About The Position

SAIC is seeking a highly motivated and experienced Senior Software Engineer to support the development, integration, and implementation of a Common Translator software solution to bridge communication between legacy aircraft systems and a new Identification Friend or Foe (IFF) transponder at our customer site in Huntsville, AL. The ideal candidate will possess a strong understanding of both software engineering concepts and avionics systems, particularly in IFF and legacy aircraft communication protocols. Additionally, the ideal candidate will be responsible for designing, coding, testing, and supporting reliable, mission-critical software systems. This position provides the opportunity to work in a dynamic, technically rigorous environment, contributing to the successful modernization of critical defense and aerospace systems while ensuring compatibility, accuracy, and performance in a systems integration environment. This position is hybrid - allowing for onsite at S3I complex when required, SAIC or homesite at other times.

Requirements

Strong understanding of software engineering concepts
Strong understanding of avionics systems, particularly in IFF and legacy aircraft communication protocols
Experience with programming languages such as C++, C#, or Python
Experience with development environments and tools (e.g. Visual Studio, ADO) tailored to embedded systems and avionics applications
Experience with interoperability standards, including IFF modes, MIL-STD-1553, ARINC 429, and other avionics data bus standards
Experience with unit tests, system integration tests, and automated testing processes
Experience with simulation tools and test rigs
Experience with debugging and troubleshooting software and hardware integration issues
Experience working closely with cross-functional teams, including hardware engineers, systems engineers, and test engineers, customer entities and partners
Experience reporting technical progress, presenting system designs, and participating in peer reviews, design reviews, and technical interchange meetings
Experience creating and maintaining detailed software design documentation, user manuals, and test plans
Knowledge of relevant software development standards, security protocols, and industry certifications such as DO-178C and cybersecurity requirements for military systems

Responsibilities

Design and implement modular and scalable software solutions for the Common Translator system to ensure compatibility between existing avionics systems and the new IFF transponder
Develop software that interprets incoming data from legacy aircraft systems and converts it to the required data format for the new transponder, and vice versa
Use programming languages such as C++, C#, or Python, along with development environments and tools (e.g. Visual Studio, ADO) tailored to embedded systems and avionics applications
Collaborate with systems engineers to fully understand technical requirements, interfaces, and legacy system specifications
Ensure seamless integration of the Common Translator with both existing and emerging systems while maintaining adherence to interoperability standards, including IFF modes, MIL-STD-1553, ARINC 429, and other avionics data bus standards
Develop and execute unit tests, system integration tests, and automated testing processes to ensure software quality and reliability
Use simulation tools and test rigs to validate the performance of the Common Translator software in laboratory and field environments
Debug and troubleshoot software and hardware integration issues to resolve defects rapidly
Work closely with cross-functional teams, including hardware engineers, systems engineers, and test engineers, customer entities and partners to achieve program goals
Report technical progress, present system designs, and participate in peer reviews, design reviews, and technical interchange meetings with project stakeholders and customers
Create and maintain detailed software design documentation, user manuals, and test plans
Ensure compliance with relevant software development standards, security protocols, and industry certifications such as DO-178C and cybersecurity requirements for military systems
