Founding Applied AI Engineer

About Alkali

Alkali is an AI-native price estimation and 3D-modeling platform for construction. We're changing how construction projects are built in the U.S.

Today, steel fabricators estimate the price of multimillion-dollar projects by reviewing paper blueprints with a highlighter. Alkali uses computer vision, VLMs, and agents to produce faster, more accurate estimates.

Each month, steel fabricators across the United States use Alkali to estimate hundreds of projects covering millions of pounds of steel. By volume, more than ~10% of U.S. structural steel flows through our platform.

We are hiring a founding AI engineer to help own Alkali's core AI systems. You will develop and optimize:

• Vision Models: Improve vision models to extract quantities, sizes, quantities, text, etc from engineering drawings.
• Agents: Build agents that navigate large plan sets, use specialized tools, and complete complex estimating and engineering workflows.
• Data and Evaluation Pipelines: Develop the datasets, pipelines, and harnesses to optimize system performance and understand failures.

• Trained and evaluated computer vision models
• Designed data schemas and labeling ontologies
• Built and maintained large-scale data and model pipelines
• Built and evaluated agents with complex tool sets
• The ability to take ownership outside your existing specialty and quickly learn unfamiliar domains, including engineering drawings and construction workflows

You will work with unusually rich visual and geometric data, help shape Alkali's technical direction, and build systems that influence how physical infrastructure gets priced and built. Plus the team is pretty cool!
