Sr Multibody Dynamics Engineer

At Relativity Space, we have two audacious goals: to build the next great commercial launch company with Terran R and to become America's leading force in additive manufacturing innovation. Both contribute to our long-term vision of creating humanity's industrial base on Mars, paving the way for interplanetary life to expand the possibilities of the human experience. This journey begins right here on Earth - where we design, build, and fly rockets to deliver customer payloads to orbit. Terran R, our medium-to-heavy lift reusable rocket, fulfills the growing demand for launch capacity, thanks to our iterative approach that accelerates design, testing, and development while minimizing costs. While our groundbreaking research and development in 3D printing pushes the boundaries of large-scale additive manufacturing.

Your journey with us is more than just a job - it's an opportunity to shape the future of aerospace technology, additive manufacturing, and the human experience alongside a community of passionate, creative individuals. Join us on this extraordinary journey, as we work together to transform our vision into reality.

About the Team:

Relativity's Integrated Performance teams ensure that our products work across all systems and disciplines, from trajectory design to aerodynamics to reliability analysis and beyond. Our groups size the Terran R rocket, design its missions for customer success, reliability, and reusability, and ensure that every system on the rocket and ground is engineered correctly for the demanding environments of launch and entry. Recently, we completed the preliminary design and analysis of Terran R including Relativity's first-ever work on launch vehicle reusability, spanning advanced trajectory simulations, wind tunnel testing, and structures analysis, among many other projects.

The Multibody Dynamics team works collaboratively with adjacent Flight Sciences teams like Loads and Aerodynamics and across the Mechanisms, Structures, Fluids, and GNCP teams to develop robust separation and deployment system architectures, generate associated loads, maintain and improve related analysis tools, provide design and test guidance, and contribute to performance trades on time and budget while meeting our technical requirements. A high degree of autonomy along with an ability to prioritize work in our fast-paced environment is required.

About the Role:

• Architect and analyze Terran R dynamic systems including stage separation, payload fairing separation, and landing
• Collaborate with hardware owners and other analysis teams to identify opportunities to improve performance, reliability, robustness, or simplicity of separation and deployment architectures
• Work closely with Aero, GNCP, Loads, Fluids, and hardware teams to manage analysis inputs, outputs, and indicators to help ensure successful design and operability of separation and deployment systems and interfacing hardware
• Contribute to roadmaps for engineering analysis in collaboration with leadership
• Support test campaigns relating to vehicle separation and deployment components/systems
• Drive maturation of analysis processes, methodology development, and data and results processing and communication

About You:

• Undergrad degree in engineering or a related field
• 5 years of experience developing/performing multibody dynamic analysis on a launch vehicle, automotive, or related program
• Proficiency in Python or similar
• Familiarity with statistics and data analysis

Nice to haves but not required:

• A graduate degree (MS) in engineering or related field and 6 years relevant experience
• Experience developing analysis toolsets/workflows using both custom and commercial software
• Experience leading anomaly resolutions/failure investigations
• Experience in an engineering analysis team through a full program lifecycle
• Experience with hardware build and/or test

At Relativity Space, we are committed to transparency and fairness in our compensation practices. Actual compensation will be determined based on experience, qualifications, and other job-related factors.

Compensation is only one part of our total rewards package. Relativity Space offers competitive salary and equity, a generous PTO and sick leave policy, parental leave, an annual learning and development stipend, and more! To see some of the benefits & perks we offer, please visit here.
