• Review code, provide clear feedback, and enforce adherence to established development processes, style guides, and design standards to maintain consistency and quality across the codebase.
• Design and implement unit and integration tests for both self-authored and peer-authored code.
• Utilize version control systems to create feature branches, push code, and merge approved code into production branches.
• Contribute to the onboard software architecture through design proposals and collaborative review
• Participate in the review and enhancement of software development processes and design standards.
• Coordinate with downstream teams on the distribution and adoption of the latest releases.
• In addition to responsibilities within onboard software, you’ll have the opportunity to directly be involved in operating our on-orbit fleet of satellites.
