Job description

JD: As a Lab Infra Engineer, you will play a critical role in the Systems Engineering function, supporting prototype bring-up, test execution, device farm operations, and cross-functional engineering efforts. You will act as the backbone of lab operations, ensuring devices and infrastructure are always ready for testing and validation cycles.

Prototype Device Setup & Lab Operations

• Set up, configure, and maintain prototype hardware devices and test systems.
• Support device provisioning, firmware flashing, and configuration changes requested by engineering teams.
• Maintain lab infrastructure including racks, devices, cables, and power/network connectivity.

Device Farm & Test Infrastructure Support

• Manage and monitor prototype device farms used for automated testing workflows.
• Ensure systems are test-ready and operational for continuous integration (CI) pipelines.
• Perform manual intervention when automated systems fail or require remediation.

Testing & Validation Support

• Execute hardware, firmware, and system-level test procedures across devices.
• Support debugging test failures by isolating hardware vs software issues.
• Assist in validation activities covering functional, regression, performance, and reliability testing.

Troubleshooting & Issue Triage

• Investigate and troubleshoot device failures, connectivity issues, and test anomalies.
• Work with engineering teams to capture logs, perform root-cause analysis, and escape defects.

Lab Maintenance & Operations

• Maintain lab cleanliness, organization, and safety standards.
• Track inventory of devices, cables, and consumables; support calibration and maintenance schedules.
• Document configurations, issues, and test results accurately.

Cross-Functional Support

• Collaborate with Systems Engineering, Firmware, Hardware, and Infrastructure teams.
• Support rapid prototyping cycles and bring-up activities for new hardware platforms.
• Assist engineers during debug sessions, experiments, and validation cycles.
• Work with third-party vendor team and internal stakeholders for any HW equipment and accessories.
