Senior Software Engineer – Frontend (React /WebGL)

Our mission is to reshape design by streamlining the path from concept to creation, bringing more impactful ideas into the physical world.

We’re well-funded (Series B $51m to date), growing double-digits MoM, and expanding the core engineering team in SF. The surface area is big: realtime collaboration, GPU inference at scale, a modern TypeScript stack, and serving real enterprise

As the Senior Software Engineer – Frontend (React /WebGL) you’ll own major product surfaces in Vizcom’s real-time design environment — from our canvas rendering engine to collaborative UX systems. You’ll work across React , WebGL , and GraphQL , shaping performance, interaction design, and developer experience. You’ll partner closely with designers, AI engineers, and backend leads to make Vizcom’s interface both beautiful and blazingly fast. Within your first 90 days you will: ship one new or re-architected user-facing feature that improves product performance or fidelity, establish a render or collaboration performance baseline (e.g., frame rate, latency, bundle size), propose or contribute to frontend tech direction (e.g., render pipeline abstraction, UI state model), and reduce one persistent performance or UX friction point across the frontend stack.

Build rich interactive surfaces: own features that blend design, collaboration, and 3D visualization

Optimize performance: push React and WebGL rendering to feel instant under load

Craft developer ergonomics: shape component architecture, hooks, and state models that scale

Collaborate early with Design: prototype fast, test feel, and bring high-fidelity UX to life

Improve observability : instrument and debug perf metrics (FPS, React profiler, network traces)

Mentor teammates: review code for clarity, structure, and maintainability

High-fanout realtime collaboration with CRDT-style data models

Rendering pipelines in WebGL/WebGPU , balancing fidelity and speed

Bundle optimization, lazy loading, and Vite build performance

Complex interaction logic that must still feel intuitive and instant

Frontend: TypeScript, React, Vite, WebGL; realtime collaboration.

API/Backend: TypeScript/Node, GraphQL (PostGraphile), Postgres, Redis, background workers.

Infra: Kubernetes, Pulumi, CI/CD with GitHub Actions, Datadog for observability, feature flags.

Security/Enterprise: SSO/SAML (WorkOS), SOC 2-minded practices.
