Physical AI Infrastructure Architect

• We are building the intelligence layer that allows physical infrastructure to understand itself, predict its future state, and autonomously optimize its operation.
• Our mission is to solve one of the most important bottlenecks facing the AI economy: power, cooling, and operational efficiency inside data centers and other mission-critical environments.
• We are looking for an architect who wants to lead this effort.
• You will work directly with the founding team to architect and build the fi rst commercial version of client’s Physical AI platform.
• You will make foundational decisions that influence the next decade of the company.
• You will build software that directly interfaces with physical infrastructure operating in real-world environments where reliability matters.
• You will help transform years of research, modeling, controls engineering, and AI development into a production system capable of scaling across mission-critical facilities.
• If you enjoy solving hard technical problems at the intersection of software, physics, controls, and AI, this role was designed for you.

Why This Role — and Why Now

• This is not a software leadership role at a mature technology company where the architecture is already defined, the roadmap is already written, and success is measured by incremental improvements to an existing platform.
• This is an opportunity to become the founding architect of a new category of technology: Physical AI for critical infrastructure.
• Client is at a unique inflection point. Our underlying technology is built upon years of research, physics-based modeling, optimization, and real-world validation. We are now transitioning from proven technology to commercial deployment, and we are looking for the architect who will help transform that foundation into a scalable software platform capable of redefi ning how data centers and other mission-critical environments are operated.
• As a Founding Lead Software Architect, you will be the technical leader responsible for defining the software architecture, technology strategy, and foundational engineering principles of Client''''''''''''''''s Physical AI platform. You will work directly with the founders to transform years of research in digital twins, optimization, controls, and artifi cial intelligence into a production platform capable of operating within mission-critical infrastructure environments.

The person who joins now will:

• Define and guide the architectural vision for client''''''''''''''''s Physical AI platform.
• Architect and develop software across the full technology stack including edge systems, backend services, APIs, databases, and user-facing applications.
• Design scalable telemetry, time-series, and real-time data processing systems.
• Develop integrations with building automation systems, HVAC equipment, sensors, and industrial infrastructure.
• Transform digital twins, optimization engines, and AI models into production-ready software.
• Establish engineering standards, observability, testing strategies, deployment processes, and architectural best practices.
• Collaborate with founders, researchers, customers, and industry partners to align technology with business objectives.
• Participate in technical hiring and help shape client''''''''''''''''s engineering culture.

We are looking for a builder first and a leader second—someone who enjoys architecting systems, writing code, solving difficult technical problems, and turning ambitious ideas into working products.

The ideal candidate is energized by ownership, thrives in ambiguity, moves quickly, and is motivated by the opportunity to build something meaningful from the ground up. The impact of your work will be visible not only in the software you create, but in the foundation of the company itself.

For the right person, this is a rare opportunity to become a defining technical force in a company at the earliest stages of growth and help create technology that will infl uence the next generation of intelligent infrastructure.

Core responsibilities

Platform Architecture and Core Engineering: FTE: ~25% | Daily

Physical AI & Model Operationalization | ~10% | Weekly
Partner closely with researchers and domain experts to transform digital twins, optimization algorithms, and AI models into production-ready software. Ensure that advanced modeling and decision-making capabilities are implemented in a manner that is scalable, maintainable, explainable, and operationally reliable.

Engineering Excellence and Operational Standards: FTE: ~10% | Weekly
Establish and maintain best engineering practices across the platform, including reliability patterns, monitoring and observability, testing strategy, deployment processes, and documentation standards. Build the operational foundation that keeps the platform stable, auditable, and maintainable as both the codebase and the engineering team grow.

Technical Leadership & Engineering Excellence | ~5% | As Needed
Help establish the technical culture, engineering practices, and architectural standards that will guide future growth. Participate in technical hiring, mentor engineers when appropriate, and contribute to creating a high-performance engineering organization focused on speed, quality, ownership, and execution.
