⚡ Position: Embedded Firmware Engineer - Industrial MCU Systems

🎯 Prerequisites: Low-level firmware development on microcontrollers, C/C++, drivers

📍 Location: Vallès Oriental

📄 Contract: Permanent contract directly with the client

The project

You will join an industrial environment specialized in the development of microcontroller-based electronic systems for critical applications.

Firmware is developed without an operating system, under a deterministic architecture with strict management of timing and latency. These are not simple systems, but complex technological platforms where robustness, stability, and reliability are essential.

The technical focus includes:

  • Deterministic control
  • Direct hardware integration
  • Precise management of interrupts and peripherals
  • High technological demands
  • Zero-defect-oriented culture
  • Products with long life cycles in an industrial environment

You will work closely with hardware, validation, and quality teams, participating from technical definition through to product industrialization.

What you'll do

What you will do

  • Develop firmware for microcontrollers in deterministic architectures
  • Implement low-level drivers: GPIO, timers, ADC/DAC, PWM, UART, SPI, I²C, CAN, DMA
  • Program at the register and peripheral level
  • Manage interrupts and critical timing
  • Implement industrial communication protocols (CAN, Modbus RTU, RS-485...)
  • Participate in the definition of new MCU-based electronic boards
  • Debug and validate using oscilloscope, logic analyzer, and JTAG
  • Ensure system stability, controlled latency, and predictable behavior
  • Contribute to a robust, maintainable, and scalable firmware architecture

What we're looking for

What we are looking for

  • Education in Electronic Engineering, Electrical Engineering, Computer Science, or similar
  • At least 5 years of experience in embedded firmware
  • Strong command of C applied to microcontrollers (C++ valued if embedded)
  • Experience developing firmware without an operating system
  • Strong understanding of interrupts, timing, memory, and register-level programming
  • Solid knowledge of analog and digital electronics
  • Experience with complex technological systems requiring high reliability
  • Ability to work closely with hardware
  • Intermediate technical English
  • Experience in an industrial environment
  • Good documentation practices
  • Test automation (Python, RobotFramework)
  • Knowledge of continuous integration tools

What you'll get

What is offered

  • Complete development of proprietary industrial products
  • Demanding and structured technological environment
  • Complex systems with a high level of technical responsibility
  • Quality and continuous improvement culture
  • Direct collaboration with hardware and multidisciplinary teams
  • Stability and long-term vision
