Senior Software Engineer

Senior Software Engineer - Application Engineer

Are you driven by curiosity? Do you have a passion for developing groundbreaking  technologies that drive sustainable building systems? Are you excited by the opportunity to shape solutions that transform the way we think about energy efficiency and automation? PassiveLogic is seeking a Senior Application Engineer to join our dynamic team!

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.

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.

What you’ll do

Design and Implement Front End Architecture: Lead the design and implementation of front end architecture to support native-quality web applications for multi-platform deployment.

Contribute Across Teams: Collaborate cross-functionally to build our technology and celebrate our shared successes. Be impact-driven, seek to be a good employee, neighbor, and global citizen.

Optimize Systems-level Performance: Be a systems-level thinker who researches before they act and values sound processes and broad thinking.

Prioritize Execution, Stability, and Velocity: Focus on delivering short-term wins while maintaining a long-term vision within our shared architecture. Take pride in the impact of our products and in delivering a "wow" customer experience.

Nerd Out About Your Craft: Dive deep into the details and continuously refine your expertise.
