We’re looking for a Founding Software Engineer (Full-Stack) to join our team in San Francisco, CA. We're focused on solving a big problem : how to make all the annoying tasks outside of your code editor fully agentic; everything from deployment to performance, incidents, and bugs.

You'll be working directly with me (Daniel). Before StarSling, I was the Engineering Manager at Netflix working on the most used internal tool for their 3K+ engineers and tens of thousands of microservices — an internal developer portal called Netflix Console. I’m obsessed with helping every engineer be more productive.

You’ll also be working directly with my co-founder Yonas. Before StarSling, Yonas was the Founder & CEO of StackShare, a developer community used by over 1.5 million developers. He raised $12M as a first-timer and did founder sales to get them to just under $1M ARR with their enterprise product before selling the company last year. He’s obsessed with creating product experiences that developers love and building community.

What You’ll Own

• Event-driven backend : Architect our Node.js / Next.js / TypeScript and Supabase stack. Design schemas, event flows and ingest dev tools webhooks to power a real-time personalized engineering portal.
• LLM Agentic Workflows : Build a system of agents — MCP, tool use, memory, retry logic, context updates, feedback mechanisms.
• Agent Experience (AX) : Create intuitive product interfaces for human-agent interactions. Explore and iterate with engineers to find the right interaction paradigm to productivity work with a digital co-pilot.
• System Design & Technical Strategy : Work directly with me to determine the best technical path that balances moving fast and scaling to many customers using different dev tools. Determine how we integrate and support the open-source community.
