Senior Software Engineer - Application Wizard, aka Application Engineer Are you driven by curiosity and obsessed with building technology that hasn’t existed before? Do you want to engineer systems that fundamentally change how buildings think, adapt, and operate? At PassiveLogic, we’re redefining autonomy and energy efficiency from the ground up—and we’re looking for a Senior Application Engineer ready to build real-world systems that move the needle on sustainability at scale. 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 deployable solutions. We are looking for team members who have a passion for technology and who want to work on cutting-edge problems with real-world applications. Our culture is built on empowering people through generative autonomy to solve the world’s largest climate challenges. Backed by the world’s leading investors, our team works daily to make the future of smart cities 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 our Senior Application Engineer, you’ll play a pivotal role in building an ecosystem of local-first web applications that enable PassiveLogic’s autonomous systems platform. Our software applications enable users to collaboratively create physics-based models of the components from which autonomous systems are comprised, simulate the buildings in which autonomous systems will run, and generatively design autonomous systems with a human-centered interface to interact with their systems — no more black box AI. We empower people to use AI to improve their work, and we encourage anyone who takes on this role, to be open to improving their skills and their skills in using AI! At its core, our ecosystem is powered by Quantum , a schema for describing autonomous system Digital Twins , and DataSync, a real-time protocol for graph-based client/server data synchronization. We use empathetic Human-Computer-Interface (HCI) principles in our design, and TypeScript, WebGL, SVG, and reactive dataflow in our code. As part of our long-term vision, we are developing constraint-based layout engines, AI-enabled generative design capabilities, and exploring the use of Swift compiled to WebAssembly to improve the usability of our code across many platforms.
