The Role
As a Senior GNC Engineer at Relativity Space, you will collaborate with a multidisciplinary team to develop control and guidance solutions for the Terran R rocket. Your role will involve designing and implementing control algorithms, assessing vehicle controllability, and supporting ground and flight tests.
Summary Generated by Built In

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.

About the Role:

You will work closely with a multidisciplinary vehicle engineering team to develop control and guidance solutions, assess the impact of designs on vehicle controllability and performance, work with the flight software team to implement control algorithms and navigation solutions into Terran R, and make recommendations for changing vehicle configuration to meet controllability and performance goals. Additionally, you will support ground and flight tests for Terran R launch vehicles.

About You:

  • An undergraduate or graduate degree (BS/MS/PhD) in engineering or related discipline
  • 5+ years of experience working on GNC solutions in aerospace
  • Specialization in flight controls, navigation, or guidance for launch vehicles or satellites
  • Experience with C++ and Python

Nice to haves but not required:  

  • Experience developing flight code
  • Ability to work in a fast-paced and intense start-up environment
  • Ability to complete projects with ownership of end-to-end solutions with a high degree of independence.
  • Experience in control systems, orbital mechanics, classical dynamics, aerodynamics, sensors and actuators, and modeling and simulation

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.

What We Do

A rocket company at the core, Relativity Space is on a mission to become the next great commercial launch company. Terran R, our medium-to-heavy lift reusable launch vehicle, will reliably deliver payloads to orbit on-time and on-budget for customers – meeting the needs of growing demand for space infrastructure. Leveraging the benefits of additive manufacturing to design, test, and iterate at a pace unmatched in the industry, we are changing the way rockets are built and flown.

Our long-term goal is to create humanity’s industrial base on Mars, paving the way for interplanetary life to fundamentally expand the possibilities of the human experience. The first step toward this vision starts here on Earth, by building the next great commercial launch company.

Why Work With Us

For 60 years, aerospace manufacturing has relied on fixed tooling and complex supply chains to slowly build rockets comprised of hundreds of thousands of parts. Leveraging advances in additive manufacturing, Relativity Space is strategically focused on reducing vehicle complexity, cost, and time to market.
