Head of Engineering.

Every company is obeying a scaling law nobody measures. Revenue is the mass, and cost, capacity, cash and complexity each scale with it at their own exponent. Get the exponents wrong and you grow into a weaker company. No system tells you, because software was built to record what happened, not to decide what should.

Allometry measures those exponents from executed work and enforces a decision at the moment a company commits. The first product is a margin floor on quotes for physical operators: the price clears what the work truly costs today, or it does not leave without a human’s name on it. At our first design partner, a Quebec pallet manufacturer, ninety days of closed jobs surfaced approximately $300K in annualized margin leakage patterns. That goes live October 1.

Three things get built, in order. The Pulse, a continuous reading layer over the systems an operator already runs. The floor as a governed Tool. And the Ledger, an append-only record of expected against realized on every commitment. Everything after that, the company Profile, capital against the Ledger, and eventually agent-to-agent work routing, is an extension of those three rather than a rewrite.

Here is the honest part. There is a large codebase and most of it is a year of exploration. The go-to-market plumbing is real and used. The thing the thesis actually needs does not exist yet: no knowledge graph, no coefficient engine, no ledger, no data platform, no governed model workflow. The first job is a disciplined extraction, not a greenfield build and not a rewrite. You get the full state of the code, liabilities included, after a first conversation.

You own the Node. The object model, the Coefficient engine, the Tool registry, the Ledger, the Pulse, the model router, and the acceptance tests. Plus the weeding, which is most of the first six months.
You do not own the economics, the objective or the go-to-market. Those are the founder’s and the design partner’s.
You are judged on three things. The stage acceptance tests. Deployment time per operator trending down. Whether an investor can verify our claims without trusting anyone. Nothing else is a metric.
The stack. Next.js 16, React 19, TypeScript, Drizzle over Postgres, Clerk, Inngest, Vercel. The data platform is an open decision and yours to argue.

What we are looking for. Someone who has built a system where correctness mattered more than velocity and can say what that cost. Comfortable deleting code. Reads a specification and argues with it rather than implementing it silently. Wants the object model to be theirs; this is not a role that takes tickets. French and English is useful for the Québec operator base, not required.

The process. A conversation about the thesis, not a screen. Then the architecture brief with the honest state of the code. Then a working session on one real decision, the coefficient pooling problem or the extraction plan. Then references and an offer. No take-home; the working session is the signal.

The context, plainly. One founder, pre-revenue, real operating data from one design partner, a specification written down to the calculation, and no team. You would be the first engineer and the one who decides what the platform actually is.
