Core Responsibilities

Primary Functions

Lead end-to-end hardware integration and system bring-up for new products: perform PCB bring-up, power sequencing validation, clocking and signal integrity checks, and initial functional verification to demonstrate working hardware systems.
Define, develop, and execute system-level test plans and verification strategies that validate hardware against product specifications, regulatory requirements, and customer acceptance criteria.
Perform complex hardware debugging using oscilloscopes, logic analyzers, spectrum analyzers, power meters, and protocol analyzers to isolate electrical, timing, and protocol faults across multi-board systems.
Collaborate closely with PCB design, schematic, and signal-integrity engineers to investigate and resolve issues discovered during integration (e.g., EMI, ground bounce, coupling, termination, impedance mismatches).
Integrate and validate firmware and device drivers with hardware platforms; work with firmware teams to triage boot issues, memory map mismatches, and peripheral initialization problems.
Design, implement, and maintain automated test frameworks and test harnesses for functional regression, burn-in, and environmental testing using Python, LabVIEW, Jenkins, or other CI/CD tools.
Create and maintain bring-up and debug documentation, runbooks, alignment guides, and troubleshooting procedures to accelerate reproducible integrations and cross-team knowledge transfer.
Drive root-cause analysis for failures found during lab validation, environmental testing, and pre-production runs; implement corrective actions and verify fixes across hardware and firmware layers.
Support qualification and certification activities by providing test evidence, traceability, and reproducible test setups for EMC/EMI, safety, thermal, and environmental compliance testing.
Coordinate and execute manufacturing engineering(s) handoff: define test points, in-circuit test (ICT) requirements, functional test flow, boundary-scan strategies (JTAG), and fixture specifications for production.
Develop and execute validation plans for interfaces and protocols (Ethernet, PCIe, USB, CAN, MIPI, SPI, I2C, UART), ensuring interoperability with host systems and peripherals.
Implement design-for-test (DFT) and design-for-manufacturing (DFM) recommendations during prototype and pre-production stages to minimize field failures and test cycle time.
Perform performance characterization and benchmarking (power consumption, thermal behavior, RF/analog performance) and provide quantitative reports for product leadership and stakeholders.
Manage test equipment, lab assets, and fixture development; specify procurement of specialized instruments and coordinate maintenance/calibration schedules.
Collaborate with firmware, software, and QA teams to develop system-level regression suites and automated nightly builds that exercise hardware edge-cases and long-duration stability.
Troubleshoot intermittent issues in deployed systems by reproducing customer-reported defects in the lab, analyzing telemetry, and driving firmware/hardware fixes through cross-functional teams.
Mentor junior engineers and technicians in best practices for hardware integration, lab safety, test automation, and root cause investigation methodologies.
Participate in sprint planning, design reviews, and gate reviews to ensure integration requirements are captured, risks are mitigated, and test coverage is sufficient before release.
Provide on-site and remote support for first-article builds, pre-production validation runs, and customer integration activities; travel to manufacturing or customer sites as required.
Maintain and continuously improve integration processes, checklists, templates, and KPI tracking (first pass yield, MTBF, test coverage) to improve time-to-market and product quality.
Evaluate third-party modules, daughtercards, and off-the-shelf components during integration to validate interoperability, power budgets, and thermal constraints.
Ensure secure handling of IP and sensitive hardware artifacts during bring-up and validation phases; enforce company policies on lab access and documentation control.

Secondary Functions

Support ad-hoc data requests and exploratory data analysis.
Contribute to the organization's data strategy and roadmap.
Collaborate with business units to translate data needs into engineering requirements.
Participate in sprint planning and agile ceremonies within the data engineering team.
Assist in vendor qualification and technical supplier reviews for components and test equipment.
Provide input to product requirement documents (PRDs) from an integration and testability perspective.
