Senior Embeeded System Engineer

Decskill; Porto; Híbrido; EUR 55 000 - 85 000; Tempo integral

Resumo da oferta

Decskill, an IT consulting company with over 10 years of consolidated experience, seeks a Senior Embedded System Engineer for a project with a hybrid working model in Porto, Portugal.

You will migrate from ST10F269 to Infineon XC228xH, port bare-metal C/Assembly, review hardware schematics, and develop drivers for CAN, RS232, SPI, and I²C, while integrating PC104 interfaces and CPLDs.

Qualificações

• 5+ years of senior-level electronic design and embedded systems development.
• Expert-level proficiency in C and Assembly for bare-metal embedded applications, no RTOS.
• Extensive hands-on experience with 16/32-bit microcontrollers; ST10 and Infineon XC2000 preferred.
• Strong digital logic, bus interfacing (PC104), and memory interfaces (SRAM/Flash).
• In-depth knowledge of implementing CAN and RS232 at firmware and hardware levels.
• Experience in schematic capture and reviewing complex multi-layer PCB layouts.

Responsabilidades

• Migrate from ST10F269 to Infineon XC228xH platform.
• Port firmware to the new microcontroller architecture in C/Assembly (bare-metal).
• Analyze and redesign hardware schematics for the new MCU integration.
• Analyze and validate mixed-signal circuits including analog inputs and power circuits.
• Develop and debug bare-metal drivers for MCU peripherals (ADC, timers, PWM, CAN, UART, SPI, I2C).
• Ensure correct functionality of interfaces like PC104 bus and CPLD (Lattice M4A5).

Descrição da oferta de emprego

We are growing. And we are looking for talented people.

At Decskill, we believe that technological excellence is driven by human talent.

We are an IT consulting company with more than 10 years of consolidated experience in the market, focused on building long-term relationships with both our clients and our people. Today, we are a community of over 800 professionals, working from Lisbon, Porto, and Madrid, contributing to impactful technology initiatives.

As part of the Astek Group, we combine a strong local culture with a global presence, being active in around 23 countries across 4 continents. This allows us to offer an international context, diverse challenges, and long-term career opportunities, while staying close to our teams.

We would like to meet a Senior Embeeded System Engineer for a project with a hybrid working model:

Responsibilities:

• migration from the legacy STMicroelectronics ST10F269 microcontroller to the new Infineon XC228xH platform.
• Firmware Porting: Port the existing bare-metal codebase, written in C and Assembly, to the new microcontroller architecture. This includes adapting low-level drivers and ensuring functional parity.
• Hardware Redesign and Review: Conduct a thorough analysis of the new schematics that will be redesigned by other (printed circuit board that will accommodate the new microcontroller and any necessary supporting components).
• Circuit Design Analysis: Analyse and validate the system's mixed-signal circuits. This includes:
• Analog input stages with operational amplifiers (TL084) and analog switches.
• Power supply circuits, including DC-DC converters (LM2599) and SMPS controllers (UC2844).
• Interfaces for PWM outputs and various digital I/Os.
• Peripheral Integration: Develop and debug bare-metal drivers for all microcontroller peripherals, including ADCs, timers, PWM units, CAN, UART (RS232), SPI, and I²C.
• Interface Management: Ensure the correct functionality of external interfaces, including the PC104 bus and a Lattice M4A5 CPLD.

Requirements:

• Experience: 5+ years of professional experience in senior-level electronic design and embedded systems development.
• Programming: Expert-level proficiency in C and Assembly for bare-metal embedded applications. You must be comfortable working without an RTOS.
• Microcontrollers: Extensive hands-on experience with 16/32-bit microcontrollers. Direct experience with the STMicroelectronics ST10 family (like the ST10F269) and the Infineon XC2000 family (like the XC228xH) is highly preferred.
• Digital Electronics: Strong understanding of digital logic, bus interfacing (specifically PC104) , and memory interfaces (SRAM, Flash).
• Communication Protocols: In-depth, practical knowledge of implementing and debugging communication interfaces, particularly CAN and RS232, at both the firmware and hardware levels.
• Hardware Design Tools: Proficiency in schematic capture and experience reviewing complex, multi-layer PCB layouts.

Find with us the right opportunity to grow!

What you can expect from us:

• Long-term projects with national and international context
• Opportunities to grow technically and professionally
• A people-first culture, focused on transparency and trust
• Teams that value ownership, collaboration and stability

Your next challenge might start here.

At Decskill, we are committed to equal opportunities and non-discrimination. We promote a culture of diversity and inclusion, where recruitment and career progression are based solely on talent, regardless of age, gender, ethnicity, race, nationality, or any other form of discrimination incompatible with human dignity.
