The work is slow, expensive, and error-prone, and it has barely changed in decades. Octozi is changing that. We are building the AI-powered review platform that pharma sponsors and CROs use to clean and review clinical trial data faster and more reliably than manual review. We have signed contracts with multiple pharma customers running live studies, and we are backed by a $3M seed round. Our recent paper documents what the platform achieves on real oncology trial data: 6x faster throughput, 6.4x fewer missed errors, 15.4x fewer false queries, and an estimated $5.1M in savings per Phase III trial. The numbers come from a hybrid architecture combining LLMs,...

What pbl is. pbl is the loop between climbers and their gyms. Climbers log sends and rate routes in the mobile app. Their gym sees all of it in real time in the portal: what climbers love, what gets quietly skipped, whether last week's set landed the way the setter hoped. Then they turn it into the next rotation. No one has built this before. The apps are built. The doors just aren't open yet. Real gyms are waiting. This hire is one of the last pieces before we ship. The role. You'd be pbl's second engineer, working the full stack with Dylan and Jake. Typescript everywhere. Next.js on the web, react native (expo) on mobile, firebase + gcp on the backend. Shared schemas flow to both apps from a central package, so the codebase stays consistent without duplication. Nothing is siloed. You'll touch the mobile app, the portal, the cloud functions, the schemas, and the deployment pipeline in the same week. Small enough that you'll get your hands on all of it. Big enough that...
