AI-Driven Development : Integrate machine learning models (AI / ML) into production microservices.

Data Integration : Architect and develop robust data synchronization with experience in Snowflake integrations (e.g., using Snowflake Python Connector or ORM extensions) to handle large-scale analytical and transactional data flows.

Data Persistence : Implement and optimize data models and persistence layers using modern Database ORMs (e.g., SQLAlchemy, SQLModel) for relational and NoSQL databases.

3. Engineering Quality & Best Practices

Code Quality : Define and enforce organization-wide Code Base Best Practices and rigorous Code Quality standards, including performance, security, and maintainability.

Testing : Establish comprehensive Unit Test Cases , integration tests, and end-to-end testing strategies to ensure high coverage and reliability across all services.

Mentorship : Provide technical leadership, mentorship, and code reviews to mid and senior-level engineers, fostering a culture of technical excellence.

Required Qualifications

Experience : 8+ years of professional software development experience, primarily focused on backend systems using Python.

Core Backend : Expert proficiency in Python and developing high-performance RESTful APIs, with specific, demonstrable experience using FastAPI .

API Standards : Deep understanding and practical experience defining APIs using the OpenAPI Specification (OAS) , including tooling for validation and documentation.

Architecture : Proven history of designing, deploying, and maintaining systems built on Microservice Architectures .

Data Layer : Expertise with relational databases and using advanced Database ORM features for complex query optimization and schema migrations.

Workflow Systems : Experience defining, implementing, and managing complex business logic using step-based, state-driven, or declarative workflow systems (e.g., orchestration tools, custom state machines).

Cloud & Data : Strong experience working with cloud environments (AWS, GCP, or Azure) and significant experience integrating systems with Snowflake .

Preferred Qualifications (Nice-to-Haves)

Experience in integrating AI-Driven Development principles into software lifecycles.

Experience with AI Editors (Cursor, Windsurf etc) for coding
