Founding AI/ML Engineer

Role Description

We are hiring a Founding AI/ML Engineer to architect and ship production-grade AI systems transforming one of the world’s largest and least automated industries — construction. This is a product-first AI engineering role focused on multimodal intelligence, document understanding, and agentic workflow automation. You will work directly with the Chief AI Officer and founders to move from low-automation to high-automation mode, where AI agents perform core operational work with light human oversight.

Qualifications

• 6+ years of engineering experience
• Experience at an early-stage, high-growth startup
• Shipped production-grade AI systems to real customers
• Hands-on LLM and/or computer vision experience
• Retrieval systems experience (embeddings, chunking, grounding)
• Agentic workflow experience (tools, APIs, state management, retries, guardrails)
• Strong backend fundamentals:
• APIs
• Async jobs / queues
• Databases
• Cloud deployment
• Monitoring
• Full end-to-end ownership mindset

Requirements

• Build and ship production-grade AI systems used daily by real customers
• Design multimodal pipelines for drawings, specs, and construction documents
• Build agentic workflows automating preconstruction tasks:
• Document intake
• Extraction
• Takeoff support
• Bid preparation
• QA workflows
• Build and improve:
• Retrieval systems (embeddings, reranking, chunking)
• Evaluation systems
• Orchestration layers
• Optimize model quality, latency, reliability, and cost efficiency
• Prototype and iterate quickly on customer-facing AI features
• Own systems end-to-end (experiment → deploy → monitor → improve)
• Help shape engineering culture and long-term technical direction

Benefits

• Meaningful early-employee ESOP grant
• Employer-funded health insurance (Patch model)
• Team / meal stipend
• Growth path to technical leadership (optional management track)
