Company Overview:  

A rocket company at the core, Relativity Space is on a mission to become the next great commercial launch company. Meeting the needs of a growing demand for space infrastructure, our rockets will revolutionize how we connect and communicate on Earth by getting satellites to space. We have developed a vertically integrated technology platform in which we leverage additive manufacturing, artificial intelligence, and autonomous robotics to 3D print rockets. Our unique approach enables rapid product iteration, allowing us to push the boundaries of what's possible today and unlock the full potential of 3D printing for tomorrow. Join us on this extraordinary journey, as we work together to transform our vision into reality.

Team:  

The Avionics team is responsible for the full lifecycle of all electronics and supporting hardware central to operating Relativity's rockets. The team designs, builds, tests, integrates, and operates the hardware which controls the rocket in flight, downlinks critical telemetry, keeps the public safe, and deploys our customers' payloads to orbit! Our hardware enables Relativity to reliably control our rockets while maintaining the flexibility to rapidly iterate our designs. As a member of this team, you will design innovative hardware solutions capable of surviving harsh launch and space environments. Your designs will support multiple vehicle systems such as sensors, propulsion, computing, actuation, energy management, and communications.

What you’ll do: 

• Own the design, analysis, and test/validation of battery assemblies within the Terran R avionics system from conception to qualification and production
• Collaborate with electrical engineering to design robust, high performance printed circuit board assemblies (PCBAs) through packaging trades and requirements definition
• Perform preliminary sizing for static and dynamic loads and thermal environments.
• Utilize 3D modeling and 2D drafting packages to deliver detailed designs with considerations for production and test
• Validate designs for flight through rapid prototyping, analysis, and test campaigns

What you need to know:  

• Minimum of 3 years of experience in a full cycle mechanical design engineering role
• Bachelor’s degree in Mechanical Engineering, Electrical engineering, or related field
• Professional Experience with multi-cell lithium-ion batteries, their failure modes, and mitigating fault propagation between cells
• Experience in designing products for launch vehicles, aerospace systems, automotive or other industries requiring high reliability designs
• Familiarity with methods of battery manufacturing and assembly, e.g. wire bonding
• Cell and battery Development test and qualification experience such as thermal runaway propagation
• Experience with 3D CAD software
• Understanding of electronics packaging design
• Experience with structural and thermal analysis
• Demonstrated project ownership and accountability with complex, multi-disciplinary technical projects

Nice to haves but not required:  

• Experience with finite element analysis methods
• Applied knowledge of geometric dimensioning & tolerancing (GD&T)
• Proficient with NX/Teamcenter CAD package
• Previous work on launch vehicle or spacecraft
• Experience with battery management systems (BMS)

Relativity Space offers competitive salary and equity, a generous vacation policy, an annual L&D stipend and more!
