Hardware (Electronics) Engineer

We are looking for a practical, hands-on Electronics Engineer to join our growing hardware team in Barcelona for systems that require robust, high-performance embedded electronics - built from scratch and validated through deep iteration.

This is a lab-heavy, tool-in-hand role for someone who enjoys not just designing boards but getting them to work in the real world - probing signals, fixing layout issues, replacing components under a microscope, and rapidly iterating designs.

• Own PCB designs from schematic to layout to bench validation for real-time embedded control systems (MCUs, drivers, sensors)

• Build, rework, and debug prototype boards - including soldering, hot-air reflow, and patch wiring for last-minute changes

• Systematically investigate and solve board-level issues using oscilloscopes, multimeters, logic analyzers, and signal generators

• Collaborate with firmware and mechanical teams to bring up systems and integrate electronics into functional prototypes

• Prepare BOMs, layout notes, and clearly documented test reports

• Validate electronics in the context of complex systems - identify electrical issues, fix them, and document learnings

• Support in-house prototype assembly and iterate quickly between board versions

• Provide design-for-debug input and improve testability of production boards

• A degree in Electrical/Electronics Engineering or equivalent practical experience

• 2-4 years of industry experience working on embedded hardware designs

• Proficiency with schematic capture and PCB layout tools (Eagle preferred)

• Comfort and confidence with hands-on rework: soldering 0603 passives, reflowing fine-pitch ICs, or patching traces on a prototype board

• Experience testing microcontroller-based systems and common interfaces like SPI, I2C, UART, USB

• Ability to identify and fix signal integrity or power-related issues using test equipment

• Basic understanding of embedded firmware flows - able to flash and interact with firmware during bring-up

• A willingness to iterate, debug, and get hardware into a working, testable state

• Experience with ARM Cortex microcontrollers

• Knowledge of EMI/EMC practices, protection circuitry, or certification prep

• Experience working on motor control, sensor integration, or Ethernet hardware

• Exposure to test automation or scripting for board validation

You Will Fit Great If:

• You are a natural problem solver and thinker - comfortable probing unknown circuits and figuring things out

• You get satisfaction from making hardware work - and even more when you fix something that didn’t

• You thrive in environments where prototypes evolve weekly and no two board spins are alike

• You believe hardware development is not done until it works on the bench and in the proto not just in CAD

• Competitive salary
• Excellent location near Barcelona, in a very inspiring office
• Professional development and career advancement opportunities in a fast growing new company with unique technology
• A truly open-minded and supportive work environment with a high level of employee empowerment
• Flexible working hours
• Free snacks, fruits, coffee and tea
