• Support development and maintenance of the embedded Linux platform, including:
• Linux kernel configuration and debugging
• Bootloader and BSP support
• Root filesystem updates
• Core system services and systemd configuration
• Device driver integration and troubleshooting
• Platform scripts, tools, and configuration files
• Embedded Linux interfaces and processes
• Collaborate with team members, management, systems engineers, hardware teams, application teams, and mission operations to support project execution.
• Assist with understanding and expanding requirements based on high-level specifications, system needs, and mission use cases.
• Contribute to platform stability, security, and maintainability by:
• Investigating bugs and integration issues
• Supporting software updates and release activities
• Helping maintain reproducible builds
• Documenting changes, assumptions, and troubleshooting steps
• Identifying risks and raising issues early
• Communicating challenges, failures, and successes clearly
• Participate in technical design reviews and code reviews to improve quality and maintainability of deliverables.
• Support implementation of software architectures and designs that meet requirements.
• Develop code following project coding guidelines, process requirements, and review expectations.
• Assist with unit, integration, software-in-the-loop, and hardware-in-the-loop testing, including:
• Developing and executing unit tests
• Verifying requirements and interface behavior
• Supporting code coverage activities
• Helping analyze test results
• Supporting SITL and HITL integration and testing
• Capturing test results and release artifacts
• Work with other subsystems to support proper integration of platform software into the broader flight software design.
• Participate in implementation approach discussions by helping evaluate cost, complexity, schedule, and technical risk.
• Support continuous improvement of team practices, including:
• Improving documentation and knowledge sharing
• Automating repetitive development or test tasks
• Contributing to CI/CD improvements
• Participating in retrospectives and post-release reviews
• Helping improve release confidence and integration quality
• Grow technical ownership over time in areas such as:
• Yocto-based build systems
• Linux kernel customization
• Device trees and low-level hardware interfaces
• Embedded networking concepts
• Platform test automation
• Flight software deployment and update flows
• Software-in-the-loop and hardware-in-the-loop environments

Qualifications:
