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
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).
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.
5–8+ years building production web systems (TypeScript/Node or similar)
Strength in databases, performance tuning, and distributed systems
Experience operating Kubernetes or similar orchestration environments.
Fluency with observability tools and debugging live systems.
Bonus: GPU workloads, background job systems, or realtime architectures.
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.
