Experience:

4–6 years

Job Overview

We are looking for a highly skilled Hardware Engineer with deep expertise in low-power electronics, RF design, and embedded hardware systems. This role involves end-to-end hardware development—from schematic and PCB design to prototyping, testing, and production—while working closely with firmware engineers to build optimized, high-performance wireless devices.

Key Responsibilities

  • Design and develop low-power, battery-operated embedded hardware systems
  • Lead RF and antenna design for wireless systems including:Bluetooth Low Energy (BLE) Wi-Fi Other RF protocols (as applicable)
  • Design multi-layer PCBs (minimum 4 layers) with focus on:Controlled impedance routing RF layout best practices Signal integrity and noise minimization Antenna matching and tuning
  • Create and maintain:Schematics PCB layouts Bill of Materials (BOM) with cost and availability optimization
  • Rapidly prototype hardware systems integrating:Accelerometers Gyroscopes Microphones Cameras NOR Flash and other memory Additional sensors and peripherals
  • Perform hardware bring-up, validation, and debugging
  • Collaborate closely with firmware engineers to:Optimize power consumption Ensure reliable sensor interfacing and data acquisition Improve wireless performance (range, throughput, stability)
  • Test and validate hardware and firmware performance, including:Power profiling RF performance (range, packet loss, throughput) Signal integrity
  • Generate detailed test reports with actionable insights
  • Develop and maintain mechanical test jigs and fixtures for:Device validation Repeatable testing Data collection setups
  • Coordinate with EMS (Electronics Manufacturing Services) partners in China for:Prototype builds DFM (Design for Manufacturing) feedback Production scaling and issue resolution

Required Skills & Qualifications

  • Strong experience in low-power hardware design for battery-operated devices
  • Proven expertise in RF and antenna design, including:Antenna selection, matching, and tuning RF measurement tools (VNA, spectrum analyzer, etc.)
  • Hands-on experience with 4+ layer PCB design tools (e.g., Altium, KiCad, OrCAD)
  • Deep understanding of:Controlled impedance and stack-up design EMI/EMC considerations Signal and power integrity
  • Experience in BOM management with cost and supply-chain awareness
  • Strong experience in schematic design and hardware architecture
  • Experience with sensor integration and mixed-signal systems
  • Practical experience in hardware debugging and validation
  • Ability to interpret and collaborate on firmware-hardware interfaces (SPI, I2C, UART, etc.)
  • Familiarity with DFM/DFA best practices

Preferred Qualifications

  • Experience working on BLE/Wi-Fi-based embedded products
  • Familiarity with Nordic Semiconductor (nRF) platforms or similar SoCs
  • Knowledge of power optimization techniques at both hardware and system levels
  • Basic understanding of firmware workflows and constraints
  • Experience with mechanical design concepts (for test fixtures or enclosures)
  • Exposure to camera interfaces (e.g., MIPI CSI) and audio front-end design
  • Experience with compliance testing (CE, FCC, etc.)
  • Experience in wearable or compact IoT device design
  • Experience in mass production and scaling hardware

Soft Skills

  • Strong cross-functional collaboration skills (especially with firmware teams)
  • Detail-oriented with a focus on design robustness and reliability
  • Strong problem-solving and debugging mindset
  • Effective communication and documentation skills

Cross-Functional Collaboration

  • Work closely with firmware engineers to co-design power-efficient systems
  • Ensure hardware supports high-frequency data acquisition and streaming
  • Align on RF performance tuning and BLE/Wi-Fi optimization
  • Enable efficient sensor data pipelines and storage systems
  • Collaborate with Motion Algorithm Engineers to:Optimize algorithms for embedded deployment Ensure real-time performance and efficiency
  • Jointly debug system-level issues across hardware and firmware

Key Priority Requirements

  1. Expertise in Low power electronics and battery powered devices
  2. Expertise in Antenna / RF Design for BLE, WiFi and other wireless systems
  3. Expertise in PCB design for 4 layers or more
  4. Expertise in rapid prototype development

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
