Hardware Design Engineer

Senior-level Electrical Engineer / Lead

Senior-level Electrical & Electronics Design Lead

The ideal candidate will have extensive experience in analog and digital design, power electronics, including off-line switching power supplies, battery chargers, and regulatory compliance for UL and FCC standards. This role entails end-to-end system design, from architecture, design, component selection to schematic, BOM and PCB layout creation, prototyping, validation and full system integration.

Key Responsibilities:

Responsibilities:

• Lead Mixed-Signal design projects, including microcontrollers and microprocessors, AC-DC and DC-DC power converters and communication interfaces
• Design wired and wireless networking interfaces such as Ethernet, RS-232/485, TCP/IP, BLE, LoRaWAN, Zigbee, Sub-1GHz
• Design high-efficiency, fan-less off-line switching power supplies (QR/LLC topology) with universal input (85264VAC)
• Design and deploy passive and active Power Factor Correction (PFC) techniques in SMPS
• Design magnetics and passive thermal solutions to meet UL864 and FCC Part 15 Class A standards
• Design battery charging, monitoring and safety systems for Sealed Lead-Acid and Lithium-Ion battery packs
• Analyze power budgeting to derive the right specs for component selection
• Conduct Stress analysis and Worst-Case Circuit Analysis (WCCA) to assess design reliability
• Conduct Reliability analysis to derive MTBF and MTTF at product level
• Conduct DFMEA and FMEDA to assess impact of component failures and devise schemes to safely handle failures
• Design self-diagnostics techniques to enable fault detection and reporting
• Develop schematics, lead component selection and BOM creation, and manage PCB layouts
• Manage product prototyping and functional validation – board bring-up, EVT, DVT, PVT
• Manage compliance-in-design for UL864 and FCC part 15 requirements
• Plan for and conduct EMC and regulatory testing – Conducted and Radiated Emissions and Immunity, Transients & Surge, Voltage Interruptions, Safety Isolations, and Environmental tests
• Plan for and support in UL864 and other certifications
• Ensure compliance with the defined Product Development lifecycle processes
• Interface with international clients for status reporting, design reviews and project delivery
• Performs all other duties assigned, including team management and process compliance

Qualifications:

• Bachelors or Masters degree in electrical or Electronics Engineering or related field

Preferred Skills:

• Experience with multiple EDA tools, primarily with Altium Designer
• Simulation experience (LTspice, PLECS, or equivalent)
• Prior experience designing Fire Safety or Life-Safety systems
• Independent project management and problem-solving skills
