Principal Materials Engineer

At Relativity Space were building rockets to serve todays needs and tomorrows breakthroughs. OurTerran R vehicle will deliver customer payloads to orbit meeting the growing demand for launchcapacity. But thats just the start. Achieving commercial success with Terran R will unlock newopportunities to advance science exploration and innovation pioneering progress that reaches beyondthe known.

Joining Relativity means becoming part of something where autonomy ownership and impact exist at every level. Here youre not just executing tasks; youre solving problems that havent been solved before helping develop a rocket a factory and a business from the ground up. Whether youre in propulsion manufacturing software avionics or a corporate function youll 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 were writing together. Nowis a unique moment in time where its early enough to leave your mark on the product the process andthe culture but far enough along that Terran R is tangible and picking up momentum. The mostmeaningful work of your career is waiting. Join us.

About the Team:

The Materials and NDE (Non-Destructive Evaluation) team plays a central role in enabling Terran R to fly re-fly and scale: developing characterizing and inspecting materials and processes across all parts of the vehicle. From welding and additive manufacturing to advanced composites the team works at the intersection of innovation and execution balancing performance and reliability with cost quality and schedule. As we move toward first flight and beyond the challenges become more exciting offering opportunities to shape how we design and develop for re-use. With ownership across products systems and disciplines engineers gain broad exposure and drive key decisions across design manufacturing and operations.

About the Role:

The Materials Discovery Lab is a small autonomous lab which works synergistically with the Materials Engineering department. The aim is to push the frontiers of extreme environment materials that enable short- and long-term missions of space exploration. The high-performance materials can also have broad impact on big technological challenges outside aerospace where material is the limit. Our mission is to combine the fundamental science and real world requirements through deep materials expertise which will lead to unique industry leading solutions. Some of the specific areas include:

• Provide new material solutions to enable upcoming Relativity Space missions e.g. reusable thermal protection for Terran R
• Solve grand challenges that confront the space community e.g. heatshields for Mars and Moon missions reusable heatshield solutions for LEO missions
• Tackle strategic areas such as carbon and ceramics to bridge long standing gaps in the thermal protection of extreme of the extremes such as hypersonic leading edge and engine components

Youll be working with a small team of experienced and passionate builders who are laser focused on solving real world impactful problems. If you have the can do attitude and enjoy hands-on work youll find the environment conducive to creative problem solving and enjoy the day-to-day fun of discovery.

As a hands-on project manager with deep subject matter expertise you will lead day-to-day operations of the materials discovery lab. You will plan coordinate and facilitate the implementation that supports rapid materials prototyping and testing. You will work closely with the principal investigator (PI) on project planning experimental designs data acquisition and analysis as well as training and mentoring team members to efficiently execute various projects and major responsibility is to supervise the acquisition setup operation troubleshooting and maintenance of equipment and instruments that support materials prototyping and testing.

About You:

• Bachelor or masters degree in Materials Science Materials Engineering Mechanical Engineering or a relevant field
• 10 years hands-on experience in aerospace high temperature materials development and testing

Nice to haves but not required:

• Proficiency and hands on experience in thermal/chemical/mechanical testing
• Analyzing and fabricating materials Differential scanning calorimetry Thermogravimetric analysis Intron tensile testing Laer Flash analysis Dilatometry Rheometry FT-IR X-ray diffraction Scanning Electron Microscopy Cryomilling Power metallurgy CVD/CVI operation
• Experience in project management and mentoring/training junior team members
