mbue | Hybrid (Austin, TX) | Full-time | Machine Learning Engineer (CV + LLM) | https://www.mbue.ai

We’re automating architectural review in construction. mbue is an AI-first startup helping commercial contractors catch costly mistakes in architectural drawings before they’re built. Our Smart Overlays go beyond Bluebeam by detecting subtle, scope-impacting changes using computer vision and LLMs. We’re backed by top investors and growing fast. Now we’re hiring ML Engineers to build, ship, and own production models end-to-end.

Tech: Python, PyTorch, OpenCV, Transformers, ViTs, CNNs, LLMs

What you'll do:

* Build & deploy deep learning models to analyze and compare architectural drawings

* Tackle noisy, multimodal input: plan sets + spec text

* Own models from prototype to production

* Collaborate to deliver user-facing features

* Move fast and take full ownership

What we're looking for:

* 3+ years of hands-on ML experience (CV, DL, and/or LLMs)

* Strong Python + ML fundamentals

* Experience shipping models in production

* Startup experience or zero-to-one mentality

* Based in Austin or open to relocating (hybrid role)

This isn’t an R&D role—it’s for builders who want their models in the hands of real users. If you're excited to reshape how the built world gets made, we’d love to meet you.

Some even tell us that their partners notice they're much more relaxed after starting to use our product, and we couldn't be happier :)

We're expanding our Stockholm team with exceptional engineers! We use Python (backend), TypeScript/React (frontend) and C# (Windows app) and our infrastructure runs on Kubernetes in Azure. We're scaling rapidly in terms of # of users and are especially keen to talk to senior backend engineers who have helped startups scale from thousands to millions of users.
