• Diagnose and resolve field‑reported defects across custom SoC platforms (ARM), peripherals (I2C/SPI/UART, GPIO, USB, Ethernet), and networking stacks (TCP/UDP, multicast).
• Perform root cause analysis on production issues; develop and validate corrective actions through the full verification cycle.
• Lead HW/SW troubleshooting on fielded units using oscilloscopes, logic analyzers, JTAG, and trace tools.
• Lead sustaining engineering efforts on assigned product lines; mentor junior engineers, prioritize defect backlogs, and coordinate with product management on release planning.
• Manage component obsolescence and end‑of‑life transitions; evaluate, qualify, and integrate alternate parts with minimal design disruption.
• Maintain certification‑aligned software processes (requirements, design, code reviews, regression tests, verification evidence) for updates to fielded products.
• Collaborate across FPGA, hardware, manufacturing, quality, and field support teams to resolve cross‑functional issues and drive continuous improvement.

• Bachelor of Science degree in Computer Science or Electrical Engineering (BSCS, BSEE) or equivalent.
