About Winixx

Winixx Inc. is a New York-based technology holding company operating a portfolio of over 30 SaaS platforms across freight, fleet management, financial infrastructure, and market intelligence. Founded with a mission to modernize fragmented and underserved industries, Winixx builds technology that removes inefficiencies, creates transparency, and puts more value in the hands of the people doing the actual work. Our flagship products include Winixx Freight, a next-generation load board with embedded instant payment;

fleetOS, a comprehensive fleet management and roadside assistance platform; and Baron Meddy Financial, our financial infrastructure arm facilitating capital deployment, escrow, and M&A advisory across verticals. Winixx is headquartered in Atlanta, Georgia, with remote teams operating nationwide.

Before any fleetOS hardware product ships to a carrier or fleet operator, it must pass through a rigorous validation program that subjects it to conditions more extreme than anything it will likely encounter in the field — because the cost of a validation program that is too easy is measured in field failures, warranty claims, and damaged customer relationships. The Hardware Validation Engineer at Winixx owns this validation program, developing the test plans, executing the tests, interpreting the results, and making the engineering judgments that determine whether a hardware product is truly ready for production release.

This is a role for an engineer with both technical depth and professional integrity — someone who will report validation findings accurately even when the results are inconvenient for program schedules.

• Develop comprehensive hardware validation test plans for each fleetOS hardware program, translating product requirements specifications into specific, executable test cases with defined test conditions, measurement methods, acceptance criteria, and pass/fail disposition rules
• Execute environmental, mechanical, and electrical validation tests on hardware prototype units, operating test equipment including temperature and humidity chambers, thermal shock chambers, vibration tables, salt spray chambers, IP/dust ingress test equipment, and electrical measurement instruments
• Perform electrical performance validation testing on fleetOS hardware, including power consumption measurement across operating states, cellular and GPS RF performance characterization, OBD‑II communication interface testing, and functional verification across specified operating temperature and voltage ranges
• Document all test activities and results in validation test reports that accurately record test conditions, raw measurement data, pass/fail determinations, and anomalies observed during testing, maintaining complete traceability between test results and the hardware units under test
• Investigate validation test failures with rigor and objectivity, performing root cause analysis to distinguish design deficiencies from test anomalies, sample outliers, and test setup issues, and documenting investigation findings with supporting evidence
• Manage the hardware sample traceability program for all validation activities, maintaining records that link each test result to the specific hardware unit tested, the hardware design revision under test, and the production lot and build date
• Support FCC, CE, E‑Mark, and automotive certification testing by preparing hardware samples to specification, coordinating with accredited test laboratories, and reviewing draft test reports
• Develop and maintain Winixx's hardware…
