Role Overview We are looking for a Senior Software Engineer with 5+ years of experience to build and enhance AI-driven applications and platforms. This role involves prompt engineering, Python backend development (including FastAPI), data handling, and contributing to multiple AI initiatives and proof-of-concepts across the organization. The ideal candidate is hands-on, comfortable with ambiguity, and enjoys working on real-world problems using AI. Key Responsibilities • • Design, develop, and maintain Python-based AI applications and services, including FastAPI-based microservices and APIs. • Perform prompt engineering and prompt optimization for LLM-based workflows • Build reliable pipelines for processing unstructured and semi-structured data • Develop and integrate RESTful APIs and backend services supporting AI workflows using FastAPI and related tooling. • Work with databases and data stores to persist, validate, and analyze AI outputs • Implement robust error handling, validation, and retry mechanisms in API and service layers. • Collaborate with architects and stakeholders to translate requirements into scalable, performant solutions • Contribute to AI proof-of-concepts, experiments, and rapid prototypes • Optimize solutions for performance, reliability, and cost, including async and high-load API patterns. • Write clean, maintainable, and well-documented code with appropriate API documentation (e.g., OpenAPI/Swagger via FastAPI). Required Skills & Experience • • 5+ years of professional experience in Python development • Strong understanding of AI/ML concepts, especially LLM-based systems • Experience with prompt engineering and model interaction patterns • Solid background in backend development and API design, with hands-on experience building production APIs using FastAPI. • Experience working with databases (SQL and/or NoSQL) • Familiarity with asynchronous programming patterns and scalable API architectures (as commonly used with FastAPI). • Strong problem-solving and debugging skills • Ability to work independently and take ownership of deliverables Nice to Have • • Experience building AI-driven or data-intensive systems • Exposure to cloud-based environments (AWS/GCP/Azure) • Familiarity with asynchronous or distributed processing (e.g., task queues, event-driven architectures) • Experience with rapid prototyping and experimentation • Understanding of evaluation, accuracy, and quality metrics for AI systems • Experience integrating FastAPI services with frontend applications or other backend systems. What We’re Looking For • • Someone who can think beyond prompts and build complete systems • Comfortable working on multiple AI initiatives, not just a single project • Strong engineering fundamentals with a practical AI mindset • Bias toward execution and ownership, including designing and owning API contracts and service reliability.
