● Lead the design and implementation of database schemas for relational (e.g., PostgreSQL) and NoSQL databases, with a strong emphasis on Graph Databases (Neo4j).

● Model complex data relationships and structures effectively, particularly leveraging graph data modeling principles where appropriate.

● Write efficient, optimized database queries (SQL, Cypher, potentially others).

● Develop and maintain data models, ensuring data integrity, consistency, and security.

● Optimize database performance through indexing strategies, query tuning, caching mechanisms, and schema adjustments.

● Collaborate closely with product managers, frontend developers, and other stakeholders to understand data requirements and translate them into effective database designs.

● Implement data migration strategies and scripts as needed.

● Integrate various databases seamlessly with Python backend services using ORMs (like SQLAlchemy, Django ORM) or native drivers.

● Write unit and integration tests, particularly focusing on data access and manipulation logic.

● Contribute to architectural decisions, especially concerning data storage, retrieval, and processing.

● Stay current with best practices in database technologies, Python development, and backend systems.

Minimum Qualifications:

● Bachelor's degree in Computer Science, Engineering, Information Technology, or a related field, OR equivalent practical experience.

● 3-4 years of professional software development experience with a primary focus on Python backend development.

● Strong proficiency in Python and its standard libraries.

● Proven experience with at least one major Python web framework (e.g., Django, Flask, FastAPI).

● Demonstrable, hands-on experience designing, implementing, and managing relational databases (e.g., PostgreSQL).

● Experience with at least one NoSQL database (e.g., MongoDB, Redis, Cassandra).

● Solid understanding of data structures, algorithms, and object-oriented programming principles.

● Experience designing and consuming RESTful APIs.

● Proficiency with version control systems, particularly Git.

● Strong analytical and problem-solving skills, especially concerning data modeling and querying.

● Excellent communication and teamwork abilities.

Preferred (Good-to-Have) Qualifications:

● Graph Database Expertise:

○ Significant, demonstrable experience designing and implementing solutions using Graph Databases (Neo4j strongly preferred).

○ Proficiency in graph query languages, particularly Cypher.

○ Strong understanding of graph data modeling principles, use cases (e.g., recommendation engines, fraud detection, knowledge graphs, network analysis), and trade-offs.

● Advanced Database Skills:

○ Experience with database performance tuning and monitoring tools.

○ Experience with Object-Relational Mappers (ORMs) like SQLAlchemy or Django ORM in depth.

○ Experience implementing data migration strategies for large datasets.

● Cloud Experience: Familiarity with cloud platforms (e.g., AWS, Azure, Google Cloud Platform) and their managed database services (e.g., RDS, Aurora, Neptune, DocumentDB, MemoryStore).

● Containerization & Orchestration: Experience with Docker and Kubernetes.

● Asynchronous Programming: Experience with Python's asyncio and async frameworks.

● Data Pipelines: Familiarity with ETL processes or data pipeline tools (e.g., Apache Airflow).

● Testing: Experience writing tests specifically for database interactions and data integrity.

What We Offer:

● Challenging projects with opportunities to work on cutting-edge technologies especially in the field of AI.

● Competitive salary and comprehensive benefits package.

● Opportunities for professional development and learning (e.g., conferences, courses, certifications).

● A collaborative, innovative, and supportive work environment.
