Why Vizcom

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

The Role

As the Senior Software Engineer – Backend (Systems / Infrastructure) yYou’ll architect and deliver backend systems that keep Vizcom fast, reliable, and scalable as our workload and customer base grow. You’ll work on everything from queueing GPU workloads to optimizing GraphQL resolvers and streaming realtime events. You’ll have deep ownership over APIs, performance, and data integrity — while collaborating with frontend and AI teams to enable magical experiences. Within your first 90 days you will: ship one critical backend feature (e.g., model queue, caching layer, or realtime service), reduce p95 latency in one major API path by ~30%, Author one technical RFC proposing an improvement to architecture or reliability, Implement or document one observability improvement (metrics, traces, alerts).

Compensation
$195,000 - $225,000 annually + Offers Equity

What You’ll Do

Design and implement scalable APIs in TypeScript/Node with GraphQL and Postgres
Profile and optimize slow paths — queries, resolvers, and I/O
Build and operate distributed systems: job queues, streaming, caching, and observability
Collaborate with AI engineers to integrate GPU inference pipelines into user workflows
Improve reliability: lead incident reviews, strengthen CI/CD and deployment flows
Mentor teammates on backend architecture, testing, and performance thinking

The Problems You’ll Tackle

Distributed GPU inference and queueing with bursty workloads.
Realtime synchronization with WebSocket and CRDT-based collaboration.
GraphQL performance: caching, batching, resolver optimization.
Secure multi-tenant data boundaries and enterprise integrations (SSO/SAML/SCIM).

Our Stack (today)

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.

Qualifications

5–8+ years building production web systems (TypeScript/Node or similar)
Strength in databases, performance tuning
