Full-time
Hybrid
Mid, Senior Level
4+ years expPassiveLogic is a company that enables autonomy for controlled systems through innovative technology. They are seeking a Product Engineer for their Web Platform to build applications that make autonomous building systems understandable and interactive for users. This role involves developing interfaces for constructing models, simulating building behavior, and monitoring deployed systems.

Responsibilities
You'll build the applications that make autonomous building systems legible to humans
You'll build interfaces for creating, editing, and validating these models—work that combines structured data editing, spatial visualization, and domain-specific interaction patterns
You'll build the interfaces that display simulation results, highlight anomalies, and help users develop intuition about how their buildings will perform
You'll build interfaces that surface the right information at the right moment without overwhelming users with data they don't need
You'll work with distributed data patterns (conflict resolution, optimistic updates) that most front-end roles never encounter
Qualification
Required
Strong TypeScript and JavaScript fundamentals. You've built substantial applications in TypeScript, understand the type system deeply, and write code that other engineers can read and maintain
Experience with modern front-end frameworks. Angular, React, Vue, Svelte—the specific framework matters less than understanding the underlying patterns: component architecture, state management, reactive dataflow, change detection. You should be able to reason about why frameworks make the tradeoffs they do
Comfort with complexity. The applications we build aren't simple CRUD interfaces. You're energized rather than overwhelmed by domains with many interacting concepts. You can hold a mental model of a complex system and build interfaces that help users develop their own
Visual and spatial thinking. Much of our UI is graphical—building schematics, system diagrams, data visualization. You don't need to be a designer, but you should be comfortable reasoning about spatial relationships, visual hierarchy, and interaction in two (and sometimes three) dimensions
Attention to craft. You care about the details that separate adequate interfaces from excellent ones—animation timing, interaction feedback, edge case handling, performance under load. You notice when something feels slightly off and you fix it
Experience level. Typically 4+ years building front-end applications, with at least some of that time on complex, data-rich interfaces. We're looking for engineers who've moved past the 'making it work' phase into the 'making it right' phase
Preferred
Graphics programming—WebGL, Three.js, D3, SVG manipulation. We do a lot of this
Real-time data visualization or applications with live-updating state
Local-first or offline-capable application architecture
Domain experience in building systems, energy, IoT, or industrial software. (Helpful for intuition, but we'll teach the domain.)
Experience consuming platform APIs or working within opinionated framework architectures
Benefits
Competitive salary plus equity.
