Founding Engineer at Nessie

We are building the system of record for AI-native knowledge work. Nessie auto-syncs AI conversations across every major provider and structures them into queryable, trustworthy context for humans and agents. We are two people. We have years of runway. We are backed by YC, BoxGroup, Pioneer Fund, Precursor, and more. We are looking for one engineer who can build. You have shipped something real. Something with users, or something you use every day because you made it for yourself. You know what it feels like to go from nothing to working software and you have done it more than once. You are comfortable across the stack. Our codebase is Swift/SwiftUI (macOS app), Go (backend infrastructure), and TypeScript (services). You do not need experience in all of these. You need to be the kind of person who picks up what they need and figures it out. You reach for AI tools instinctively. You build with Claude Code, Cursor, Codex, or similar - and you are faster because of it. If your first instinct under pressure is to stare at the code instead of giving it to an agent, this is not the right fit. You will be working at the frontier of AI memory, context retrieval, and knowledge infrastructur
