Backend Engineer

We are seeking a skilled Backend Engineer to design, develop, and maintain the server-side logic of our applications. This role is critical for building robust, scalable systems that can handle high volumes of traffic and complex data processing.

The ideal candidate has a deep understanding of the event loop, asynchronous programming, and the design patterns needed to manage concurrency effectively. You will also be responsible for designing and implementing solutions using message queues to ensure our services are decoupled, resilient, and capable of processing tasks asynchronously.

Key Responsibilities

• Design & Develop APIs: Build, and maintain efficient, reusable, and reliable server-side applications and RESTful APIs using
• Asynchronous Processing: Architect and implement solutions using message queuing systems (like RabbitMQ, Kafka, or AWS SQS) for asynchronous tasks, inter-service communication, and event-driven architectures.
• Manage Concurrency: Write high-performance, non-blocking code, leveraging your deep understanding of the event loop, promises, async/await, and patterns for handling concurrency (e.g., worker threads, connection pooling).
• Database Management: Integrate with and manage various databases, including NoSQL (like MongoDB, Redis) and SQL (like PostgreSQL, MySQL).
• Code Quality: Write clean, testable, and maintainable code. Champion best practices by writing unit and integration tests using frameworks like Jest, Mocha, or Chai.
• Collaboration: Work closely with front-end developers, product managers, and other engineers to deliver new features and solutions.
• Scalability & Performance: Proactively identify and resolve performance bottlenecks, ensuring our application remains fast and reliable as we scale.
• DevOps: Participate in the deployment and maintenance of applications, using Docker, CI/CD pipelines, and cloud services.

Skills and Qualifications

Required (Must-Haves):

• Experience: 3+ years of professional experience in backend development.
• Core Skill: Strong proficiency in and its core principles (event loop, non-blocking I/O, streams).
• Concurrency: Proven experience designing and debugging concurrent systems in You must be able to explain how you've handled race conditions, managed asynchronous flows at scale, and optimized I/O operations.
• Queues: Demonstrable, hands-on experience with at least one message queue system (RabbitMQ, Kafka, AWS SQS, Google Pub/Sub, etc.).
• Frameworks: Proficiency with a framework like , NestJS, or Fastify.
• Databases: Strong experience with both NoSQL (MongoDB, Redis) and SQL (PostgreSQL, MySQL) databases, including data modeling and query optimization.
• APIs: Expertise in designing, building, and documenting RESTful APIs.
• Testing: Familiarity with testing frameworks (Jest, Mocha) and a commitment to code quality.
• Version Control: Proficient with Git and Git-based workflows.

Preferred (Nice-to-Haves):

• TypeScript: Strong professional experience with TypeScript is highly preferred.
• Cloud & DevOps: Experience with cloud platforms (AWS, GCP, or Azure), especially serverless functions, and containerization technologies (Docker, Kubernetes).
• Microservices: Understanding of microservice architecture principles and best practices.
• CI/CD: Experience setting up and maintaining CI/CD pipelines (e.g., GitHub Actions, GitLab CI, Jenkins).
• Additional mastery of other languages such as Rust, Golang, C#, Java.
