A B2B SaaS AI startup we partner with at Joppy is looking to hire a Senior DevOps / Site Reliability Engineer (SRE) to help scale and optimize its cloud platform and AI infrastructure.

This role focuses primarily on the platform roadmap, occasionally embedding within product squads while driving impactful improvements that affect every engineer. You’ll be hands-on, opinionated, pragmatic, and contribute code - this is not an ops-only position.
