Are you interested in the intersection of differentiable programming, software engineering, and computer science? Are you interested in developing innovative solutions to enable the next generation of Autonomous Systems? PassiveLogic is looking for a highly motivated and dedicated candidate who wants to learn from the best and stretch their skills. About PassiveLogic ® PassiveLogic is the first fully autonomous platform for buildings. We’ve reinvented the fundamental principles of automation to democratize technology, optimize buildings, and reduce the world’s carbon footprint. We are a team of technologists, engineers, and creatives dedicated to making a sustainable impact through real-world solutions. We are looking for team members who have a passion for technology and want to work on cutting-edge problems with real-world solutions. Our culture is built on bringing together the most talented engineers, thinkers, and creatives—backed by the world’s leading investors—working together to make the future a reality. 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 AI team developing 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. Collaboration: 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: Code performance and memory optimization 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 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.
