OverviewWe 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. As part of the Astek Group, we combine a strong local culture with a global presence, 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 Embedded System Engineer for a project with a hybrid working model. ResponsibilitiesMigration 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, adapting low-level drivers and ensuring functional parity. Hardware redesign and review: Conduct a thorough analysis of the new schematics designed by others to accommodate the new microcontroller and supporting components. Circuit design analysis: Analyze and validate the system's mixed-signal circuits, including analog input stages with operational amplifiers (TL084) and analog switches, power supply circuits with DC-DC converters (LM2599) and SMPS controllers (UC2844), and interfaces for PWM outputs and various digital I/Os. Peripheral integration: Develop and debug bare-metal drivers for microcontroller peripherals, including ADCs, timers, PWM units, CAN, UART (RS232), SPI, and I2C. Interface management: Ensure correct functionality of external interfaces, including the PC104 bus and a Lattice M4A5 CPLD. RequirementsExperience: 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; must be comfortable working without an RTOS. Microcontrollers: Extensive hands-on experience with 16/32-bit microcontrollers; direct experience with STMicroelectronics ST10 family (e.g., ST10F269) and Infineon XC2000 family (e.g., XC228xH) is highly preferred. Digital Electronics: Strong understanding of digital logic, bus interfacing (PC104), and memory interfaces (SRAM, Flash). Communication Protocols: Knowledge of implementing and debugging CAN and RS232 interfaces at both firmware and hardware levels. Hardware Design Tools: Proficiency in schematic capture and experience reviewing complex, multi-layer PCB layouts. What you can expect from us: Long-term projects with national and international context (if applicable). Opportunities to grow technically and professionally. A people-first culture focused on transparency and trust; teams that value ownership, collaboration, and stability. Join us. Send your CV in English with reference "DA / EMB". 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.
