THE ROLE
Own entire product surfaces across Ridicar and Be-jib — from data model to interaction detail, shipped weekly to real users in multiple markets.
INTFRAME is a small senior crew designing, building and operating AI-native products — Ridicar, Be-jib and Velthos — across multiple markets, on our own infrastructure. No layers, no theater: you ship real things to real users, weekly.
WHAT YOU'LL DO
- Own features end-to-end across two live products — schema, API, interface, rollout.
- Design systems that agents operate as first-class users, not just humans.
- Drive performance and reliability of production services running across four languages.
- Raise the engineering bar: code review, testing strategy, observability.
WHAT YOU BRING
- 5+ years building and operating production web services.
- Deep TypeScript — React/Next.js and Node at scale.
- Strong data modeling and API design; comfortable owning PostgreSQL.
- A track record of shipping: features delivered to real users, not slide decks.
NICE TO HAVE
- Experience embedding LLM and agent workflows into product.
- Multi-market or i18n products; SEO-aware engineering.
- Self-hosted or bare-metal infrastructure experience.
