About the role
- Acquisition is slow, paper-heavy, and consequential; we're using agentic AI to make it faster and more defensible without lowering the bar on rigor.
- Your work will ship into production environments where the decisions really matter.
- This is a hands-on individual contributor role.
Responsibilities
- You will design, develop, and deploy sophisticated multi-step AI agents capable of reasoning over complex procurement documents, managing long-horizon workflows, and delivering precise, defensible outputs in high-stakes environments.
- Develop tool-using, reasoning, and planning capabilities that enable agents to decompose complex acquisition problems into executable subtasks.
- Build robust human-in-the-loop and approval gates for high-stakes decision points within automated workflows.
- Graph RAG & Document Intelligence Design and optimize Retrieval-Augmented Generation (RAG) pipelines to ground agent outputs in authoritative procurement data, regulations (FAR/DFARS), past performance records, and institutional knowledge.
- Develop document parsing and structuring pipelines for RFPs, SOWs, PWS, solicitations, and other complex government acquisition artifacts.
- Implement prompt engineering best practices, including structured outputs, chain-of-thought reasoning, and few-shot prompting optimized for acquisition workflows.
Requirements
- What You'll Bring Required 8+ years of software engineering experience, with at least 1 year focused on LLM applications, AI agents, or applied ML systems in production.
Skills
- Deep understanding of RAG architectures, vector databases (Pinecone, Weaviate, pgvector or similar), and embedding models.
