Onsite Experience: 3-5 Years

Role Overview: We are seeking a versatile, high-velocity Python full stack + AI/ML Developer (MERN
knowledge is a solid plus) who embraces modern AI-assisted coding (Claude, Cursor, GitHub
Copilot) to reduce traditional 4-month development cycles down to 1 month. You will take end-to-
end ownership of critical banking and business applications, from architecting fault-tolerant backend
databases and event-driven microservices to deploying server-side Python UIs and training Small
Language Models (SLMs).

AI-Driven Rapid Development: Leverage AI coding assistants (Copilot, Claude, Cursor) to rapidly
prototype, develop, and deploy enterprise-grade applications. Rigorously review and validate AI-
generated code for security, logic, and scalability.
Full Stack Python Engineering: Design and build robust backend APIs (FastAPI, Django) and




interactive client-facing dashboards using Python-native UI frameworks (Streamlit, Dash, or Django
templates). Knowledge of the MERN stack is a strong plus.
High-Scale FinTech Architecture: Architect event-driven systems (Kafka/RabbitMQ) and optimize
complex databases (PostgreSQL, MySQL, MongoDB, Elasticsearch, Neo4j) to handle high-volume
financial transactions.
Data Integrity & Consistency: Implement Transactional Outbox patterns, idempotency keys, and
Redis caching to ensure zero financial data loss, accurate event replays, and ultra-low latency during
real-time reconciliations.
Security & Compliance: Enforce strict data security standards (DPDP Act compliance). Implement
AES encryption, JWT/OAuth2 authentication, PII masking, and secure secret management (AWS
KMS/Fortanix) to protect sensitive banking data.
AI/ML Integration: Develop and deploy multi-agent workflows (LangChain, LangGraph), RAG
pipelines,
