About Our Opportunity

We are seeking a seasoned Backend Engineer who can architect, build, and maintain scalable, secure, and high-performance backend systems.

This role is ideal for someone who thrives in a fast-paced, collaborative environment and wants to take ownership of building robust backend services that directly impact product performance and user experience.

Main Responsibilities:

  • Backend Development: Develop, scale, and maintain backend services and microservices using technologies such as Node.js, Express.js, and NestJS (experience with Go, Python, or Java is a plus).
  • System Design & Architecture: Design and implement reliable and maintainable backend architectures. Apply principles of modular architecture, event-driven systems, and microservices where appropriate.
  • API Development: Create and maintain RESTful APIs and GraphQL endpoints for efficient frontend-backend communication, with a focus on performance, versioning, and security.
  • Database Management: Design and optimize schemas for relational databases like PostgreSQL, MySQL, as well as NoSQL databases like MongoDB, Redis, or DynamoDB.
  • Performance Optimization: Identify and resolve bottlenecks in APIs, queries, and backend logic. Use tools and strategies for load handling, caching (e.g., Redis), and horizontal scaling.
  • Code Quality & Best Practices: Write clean, testable, and maintainable code. Participate in code reviews and promote engineering best practices.
  • Testing & Debugging: Write unit and integration tests (e.g., using Jest, Mocha) and debug production issues efficiently.
  • CI/CD & DevOps Collaboration: Work with the DevOps team to integrate backend services into CI/CD pipelines and automate deployments.
  • Cross-Functional Collaboration: Collaborate with frontend engineers, designers, product managers, QA, and DevOps to ship features in a collaborative agile environment.

Essential Skills & Experience:

  • 4+ years of hands-on backend development experience in a product or platform team.
  • Strong experience with Node.js and TypeScript; familiarity with Express.js, NestJS, or similar frameworks.
  • Solid knowledge of relational (PostgreSQL, MySQL) and NoSQL (MongoDB, Redis, DynamoDB) databases.
  • Proficient in designing and building scalable RESTful APIs; working knowledge of GraphQL is a plus.
  • Experience working with Docker, Git, and CI/CD tools such as GitLab CI, GitHub Actions, or Jenkins.
  • Exposure to cloud platforms like AWS, or Azure, and services like EC2, S3, Lambda, API Gateway, CloudWatch, etc.
  • Understanding of backend security principles including authentication, encryption, and API protection.
  • Experience with performance monitoring, debugging, and observability tools.
  • Familiarity with event-driven systems using Kafka, RabbitMQ, or SQS/SNS is a bonus.
  • Strong problem-solving skills and ability to troubleshoot issues in distributed systems.

Nice to Have:

  • Experience with Go, Python, or Java for building microservices.
  • Exposure to GraphQL, Apollo Server, or gRPC.
  • Familiarity with Kubernetes, and serverless architectures.
  • Knowledge of Infrastructure as Code tools like Terraform.
