About the role

As a Senior Electronics Engineer at MKS, you will design, develop, test, and support electronic systems and subsystems throughout the product lifecycle. You will focus on creating schematics, performing board bring-up and validation, and developing embedded firmware.

What you'll do

• Design, develop, and support electronic hardware for new and existing products throughout the product lifecycle.
• Develop, maintain, and troubleshoot embedded firmware for microcontroller-based systems.
• Perform board bring-up, hardware verification, debugging, and root-cause analysis using laboratory test and measurement equipment.
• Collaborate with cross-functional and global engineering teams to develop robust, reliable, and manufacturable product solutions.
• Participate in customer-facing technical discussions, workshops, and escalation activities.

What you'll need

• Strong foundation in electronic circuit design, including schematic capture, component selection, and debugging of digital and mixed-signal circuits.
• Experience with PCB development and familiarity with PCB fabrication, assembly, and test processes, including Design for Manufacturability (DfM), Design for Reliability (DfR), and Design for Testability (DfT).
• Experience developing embedded firmware for microcontroller-based systems using C/C++.
• Hands-on experience with board bring-up, hardware validation, and laboratory debug tools such as oscilloscopes, logic analyzers, and related instrumentation.
• Experience using Python or other scripting languages for engineering automation, data analysis, or test development.
• 5+ years of relevant electronics engineering experience with a Bachelor's Degree or 3+ years with a Master's Degree.

Nice to have

• Experience with PCB design tools such as Altium Designer.
• Experience with ARM, STM32, PIC, AVR, MSP430, or similar microcontroller platforms.
• Familiarity with common communication interfaces such as SPI, I2C, UART, USB, and Ethernet.
• Experience with automated test systems, engineering software tools, or laboratory data analysis.
• Exposure to FPGA technologies.
