  • Develop and integrate RESTful or GraphQL APIs to serve front-end applications and external clients.
  • Design and optimize database schemas (SQL and NoSQL) to ensure data integrity and query performance at scale.
  • Collaborate with frontend developers, product managers, and designers to translate requirements into robust technical solutions.
  • Troubleshoot production issues, identify bottlenecks, and drive performance optimizations across the application stack.
  • Write comprehensive unit and integration tests to ensure high code quality and system stability.

  • Deep understanding of API design principles (REST, GraphQL) and web standards.
  • Strong experience with relational databases (PostgreSQL, MySQL) and familiarity with NoSQL stores.
  • Knowledge of distributed systems, caching mechanisms (Redis/Memcached), and asynchronous messaging (Kafka/RabbitMQ).
  • Familiarity with containerization (Docker) and basic CI/CD workflows.

Even better if you have

  • Experience working on high-traffic, customer-facing web applications.
  • A strong grasp of system design concepts and architectural patterns (e.g., Microservices, DDD).
  • Familiarity with cloud computing platforms (AWS, GCP, or Azure) and serverless technologies.
  • Experience optimizing legacy codebases for performance and maintainability.

You will thrive in this role if

  • You are passionate about shipping high-quality code that directly solves user problems.
