Title:
AI Solutions Architect
Location : Reston, VA
Position Summary
Johnson Technology Systems Inc. (JTSi) is building the next generation of AI-native infrastructure for U.S. federal contracting. We are looking for an AI Solutions Architect to own the design, development, and delivery of intelligent platforms across our proposal automation, talent acquisition, and CRM integration workstreams.
This role sits at the center of JTSi's AI Initiatives R&D function. You will architect multi-LLM pipelines, design retrieval-augmented generation (RAG) systems over federal contracting corpora, and integrate AI capabilities directly into OfficeGaps—JTSi's proprietary SaaS CRM. You are both a technical builder and a systems thinker who can translate defense and civilian agency workflows into production-ready AI tooling.
KEY PROJECTS YOU WILL OWN
JTSi Vertex — Federal Proposal Management Platform
Vertex is JTSi's internal AI platform that automates the federal proposal lifecycle end-to-end—from opportunity ingestion across SAM.gov and GovWin through compliance-checked draft generation. Built on multi-LLM orchestration (Claude and GPT), RAG-based retrieval over past proposals and CPARS records, and a FastAPI integration layer connected to OfficeGaps.

• Extend and scale the document ingestion, parsing, and vector retrieval pipeline (Chroma, Pinecone)
• Orchestrate multi-model LLM workflows across scope analysis, requirement extraction, FAR compliance review, and past-performance matching
• Own the FastAPI integration exposing Vertex capabilities to OfficeGaps and downstream JTSi workflows
• Drive Vertex from pilot phase into full production across JTSi's proposal and business development teams

Formant AI — Document & Resume Intelligence Platform
Formant is JTSi's AI-powered document and resume formatting engine. The platform automates candidate document processing, normalizes resume inputs to enterprise templates, and serves as the intelligent document layer feeding both AI Recruiter and broader talent acquisition workflows.

• Architect the document processing and normalization pipeline for federal staffing and proposal documents
• Design and extend LLM-driven formatting logic to support multi-format output (federal templates, ATS-optimized, executive-ready)
• Build and maintain the Formant workspace and user-facing interface—standalone homepage and functional processing environment
• Integrate Formant's document intelligence layer with OfficeGaps Contacts and Procurement tabs via the Agentic AI Initiative

• Orchestrate multi-LLM workflows (Claude, GPT) across document analysis, compliance review, and content generation tasks
• Develop and maintain FastAPI services integrating AI platform capabilities into OfficeGaps and other enterprise systems
• Lead the Agentic AI Initiative—identify, scope, and deliver AI enhancements to the Contacts and Procurement tabs within OfficeGaps
• Maintain vector stores (Chroma, Pinecone) and embedding pipelines ensuring retrieval quality and latency targets are met
• Collaborate with proposal, recruiting, and business development teams to translate operational workflows into AI product specifications
