About the Job

Requirements

  • Hands-on experience with large language models such as GPT, Claude, Gemini, Llama, or similar models.
  • Strong prompt engineering skills, including prompt templates, system prompts, few-shot prompting, and response tuning.
  • Experience developing AI-powered applications using large language model APIs, retrieval-augmented generation workflows, enterprise data sources, and backend services.
  • Experience integrating large language model APIs and applications using Python, Java, JavaScript, or similar programming languages.
  • Knowledge of retrieval-augmented generation, embeddings, vector databases, semantic search, and knowledge retrieval workflows.
  • Ability to evaluate and improve AI responses for accuracy, relevance, completeness, tone, and instruction following.
  • Understanding of natural language processing concepts, hallucination mitigation, prompt injection risks, guardrails, and responsible AI practices.
  • Knowledge of healthcare data privacy and secure sensitive-data handling, including HIPAA-aligned protected health information and personally identifiable information practices, data minimization, de-identification, masking, access controls, auditability, and responsible use of healthcare data in AI workflows.

Responsibilities

  • Design, develop, and optimize prompts for large language models to improve accuracy, reliability, and business outcomes.
  • Build and configure agentic AI solutions with planning, reasoning, memory, and multi-step task execution capabilities.
  • Develop and integrate Model Context Protocol tools so AI agents can securely discover and interact with enterprise systems, APIs, and data sources.
  • Design agent architectures, tool-calling frameworks, retrieval mechanisms, and context management strategies.
  • Collaborate with product managers, architects, and engineering teams to translate business requirements into AI-driven solutions.
  • Implement retrieval-augmented generation, knowledge grounding, and context orchestration patterns.
  • Define evaluation frameworks and prompt testing methodologies to measure agent performance, quality, and reliability.
  • Ensure AI solutions adhere to security, compliance, governance, and responsible AI standards.
  • Support deployment, monitoring, troubleshooting, and continuous improvement of AI agents and Model Context Protocol-enabled workflows.
  • Contribute to architecture reviews, technical design documentation, and engineering best practices for AI platforms.

Desired Qualifications

  • Experience with Model Context Protocol servers, cloud platforms, APIs, backend services, and production deployment.
  • Experience integrating AI agents with healthcare, health records, or regulated-industry systems.

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.
