Embedded Software Integration Testing (SIT) Engineer

Job Summary

We are looking for an Embedded Software Integration Testing (SIT) Engineer with hands-on experience in embedded systems testing. This is a pure testing role and does not involve software design or development. The ideal candidate should have strong knowledge of Embedded C/C++, RTOS/Non-RTOS environments, and software integration testing for safety-critical embedded medical devices.

Key Responsibilities

• Perform Software Integration Testing (SIT) for embedded, microcontroller-based applications.

• Analyze software requirements and design documents to identify test scenarios, test cases, and coverage gaps.

• Develop and execute software integration test plans, test protocols, and regression test suites.

• Understand embedded software developed in C for Non-RTOS and RTOS environments.

• Understand GUI applications developed in C++ for embedded RTOS platforms.

• Perform software code regression analysis to support integration testing activities.

• Identify and configure appropriate hardware and test environments for embedded system validation.

• Participate in requirements, design, and code review meetings by providing testing feedback.

• Validate software functionality for highly safety-critical handheld medical devices.

• Document test results, defects, and test evidence following medical device software development processes.

• Collaborate with development, QA, and cross-functional engineering teams to ensure product quality.

Required Skills

• 1–7 years of hands-on experience in Embedded Software Testing or Software Integration Testing.

• Strong knowledge of Embedded C and C++.

• Experience working with RTOS and Non-RTOS embedded systems.

• Good understanding of SDLC and STLC.

• Experience in requirement analysis, test planning, regression testing, and defect tracking.

• Understanding of microcontroller-based embedded systems.

• Ability to review software design documents and source code from a testing perspective.

• Strong analytical, debugging, and problem-solving skills.

• Excellent communication skills with the ability to clearly explain real-time project experience.

Preferred Skills

• Experience testing medical devices or other safety-critical embedded systems.

• Knowledge of embedded hardware, custom test setups, and integration testing.

• Familiarity with Good Documentation Practices (GDP) and technical documentation.

• Experience participating in requirement, design, and code review meetings.

Note:

• This is a pure Software Integration Testing (SIT) role. Candidates with only embedded development experience and no hands-on testing background will not be considered.

• Candidates must be able to clearly explain their real-time project experience during technical interviews.

• 100% Onsite in Frisco, TX or Alameda, CA.
