Description

  • Scale embeddings, vector storage, and retrieval across a large evidence base with tracked provenance
  • Connect language models to source records so generated text remains citation-grounded
  • Evaluate citation errors and measure grounding quality
  • Create prompts and structured output schemas
  • Manage model packaging, version control, serving, and rollback
  • Track retrieval and generation quality, recommendation and version attribution, overrides, abstentions, grounding failures, latency, throughput, and measurement events
  • Apply bounded model assistance to challenging narrative extraction while linking every result to its source passage
  • Include recorded rule context in each model-assisted operation, with exact rule versions and ordered context
  • Operate a modular in-boundary serving path, whether self-hosted or managed, alongside the primary managed inference service
  • Ship generated explanations, scalable retrieval, dependable rollback, and comprehensive measurement telemetry

Requirements

  • Bring at least five years of experience, including a production or near-production retrieval-augmented generation system you built yourself
  • Be prepared to explain your retrieval architecture, vector store selection, grounding tests, real-world citation failures, and rollback approach in detail
  • Demonstrate strong Python skills and hands-on experience with embeddings and large-scale vector retrieval
  • Clearly distinguish what you have shipped—prototype, proposal, or deployed code—because delivery experience matters more here than a résumé title
  • Hold US citizenship
  • Have an active US Secret clearance at the start date
  • Experience deploying models in restricted or air-gapped environments is preferred
  • Experience operating self-hosted or open-weight models is preferred
  • Experience with fine-tuning, adapters, or custom embeddings is preferred
  • Experience with federal DevSecOps, RMF, ATO, or Department of War cloud environments is preferred
  • An active Top Secret clearance is preferred

Benefits

  • Work fully remotely in a results-oriented environment
  • Receive a competitive salary, bonus, and equity package
  • Get fully employer-paid medical, dental, and vision coverage for you and your family
  • Use unlimited paid time off with manager approval
  • Manage your schedule in a flexible work environment
  • Take 14 weeks of fully paid parental leave
