Job Description:

Job Description Job Description At Relativity Space, we're building rockets to serve today's needs and tomorrow's breakthroughs. Our Terran R vehicle will deliver customer payloads to orbit, meeting the growing demand for launch capacity. But that's just the start. Achieving commercial success with Terran R will unlock new opportunities to advance science, exploration, and innovation, pioneering progress that reaches beyond the known. Joining Relativity means becoming part of something where autonomy, ownership, and impact exist at every level. Here, you're not just executing tasks; you're solving problems that haven't been solved before, helping develop a rocket, a factory, and a business from the ground up. Whether you're in propulsion, manufacturing, software, avionics, or a corporate function, you'll collaborate across teams, shape decisions, and see your work come to life in record time. Relativity is a place where creativity and technical rigor go hand in hand, and your voice will help define the stories we're writing together. Now is a unique moment in time where it's early enough to leave your mark on the product, the process, and the culture, but far enough along that Terran R is tangible and picking up momentum. The most meaningful work of your career is waiting. Join us. About the Team: At Relativity Space, our Production Control Team plays a mission-critical role in enabling our vision of revolutionizing aerospace manufacturing. This team is responsible for planning and scheduling the entire product lifecycle—from initial components and engine builds to full-stage vehicle integration. What makes our team unique is the depth and extensiveness of our influence across the organization. We work closely with Production, Supply Chain, Program Management, Engineering, and Leadership to ensure that every part, assembly, and milestone is aligned with the bigger picture. Our planners sit at the intersection of strategic execution and tactical problem solving, helping to translate complex technical goals into clear, achievable plans. We thrive in an environment where no two days are the same, and where adaptability, ownership, and curiosity are essential. Whether it's building capacity models from scratch, creating rate-based schedules for a new production line, or driving alignment across multiple hardware owners, this team is empowered to lead and deliver clarity where it's needed most. If you're energized by the idea of scheduling the future of spaceflight, being a core driver of operational readiness, and collaborating with some of the most innovative teams in the industry—then this is the team for you. About the Role: In this role, we are seeking an experienced Senior Production Planner to join our growing team and play a key role in transforming our manufacturing operation into a high-output, rate-based system. This individual will own and drive planning deliverables tied to production execution, schedule transparency, and build readiness, while helping define scalable processes that support production rate acceleration. Lead the development and execution of complex, integrated production plans across multiple programs, covering all phases from raw material through final vehicle integration. Lead CTB reviews for assigned builds, ensuring shortages are tracked, mitigated, and escalated as needed. Maintain close alignment with propulsion integration teams through daily scrum updates and issue resolution. Use CTB trends to inform risk management, resource allocation, and scheduling adjustments. Support scaling of CTB workflows into automated, system-driven readiness tools. Drive long-range planning strategies by aligning capacity, material availability, and build requirements to program objectives and rate targets. Own lead-time analysis to proactively identify systemic risks, implement recovery plans, and ensure on-time delivery of hardware across interdependent work centers. Manage and continuously improve advanced Clear to Build processes, working across engineering, supply chain, and manufacturing to eliminate blockers and optimize readiness at every stage. Support the deployment of scalable planning tools, automation, and analytics that enhance forecasting accuracy, enable scenario modeling, and increase operational agility. Represent the production planning function in cross-functional reviews, program readiness gates, and executive-level updates, providing transparent communication of planning health, risks, and mitigation actions. Mentor and guide planners across the organization, promoting planning excellence and driving consistency in standards, reporting, and best practices. About You: Bachelor's degree or equivalent 3 years of experience in production planning, scheduling, or manufacturing operations, preferably in aerospace, automotive, or other complex hardware environments. Demonstrated expertise in capacity planning, MRP/ERP systems, and integrated scheduling techniques. Experience working in a fast-paced, scaling production environment with evolving processes. Strong analytical skills with the ability to simplify and communicate complex schedule data to various stakeholders. Proven track record of cross-functional collaboration and effective problem-solving. Excellent organizational and communication skills—both written and verbal. Skilled with resource loaded schedules using Smartsheet, MS Project, or comparable scheduling software. Nice to haves but not required: Aerospace, automotive, or high-rate manufacturing experience. Experience with rate-based production transitions or new product introduction. Exposure to digital planning tools and/or planning automation initiatives. Familiarity with Clear to Build methodologies and shortage management. Excellent analytical, communication, and problem-solving skills. SQL query experience is a plus for supporting data-driven planning and reporting. At Relativity Space, we are committed to transparency and fairness in our compensation practices.
