Modeling and Analysis Engineer (All Levels)

Unlimited; San Francisco (CA); On-site; USD 120,000 - 200,000; Full time

Job summary

Unlimited in San Francisco is seeking modeling and analysis engineers to advance an AI-driven automated design engine for large-scale capital projects such as utility-scale power and data centers.

The role emphasizes simulation, performance modeling, and optimization tool development. You will own critical bottlenecks and work hands-on in a fast-paced environment, with five days in the SF office.

Qualifications

• Experience building rigid-body dynamics simulators, FEA or CFD 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.
• T-shaped technical excellence: broad understanding across multiple domains and how they interact, implications of trade-offs, etc, while also having deep technical expertise in 1-2 areas.
• Evidence of strong first principles thinking: someone who has challenged and broken through conventional wisdom or "this is how we've always done it" syndrome within their industry to create a step-function improvement.
• 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 builders who can speak to the excruciating minutia and details of their work, and excited to execute instead of manage/organize others work.
• Mission alignment and desire to build a future of abundance

Responsibilities

• Lead engineering development to expand and refine capabilities within our automated design engine product.
• Build and maintain software tools across multiple disciplines for AI-driven design deliverables.
• Collaborate in a fast-paced, high-performance environment with extreme ownership.
• In-person role in San Francisco, CA. We are in the office 5 days per week.

Job description

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 go down in flames.

The role

We're hiring modeling and analysis engineers with backgrounds in simulation, performance modeling, and optimization engine development. You should be inherently systems minded, and capable of building and maintaining software tools across multiple disciplines. In this role, you will lead engineering development to expand and refine capabilities within our automated design engine product, where we leverage AI to automate every step of the engineering process to produce end design deliverables for the construction of large scale capital projects such as utility scale power and data centers.

This role is in-person in San Francisco, CA. We are in the office 5 days per week.

What we're looking for

• Experience building rigid-body dynamics simulators, FEA or CFD 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

• T-shaped technical excellence: broad understanding across multiple domains and how they interact, implications of trade-offs, etc, while also having deep technical expertise in 1-2 areas

• Evidence of strong first principles thinking: someone who has challenged and broken through conventional wisdom or "this is how we've always done it" syndrome within their industry to create a step-function improvement

• 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 builders who can speak to the excruciating minutia and details of their work, and excited to execute instead of manage/organize others work

• Mission alignment and desire to build a future of abundance

Experience:

Actively hiring for every experience level (new-grad, early-career, mid-level, senior, etc)

Bonus:

• You have experience building and/or shipping internal tools or products with AI coding agents
