Job Description:

Python Backend Engineer - FastAPI & Agentic AI

Roles & Responsibilities:

• Backend Development & API Engineering
  • Design, develop, optimize, and maintain asynchronous backend services using Python and FastAPI.
  • Build high-performance APIs capable of handling high-volume requests with minimal latency.
  • Implement non-blocking operations using asyncio and Uvicorn.
  • Manage database connection pools and optimize backend performance.
• LLM Evaluation & Regression Testing
  • Develop deterministic LLM evaluation and regression testing pipelines.
  • Validate model consistency, output quality, and structured response schemas using Pydantic.
  • Monitor agent stability and identify inconsistencies in AI-generated responses.
• Multimodal Data Processing
  • Develop data ingestion pipelines for processing text, images, and videos.
  • Handle media decoding, validation, extraction, and processing of unstructured data.
  • Build reliable pipelines to transform multimodal inputs into structured data.
• Agentic AI & Workflow Development
  • Design and implement stateful, graph-based agent workflows.
  • Develop multi-step agent execution processes involving tool calling and state reconstruction.
  • Handle hallucinations, prevent infinite loops, and improve agent reliability.
  • Implement context-window and token management, including dynamic context pruning, summary compression, and retrieval optimization.
• Data Ingestion & Quality Pipelines
  • Build data extraction, validation, filtering, and cleansing pipelines.
  • Convert raw web data into structured, high-quality inputs.
  • Develop high-volume ingestion systems using request queues and API rate-limit handling.
  • Implement failure management and Redis-based backpressure control.
• Testing & Code Quality
  • Develop comprehensive unit and integration test suites.
  • Follow test-driven development practices.
  • Write clean, modular, documented, and maintainable code.
  • Focus on simplicity, readability, performance, and reliability.

Required Skills & Qualifications:

• 3-5 years of experience in Python Backend Development.
• Strong hands-on experience with Python, FastAPI, asyncio, and Uvicorn.
• Experience building asynchronous and non-blocking backend services.
• Understanding of database connection pooling and API performance optimization.
• Experience with multimodal data processing, including images, videos, media buffers, and unstructured data.
• Hands-on experience with Pydantic and structured data validation.
• Strong understanding of data extraction, parsing, filtering, and cleansing.
• Experience with unit testing, integration testing, and Test-Driven Development (TDD).
• Practical experience with Redis, API rate limiting, request queuing, and high-volume data ingestion.
• Experience building production AI/Agentic AI systems.
• Understanding of tool calling, hallucination handling, infinite-loop prevention, and context-window management.
• Strong problem-solving and debugging skills.

Ideal Candidate Profile:

• Strong backend engineering fundamentals with practical Python development experience.
• Experience building scalable, asynchronous backend infrastructure.
• Exposure to production-grade LLM applications and Agentic AI workflows.
• Ability to handle complex data processing and ingestion requirements.
• Passion for writing simple, efficient, testable, and maintainable code.
