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
