• Implement and maintain compliance with relevant ARINC standards, including ARINC 429, 618, 620, 622, 661, 739, and 615.
• Apply DO-178B/C processes and contribute to the development of high-integrity, safety-critical software that meets stringent aviation certification objectives.
• Perform requirements analysis, verification and validation (V&V), structural coverage analysis (SCA), debugging, troubleshooting, and unit, integration, white-box, and verification testing.
• Support software-software and hardware-software integration, identify complex system-level issues, and drive effective technical resolutions.
• Prepare for and participate in Stages of Involvement (SOI), certification reviews, technical audits, and engagements with internal and external compliance authorities.
• Work closely with systems, software, integration, verification, and certification teams to deliver robust, reliable, and high-quality solutions.
• Contribute to requirements management, reliability analysis, risk mitigation, process optimization, and continuous improvement across the software development lifecycle.
• Use network analyzers, simulation environments, and software development and verification tools to validate performance and troubleshoot complex avionics systems.

What you'll need

• Bachelor's or Master's degree in Engineering (B.Tech/M.Tech), with a foundation in avionics systems and software architecture.
• 12+ years of avionics software development and verification experience.
• Strong programming proficiency in C or C++ and Python.
• Solid understanding of avionics systems and architectures, including Data Link, Communication, Navigation and Surveillance (CNS), Flight Management Systems (FMS), Flight Control Systems (FCS), and aircraft displays.
• Strong understanding of the Software Development Lifecycle (SDLC), covering requirements analysis, software design, coding, integration, verification, and validation.
• Practical exposure to DO-178B/C processes and safety-critical software development.
• Hands-on experience with V&V, structural coverage analysis, debugging, troubleshooting, and white-box, unit, integration, and verification testing.
• Experience with software development and verification tools such as VectorCAST, PyATE, RapiTest, Git, and Subversion.
• Familiarity with real-time operating systems and network analyzer tools used for communication and performance testing.
• Understanding of Agile methodologies and experience working in an Agile engineering environment.

Nice to have
