CalAmp’s K-12 transportation platform tracks the buses that move ~1 million students every school day across 400+ North American school districts. We run Microsoft SQL Server self-hosted on AWS EC2 — 9 production instances, 600+ customer databases, more than a billion rows of operational data, and growing. (An eventual move to AWS RDS is on the table as a future direction, not a near-term plan.)
We’re hiring a hands-on Database Engineer with strong production experience who is ready to grow into architecture, automation, and modern engineering practices.
Responsibilities
What you'll work on
Performance — the daily craft. Diagnose and fix slow queries, plan regressions, and locking storms across 9 SQL Server instances supporting customer-facing operations. You’ll inherit a decade of accumulated SQL — your first 90 days are about understanding it before re-architecting it.
Reporting replica architecture. We need to separate analytical workload from operational SQL Server before it costs us customer SLAs.
You’ll lead the design — likely AWS DMS feeding a multi-tenant Aurora PostgreSQL store, but the call is yours after scoping. This is a flagship project, not a maintenance task.
Archival. Sound data retention strategy across 600+ customer DBs that doesn’t degrade restore-from-backup integrity. You’ll define the policy and own the automation.
AWS cost. SQL Server EE licensing on EC2 isn’t cheap. There’s measurable savings on the table for a DBA/Database Engineer who knows where to look — edition choice, reserved instances, right-sizing, replica strategy.
Schema migrations and ETL. Schema-change process across all customer DBs. Today this is partially manual; the goal is to make it automated, reliable, and low-risk.
Database SME for engineering — a core part of this role. You’re the subject-matter expert who reviews every schema change from developers before it ships, and you bring actionable design insight — not just approvals. Profile and optimize queries
