# Electronics Hardware Engineer

> Cowboy · Brussels, Belgium (Hybrid) · Full-time · Posted 2026-07-13

**Workplace:** hybrid

**Department:** Hardware

## Description

Cowboy is looking for a **Senior Electronics Hardware Engineer** to lead the design, validation, and industrialization of the electronic subsystems that power our e-bikes — with a particular focus on connectivity, from communication modules (BLE, GNSS, EDGE, LTE-M, Qi) to sensor systems. You’ll own hardware design end-to-end, from schematic through certification and productization, working closely with firmware, mechanical, and supply chain teams to bring robust, connected hardware to riders at scale.  
Experience with e-bike powertrains — BLDC motor systems and battery management systems — is a strong plus, as is hands-on experience navigating CE, RED, and other electronics certifications.  
  
**Key Responsibilities**  

-   Design and develop analog, digital, and mixed-signal circuits for Cowboy’s cellular/BLE/GNSS communication modules and sensor systems, including schematics, PCB layout + antenna layout, and design reviews.
-   Select components based on performance, cost, availability, reliability, and lifecycle risk.
-   Drive RED, CE certification, and EMC compliance for electronic subsystems, including test preparation, lab coordination, and issue resolution. Work with test houses and notified bodies.
-   Technical follow-up of Asian suppliers doing outsourced development projects
-   Validate hardware through bench testing, system integration, environmental and reliability testing, and field trials to confirm compliance with design specs.
-   Bring up prototypes, troubleshoot hardware issues, perform root cause analysis, and implement corrective actions.
-   Coordinate with EMS partners and component suppliers on manufacturing qualification and transfer.
-   Participate in design reviews and provide technical input on system architecture, risk assessment, and design trade-offs.
-   Maintain schematics, test reports, BOMs, qualification records, and engineering change documentation.
-   Analyze test results and recommend design improvements for performance, manufacturability, and reliability.
-   Work with the firmware team on embedded hardware and software co-design and integration.
-   Implementing new powertrain systems onto ebikes (Battery management systems, BLDC motor, motor controller, torque sensors, …)

## Requirements

**Must haves**

-   Bachelor’s or Master’s degree in Electrical Engineering, Electronic Engineering, or a related field.
-   At least 5-7 years of experience in electronic hardware design and development, ideally in automotive or e-mobility.
-   Strong understanding of analog and digital circuit design principles.
-   Strong, in-depth understanding of BLDC motors and control systems
-   Understanding of the BMSs and battery protection mechanisms
-   Experience with radio technologies such as BLE 4.0, EDGE, LTE-M, GNSS, Qi 1.2.4/Qi2.0
-   Experience creating schematics and PCB LGA/BGA layouts
-   Experience in antenna placement within complex 3D environments
-   Strong proficiency with Altium Designer
-   Hands-on experience and willingness to manually assemble PCBs with solder paste and a reflow oven
-   Hands-on experience with lab equipment: Vector Network Analyser, Oscilloscope, and logic analyser
-   Experience with RED, EMC, and CE testing and certification processes.
-   Strong hardware debugging, troubleshooting, and validation and verification skills.
-   Able to manage multiple tasks, working both independently and within a multidisciplinary team.

**Nice to Have**

-   Experience with Nordic chips, and/or uBlox modules
-   Experience with CANopen is a plus
-   Experience with dynamic powertrain control systems
-   Experience with battery-powered low-power systems
-   Familiarity with EMS and manufacturing partner qualification processes.
-   Experience with C++ and ZephyrOS
