We are looking for an experienced Senior Hardware Engineer / PCB Designer who will be responsible for the full hardware development lifecycle of IoT devices — from concept and schematic design to PCB layout and testing.
This role requires strong electronics expertise, hands-on PCB design skills, and the ability to take ownership of technical decisions while working closely with a cross-functional team.
Responsibilities:
- Design electrical schematics for IoT devices.
- Develop PCB layouts (from 2-layer to multilayer boards, including high-speed and RF designs).
- Select electronic components considering availability, cost, and project requirements.
- Design and optimize power management solutions, including battery-powered systems and low-power modes.
- Integrate microcontrollers and peripherals (STM32, ESP32, Nordic, NXP, TI, and others).
- Build, solder, and bring up hardware prototypes; perform initial testing and debugging.
- Debug and validate hardware using oscilloscopes, logic analyzers, multimeters, and other lab equipment.
- Prepare manufacturing files (Gerber, BOM, Pick & Place) and collaborate with PCB manufacturers to ensure quality and specification compliance.
- Maintain complete technical documentation for manufacturing, certification, and future support.
- Analyze technical documentation, datasheets, and specifications to make well-grounded engineering decisions.
Requirements:
- 4+ years of commercial experience in hardware development and PCB design.
- Proven experience in schematic design and development of digital and analog circuits.
- Confident use of Altium Designer / KiCad / Eagle for PCB design.
- Solid understanding of high-speed signal integrity, EMI/EMC protection, and shielding principles.
- Hands-on experience with wireless technologies: Wi-Fi, Bluetooth, LoRa, Zigbee, NB-IoT, 4G/5G, RFID, UWB.
- Experience integrating various sensors (temperature, humidity, vibration, acceleration, etc.).
- Experience with low-voltage power systems (DC-DC converters, LDOs, batteries, power-efficient architectures).
- Practical hardware debugging skills using oscilloscopes, logic analyzers, and other measurement tools.
- Ability to work in a fast-paced environment, collaborate with teammates, and take responsibility for technical solutions.
- Basic knowledge of embedded programming (C/C++ for microcontrollers will be a plus).
Nice to have:
- Experience with LTspice, PSpice, MATLAB, or similar simulation tools.
- Understanding of IoT device certification and compliance requirements in different regions (EU, USA, China).
- Experience with MEMS and advanced sensor technologies.
- Practical knowledge of PCB manufacturing and interaction with fabrication and assembly vendors.
Our Benefits: - Professional growth: Individual development plan, mentorship, reimbursement for professional certifications and English lessons, access to professional courses in Corporate Learning Management System.
- Community: Tech community and knowledge-sharing events, English speaking club, corporate library and book club, volunteering and charity initiatives.
- Wellbeing: Medical insurance, regular medical check-ups, sport reimbursement, paid vacation and sick leave, mental health support, and events.
- Work environment: Fully-equipped offices, top-notch equipment, flexible work format, activities both in-office and online, Y-bucks, and access to the Yalantis store.
