Product Engineer (Civil)

Department: Engineering

Location: San Francisco

Employment Type: FullTime

About Unlimited:

Unlimited is an AI-native engineering and construction company reimagining how large-scale physical infrastructure gets built – from factories to power plants to entire industrial systems. We’re already delivering real projects with customers across multiple industries, using our AI-first engineering platform to design an order of magnitude faster than industry norms.

Backed by a $12M seed round from Andreessen Horowitz, CIV, Bessemer, and other leading investors, we’re building a small, engineering-led team to scale what’s already working and to take on one of the most important challenges of the coming decades.

About the Role:
We’re looking for civil engineers who take ownership from early site planning through construction, and who want to help build the product that will automate those workflows in the future. You’ll shape the physical backbone of our projects, from site layouts and grading to drainage, foundations, and underground utilities across factories, process plants, data centers, power projects, and mining operations.

This isn’t a traditional role. You’ll work inside our AI-native engineering framework, where the tools learn from your decisions and encode your judgment into reusable models. The platform you help build will drive how Unlimited designs and executes every future project. The right person will see this as more than a faster way to engineer - it’s a chance to embed their knowledge into a system that scales their impact across every future project Unlimited builds.

What You’ll Do:

• Lead civil design for industrial facilities, including site layout, grading, drainage, foundations, and underground utilities.

• Design and analyze concrete foundations, slabs, and structural supports for heavy equipment and process systems.

• Coordinate civil and structural designs with mechanical and electrical teams, ensuring proper interface for equipment, utilities, and routing.

• Develop and review design packages including earthwork plans, utility routing, and concrete details for constructability.

• Use and improve Unlimited’s AI-powered engineering tools to automate site design, grading, and foundation workflows.

• Support field execution and construction planning, resolving issues related to layout, drainage, or foundation performance.

• Participate in projects from concept through commissioning, validating automated designs against real-world site conditions.

• Identify opportunities for standardization and modularization of civil design elements across projects.

You Have:

• A strong foundation in civil or structural engineering, with experience designing and executing site and foundation work for factories, process plants, or other large industrial facilities.

• Hands-on experience with site grading, drainage, or utility coordination for industrial or heavy infrastructure projects.

• Familiarity with foundation design for heavy equipment and structural integration with mechanical and electrical scopes.

• Experience with civil design and modeling tools (Civil 3D, Revit, STAAD, or similar) and an interest in how these workflows can be automated or reimagined.

• Understanding of construction sequencing and field coordination, including concrete placement, layout, and surveying.

• Curiosity about AI and how intelligent systems can extend engineering capability.

• Strong communication skills and the ability to collaborate across disciplines to solve cross-functional challenges.

• Comfort working under tight deadlines and ambiguity in a fast-paced, high-output environment.

• Ability to travel to project sites and customer locations as needed.
