About the Job

Requirements

  • You have built an application or agent that calls a large language model and can explain what worked and what failed.
  • Your code is tested and maintainable.
  • You use coding agents in your daily work and verify their outputs.
  • You measure the quality of AI outputs using test sets and metrics, and can limit hallucinations, prompt injection, and data leaks.
  • You have put a large-language-model application into production and maintained it, including deployment, monitoring, cost, and latency.
  • You start from the business problem rather than the model, recognize when AI is not the right tool, and can explain this to non-technical people.

Responsibilities

  • Build large-language-model applications and agents, including context design, tool calling, and multi-step workflows.
  • Design how agents use knowledge, including retrieval queries, re-ranking, and citations.
  • Build evaluation datasets and pipelines, including reference answers, automated scoring, and review by business experts.
  • Monitor response quality in production and fix degradations.
  • Select models based on quality, cost, and latency; fine-tune or distill a smaller model when prompting is insufficient.
  • Add safeguards against incorrect answers, data leaks, and prompt injection.
  • Process documents with large language models, including extraction, classification, and summarization.
  • Work with the AI Product Manager and the client's business experts to define good answers and review results together.
  • Participate in peer code reviews and support new hires.

Desired Qualifications

  • Experience with fine-tuning or distilling language models.
  • Education or training in machine learning or statistics, for example in data science.
  • Experience with agent frameworks or protocols such as the Model Context Protocol.
  • Experience with multimodal inputs, including documents, images, or voice.
  • Experience with large-language-model observability tools, including tracing and cost tracking.
