Senior Backend Engineer

Job Description
- Own two or three services outright: schema design, deployment, dashboards, and the runbook somebody else reads at 03:00.
- Move the ledger write path from single-row inserts to batched idempotent upserts keyed on a client-supplied token, targeting 8,000 writes per second sustained on the existing three-node Postgres cluster.
- Design partitioning and retention for tables now past 1.2 billion rows, then run the migration online with no read downtime.
- Review 15-25 pull requests a week and hold the line on what gets merged.
- Share an on-call rotation of one week in six, and write the incident review when it was your service.
