver secure, scalable, and resilient solutions.

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.
