Founding Engineer

We’re looking for one engineer who can build. You’ll work at the frontier of AI memory, context retrieval, and knowledge infrastructure, and own real surface area from day one. We’re two people with years of runway, so you’ll have enormous autonomy and you’ll ship constantly. And because we’re a tiny team, the role is broad: alongside building, you’ll pick up internal ops, customer relationships, and whatever moves the company that week. The heart of it is building.

What "build" means here

• You have shipped something real: something with users, or something you use every day because you made it for yourself. You have gone from nothing to working software more than once.
• You’re comfortable across the stack. Our codebase is Swift/SwiftUI (macOS app), Go (backend), 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.
• You reach for AI tools instinctively (Claude Code, Cursor, Codex) and you are faster because of it. If your first instinct under pressure is to stare at the code instead of handing it to an agent, this is not the right fit.

What you will work on

Core engineering

• Cross-platform conversation sync across many AI providers, the hardest unsolved capture problem in the space
• Search and retrieval that makes thousands of conversations queryable in milliseconds
• Ontology and knowledge structuring: turning messy conversational material into trustworthy, typed knowledge
• AI governance: team sharing, permissions, and policy. This is what turns Nessie from an individual tool into the context layer for a whole organization.
• Agent-facing APIs (CLI, MCP) that let any AI tool reach accumulated human reasoning
• Self-hosted and on-prem deployments, plus the security and compliance that come with them, as we move into larger and more regulated organizations
