Comfortable standing up new tooling from scratch and retiring it when needs change.
Experience operating CI/CD infrastructure, particularly pipelines that run on physical hardware.
Understanding of hardware-in-the-loop testing, reliability testing, and certification testing methodologies.
Experience managing fleets of physical test cells or lab infrastructure (Ansible, AWX, or similar).

Experience with time-series data: ingestion, storage, and querying of telemetry.
Experience with PostgreSQL, S3/AWS.
Experience building reporting dashboards for engineering or leadership audiences.
