Electronics Hardware Engineer

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, …)
