Maintain and enhance Node.js/TypeScript backend services for a SaaS platform, ensuring uptime, scalability, and high-performance APIs. Optimize MongoDB, implement Redis and job queues, manage AWS infrastructure, enforce security and compliance (GDPR, email handling), document APIs, write tests, and debug production issues.
Responsibilities:
- Maintain and enhance the backend services powering the SaaS platform (Node.js/Express/NestJS with TypeScript).
- Ensure uptime, scalability, and performance of APIs handling campaign generation, template storage, and credit-based billing.
- Optimize MongoDB queries, indexes, and caching strategies for high-performance APIs.
- Implement and manage Redis, job queues, and async workflows.
- Monitor and maintain AWS infrastructure: EC2, S3, CloudWatch, Lambda, SES.
- Implement security best practices: API authentication, rate-limiting, GDPR compliance, email data handling.
- Maintain API versioning and documentation (OpenAPI/Swagger).
- Write unit and integration tests to ensure code quality and reliability.
- Debug and resolve complex production issues efficiently.
Required Skills:
- Strong proficiency in Node.js with TypeScript (Express.js or NestJS).
- Experience with MongoDB, schema design, and ORMs (Mongoose, Prisma).
- Experience with Redis (pub/sub, caching) and job queues (BullMQ/RabbitMQ).
- Familiarity with AWS services: EC2, S3, CloudWatch, SES, Lambda.
- Dockerized microservices and CI/CD pipelines (GitHub Actions, or similar).
- Knowledge of authentication & authorization (JWT, OAuth2, role-based access).
- Basic Logging & monitoring experience (Winston, Pino, Prometheus/Grafana).
- Unit & integration testing experience (Jest, Mocha, Vitest).
- Knowledge of email compliance tools (SpamAssassin, DKIM/SPF/DMARC) is a plus.
Experience:
- 3–5 years in backend development.
Prior experience in SaaS applications, high-traffic APIs, or campaign/marketing platforms is preferred.
