Propulsion Engineer

About Gravitics

At Gravitics, we're not exploring space—we're building it. We're creating the infrastructure for a thriving space economy, enabling humanity to flourish beyond Earth. Our vision is bold, but we're not just dreamers; we're doers. We design and manufacture large-scale orbital structures that enable commercial operations while meeting the requirements of defense and government missions. 

Our systems are built to scale and built to last—bridging commercial innovation with mission-critical performance. If you're ready to lay the foundations for a new era in space, embrace a culture of relentless learning and innovation, and contribute to a future where humanity's reach extends farther, Gravitics is the place for you. Let's build the future together.  

About the Role

We are looking for rockstars who can work the full product lifecycle of an in-space propulsion system from design through build and integration. You will own major fluid subsystems to develop a propulsion system that operates flawlessly regardless of the mission.

Responsibilities

• Design, build, and test propulsion fluid systems, including feed systems, tank pressurization, propellant management, and associated fluid components
• Take ownership of propulsion subsystem architecture elements, from concept definition through hardware integration and test
• Lead system-level trade studies to evaluate performance, weight, power, and cost
• Plan and execute propulsion integration and test campaigns, including component, subsystem, and full vehicle testing
• Generate and maintain engineering documentation such as requirements, interface control documents (ICDs), test plans, and fluid system schematics
• Work cross-functionally with structures, thermal, avionics, and GNC teams to ensure propulsion system compatibility with vehicle-level performance
• Support environmental qualification and acceptance testing, including thermal-vacuum, vibration, and leak/proof pressure testing

About You

You’re a successful candidate if you are a giver, not a taker. You make things happen. You are exceptional at several things, yet willing to take on efforts in areas of weakness. 

Required Attributes

• 5+ years of experience in mechanical or aerospace engineering

• Bachelor’s degree in aerospace engineering, Mechanical Engineering, or another applicable field

• Working knowledge of propulsion or fluid system components (feed systems, pressurization, valves, regulators, or similar)

• Exposure to one or more of the following:

• Liquid or gas propulsion system design
