Responsibilities

The Opportunity

We’re hiring a Manufacturing & QA Engineer to lead the test, provisioning, and outbound processes for our next-gen IoT tracking tags. You’ll manage everything from factory-level validation to secure key injection, final QA, and shipment readiness. This is a mission-critical, hands-on role that ensures every device we ship is reliable, secure, and ready to deploy.

You’ll work alongside RF engineers, embedded developers, and our GM of Hardware to stand up clean, repeatable processes that scale—from single units to full-rate production.

What You’ll Do

• Develop and manage test plans, QA procedures, and factory validation workflows.
• Build and maintain test fixtures, scripts, and semi-automated tools to ensure performance and reliability.
• Lead the secure provisioning process, including FIPS 140-3 compliant key injection, secure boot config, and device personalization.
• Manage serialization, traceability, and production records for each shipped device.
• Work closely with contract manufacturers to validate output, drive yield improvements, and support line bring-up.
• Conduct root cause analysis and lead corrective action efforts for field or factory failures.
• Coordinate final QA checks, packaging, and logistics handoff to ensure devices leave ready for mission use.
• Collaborate with design, firmware, and ops teams to optimize for manufacturability and field-readiness.

Qualifications

What We’re Looking For

• 3–6 years of experience in hardware manufacturing, QA, or test engineering.
• Hands-on experience with embedded systems, RF devices, or low-power IoT hardware.
• Familiar with oscilloscopes, spectrum/network analyzers, signal generators, and power measurement tools.
• Comfortable building and documenting provisioning workflows, especially around cryptographic key injection and secure configuration.
• Strong understanding of DFM/DFT and how to translate test data into design feedback.
• Experience working with contract manufacturers, EMS providers, or pilot-scale production lines.
• S. Citizenship with the ability to obtain and maintain a government security clearance.

Bonus Points For

• Experience with secure hardware provisioning, FIPS 140-3 workflows, or key management.
• Knowledge of MIL-STD testing, IP67/IP68 enclosures, or ruggedized product requirements.
• Familiarity with tools like Python, Bash, or Node.js for test automation or provisioning.
• Experience creating or managing traceability systems for serialized hardware products.
• Exposure to packaging and logistics workflows for secure hardware delivery to DoD customers.

Why This Role Matters

When a device hits the field, it has to be bulletproof—and secure. You’re the final line of defense between the bench and the battlefield. If you thrive on precision, reliability, and delivering real capability, this is your role.
