About the role

  • Design, develop, and maintain scalable Python-based APIs and backend services using FastAPI and related frameworks.
  • Build, deploy, and optimize production-grade LLM applications using providers such as OpenAI and Anthropic.
  • Design and implement end-to-end RAG solutions, including vector databases, semantic search, retrieval optimization, and chunking strategies.
  • Develop and manage secure, scalable MCP servers and AI infrastructure.
  • Build and orchestrate multi-agent systems to automate complex workflows and business processes.
  • Create, test, and refine prompts, agent instructions, and LLM interactions to improve solution quality and performance.
  • Leverage AI-assisted development tools (e.g., Claude Code, Cursor, GitHub Copilot) to accelerate software delivery and engineering efficiency.
  • Implement event-driven architectures, messaging systems, and real-time communication patterns.
  • Monitor, troubleshoot, and optimize AI and backend systems for performance, reliability, scalability, and security.
  • Collaborate with cross-functional teams to deliver innovative AI solutions and establish engineering best practices.
  • 8+ years of experience developing APIs with Python
  • 2+ years of experience developing and experimenting with LLMs
  • Hands-on, daily use of AI-assisted and agentic coding tools (e.g., Claude Code, Cursor, GitHub Copilot, autonomous coding agents) to write and refactor code, automate workflows, and optimize engineering processes.
  • Strong experience with Python, particularly in building REST APIs using frameworks like FastAPI.
  • Grounding in NLP and machine learning as they relate to building LLM systems
  • Strong experience working with key LLM models APIs (e.g. OpenAI, Anthropic)
  • Experience building, deploying, and securing MCP servers at scale.
  • Understanding of multi-agent systems and their applications in complex problem-solving scenarios.
  • Designing and implementing RAG systems end to end: vector databases, semantic search, retrieval quality, and chunking strategy.
  • Experience with prompt writing for various use cases
  • Experience with generative solutions released to prod, at scale, beyond POCs
  • Proficiency with server-side events, event-driven architectures, and messaging systems.
  • Strong critical thinking and systems thinking skills, with experience debugging, optimizing, and making sound engineering decisions across complex backend systems, not just solving isolated problems.
  • Solid understanding of security best practices for backend systems, including authentication and data protection.

Nice-to-have skills:

  • Experience with LLM guardrails
  • Experience with LLM Frameworks (e.g. LangChain, LlamaIndex)
  • Experience with LLM monitoring and observability
  • Experience developing AI/ML technologies within large and business critical applications
  • Building evaluation into LLM systems: eval harnesses, regression suites, LLM-as-judge, and offline/online quality metrics.

Skills

  • Python
  • FastAPI
  • REST
  • LangChain
