Founding Software Engineer (Full-Stack)

StarSling (YC X25) We’re looking for a Founding Software Engineer (Full-Stack) to join our team in the San Francisco Bay Area. 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. Earlier in my career I was an engineer on Facebook’s AI Camera team and helped build the mobile computer vision library that currently powers camera effects for 100M+ DAUs across IG, FB, and WhatsApp. 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 40 million developers. What You’ll Own

Event-driven backend: Architect our Node.js / Next.js / TypeScript and Supabase stack. 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. 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. This IS for you if

You’re a full-stack 0-to-1 builder who has shipped to production. You have a genuine curiosity about agentic product experiences and are excited about understanding the impact of AI on engineering users. You’re a previous founder or founding engineer. You’re unusually obsessed with hard problems. You’re comfortable with ambiguity and adapting to dynamic priorities. You have excellent communication and candor. You care about helping swamped engineers fight through the schlep of software development. You have grit and perseverance. This IS NOT for you if

You’re not based in The Bay Area. You’re not willing to work six days per week. You’re not excited about using codegen tools like Cursor, Windsurf, Claude Code, etc. You’re not comfortable deleting 80%-90% of the code that you write. You’re not comfortable with ambiguity and rapid context-switching. You don’t like candor- receiving and giving direct, honest feedback. You need a well defined structure or career ladder. The Opportunity

Work alongside two experienced co-founders. Get experience across the startup stack. Be the first employee of the next dev tools category leader. Base pay range

$150,000.00/yr - $190,000.00/yr Seniority level
