Key Responsibilities

• Software Development
• Implement embedded software modules using C/C++ or ADA per DO-178B/C objectives (Level B/C).
• Develop real-time applications running on RTOS platforms (VxWorks, QNX, Integrity, RTLinux).
• Design, code, and debug low-level drivers, middleware, and communication stacks.
• Prepare and maintain Software Design Descriptions (SDD), Low-Level Requirements (LLR), and interface documents.
• Follow strict coding standards (MISRA C/C++, ADA , static analysis, peer reviews).
• Participate in code reviews, configuration management, and continuous integration pipelines.
• Software Integration & Testing
• Support unit, integration, and module-level testing using LDRA / VectorCAST / RTRT / Cantata.
• Conduct requirement-based testing and robustness testing as per verification objectives.
• Assist in test case design, execution, and report preparation (SVP, STR, SVR).
• Participate in HIL (Hardware-in-Loop) and SIL (Software-in-Loop) validation activities.
• Documentation & Process Compliance
• Adhere to DO-178B/C, DoD-2167A, IEEE-12207, and internal development processes (AS9100 / CMMI L3+).
• Maintain complete traceability between requirements, code, and tests using tools such as DOORS or Polarion.
• Ensure configuration control using Git/SVN and participate in internal/external reviews (SDR, CDR, TRR).
• Cross-Functional Collaboration
• Collaborate with System Engineering, Hardware, and QA teams for requirement clarification and system integration.
• Support issue debugging during integration and qualification phases.
• Contribute to continuous improvement in coding practices, test automation, and tool utilization.
