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
