Job Description

Senior Backend Engineer role. You'd work across our SvelteKit app (Postgres, Redis, Docker, ClickHouse), Python ML inference on GPU clusters, and Kubernetes clusters across multiple cloud and GPU providers. Notable projects include canary deploys with cookie-sticky traffic splitting; durable execution for long-running workflows; API design with OpenAPI docs auto-generated from Zod schemas; and enterprise-grade authentication/authorization/permissions. We value first-principles engineering and UNIX principles. GPU infra experience is a plus. Onsite in San Francisco; this posting is for a single Senior Backend Engineer role (not multiple roles).
