Boon AI is building the agentic operating system for construction preconstruction — the layer that reads blueprints, specs, and bid documents, and does the estimator's work with them. Our platform spans a Rails product monolith, Python computer-vision services (DINOv3/SAM-class vision models reading drawings), an LLM agent runtime orchestrating multi-step construction workflows, and model/eval infrastructure that keeps accuracy honest. We're live with GCs and subs across the country, shipping daily, and scaling from thousands to hundreds of thousands of drawings per month.

As a Senior Software Engineer, you'll own meaningful features and services across this platform, solve challenging technical problems, and help build a system that scales with our customers.

Own features and services end to end across the Rails product app, Python ML/CV services, agent SDK layer, and data platform — balancing customer requirements, maintainability, and shipping speed

Improve the scalability, reliability, and cost efficiency of our computer vision/LLM/VLM inference pipelines as we scale blueprint throughput

Build and improve our model infrastructure, including vision model integration, LLM orchestration, agent workflows, MLflow registry, and eval harnesses

Contribute to architectural decisions, write clear design docs, and raise the engineering bar through thoughtful code review

Share knowledge and mentor teammates as the engineering team grows

Partner with product and engineering teammates to scope work, evaluate build-vs.-buy decisions, and turn customer needs into reliable software

Write and ship production code regularly, troubleshoot issues, and participate in incident response

You’re a Great Fit If:

You've shipped production systems that handle messy real-world input — documents, PDFs, images, OCR, or user-generated data
