• Aware of Security Risk Assessment (SRA) and Threat Modeling for embedded systems following DO-326A /356A.
• Able to define and derive security requirements, implementing secure boot, authentication, encryption, and access control mechanisms.
• Able to Evaluate and mitigate cybersecurity threats across communication interfaces (CAN, SPI, I2C, Ethernet, ARINC-429, RS-485, etc.).
• Aware of secure coding practices and integrate security verification into the software development lifecycle.
• Collaborate with systems and hardware teams to ensure defense-in-depth and secure architecture design.
• Participate in security verification and validation (V&V) including penetration testing, fuzz testing, and security audits.
• Interface with certification authorities, DERs, and cybersecurity focal teams to maintain compliance and documentation.
• Good understanding of DO-326A / ED-202A, DO-356A / ED-203A, DO 178C.
• Hands-on experience in threat modeling, vulnerability analysis, and security testing for embedded systems.
• Strong understanding of cryptography, key management, and secure communication protocols (TLS, AES, ECC).
• Exposure to cybersecurity tools for:
  o Static and Dynamic Code Analysis, Vulnerability Scanning & Pen Testing, Secure Architecture and Risk Assessment, Secure Coding Checkers / Compliance Tools.

MBD Responsibilities and Required Skills:

• Experience in Model-Based Design (MBD) activities for control and monitoring systems using MATLAB/Simulink/Stateflow.
• Develop, simulate, and validate high-level and low-level models traceable to system and software requirements.
• Implement auto-code generation using Embedded Coder or TargetLink for embedded processors.
• Ensure MBD processes comply with DO-331 (Model-Based Development and Verification Supplement to DO-178C).
• Conduct model reviews, simulation verification, and coverage analysis for certification evidence.
• Lead SIL, PIL, and HIL test activities ensuring functional and safety validation.
• Support tool qualification activities for modeling, code generation, and analysis tools as per DO-330.
• Experience in MATLAB, Simulink, Stateflow, and Embedded Coder / TargetLink.
• Deep knowledge of model architecture, simulation, and code integration.
• Experience with requirements traceability using Polarion, DOORS, etc.
• Familiarity with tool qualification, model coverage, and test automation (Simulink Test).
• Understanding of real-time control design, signal conditioning, and plant modeling.

Preferred Tools & Platforms:

• MATLAB / Simulink / TargetLink / Embedded Coder
• Polarion / DOORS /
• Polyspace / CodeSonar /
• Git / SVN
• TI C2000, TMS570 or ARM-based microcontrollers

SW Embedded Developer Responsibilities and Required Skills:

• Proficiency in Embedded C/C++ programming
• Low-level device driver development expertise.
• Experience with TI microcontrollers
• Debugging and troubleshooting embedded hardware/software integration
• Familiarity with DO-178 safety standards
• Knowledge of communication protocols (I2C, SPI, UART, CAN)
• Hardware interfacing and register-level programming
• Version control and documentation best practices
• Requirements and design writing (including architecture, timing sequence, data flow/control flow)
• Automation (any scripting tools Perl, python, shell batch, etc.) Preferably Java Scripting
• Performance analysis (Memory, stack and WCET)
• Code static Analysis (preferably Polyspace otherwise any tools) and bug fixes for both static and dynamic code violations.
• Any CI/CD Tools or AI tools advantage – added advantage
• Timer based scheduler implementation (bare-metal OS and task scheduling/management) and optimization
• Integrator application development life cycle
• PR/CR life cycle
