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.\nExperience 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.\nKey Responsibilities\nDesign 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.\nSelect components based on performance, cost, availability, reliability, and lifecycle risk.\nDrive RED, CE certification, and EMC compliance for electronic subsystems, including test preparation, lab coordination, and issue resolution. Work with test houses and notified bodies.\nTechnical follow-up of Asian suppliers doing outsourced development projects\nValidate hardware through bench testing, system integration, environmental and reliability testing, and field trials to confirm compliance with design specs.\nBring up prototypes, troubleshoot hardware issues, perform root cause analysis, and implement corrective actions.\nCoordinate with EMS partners and component suppliers on manufacturing qualification and transfer.\nParticipate in design reviews and provide technical input on system architecture, risk assessment, and design trade-offs.\nMaintain schematics, test reports, BOMs, qualification records, and engineering change documentation.\nAnalyze test results and recommend design improvements for performance, manufacturability, and reliability.\nWork with the firmware team on embedded hardware and software co-design and integration.\nImplementing new powertrain systems onto ebikes (Battery management systems, BLDC motor, motor controller, torque sensors, …)\nRequirements\nMust haves\nBachelor’s or Master’s degree in Electrical Engineering, Electronic Engineering, or a related field.\nAt least 5-7 years of experience in electronic hardware design and development, ideally in automotive or e-mobility.\nStrong understanding of analog and digital circuit design principles.\nStrong, in-depth understanding of BLDC motors and control systems\nUnderstanding of the BMSs and battery protection mechanisms\nExperience with radio technologies such as BLE 4.0, EDGE, LTE-M, GNSS, Qi 1.2.4/Qi2.0\nExperience creating schematics and PCB LGA/BGA layouts\nExperience in antenna placement within complex 3D environments\nStrong proficiency with Altium Designer\nHands-on experience and willingness to manually assemble PCBs with solder paste and a reflow oven\nHands-on experience with lab equipment: Vector Network Analyser, Oscilloscope, and logic analyser\nExperience with RED, EMC, and CE testing and certification processes.\nStrong hardware debugging, troubleshooting, and validation and verification skills.\nAble to manage multiple tasks, working both independently and within a multidisciplinary team.\nNice to Have\nExperience with Nordic chips, and/or uBlox modules\nExperience with CANopen is a plus\nExperience with dynamic powertrain control systems\nExperience with battery-powered low-power systems\nFamiliarity with EMS and manufacturing partner qualification processes.\nExperience with C++ and ZephyrOS\nBenefits\nBenefits\n30 days holidays (20 legal + 10 extra legal at prorata ofc)\n200 eur net allowance (office set up/internet)\n10 eur/net per working day meal allowance (+/- 200 eur/month if 20 days worked)\nExtra hospitalization insurance (Alan)\nA Cowboy
