Equity 0.3 – 0.5%
Fluent Italian is a hard requirement: we work closely with Italian chartered accountants.
Who we are
We are a team of 5: the founding team (CEO, COO, CTO) and our first two employees (Marketing and Data Engineer). We have raised the funding we need to build and are targeting 7 people in the tech and product team by end of year.
You are the fourth technical hire and the first with an explicit architecture mandate: you define the foundations we will build on for the next 5 years.
The context
We are not building accounting software; we are building the deterministic half of an AI-native system. Agents propose, your services validate. Business invariants that hold across thousands of companies. Accounting operations that are architecturally impossible to get wrong.
As Staff Engineer you are the technical reference point for the team. You do not just write code; you set the rules: how we model the domain, how we design APIs to be consumed by autonomous agents, how we guarantee tenant isolation, how we capture every system decision for the audit trail.
-
- Accounting domain modeling: double-entry bookkeeping, multi-currency, immutable journal entries, accrual-basis fiscal state. Correctness is non-negotiable.
- Agent-first API design: structured responses, explicit error boundaries, stable contracts that an LLM can consume reliably. Not generic REST: APIs designed to be reasoned about by a machine.
- Multi-tenant isolation at scale: zero context leakage across thousands of companies. RLS, credential scoping, tenant-aware middleware.
- Event sourcing and audit trail: every accounting action is immutable, reversible only through a counter-entry. The log is the source of tru
