  for embedded devices.
• Utilize and integrate various hardware components and test tools to accurately simulate real-world conditions and validate device behavior.

Connectivity Protocol Validation:

• Conduct thorough testing of various

  connectivity protocols

  including

  Ethernet, RS485, RS232, and CAN bus

  , ensuring reliable data transfer and seamless device integration.

Test Automation & Scripting:

• Demonstrate hands-on experience with

  Python scripting

  for developing automated test cases, utilities, and robust test frameworks.
• Apply a strong understanding of

  Object-Oriented Programming (OOPs) concepts in Python

  for building scalable and maintainable automation solutions.
• Possess hands-on experience in designing and developing

  test automation frameworks

  using tools like

  Robot Framework, Pytest

  , or similar (e.g., Pybot).
• Develop and maintain automated test scripts for continuous integration and efficient regression testing.

Test Documentation & Management:

• Create detailed test plans, comprehensive test cases, and insightful test reports.
• Utilize and maintain test artifacts within version control systems like

  GIT

  .
• Report and track defects effectively using bug tracking tools such as

  JIRA

  or similar.

Tooling & Simulators:

• Be proficient in using in-house developed tools and simulators for effective firmware testing and debugging.
• Identify opportunities for new tool development or enhancements to significantly improve testing efficiency.

Collaboration & Communication:

• Work effectively within a cross-functional team, including hardware, firmware, and software engineers.
• Possess strong communication skills to articulate technical issues, test results, and recommendations clearly and concisely.

Required Skills & Qualifications:

• Experience:

  Strong experience (typically 5+ years) in

  Firmware testing

  for Industrial Embedded Devices, Gateways, and Edge Controllers.

• Industrial Protocols (Mandatory):

  Proven experience in Protocol Testing, especially with

  Modbus TCP/RTU

  . Knowledge of BACnet and OPC-UA is a significant plus.

• Connectivity Protocols:

  Hands-on experience with testing Ethernet, RS485, RS232, and CAN connectivity.

• Hardware-in-the-Loop (HIL):

  Direct experience with HIL testing setups and methodologies.

• Programming & Automation:

  Proficiency in

  Python scripting language

  , including Object-Oriented Programming (OOPs) concepts. Hands-on experience with Test Automation Framework design and development (Robot Framework, Pytest, or similar).

• Test Management:

  Experience in Test Case writing and Test Plan creation. Working knowledge of GIT or other software configuration management tools. Familiarity with JIRA or similar bug tracking tools.

• Problem-Solving:

  Strong analytical and problem-solving skills to troubleshoot complex firmware and hardware interactions.

• Communication:

  Excellent written and verbal communication skills.

• Education:

  Bachelor's or Master's degree in Electrical Engineering, Electronics Engineering, Computer Science, or a related field.
