The Sr Systems Engineer champions the viewpoint of the integrated whole during system development and works to glue segments and subsystems together via top-down decomposition of stakeholder requirements, traceability through development artifacts, and bottom-up validation and verification of the system. They shepherd the team through technical development milestones, track performance measures and identify technical risks to arrive at a compliant and cohesive system solution. The Sr Systems Engineer is a promoter of Systems Engineering principles and has expertise across the major systems engineering skills including requirements management, system architecture development, concept of operation definition, system integration and system verification. The Sr Systems Engineer leads teams to execute systems engineering scope and helps to develop systems thinking in others. In this role, you will lead the specification, architecting, and integration of complex system solutions while collaborating with cross-functional teams and subject matter experts to understand project requirements and objectives. You will oversee the derivation, decomposition, allocation, tracing, and management of system requirements and architectures, as well as define and document system concepts of operation. Leading development milestone reviews by creating artifacts and deliverables will be a key responsibility, alongside overseeing system integration and verification activities to ensure system functionality and performance. You will identify and manage technical risks, develop mitigation strategies, and contribute to continuous improvement initiatives by identifying areas for enhancement. Adhering to established engineering processes and standards will be essential, and you will communicate effectively with team members and stakeholders to ensure project alignment and successful execution. About You Our mission is driven by an unyielding commitment to advancing space-based technology in service of our customers and safeguarding national security. We seek individuals who are passionate about innovating beyond boundaries and relentlessly pursuing solutions that protect, preserve and empower - to join us in this critical mission. ## Related Videos - [Security Pitfalls for Software Engineers](https://www.wearedevelopers.com/videos/726-security-pitfalls-for-software-engineers) - [Leveraging Large Language Models for Legacy Code Translation: Challenges and Solutions](https://www.wearedevelopers.com/videos/1157-leveraging-large-language-models-for-legacy-code-translation-challenges-and-solutions) - [DevSecOps: Injecting Security into Mobile CI/CD Pipelines](https://www.wearedevelopers.com/videos/273-devsecops-injecting-security-into-mobile-ci-cd-pipelines) - [DevSecOps culture](https://www.wearedevelopers.com/videos/783-devsecops-culture) - [Crew Management System for Airlines: Plan duties for pilots & flight attendants worldwide](https://www.wearedevelopers.com/videos/1444-crew-management-system-for-airlines-plan-duties-for-pilots-flight-attendants-worldwide) - [Building a hypercar from scratch](https://www.wearedevelopers.com/videos/607-building-a-hypercar-from-scratch) ## Related Articles - [How We Built a Worry-Free System That Runs for 10+ Years – And What We’d Do Again](https://www.wearedevelopers.com/magazine/751-how-we-built-a-worry-free-system-that-runs-for-10-years-and-what-we-d-do-again) - [What is Software Engineering?](https://www.wearedevelopers.com/magazine/289-what-is-software-engineering) - [Software Engineer Career: Things You Should Know](https://www.wearedevelopers.com/magazine/143-software-engineer-career-things-you-should-know) - [Highest Paying Tech Companies for Developers](https://www.wearedevelopers.com/magazine/220-highest-paying-tech-companies-for-developers) - [Is Software Engineering Hard?](https://www.wearedevelopers.com/magazine/448-is-software-engineering-hard) - [The Ultimate Software Engineer Career Path Guide for 2023](https://www.wearedevelopers.com/magazine/146-the-ultimate-software-engineer-career-path-guide-for-2023)
