About Our Client

Our client, a well-funded Series A startup founded in 2022, is revolutionizing development in the U.S. by streamlining collaboration between developers, builders, and local regulatory authorities. Their software powers a Private Plan Review platform that’s already used by some of the nation’s largest retailers, developers, and production home builders.

Backed by nearly $40M in funding from top-tier venture firms (including a recent $28.5M Series A), they are at the forefront of transforming the construction permitting and plan review process—reshaping a multi-hundred-billion-dollar industry.

What You’ll Do

Leverage rich proprietary datasets, including:
Building codes across every U.S. jurisdiction
Expert-generated comments on building plans
Validation and input from in-house architects and code specialists
Own decision-making on MLOps tech stack and collaborate closely with data engineering.
Optimize scalable data processing pipelines and maintain ML infrastructure.
Design, develop, deploy, and monitor innovative ML solutions that drive efficiency for customers.
Architect and maintain workflows that automate the path from feature store to inference.
Build greenfield pipelines for pre-training and fine-tuning domain-specific LLM/CV models.
Shape RLHF and retrieval pipelines to encode compliance knowledge.
Experiment with and evaluate novel approaches for proprietary LLMs and CV models.

About You
