• Implement and optimize 

  embedded communication protocols

  , including industrial field bus protocols (e.g., MODBUS, CAN), network protocols (e.g., USB, TCP/IP, Embedded webservers), and inter-module communication protocols (e.g., I2C, UART, SPI, CAN, DBC).
• Drive 

  cyber security compliant firmware development

  , including system-level/sub-system level threat modelling, ensuring firmware adheres to the latest security standards and best practices, secure boot, secure firmware updates, and data protection.
• Develop and implement 

  Bootloader development

   and reliable firmware upgrade mechanisms.
• Perform hands-on code implementation, debugging, development, code review, and testing of embedded communication systems.
• Participate in subsystem and system-level design verification planning and testing.
• Understand and comply with Quality Management System (QMS), Project Management Plan (PMP), Agile, and Lean development requirements.
• Develop test automation scripting for embedded products and utilize various development tools and emulators.
• Act as a 

  team player

   within an agile development environment, actively participating in code reviews, design discussions, and knowledge sharing.
• Collaborate effectively with 

  global teams

   across different time zones, fostering strong communication and alignment on project goals.
• Deeply 

  understand product requirements, firmware specifications, and communication firmware architecture

   to accurately translate requirements into detailed software designs and implementations.
• Perform comprehensive 

  hardware debugging

   using advanced real-time firmware debugging tools such as J-Trace, logic analyzers, time/performance profiling techniques, Digital Storage Oscilloscopes (

  DSO

  ), 

  PCANView

  , and 

  LabVIEW

  , to diagnose and resolve complex hardware-software interaction issues.
• Contribute to the full product development lifecycle, from concept and architecture definition to deployment and post-release support.
• Mentor junior engineers and contribute to the continuous improvement of engineering processes and best practices.
