About the Role

This is a career-defining opportunity to play a crucial role in a hyper-scale AI company that is transforming the future of autonomous systems, energy, and the built environment.

As the Computational Physics Software Engineer, you will play a meaningful role in our Digital Twins team developing the differentiable physics-based equipment inferencer environment within an AI-driven control engine.

What you’ll do

• Build infrastructure: Develop and maintain infrastructure for a differentiable multi-physics simulation engine.
• Design interfaces: Develop an interface with the object model through Object Relational Mapping.
• Control path support: Provide an infrastructure to support PassiveLogic’s control path predictor and front-end simulation environments.
• Develop autonomous systems: Develop robust autonomous software that must run with no human supervision for decades.
• Ensure robust systems: Use thoughtful architecture design, documentation, unit testing, integration testing, profiling, and collaboration with the Formal Methods team to ensure this robustness.
• Collaborate: Collaborate with the Digital Twins team for physics optimization and collaborate with the Compiler team for accelerator approaches.

What you’ll bring

If your experience does not meet all our posted requirements below, we’d still love to hear from you. We are looking for practitioners who are passionate about understanding people, committed to lifelong learning, and driven by the love of what they do. If that’s you, please apply!

You must have

• Proven experience: Strong proficiency in systems programming languages such as Swift, Rust, C++, or Java, as well as appreciable software engineering skills in working with large codebases with non-trivial architecture, beyond just coding small (1000’s of lines) programs and scripts
• Exceptional communication skills: Extraordinary teammate with excellent interpersonal skills.
• Organized and strategic: Experience with software design, design patterns, and software architecture
• Collaborative mindset: Strong self-motivation towards PassiveLogic’s mission to “empower people through generative autonomy to solve the world's largest climate challenges.”
• Adaptability: Comfortable in a fast-paced startup environment, eager to learn, iterate, and innovate.
• Problem solving: You own this role. When issues arise, be the empowered force that solves them, rolling-up.

You should have

• Experience with:
  • Concurrency, threads, processes, Lib-dispatch/GCD
  • GPU programming, high-performance computing, and scientific computing
  • Vector, SIMD, and tensor computational methods
  • Strong math, numerical methods, and analysis skills

It’s helpful to have

• A relevant educational background: A BS, MS, or PhD in software engineering, computer science, applied mathematics, physics or other engineering degrees.
• Varied programming and domain experience: Experience with the Swift programming language, auto-differentiation, systems modeling and algorithm development, fundamentals of building energy or electromechanical systems, and/or autonomous systems.
• Familiarity with the startup environment: Experience working and collaborating in a startup.

We know there are candidates who might not fit everything we’ve described above, or who might have experience and skills we haven’t considered. PassiveLogic can sometimes be flexible enough to shift responsibilities to the right person, or otherwise identify open or upcoming roles that may better fit your professional background. Even if you don’t meet all the requirements above, we still want to hear from you.

Compensation, Benefits & Perks:

• Competitive compensation
• Generous equity share package
• Medical, dental and vision coverage
• Disability and life Insurance options
• Flex PTO
• Team-building events
• Free catered lunch in the office Monday — Friday
• Free ski pass (We are at the base of Big Cottonwood Canyon)
• Free National Park pass

When applying, include:

• A cover letter telling us why you're the perfect candidate for PassiveLogic
• A resume
• Extra mile — include a description of a project (of any type) you personally created, devised, built, managed, organized, or designed that was of your own self-initiative

Diversity and inclusion

Diversity, inclusion, and belonging is woven into our values and everything we do. We welcome all—come as you are and bring your whole self. We are proud to be an Equal Opportunity Employer. We celebrate diversity every day by maintaining a safe and inclusive environment for our employees at every stage of their careers.
