Founding Engineer

About this role

Mesh is building AI agents for accounting teams — creating the ultimate connector for a company’s finance stack — giving accountants the power to map data across systems like engineers and enabling real-time visibility. We’re looking for a founding engineer to help build the core platform: Ingest and model messy event data Define and execute workflows that generate accounting outputs Build AI-powered tooling that finance teams actually trust You’ll work directly with the founders (ex-Carta, finance, infra) and be hands-on across the stack — from workflow engines and LLM interfaces to the orchestration layer that drives journal entry creation and reconciliation. Backed by $2M in seed funding from exceptional investors, we’re now focused on building out the founding team. We are looking to grow our team in San Francisco, and will help with relocation. You might be a fit if: You’ve built complex backend systems (event-driven, data pipelines, infra, etc.) You’re comfortable shipping fast, debugging hard problems, and iterating in a messy v0 You’re excited by the idea of owning core technical decisions and building from scratch Bonus: experience with accounting systems, financial data models, or AI agents Why join us now? We’re early — real customers, real revenue, but still pre-Series A You’ll have massive ownership in shaping both product and culture It’s a rare opportunity to reinvent workflows that every company on earth has YC-backed (W25), early design partners, and a team that deeply understands the problem
