PassiveLogic Get AI-powered advice on this job and more exclusive features. Are you passionate about pushing the boundaries of 3D visualization? Do you thrive on turning complex spatial data into intuitive, interactive experiences? PassiveLogic is seeking a creative and performance-minded 3D Application Developer to help us define the next generation of building automation tools.
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 our 3D Application Developer, you will build responsive, immersive, and high-performance interfaces that bring our building digital twin technology to life through interactive, through interactive 3D modeling environments.
What You’ll Do
Build performant, interactive 3D environments:
Design and implement 3D UIs using WebGL and Three.js for our ecosystem tools, allowing users to visualize and interact with smart buildings and their components.
Optimize complex scenes and assets:
Use techniques like spatial indexing, mesh instancing, level of detail (LOD), lazy loading, and GPU-efficient rendering strategies to keep frame rates high even in heavy scenes.
Enable intuitive 3D user interaction:
Implement robust mechanisms for object selection, manipulation, and feedback using raycasting, hit detection, and UI overlays—so users can edit, query, and simulate system behavior fluidly.
Collaborate across cloud and AI systems:
Work with backend teams using Swift Vapor, GraphQL, Kubernetes, and PostgreSQL to create synchronized multi-user visualizations and real-time updates of shared 3D models.
Lead user-focused visualization strategy:
Bring in data visualization frameworks like D3.js to enhance interaction with graph data and system feedback in 2D/3D hybrid interfaces.
Bridge art and engineering:
Act as a key liaison between product design, engineering, and user experience teams—translating rich data models into beautiful, clear, and usable visual tools.
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: 5+ years building interactive apps with Three.js, WebGL, or similar 3D engines in a performance-critical environment. Exceptional communication skills: You can clearly explain 3D systems, rendering tradeoffs, and architectural decisions to technical and non-technical teams. Organized and strategic: Strong ability to architect scalable rendering pipelines and break down large UI/UX systems into manageable, well-tested modules. Collaborative mindset: Enjoy working closely with product managers, designers, and backend engineers to ship beautiful and functional user experiences. 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
Strong grasp of rendering optimization: You’ve tuned shaders, compressed textures, and decimated meshes for speed. Hands-on data viz experience: Familiar with D3.js or custom canvas/SVG-based approaches for interactive visualizations. Experience building collaborative 3D tools: You’ve worked on multiplayer or real-time collaborative editing platforms before. Familiarity with backend sync layers: Bonus if you've dealt with WebSockets, CRDTs, or pub/sub systems to manage live, shared data.
It’s helpful to have
Building automation or IoT experience: Understanding of BIM, HVAC systems, or sensor networks. Autonomous systems or AI integration experience: You’ve worked with ML-driven 3D tools or interactive simulation platforms.
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.

A Note on Working Onsite:
This role is based in our Salt Lake City headquarters. We believe that creativity and cohesion flows best when we are all together. When you’re constantly innovating, transforming whole industries, inventing new products and processes, and creating a more sustainable future through technology—and we are doing all these things—we believe we’re better as a team in-person. That’s why all of our teams work from one of our office locations, five days a week.
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
