• AI & LLM Integration: Work closely with cross-functional engineering and data teams to embed predictive analytics, smart financial categorization, and LLM-driven features into customer-facing applications.
• API Architecture: Design secure, predictable, and well-documented RESTful and gRPC APIs to connect internal microservices and external fintech ecosystem partners.
• Database Management: Optimize queries, schemas, and indexing strategies for both relational databases (PostgreSQL) and caching systems (Redis).
• Code Quality & Best Practices: Participate in rigorous code reviews, write comprehensive unit/integration tests, and contribute to internal architectural standards.

Requirements

• Experience: 3+ years of professional software engineering experience with a strong focus on Python.
• Framework Proficiency: Deep hands‑on experience with FastAPI, asynchronous programming in Python (asyncio), and related package ecosystems.
• Database Skills: Solid understanding of SQL (PostgreSQL) and NoSQL solutions, including query optimization, handling high‑concurrency connections, and practical experience with vector databases (e.g., Pinecone, Milvus, or Weaviate) for semantic search and AI retrieval architectures.
• Infrastructure & Tools: Comfortable working with Docker, CI/CD pipelines (GitHub Actions/GitLab CI), and cloud services (AWS or GCP).
• Fintech Mindset: Basic understanding of financial architectures, transaction flows, encryption standards, or crypto‑fiat transactional systems.
• Team player: Exceptional problem‑solving skills and a strong capacity to collaborate in a distributed, remote‑first setup.
• Language Skills: Professional proficiency in English (B2+).
