Teams at Sauna

Build and operate Sauna’s stateful agent runtime, including session state, tool-call retries, timeouts, concurrency, actor-versus-job execution, and recovery across deployments. Develop production backend systems that resume interrupted work, trace runtime failures, and support long-running processes through code releases. The role requires hands-on TypeScript development using Cloudflare Workers, Durable Objects, Postgres, and Docker.

Own and build Sauna’s product experience across web and other interfaces, with a frontend-focused full-stack role. Design and ship delegation, memory, routines, collaboration, onboarding, billing, and high-performance local-first features. Work across interaction design, React architecture, APIs, database migrations, analytics, realtime systems, caching, and optimistic updates. Candidates should independently turn rough ideas into polished products, iterate from feedback, and care deeply about usability, performance, and craft.

Own the technical systems supporting customer acquisition and growth, including conversion tracking, attribution, integrations, funnel experiments, analytics, and internal automation. Build website experiences in TypeScript and React, analyze funnels and cohorts with SQL and PostHog, reconcile marketing and billing data, and run statistically sound experiments. Partner with marketing and product teams, maintain reliable event instrumentation, document decisions, test releases, and monitor production systems.
