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 some of Silicon Valley's top investors, we’re building a small, engineering-led team to scale what’s working and to take on one of the most important challenges of the coming decades.

About the Role:

We’re looking for a Product Engineer to help build the software that connects AI, engineering, and design. You’ll translate complex physical systems and workflows into intuitive digital tools that engineers actually want to use. This role blends product design, full-stack development, and systems thinking - you’ll move fluidly between prototypes and production code, bringing ideas to life fast and iterating with real users.

You’ll work closely with our software, mechanical, electrical, and civil engineering teams to design and build our AI-native engineering platform. The right person will have a designer’s instinct for clarity and an engineer’s drive to ship. It’s more important that they have great product taste and the ability to move quickly than the most elegant and scalable backend code ever written.

What You’ll Do:

• Design and build features end-to-end across Unlimited’s web platform that help accelerate the building of large physical infrastructure.

• Embed with customers and automate their manual workflows with AI, using core primitives in the Unlimited platform

• Rapidly iterating with customers and our internal team to go from concept to production.

• Thoughtfully design underlying data models and interactions for real engineering and project development workflows.

You Have:

• Experience as a product designer, product engineer, or full stack engineer building modern software applications.

• Fluency using AI tools to accelerate product design and development.

• A track record showing end-to-end ownership from initial design and prototyping to implementation and iteration.

• Ability to build across the stack.

• Interest in technical or systems-heavy products, especially tools used by engineers, builders, or operators.

• Excellent communication skills with the ability to collaborate across disciplines, translating between engineering domains to solve complex, cross-functional problems.

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

• Ability to travel to projects and embed with customers as needed.
