Founding Engineer

About the role

About Mesh

Every company has operational systems that capture what happened across the business.

Every company has an ERP that records the financial outcome.

Between them sits something surprisingly fragile: the financial logic that determines how operational reality becomes financial truth.

Today, that logic lives in spreadsheets, approval chains, tribal knowledge, and the heads of experienced accountants.

Mesh is building the governance layer for financial logic. We ingest operational data, orchestrate AI and human workflows, apply company-specific accounting policies, and produce governed, explainable financial outputs that CFOs, controllers, auditors, and boards can trust.

We believe the governance layer for financial reasoning will become foundational infrastructure for every AI-native enterprise.

Why Mesh

Accounting is one of the last major enterprise workflows still held together by spreadsheets, not because the industry resists change, but because every business has thousands of edge cases that traditional software couldn't model.

Our founders have spent years building financial software alongside accounting teams.

Our moat isn't access to foundation models. It's the governance layer built on top: financial policy engines, workflow infrastructure, enterprise integrations, evaluation systems, audit trails, and years of accumulated customer knowledge.

The Role

We're looking for a Founding Engineer to help build Mesh from the ground up.

You'll work directly with the founders to architect the platform, talk to customers, design new product primitives, and ship systems that become the foundation of the company. You'll own problems end-to-end, from the first customer conversation to production.

We're intentionally building an unusually small team to solve an unusually difficult problem. We believe exceptional companies are built by exceptional builders, not large organizations.

What You'll Build

- Financial policy engines that translate accounting judgment into executable workflows.

- Agentic systems that gather evidence, coordinate stakeholders, and operate within governed approval boundaries.

- Workflow infrastructure connecting humans, AI, and enterprise systems.

- Spreadsheet interpretation and policy modeling that turns institutional knowledge into durable software.

- AI evaluation infrastructure for reliable, explainable production systems.

- Enterprise integrations and data pipelines across ERP, procurement, AP, HRIS, billing, and operational systems.

- Auditability and governance tooling that makes every financial decision explainable, reproducible, and trusted.

You'll work across backend infrastructure, AI systems, developer tooling, and enterprise product design.

What You'll Bring

Customer obsession — You start with the customer, followed by the architecture. You enjoy understanding how people actually work before deciding how software should work.
