Senior Electronics Hardware Engineer – E-Bike Connectivity

About the role

Cowboy is looking for a Senior Electronics Hardware Engineer to lead the design, validation and industrialization of the electronic subsystems powering its e-bikes, with a focus on connectivity: communication modules (BLE, GNSS, EDGE, LTE-M, Qi) and sensor systems. The engineer owns hardware design end-to-end, from schematic through certification and productization, working closely with firmware, mechanical and supply chain teams.

Key responsibilities

• Design analog, digital and mixed-signal circuits for communication modules and sensor systems, including schematics, PCB and antenna layout and design reviews.
• Select components based on performance, cost, availability, reliability and lifecycle risk.
• Drive RED, CE certification and EMC compliance, including test preparation, lab coordination and work with test houses and notified bodies.
• Follow up Asian suppliers doing outsourced development projects.
• Validate hardware through bench testing, system integration, environmental and reliability testing and field trials.
• Bring up prototypes, troubleshoot hardware issues, run root cause analysis and coordinate EMS partners and suppliers on manufacturing qualification.
• Participate in design reviews, maintain schematics, test reports, BOMs, qualification records and engineering change documentation, and analyze test results to recommend improvements.
• Work with the firmware team on embedded hardware and software co-design, and help implement new powertrain systems (BMS, BLDC motor, motor controller, torque sensors).

Required profile

• Bachelor's or Master's degree in Electrical or Electronic Engineering or a related field.
• At least 5-7 years of experience in electronic hardware design, ideally in automotive or e-mobility.
• Strong understanding of analog and digital circuit design, and of BLDC motors and control systems.
• Understanding of BMS and battery protection mechanisms.
• Experience with RED, EMC and CE testing and certification.
• Able to manage multiple tasks, independently and in a multidisciplinary team.

Required skills

• Schematics and PCB LGA/BGA layout; antenna placement in complex 3D environments.
• Altium Designer.
• Manual PCB assembly with solder paste and a reflow oven.
• Lab equipment: Vector Network Analyzer, oscilloscope and logic analyser.
• Nice to have: Nordic chips, uBlox modules, CANopen, dynamic powertrain control, battery-powered low-power systems, EMS qualification, C++ and ZephyrOS.

What we offer

• 30 days of holiday (20 legal plus 10 extra at pro-rata).
• 200 EUR net allowance for office setup and internet, plus meal allowance of 10 EUR per working day.
• Extra hospitalization insurance and a Cowboy bike.
• Hybrid working environment and a cafeteria plan to optimize the 13th-month salary.
