Systems & Software QA Engineer (Integration & Validation)

The Systems & Software QA Engineer is responsible for ensuring the quality, reliability, and performance of software applications and their integration with hardware devices and networked environments. This role combines modern software quality assurance practices with hands-on system, device, and network validation.

The ideal candidate brings strong experience in test design, automation, and defect analysis, along with the ability to validate software within real-world environments including device interaction, barcode systems, and network configurations. This is a highly technical, individual contributor role critical to delivering high-quality, integrated solutions to customers.

This role is ideal for a QA professional who thrives at the intersection of software and systems—someone who enjoys both building automated test frameworks and validating how software performs in real-world, device-driven environments.

Candidates may come from either a strong software automation background with exposure to systems testing, or a systems/device testing background with growing experience in automation.
