About the Job

Requirements

  • Three to six years of experience in software engineering, AI engineering, or Generative AI application development.
  • Hands-on experience building LLM-powered applications using Python.
  • Strong understanding of LLM concepts, prompt engineering, RAG architecture, AI agent workflows, and vector search concepts.
  • Experience with agent frameworks such as LangGraph, LangChain, LlamaIndex, Semantic Kernel, or CrewAI.
  • Experience integrating LLM applications with REST APIs, databases, and enterprise systems.
  • Knowledge of vector databases, embeddings, semantic search, and retrieval optimization techniques.
  • Experience developing production-quality Python applications using FastAPI or similar frameworks.
  • Familiarity with Docker, cloud deployment, CI/CD practices, and API security.
  • Understanding of AI evaluation techniques, including response quality assessment, prompt testing, and agent workflow validation.
  • Exposure to AI governance concepts, including Responsible AI, guardrails, data privacy, and prompt injection prevention.

Responsibilities

  • Develop AI agents capable of interacting with enterprise systems through APIs, databases, and external tools.
  • Implement function calling and tool integrations that enable agents to perform real-world actions.
  • Create reusable agent components, workflow templates, and AI automation patterns.
  • Develop backend services and APIs using Python, FastAPI, and asynchronous programming.
  • Optimize prompts, agent workflows, and retrieval strategies to improve accuracy, response quality, latency, and cost efficiency.
  • Implement Human-in-the-Loop workflows for approval-based enterprise processes.
  • Build evaluation pipelines to measure agent performance, hallucination rates, and task completion accuracy.
  • Deploy and monitor Generative AI applications using cloud platforms, containerization, and observability tools.
  • Collaborate with AI architects, product managers, and domain teams to convert business processes into agentic AI solutions.

Desired Qualifications

  • Experience building autonomous AI agents or multi-agent workflows.
  • Experience with enterprise automation, IT operations, customer service, or business process automation use cases.

  • Contributions to open-source AI frameworks or Generative AI projects.

About the Company

Photon

Builds custom software and AI for big companies

Photon designs, builds, and runs custom software for large companies, combining an in-house creative agency with its own engineering teams. Its flagship client work includes rebuilding Samsung's US online store as a set of smaller linked services and creating Olive Garden's mobile app, which lets diners join the waitlist from their phones instead of waiting at the door. Clients hire Photon's teams to plan and code their apps, websites, and AI tools and to keep them running afterward, paying for the engineers and designers assigned to each project. Photon is privately held and based in London, with its US arm in Dallas and engineering centers in Chennai and Bengaluru.
