Staff Electronics Design Engineer

Responsibilities

• Architect low-voltage and mixed-signal subsystems for SST products, leading trade-offs across performance, reliability, safety, cost, and manufacturability
• Select microcontrollers and key ICs, partner with silicon vendors to evaluate fit, review errata, and influence part selection
• Design and validate control, sensing, and protection circuitry including high-accuracy analog measurement chains, digital I/O, and fault detection
• Design isolated interface circuits like signal isolators, isolated DC-DC, and fiber optics between different voltage domains
• Architect redundancy and fault tolerance into the board to meet single-fault-tolerant and product-lifetime requirements, lead DFMEA and derating reviews
• Implement high-bandwidth and industrial communication interfaces such as Gigabit Ethernet, CAN, and Modbus with attention to signal integrity
• Drive PCB layout in partnership with a dedicated layout engineer, define stackup, impedance, isolation, and routing constraints, review iterations, and execute layout directly when needed
• Own full lifecycle development of PCBAs including specifications, schematics, BOM, prototyping, bring-up, EMI/EMC compliance, and release to production
• Collaborate with firmware engineers on interface and timing definition, and with mechanical engineers on connector placement, thermal, and enclosure integration
• Maintain documentation of requirements, design decisions, and release notes for traceability and compliance

Qualifications

• BS or MS in Electrical Engineering, Computer Engineering, or equivalent industry experience
• 8+ years designing low-voltage and mixed-signal hardware for high-reliability or high-voltage systems, with demonstrated technical leadership across multiple programs
• Proven experience architecting boards from a blank sheet, including MCU selection, partitioning of control, sensing, and protection functions
• Strong analog and mixed-signal design skills with deep knowledge of component selection and derating for harsh environments
• Experience designing isolated interface circuits within reinforced isolation requirements
• Hands-on experience with communication interfaces such as Ethernet, CAN, and Modbus, including signal integrity for higher-speed links
• Proficiency with PCB CAD and simulation tools, preferably Altium Designer, SPICE, or PLECS
• Hands-on PCB layout experience sufficient to specify constraints, review layout critically, and execute layout independently when needed
• Strong board bring-up, debugging, and lab testing skills, with working knowledge of EMI/EMC best practices
• Excellent written and verbal communication in English
• Willingness to travel up to 10%, including internationally

Bonus Qualifications

• Shipped a PCBA in a high-volume product from prototype through sustained production
• Experience with functional safety such as IEC 61508, ISO 13849, or HV design and certification standards such as IEC 61800, UL 508C, IEC 62477
• Experience with high-reliability design for industrial, grid, or similar harsh-environment applications
