We are looking for an experienced Hardware Engineer / IoT Hardware Consultant who will be involved on an ad-hoc basis to support specific hardware-related requests, including presales, discovery, technical estimation, and solution validation when needed.

This is a consulting cooperation format rather than a full-time dedicated role. The specialist will be engaged depending on project needs to provide hardware expertise, review technical approaches, assess feasibility, and help shape reliable IoT hardware solutions.

Responsibilities:

• Support presales and discovery activities by providing hardware expertise, technical input, and solution validation.
• Review client requirements and help define feasible hardware architecture and implementation approaches.
• Support effort estimation, technical risk assessment, and preparation of hardware-related recommendations for potential projects.
• Develop electrical schematics for IoT devices.
• Design printed circuit boards, from 2-layer to multilayer, including high-speed and RF boards.
• Select electronic components considering availability, cost, reliability, and project requirements.
• Optimize power consumption, work with battery-powered solutions, and implement low-power modes.
• Integrate microcontrollers such as STM32, ESP32, Nordic, NXP, TI, and other hardware components.
• Assemble and test initial board prototypes and debug schematics.
• Use oscilloscopes, logic analyzers, multimeters, and other tools to validate device performance.
• Prepare production files, including Gerber, BOM, and Pick & Place files.
• Support communication with PCB manufacturers and provide input during manufacturing preparation.
• Maintain technical documentation for manufacturing and product lifecycle support.

Requirements:

• Experience in schematic design and development of digital and analog circuits.
• Strong PCB design skills, including experience with 2-layer and multilayer boards.
• Understanding of high-speed signal design, EMI/EMC considerations, and shielding techniques.
• Experience with wireless technologies such as Wi-Fi, Bluetooth, LoRa, Zigbee, NB-IoT, 4G/5G, RFID, or UWB.
• Experience integrating sensors, such as temperature, humidity, vibration, acceleration, or similar.
• Experience with low-voltage power systems, including DC-DC converters, LDOs, batteries, and power-saving techniques.
• Hands-on debugging skills using oscilloscopes, multimeters, logic analyzers, and other lab equipment.
• Ability to analyze client requirements, identify technical risks, and propose feasible hardware solutions.
• Basic knowledge of embedded programming, especially C/C++ for microcontrollers, would be a plus.
• Upper-Intermediate level of English or higher.

Nice to have:

• Experience with simulation tools such as LTspice, PSpice, MATLAB, or similar.
• Familiarity with IoT device certification requirements across different regions, including the EU, USA, and China.
• Experience with MEMS and sensor technologies.
• Understanding of compliance and certification standards.
• Previous experience participating in presales, discovery, technical consulting, or estimation activities.
