Build the backend of a custom AI platform from scratch for a US general contractor modernizing its federal bidding process. You’ll work directly with an architect and AI expert, influence foundational technical decisions, and gain hands-on experience with document processing, LLM orchestration, RAG pipelines, and multi-tenant data.
The platform will turn solicitations from SAM.gov into structured insights, evaluate opportunities against company certifications and past performance, and support proposal drafting and submission. Your work will power a Go/No-Go engine that helps teams decide which bids to pursue.

A new team member will be in charge of

Building the backend foundation: project setup, authentication, role-based permissions, and an immutable audit log.
Implementing solicitation intake from SAM.gov, PDF/DOC/HTML parsing, and OCR with per-field confidence scores.
Building LLM orchestration for structured extraction, retries, fallbacks, citation tracking, and cost control.
Developing bid scoring against certifications and past performance, with Word, PDF, and Excel exports for Go/No-Go reviews.
Preparing the platform for production: OWASP baseline security, secrets management, CI/CD in the client’s AWS environment, and runbooks and documentation for handover.
