Senior Systems Engineer

Senior Systems Engineer  Location: Gravitics – Seattle WA, Colorado, (with future travel/support to other company locations as required) Department: Engineering Reports To: Head of Engineering  About Gravitics   At Gravitics, we're not exploring space - we're building it. We're creating the infrastructure for a thriving space economy, enabling humanity to flourish beyond Earth. Our vision is bold, but we're not just dreamers; we're doers. We design and manufacture large-scale orbital structures that enable commercial operations while meeting the requirements of defense and government missions.   Our systems are built to scale and built to last—bridging commercial innovation with mission-critical performance. If you're ready to lay the foundations for a new era in space, embrace a culture of relentless learning and innovation, and contribute to a future where humanity's reach extends farther, Gravitics is the place for you. Let's build the future together.    About the Role  We are seeking a highly capable Systems Engineer to support technical execution of the commercial spacecraft program from architecture development through qualification, integration, test, launch, and mission operations. This role sits at the center of the program and works directly with Chief Engineers, subsystem leads, Program Management, Manufacturing, Integration & Test, Mission Assurance, and suppliers to ensure the spacecraft functions as an integrated system — not just a collection of subsystems. The ideal candidate is technically broad, execution-focused, comfortable in ambiguity, and able to balance engineering rigor with program realities including schedule, manufacturability, integration flow, and risk. This position will support development of human-rated spacecraft systems and therefore requires strong systems thinking, configuration discipline, verification planning, and cross-functional leadership.  Responsibilities  Support development and management of spacecraft system architecture, requirements, interfaces, and verification approaches for the program  Translate mission and program objectives into clear subsystem and vehicle-level technical requirements  Develop and maintain system specifications, interface control documents (ICDs), CONOPS, verification matrices, and technical baselines  Drive technical integration across:  Structures and mechanisms  Pressure systems  Propulsion systems  Avionics and software  Thermal systems  ECLSS / crew environment considerations  Docking and payload interfaces  Ground systems and GSE  Support program technical reviews including:  SRR  PDR  CDR  TRR  FRR  Coordinate system-level trades balancing:  Performance  Mass  Safety  Reliability  Manufacturability  Testability  Schedule and cost impacts  Work closely with Manufacturing and Integration & Test teams to ensure designs are producible, inspectable, and verifiable  Support development of system verification and validation plans including qualification, acceptance, protoflight, and integrated vehicle testing  Participate in anomaly resolution, failure investigations, and risk reduction activities  Support hazard analysis, FMEA/FDIR activities, and human-rating related assessments  Ensure configuration control and technical baseline integrity throughout the program lifecycle  Interface with customers, suppliers, and partner organizations as required  Help drive closure of technical issues rather than simply tracking them Required Qualifications  Bachelor’s degree in Aerospace Engineering, Mechanical Engineering, Systems Engineering, or related technical discipline  5+ years of experience in aerospace systems engineering or integrated vehicle development  Experience working on spacecraft, launch vehicle, aviation, defense, or other complex multidisciplinary systems  Strong understanding of systems engineering processes including:  Requirements development  Interface management  Verification and validation  Configuration management  Technical risk management  Experience supporting technical reviews and hardware development programs  Ability to operate across multiple engineering disciplines and communicate effectively with technical and non-technical stakeholders  Comfortable working in a fast-paced development environment with evolving priorities  Preferred Qualifications  Experience with human-rated spacecraft or crewed systems  Experience supporting pressure vessels, propulsion systems, docking systems, or orbital vehicle integration  Familiarity with NASA standards and spaceflight development processes  Experience with MBSE tools, requirements management tools, or digital engineering environments  Hands-on integration, test, manufacturing, or operations experience  Experience supporting qualification and environmental test campaigns  Familiarity with spaceflight safety and mission assurance processes  What Success Looks Like  Technical issues are identified early and driven to closure  Vehicle interfaces are clearly defined and controlled  Subsystems integrate cleanly into a functioning spacecraft  Verification activities are planned before hardware arrives at test  Engineering decisions consider program execution realities, not just ideal technical solutions  The program moves forward with increasing technical maturity and reduced integration risk  Compensation and Benefits Your level and base salary will be determined on a case-by-case basis and may vary based on the considerations of job-related knowledge and skills, education, and direct experience. Salary is just one component of the total employee package, which also includes company equity at an exciting time of company growth, as well as comprehensive medical, 401(k) retirement plan, a generous PTO policy, employee discounts, and more.  About Compliance To conform to U.S. Government space technology export regulations, including the International Traffic in Arms Regulations (ITAR) you must be a U.S. citizen, lawful permanent resident of the U.S., protected individual as defined by 8 U.S.C. 1324b(a)(3), or eligible to obtain the required authorizations from the U.S. Department of State.Gravitics is an Equal Opportunity Employer.
