About the Job

Requirements

  • Experience building rigid-body dynamics simulators, finite element analysis or computational fluid dynamics solvers, or other physics or engineering modeling tools for internal use or as external products.
  • Experience writing trade-study and optimization tools to study design spaces for complex system analysis.
  • Broad understanding across multiple technical domains and how they interact, including the implications of trade-offs, with deep technical expertise in one or two areas.
  • Evidence of strong first-principles thinking and creating substantial improvements beyond conventional approaches.
  • Ability to work in a fast-paced, high-performance environment and embrace extreme ownership.
  • Ability to prioritize impact by identifying bottlenecks and solving the most important problems.
  • Hands-on building experience with detailed knowledge of the work and willingness to execute rather than manage or organize others’ work.
  • Alignment with the mission and desire to build a future of abundance.

Responsibilities

  • Lead engineering development to expand and refine capabilities within the automated design engine product.
  • Build and maintain software tools across multiple disciplines.
  • Develop modeling, simulation, performance modeling, and optimization capabilities for automated engineering design.
  • Contribute to producing end design deliverables for large-scale capital projects such as utility-scale power and data centers.

Desired Qualifications

  • Experience building and/or shipping internal tools or products with artificial intelligence coding agents.

AI-native construction design and delivery platform

Unlimited designs and builds critical infrastructure (power plants, factories, data centers) using an AI-native platform that combines engineering, cost, and project data in one system to accelerate pre-construction. Engineers explore more design options and compress design cycles from months to days, with updates processed continuously instead of through design freezes and change orders. The platform supports incentive-aligned, milestone-based outcomes rather than billable hours, aiming to automate construction end to end for owners and developers of large industrial projects. Its goal is to deliver projects on time, on budget, and to specification by using automation and data-driven, integrated workflows.
