As a Launch Systems Integration Engineer, you will serve as a key technical interface between York's spacecraft teams, launch vehicle providers, customers, and launch range organizations. You will lead the integration of York spacecraft onto launch vehicles, ensuring that technical requirements, interfaces, analyses, testing, and verification are aligned throughout the mission lifecycle. This role provides the opportunity to work across a broad range of engineering disciplines and has a direct impact on mission success. You will help resolve complex spacecraft-to-launch-vehicle interface challenges, coordinate technical decisions across multidisciplinary teams, and support missions from early integration through launch campaign and flight. We are open to candidates with varying levels of launch integration experience and will calibrate level based on experience. RESPONSIBILITIES Coordinate between York and launch vehicle teams to define and maintain environmental, mechanical, electrical, and other flight interfaces between the spacecraft, launch vehicle, and launch site. Coordinate cross-functional technical analyses between spacecraft and launch vehicle teams, ensuring inputs, assumptions, and outputs remain aligned and configuration-controlled. Lead the development and maintenance of Launch Systems Interface Requirements Documents (LSIRDs) and Interface Control Documents (ICDs) between the spacecraft and launch vehicle. Drive requirements allocation and flowdown between spacecraft functional teams, launch vehicle systems, and subsystem design teams, ensuring interface requirements are understood and appropriately implemented. Lead cross-functional resolution of spacecraft and launch vehicle interface conflicts, balancing technical requirements and developing system-level solutions that meet mission and customer needs. Develop and execute integration test plans to reduce technical risk and verify spacecraft-to-launch-vehicle hardware interfaces. Develop and manage verification and closure plans for interface requirements, ensuring compliance with York and customer expectations. Track requirement verification evidence and drive closure of ICD requirements through integration and launch readiness. Lead spacecraft launch integration and campaign activities at the launch range, coordinating technical teams and resolving issues through launch readiness and execution.   REQUIRED QUALIFICATIONS Bachelor's degree in engineering or a related technical discipline. 3+ years of experience in aerospace, space systems, or a related engineering field. Experience with spacecraft-to-launch-vehicle integration or other complex system integration activities. Experience working with technical requirements, interfaces, verification, and/or system-level analyses. Experience working hands-on with hardware or software technical projects. Strong written, verbal, and presentation skills. Ability to work effectively across multidisciplinary engineering teams. Ability to travel to launch sites, test sites, industry partner offices, and customer locations as needed. PREFFERED QUALIFICATIONS Experience with commercial rideshare, NSSL, or other launch integration programs. Experience leading spacecraft-to-launch-vehicle integration campaigns. Experience supporting launch campaigns at the Range. Experience with LSIRDs, ICDs, requirements allocation, and interface verification. Experience providing functional technical leadership, such as leading anomaly investigations or other cross-functional technical teams. Experience working directly with customers and/or launch vehicle providers. Proposal development and technical writing experience. Active secret clearance or higher LOCATION & TRAVEL This is an in-person role based at York Space Systems, with flexibility in day-to-day work arrangements based on team and mission needs. Regular collaboration with engineering teams and launch partners is an important part of the role. Some travel is expected to support spacecraft integration, testing, launch campaigns, customer engagements, and activities at launch sites and industry partner locations.
