Role

Who you are

5+ years of experience in machine learning engineering, with production ML experience
Deep expertise in NLP and LLMs (OpenAI GPT, Claude, Hugging Face models)
Experience building retrieval and vector search systems (e.g., FAISS, Elasticsearch, Pinecone, Weaviate)
Proficiency in Python and ML frameworks like PyTorch or TensorFlow
Strong track record of deploying and scaling ML systems with measurable business impact
Experience with cloud ML infrastructure (AWS, GCP, or Azure)

You will own the end-to-end ML lifecycle, from model research and data engineering to production deployment and continuous evaluation
Design, implement, and optimize LLM-powered models for document processing, data extraction, and permit workflow automation
Develop retrieval-augmented generation (RAG) pipelines and search/retrieval systems for jurisdictional and regulatory data
Rapidly prototype, fine-tune, and evaluate pre-trained models for real-world NLP tasks like classification, entity recognition, and summarization
Build scalable ML infrastructure and backend services, integrating models into production systems that power AI agents
Work with large structured and unstructured datasets to improve indexing, retrieval, and contextual accuracy
Own the full ML lifecycle: experimentation, deployment, monitoring, evaluation, and iteration
Balance ML, retrieval, and rule-based approaches to ship reliable, maintainable, and high-impact AI features
Collaborate with engineering, product, and domain experts to shape ML-powered solutions for complex pre-construction challenges

Our take

Aiming to release value in the construction market, PermitFlow is an AI-powered construction permit application and management platform. It exists to simplify the pre-construction process for builders and owners, enabling them to move forward with projects more easily.

The company offers a standardized permit application workflow through which users can easily prepare and submit permit applications, receive approvals, and respond to municipal comments on one single platform. This saves time, reduces errors and shortens municipal review cycles, ultimately speeding up the time taken to permit.

Through the deployment of advanced technologies, PermitFlow has kept up with the needs of a changing market, benefitting builders and stakeholders across the nation. As AI has advanced, so too have the company's algorithms, bringing in new functionalities such as voice AI agents that can schedule an inspection as soon as a project is permitted.
