Location : Gurugram

Experience : 4+ years

Team : Engineering (Backend)

Type : Full-time

What Youll Do :

As an SDE2 Backend Engineer, youll take end-to-end ownership of feature modules, enforce engineering best practices, and mentor junior developers. Youll help us transition from a modular monolith to a microservices-based architecture, ensuring separation of concerns, scalability, and long-term maintainability.

Core Responsibilities :

- Own the design, implementation, and scaling of backend modules (NestJS + PostgreSQL)

- Architect and build stateless, testable, and modular APIs for :

- Amazon Ads (SP, SB, SD), SP-API, campaign manager, catalog health

- Lead data ingestion and cron orchestration for large-scale sync jobs

- Define internal service boundaries and interfaces in preparation for microservices

- Enforce high standards for code reviews, error handling, and observability

- Collaborate on service extraction strategy identify what to decouple, how to deploy, and how to manage communication across services

- Support containerized deployment workflows (Docker, EC2, SSM Parameter Store)

Team Leadership & Engineering Practices :

- Mentor SDE1s and interns, helping them improve technically and professionally

Champion practices like :

- Explicit logging and monitoring

- Structured error handling and retries

- Type-safe and DRY API contracts

- Propose tech debt cleanups and refactoring initiatives as we scale

- Contribute to on-call readiness and help improve our alerting stack (GoAlert, logs, metrics)

What Were Looking For :

Required :

- 4+ years of backend engineering experience

- Proficient in NestJS, TypeScript, PostgreSQL, and TypeORM

- Experience with distributed system principles (even in a monolith)

- Strong understanding of API design, data modeling, and scalable architecture

- Proactive in code quality, documentation, and mentoring

- Comfortable with Docker, EC2, and SSM Parameter Store

- Experience with microservice design patterns

- Familiarity with message queues, service discovery, and API gateways

- Worked with Amazon Ads API or SP-API

- Exposure to ETL pipelines, cron scheduling, or data sync reliability

Tech Stack :

- Backend : NestJS, Node.js, TypeORM, PostgreSQL, MongoDB

- Infra : Microservices architecture, Docker, EC2, AWS Systems Manager Parameter
Store, KMS

- Data : Amazon Ads API, SP-API, cron-based syncs

- Monitoring : GoAlert, Cloudwatch

- Tooling : GitHub, Postman, VSCode
