New JD for software engineers: Loop Engineering Boris Cherny, who built Claude Code, said: "I don't prompt Claude anymore. I have loops running that prompt Claude and figuring out what to do. My job is to write loops." Straight out of latest newsletter, another good summary of how engineers' roles are shifting...

Especially in the async organization like Babylon Labs, where I have colleagues in 10+ time zones.

What we learned from trying to turn vibe-coded prototypes into production SaaS applications Founder here. While developing MCPBackend, we noticed a major difference between generating a convincing application demo and building a maintainable SaaS product. AI coding tools are increasingly capable of generating interfaces, routes and even initial application logic. But a production application still needs: a reliable data model authentication and authorization backend validation
