We have thousands of customers who rely on us for production AI workloads, including Lovable, Scale AI, Substack, and Suno. We're a fast-growing team based out of NYC, SF, and Stockholm. We've hit 9-figure ARR and recently raised a Series B https://modal.com/blog/announcing-our-series-b at a $1.1B valuation. Our investors include Lux Capital https://www.luxcapital.com/, Redpoint Ventures https://www.redpoint.com/, Amplify Partners https://www.amplifypartners.com/, and Elad Gil https://eladgil.com/.

THE ROLE: We are looking for strong engineers with experience and interest in designing, building, and maintaining the novel, high-performance systems that make up our serverless platform. REQUIREMENTS: - 5+ years of experience writing high-quality production code - Experience building high-performance distributed systems at a large scale (the more battle scars, the better) - Strong cloud skills - Strong knowledge of low-level operating system foundations (Linux kernel, file systems, containers, etc.) - Experience with performance engineering (tell us a story of when you shaved off a few milliseconds!) - Ability to work in-person in our Stockholm office. - Prior experience with Rust is nice to have, but not required. - Ability to participate in on-call rotation and respond to production incidents.
