# Hardware (Electronics) Engineer

- **Company:** Quantica´s
- **Location:** Barcelona, Spain
- **Contract:** Permanent contract
- **Skills:** Computer-Aided Design, ARM Architecture, Automation of Tests, Software Debugging, Embedded Software, Ethernet, Firmware, Hardware Design, Schematic Capture, Signal Integrity, Universal Asynchronous Receiver/Transmitter, USB, Serial Peripheral Interface, Test Scripts, Pcb Layout
- **Published:** July 21, 2026
- **Apply:** https://www.adzuna.es/contact-us.html

## About the Role

+ 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
What We Value additionally:

 + 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

## Description

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.
What You´ll Be Doing:

 + 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
