The Role Commure is hiring a Staff Software Engineer (8+ years backend, 3+ years building financial systems from 0 to 1) who has built a double-entry payment ledger and has deep expertise in accounts and ledgering: payments, billing, reconciliation, ledgers or accounting. You will own the full architecture of money-critical systems at scale, with immutable, event-oriented data models where correctness is non-negotiable. What You Will Do Design and operate a double-entry payment ledger and the next-generation account and ledger model, with invariants that make it structurally impossible to "print money". Own the full money path: insurance ledger, posting and adjustment engines, patient account ledgers, bank reconciliation and AR reporting. Reconcile billed charges, payer remittances, bank deposits and financial reports, and surface discrepancies before customers do. Scale idempotent, explainable posting pipelines using negation/reversal semantics. Operate money-critical systems on very large Postgres tables with safe migrations, projections, backfills and incident response. Set the bar for observability and operational readiness, and mentor senior and staff engineers.
