Electronic Engineer - Research & Design (Mid Level)

Job Summary:

We are looking for a Mid-Level Electronic Design Engineer with 2–5 years of experience to design, develop, and validate electronic hardware for our products. You will own PCB and circuit design from concept through production, working closely with mechanical, firmware, and manufacturing teams to deliver reliable, manufacturable, and cost-effective electronics.

Key Responsibilities:

Design & Development:

• Design analog, digital, and mixed-signal circuits based on product requirements
• Select components (microcontrollers, sensors, power management ICs, connectors, passives) based on performance, cost, availability, and lifecycle
• Create schematics and PCB layouts using ECAD tools (Altium Designer, KiCad, Eagle, or similar)
• Perform power budget calculations, signal integrity analysis, and EMI/EMC considerations at the design stage
• Design power supply circuits (regulators, battery management, charging circuits) as required by the product
• Develop and maintain schematic libraries, footprints, and component databases

Prototyping & Validation:

• Build and bring up prototype boards; debug hardware issues using lab equipment (oscilloscopes, logic analyzers, multimeters, spectrum analyzers)
• Plan and execute functional testing, stress testing, and environmental testing (temperature, humidity, vibration) on hardware
• Coordinate and support EMI/EMC pre-compliance and compliance testing (FCC, CE, etc.)
• Analyze test failures and iterate on circuit/layout design; document root causes and fixes

Cross-Functional Integration:

• Collaborate with mechanical engineering on PCB form factor, connector placement, mounting, and thermal considerations
• Work closely with firmware engineers to define hardware interfaces, communication protocols, and register-level requirements
• Support firmware bring-up by providing hardware documentation, schematics, and debug access (test points, JTAG/SWD headers)
• Coordinate with PCB fabricators and assembly houses on DFM/DFA reviews, panelization, and assembly requirements

Production Support & Documentation:

• Prepare and maintain technical documentation: schematics, BOMs, assembly drawings, and test procedures
• Manage engineering change orders (ECO) and engineering change notices (ECN) through the product lifecycle
• Support production ramp-up, troubleshoot hardware issues on the line, and drive root-cause analysis for field returns/failures
• Contribute to cost-reduction initiatives (component substitution, design simplification) post-launch

Required Skills & Qualifications:

• Bachelor's degree in Electronics/Electrical Engineering or related field
• 2–5 years of hands-on experience in electronic hardware design, preferably in consumer electronics, IoT, or embedded hardware products
• Strong proficiency in schematic capture and PCB layout tools (Altium Designer, KiCad, or equivalent)
• Solid understanding of analog and digital circuit design fundamentals
• Experience with microcontroller-based designs and common communication interfaces (I2C, SPI, UART, USB, CAN)
• Practical experience with power supply design (linear/switching regulators, battery charging circuits)
• Hands-on experience using lab equipment for hardware debug and validation
• Working knowledge of EMI/EMC design principles and PCB layout best practices for signal integrity
• Strong analytical and problem-solving skills with meticulous attention to detail
• Effective communicator, comfortable working cross-functionally with mechanical, firmware, and supply chain teams

Preferred/Bonus Skills:

• Experience with wireless communication modules (Wi-Fi, BLE, LoRa, cellular)
• Familiarity with high-speed digital design or RF layout
• Experience with battery-powered/low-power design techniques
• Exposure to regulatory compliance testing (FCC, CE, IC) and certification processes
• Experience with PLM/PDM tools for design version control
• Track record of taking at least one product through full mass production

What We Offer:

• Opportunity to own end-to-end electronic hardware design for real, shipping products
• Close collaboration with a multidisciplinary hardware team
