Senior Software Engineer – Frontend

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.

*Experience with every item above is not required. What matters is that you are excited to shape it.

• 5–8+ years building and shipping complex frontend systems (React/TypeScript)

• Strong experience with WebGL, Canvas, or custom rendering engines

• Deep understanding of UI performance, profiling, and memory management

• Strong eye for design quality — you care about both pixels and milliseconds

• As a colleague, you enjoy planning, executing, winning and celebrating as a team

• Experience working remotely and/or in a startup environment

• Bonus: experience with GraphQL, WASM, GPU pipelines, or 3D scene systems

How We Work

• Small team, high ownership. Fewer people, more leverage.

• Design-centric. We obsess over speed and feel; “fast enough” usually is not.

• Write it down. RFCs, crisp decisions, living docs.

• Operate what you build. Everyone takes on-call support; incidents drive improvement, not blame.

• Intro (30m): mutual fit, role and impact.

• Architectural deep-dive (45m): product and design collaboration.

• Coding Session (45m):

• Onsite Interview (half day)

• References and offer.
