The Role
Own end-to-end process design for large-scale capital projects, including heat and material balances, PFDs, P&IDs, emissions control, and equipment sizing. Translate expert engineering judgment into capabilities for an AI-powered automated design engine. Work hands-on across gas power, industrial, chemical, or polymer plants, applying first-principles thinking and collaborating across engineering disciplines. Experience with utility-scale natural gas power, simulation tools, or AI coding agents is advantageous.

Mission:

We are automating construction end to end to usher in a new era of abundance and beauty in the physical world in the coming decades. Over the past fifty years, the West’s ability to design and build large scale infrastructure has atrophied, and the entire industry has become less productive. With decaying infrastructure, power shortages, and an aging workforce, the only way through is to hyper-scale development with technology at a rate never before seen.

 

Our team believes that this is the most important work of our lives, and there’s no more significant place to spend our time than on solving these problems. We believe in the sacrifices that we must make to achieve our mission and build a world of abundance. We believe the future can be amazing, but only if we work gut-wrenchingly hard to make it so. Our work is bigger than all of us, and our obsession with manifesting is what drives us. Roughly 50% of our team are former founders, and we strive for technical excellence, but quell our egos to ensure that the best ideas always win.

 

We acknowledge the long and arduous path ahead to achieve our ambitions; that many of the most difficult challenges have yet to even be revealed to us; that the chance of failure is not only possible, but likely. Most of all, we believe that there is no other option: we will either revolutionize how humanity builds or die trying.

 

The role:

We're hiring a Senior Process Engineer to bring deep, practicing process engineering expertise into our product. You'll pair years of hands-on plant design experience (heat and material balances, PFDs and P&IDs, emissions control, equipment sizing, etc) with product development, turning how an excellent process engineer thinks, checks, and makes judgment calls into capabilities within our automated design engine product, where we leverage AI to automate every step of the engineering design process to produce end construction design deliverables for large scale capital projects such as natural gas power generation and beyond.

 

This role is in-person in San Francisco, CA.

 

What we're looking for:

  • Owned the process design of gas power, industrial plants, chemical production, polymer synthesis, or similar, end to end

  • T-shaped technical excellence: broad understanding of how process connects to adjacent disciplines and the implications of trade-offs across them, while also having deep expertise in 1-2 areas

  • Evidence of strong first principles thinking: someone who has challenged "this is how we've always done it" syndrome

  • Excitement to work in a fast-paced, high-performance environment, and embrace extreme ownership

  • The ability to prioritize impact by ruthlessly finding the bottlenecks and solving the most important problems

  • Hands-on engineers who can speak to the excruciating minutia and details of their work (the calc, the edge case, the reviewer comment that changed the design), and are excited to execute instead of manage/organize others' work

  • Mission alignment and desire to build a future of abundance

Experience: Senior. Significant hands-on process design experience at an engineering firm or owner; PE preferred.


Bonus:

  • Experience with utility scale natural gas power generation plant design

  • Experience building your own simulation, calculation, or analysis software tools or other applications. A large part of this role is turning your engineering knowledge into scalable software; even if you’ve barely written software before, you’ll leverage recent advancements in AI coding agents to assist you in building these tools

  • Experience with AI coding agent tools (Codex, Claude Code, etc) for work or personal uses

Skills Required

  • End-to-end ownership of process design for gas power, industrial plants, chemical production, polymer synthesis, or similar facilities
  • Hands-on plant design experience involving heat and material balances, PFDs, P&IDs, emissions control, and equipment sizing
  • Broad understanding of process engineering connections to adjacent disciplines and cross-disciplinary trade-offs
  • Deep expertise in one or two process engineering areas
  • Strong first-principles thinking and ability to challenge established practices
  • Ability to prioritize high-impact bottlenecks and solve the most important problems
  • Hands-on execution skills and detailed knowledge of engineering calculations, edge cases, and design reviews
  • Significant senior-level process design experience at an engineering firm or owner
  • Professional Engineer (PE) license
  • Experience designing utility-scale natural gas power generation plants
  • Experience building simulation, calculation, analysis software, or other applications
  • Experience using AI coding agent tools such as Codex or Claude Code

What We Do

Unlimited is an AI-native engineering and construction company. We're here to fix the 50-year decline in our ability to build critical infrastructure: power plants, factories, data centers, and the like. We envision a future of unprecedented abundance - where energy is limitless, the built world assembles itself, and our physical environment constantly inspires us to reach for more. This will not be easy. We’re on a multi-decade long journey to fully automate construction and in doing so, accelerate the pace of human progress. Unlimited is working with industry leading companies to design and build large-scale industrial projects in mining, energy, advanced manufacturing, and data centers. We are currently delivering projects in the United States, and will expand internationally in the future. If you need to design and build projects across mining, energy, process technology, advanced manufacturing, or data centers, and want to redefine what's possible, please get in touch. If you're a builder and you deeply resonate with the mission, come help us make it a reality.
