Senior Machine Learning Engineer

Base pay range: $ – $ per year (US). Remote (USA).

We’re transforming how government agencies digitize forms and automate workflows. Our new initiative brings AI directly into this process—using LLMs, vector search, and structured PDF parsing—to accelerate public service delivery. This isn’t an R&D sandbox; it’s about delivering intelligent automation that impacts real users now.

Responsibilities
  • Build and tune vector‑based retrieval pipelines using OpenAI embeddings and Azure AI Search.
  • Design prompt strategies and agents to translate parsed PDF data into form component schemas.
  • Fine‑tune LLMs for structured output generation with low‑latency performance in mind.
  • Lead the development of an RLHF loop that incorporates builder UI feedback and audit data.
  • Help architect systems that blend traditional APIs and probabilistic inference reliably.
  • Work alongside full‑stack and platform engineers to ship solutions to production.
  • Stay plugged into the latest model capabilities and make smart adoption decisions.
Qualifications
  • 5+ years in applied machine learning, including experience with retrieval, embeddings, and prompt engineering.
  • Strong Python skills and familiarity with production‑grade ML pipelines.
  • Experience designing and tuning RAG workflows with hybrid search.
  • Familiarity with RLHF and fine‑tuning on structured JSON output.
  • Solid grasp of system‑level thinking—how to bring ML into product environments cleanly.
Tech Stack
  • Azure AI Studio, Azure OpenAI, GPT‑4o
  • Python (agents, functions, orchestration); .NET 8 (integration layers)
  • Azure AI Search, Cosmos

    DB, MSSQL
  • Kubernetes (AKS), Azure Blob, Octopus for CI/CD
  • Extend.ai for structured PDF parsing
Benefits
  • 100% remote (US)
  • Help shape AI transformation of public‑sector services
  • Lead initiatives that ship real impact, not just prototypes
  • Greenfield development on a proven, profitable platform
  • Comprehensive Health, Vision and Dental coverage for individuals and families
Success in 6 months
  • Shipped a working vector search + RAG pipeline integrated into our form builder.
  • Scoped and kick‑off our first LLM fine‑tuning cycle.
  • Collected human feedback to improve model accuracy.
  • Defined the roadmap for AI integrations across the platform.
