AI Research Engineer

Job DescriptionJob DescriptionAbout Muro AIMuro AI is transforming how the $2T construction industry plans and builds. Founded by Cornell alumni, ex-founders, and former McKinsey operators, we're building AI agents that automate the most complex, manual, and costly phase of construction: preconstruction.We move fast, build with conviction, and obsess over delivering real impact to the people who build our world. If you want to define how AI understands and reasons over architectural and design documents at scale, this is where it starts.Why This Role ExistsCrack the hardest problems in construction tech: enabling AI to deeply understand architectural documents—and then act on them. We're building systems that don't just read plans, but reason across them and execute complex workflows using specialized industry tools.Shape a category: No one owns "pre-con AI" yet. You'll build the core research—from document understanding to agentic execution—that sets the foundation.Move the industry: Your work will help contractors win multimillion-dollar bids, eliminate scope gaps, and unlock massive productivity gains.Who You AreA research-minded builder with 4–6+ years of deep technical ML experience.You're comfortable in the messy 0→1 phase: half-baked specs, ambiguous problem statements, and solving foundational technical challenges that will define the next decade of construction AI energize you.You're curious, rigorous, and want to own hard problems end-to-end—from research to production. You communicate complex work clearly to engineers, product, and leadership; you're the go-to scientist the team turns to when they need to understand what's possible.Your Mission1. Build the document understanding layer that powers everything downstreamCreate the foundational multimodal system that all downstream agents depend on. Research and build models that understand complex construction-specific documents formats - using custom fine tuned multimodal models and RAG architectures. Architect pipelines for OCR, image segmentation, layout analysis, entity resolution,... Build rigorous evals and benchmarks from real-world documents.2. Push agentic AI into productionContext engineer construction the agent harnesses for multi-step construction workflows. As well as, architect and expose novel tools. Own the full path from prototype to deployment alongside the AI engineering team.3. Make AI reliable for million-dollar decisionsBuild labeled datasets with construction SMEs. Develop hallucination-detection, confidence calibration, and evaluation frameworks tailored to the most complex AEC tasks.Who Should ApplyWe want research-driven builders who love pairing deep model work with real customer understanding.You might be:A Research Engineer/Scientist looking to see your work deployed, not just publishedAn ML Engineer or Applied Scientist who wants to push the frontier on multimodal and agentic systemsA Software Engineer who has transitioned into deep AI/ML research and wants to own problems end-to-end. And wants to productionize their new skill set.A founding-team caliber engineer eager to tackle the hardest technical challenges in AEC techYou'll Stand Out If You HavePrior 0→1 or founding-team experience at a startupExperience working directly with users or in forward-deployed environmentsBuilt a multimodal model or document-understanding pipeline used in productionHands-on experience with RLHF, DPO, SFT, or parameter-efficient fine-tuning methodsAdvanced OCR/CV experience (layout-aware models, document transformers, segmentation)Designed or scaled RAG systems for complex, multi-document retrievalExperience with agentic LLM systems, tool use, or multi-step reasoning harnessesBackground in architectural/engineering drawings (AEC experience is a plus, not required)Location: In-person in San Francisco.
