This AI startup is pioneering intelligent automation across the construction lifecycle-from blueprint analysis to jobsite monitoring leveraging computer vision to bring previously untapped data to life. With $30M in funding and a growing team of 50+ employees, including 20+ engineers, they’re launching a suite of AI agents that tackle challenges in:
- Image understanding
- Document intelligence
- Visual Q&A
- Multi-modal reasoning
They’re reimagining how visual and spatial data is used on-site and across operations, using AI to drive accuracy, speed, and cost efficiency.
THE ROLE
As a Senior Computer Vision Engineer, you’ll take ownership of designing, building, and deploying CV models that process and interpret a wide range of visual data.
You’ll be instrumental in shaping the company’s AI roadmap and embedding sophisticated visual understanding into production-ready tools used by field and office teams alike.
You will:
- Develop, train, and deploy CV models for object detection, image classification, segmentation, and more
- Design scalable ML pipelines to support model training, evaluation, and integration
- Work with proprietary datasets and define efficient labeling strategies to improve model performance
- Collaborate cross-functionally with ML, backend, and product teams to build user-centric solutions
- Apply state-of-the-art CV research, including visual transformers and multi-modal learning techniques, to production use cases
- Stay up to date with innovations in LLMs, RAG pipelines, and vision-language models, contributing where appropriate
YOUR SKILLS & EXPERIENCE
We’re looking for a CV engineer who brings both depth in technical knowledge and a builder’s mindset.
Must-haves:
- MS or PhD in Computer Science, Computer Vision, Robotics, or a related field
- 5+ years of experience building and deploying computer vision systems in production
- Proficiency in Python and frameworks such as PyTorch, TensorFlow, and OpenCV
- Deep understanding of image processing, feature extraction, and model evaluation techniques
- Hands-on experience with transformer-based CV models (e.g., ViT, DINO, SAM) and/or multi-modal architectures
Bonus skills:
- Exposure to LLM-based systems or Retrieval-Augmented Generation (RAG) pipelines
- Experience working with blueprints, schematics, or construction-specific datasets
BENEFITS & CULTURE
- Highly competitive salary ($200K-$250K) + meaningful equity package
- Fully remote flexibility across the US, with optional hybrid setups in NYC
- Comprehensive health benefits, medical, dental, vision (100% covered plan available)
- Unlimited PTO to support work-life balance
- Annual learning & development budget to fuel your growth
- Frequent team offsites, meetups, and daily in-office lunches (NYC)
- Work with an exceptionally talented and collaborative team solving challenging technical problems
