You will be responsible for designing, building, and scaling the API infrastructure to serve recommendations efficiently to our users. This position offers an exciting opportunity to work on cutting-edge technology in a dynamic and collaborative environment.

Key Responsibilities

Collaboration with ML Engineers : Working closely with ML engineers to understand the requirements for recommendation algorithms and integrating them into the REST API infrastructure.

API Development : Building and maintaining RESTful APIs using frameworks like Flask / uWSGI to expose recommendation functionality to the frontend.

Retrievers Implementation : Developing retrievers leveraging ElasticSearch and Pinecone (vector database). Responsibilities include query preparation, managing filters, sorting, pagination, implementing feedback loop, and re-ranking strategies to optimize recommendation accuracy and relevance.

Data Management : Communicating with databases like MongoDB to fetch and save lists, user preferences, and other relevant data necessary for generating recommendations. This includes designing efficient database schemas, implementing data access logic, and ensuring data consistency and integrity.

Performance Optimization : Optimizing API performance for scalability and responsiveness, especially when dealing with compute-intensive requests. This involves caching strategies with Redis, query optimization, and parallel processing techniques. Implementing tools to facilitate monitoring of recommendations accuracy over time.

Testing and Quality Assurance : Writing unit tests, integration tests, and end-to-end tests to ensure the reliability and correctness of the API functionalities. This includes testing different scenarios, error handling, and edge cases.

Documentation and Communication : Documenting API endpoints, parameters, and usage guidelines for developers (front-end) and clients (using API). Communicating effectively with stakeholders, including ML engineers, product managers, and other team members, to gather requirements, provide updates, and address issues.

Bachelor's degree in Computer Science or Engineering.
