About the role
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
