Job Overview

We are looking for a Senior Electronics Engineer with deep expertise in PCB reverse engineering, embedded systems, and component-level diagnostics to drive the analysis, repair, and modernization of complex electronic assemblies. This role requires a hands-on engineer capable of reconstructing schematics, developing firmware, and implementing robust test and validation methods to support high-reliability repair operations. You will work cross-functionally to enhance legacy systems, optimize repair processes, and ensure seamless hardware and firmware integration, including advanced display and touchscreen technologies.

Responsibilities and Duties

• Reverse engineer multi-layer PCB assemblies, including schematic reconstruction, signal tracing, component identification, testing, and circuit simulation.
• Apply deep expertise in LCD/LED display systems, touchscreen technologies, and digitizer integration to support design, debugging, and system performance.
• Reverse engineer products from Original Equipment Manufacturers.
• Lead root cause analysis and advanced troubleshooting of failed or intermittent boards.
• Develop automated test setups for diagnostics, board validation, and long-term performance analysis.
• Redesign and modernize legacy circuit boards using current components while maintaining backward compatibility.
• Collaborate with firmware, mechanical, and production teams to ensure seamless board-level integration and repair.
• Mentor junior engineers and technicians on repair techniques, firmware programming, and effective troubleshooting practices.
• Optimize board repair processes to reduce costs, minimize downtime, and improve first-pass yield rates.
• Partner with vendors and suppliers to source equivalent or improved component replacements.
• Provide engineering support for production, service, and field teams during critical failure or redesign projects.
• Develop comprehensive documentation for reverse-engineered circuits (netlists, BOMs, schematics) and produce clear training materials and step-by-step guides for repair, reprogramming, and requalification of circuit boards.
• Occasional travel for field testing and product analysis.

Qualifications

• Bachelor’s degree in Electronics Engineering, Electrical Engineering, or a related field.
• 4+ years of experience in circuit board reverse engineering, embedded firmware development, and board-level troubleshooting.
• Proficiency in C and Python for embedded software development on microcontroller platforms (e.g., ARM Cortex-M, STM32, RP2040, ESP32, Microchip PIC).
• Experience developing and debugging systems using RTOS, device drivers, and low-level hardware interfaces.
• Proficiency with lab equipment such as oscilloscopes, multimeters, logic analyzers, and JTAG/debuggers.
• Hands-on experience with rework stations, including soldering and desoldering of components.
• Practical experience with communication protocols such as Ethernet, UART, I2C, SPI, CAN, and USB.
• Ability to create technical documentation to support hardware analysis, redesign, and troubleshooting.
• Strong analytical and problem-solving skills with a structured approach to failure analysis.
• Excellent communication and mentoring abilities.

Preferred Qualifications:

• Hands-on, solutions-oriented engineer with a strong passion for diagnosing, repairing, and enhancing legacy electronic systems at the component and system level.
• Proven ability to perform in fast-paced, high-throughput environments such as repair centers, refurbishment operations, or service organizations, where quality, turnaround time, and customer satisfaction are critical.
• Experience using project management and collaboration tools (e.g., Gitlab, Wrike) to effectively track tasks, prioritize workloads, and coordinate across cross-functional teams.
