About

Hardware / Electrical Engineer with 6+ years of hands-on experience in the design and integration of complex electrical systems. Strong background in PCB development and wiring harness systems, working across the full product lifecycle, from concept and design to prototyping, testing, manufacturing, and field integration. Throughout my career, I have worked on end-to-end PCB projects, including schematic design, component selection, BOM management, prototype bring-up, validation, system-level integration, and network-based validation activities. Alongside this, I have expanded my scope toward system-level electrical architecture and wiring harness design, taking ownership of electrical systems while maintaining a strong foundation in electronics and PCB engineering. In addition to core hardware activities, I have experience in electronics library development and regularly collaborate with mechanical engineering, manufacturing, suppliers, and software teams. This cross-functional exposure allows me to contribute effectively to system integration, validation, and troubleshooting activities in complex R&D environments. I hold a degree in Computer Engineering, with a solid foundation in electronics, embedded systems, and engineering project management. While my background includes low-level software exposure, my professional focus is on hardware and electrical engineering for real-world, complex systems. Open to international opportunities, including relocation. PCB Design | Wiring and Harness | Altium Designer | Solidworks Electrical

Experience

  • Hardware & Electrical Engineer at J.Assy
    Aug 2022 - Present · 4 yrs

    J.Assy – Brazil’s leading planting technology company, powering precision agriculture systems. Responsible for electrical and hardware engineering activities across multiple phases of an agricultural equipment R&D program, with hands-on involvement in PCB development, electronics library management, system-level wiring harness design, and validation. Worked on end-to-end PCB development using Altium Designer, including schematic design, component selection, BOM management, prototype bring-up, validation, system integration, and network-based testing. Developed and maintained electronics libraries for schematic symbols and PCB footprints, following internal quality guidelines and industry standards to ensure scalable and reliable hardware development. Owned the electrical architecture and full wiring harness design for large-scale industrial equipment, including electrical diagrams, connector and wire selection, harness routing, manufacturing documentation, assembly support, testing, and system integration. Coordinated and reviewed electrical engineering activities by managing tasks in Jira and supporting multiple contributors to ensure alignment with timelines and technical requirements. Worked closely with mechanical teams to integrate 3D wiring harness routing into equipment design, addressing spatial constraints, mounting points, and interactions with mechanical and hydraulic subsystems. Performed system-level validation of CAN-based networks using CANoe with VN1630 hardware, developing test panels, CAPL scripts, integrating DBC files, and executing test setups with software teams. Participated in validation and field testing, identifying electrical issues, conducting root cause analysis, and proposing design improvements to increase robustness and reliability. Contributed to early-stage industrialization planning, with exposure to manufacturing processes and assembly activities.

  • Hardware / Electronics Engineer at HEXBits Tecnologia
    Jun 2019 - Aug 2022 · 3 yrs 3 mos

    Worked on the development of electronic hardware for telecommunications equipment, progressing from internship to engineering roles with increasing responsibility across PCB design, manufacturing support, testing, and product improvement. Designed and developed through-hole PCBs for telecommunications enclosures, including schematic capture, component selection, BOM management, PCB layout using Eagle CAD, and support through assembly and validation phases. Worked closely with in-house manufacturing, supporting PCB assembly, soldering processes, quality inspection, and functional testing to ensure product reliability and compliance with design requirements. Performed board-level and stress testing, identifying electrical and thermal issues, analyzing failures, and implementing hardware redesigns to improve robustness and long-term performance. Contributed to embedded software development in C/C++ for microcontroller-based systems, including ESP32 and Arduino platforms, supporting features such as temperature monitoring, fan control, and alarm systems. Participated in the development of industrial electronic systems for telecommunications infrastructure, including limited involvement in a PLC hardware development project, gaining exposure to system-level design considerations.
