## Description (the employer's text)

### 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
- Propellant management and fluid handling
- Hardware assembly, integration, and functional testing
- Thermodynamic or fluid dynamics analysis
- Ability to understand structural, fluid, and thermal designs from first principles
- Familiarity with CAD and FEA packages such as NX and NASTRAN or similar
- Ability to thrive in a fast-moving environment with evolving requirements and a high degree of ownership
### Bonus Points for

- Background in feed system design, pressurant system sizing, or propellant budgeting
- Hands-on experience assembling, integrating, and testing fluid system hardware
- Familiarity with propulsion-specific test environments, including proof/leak testing, hotfire testing, or pressure system qualification
- Experience conducting trade studies and optimizing propulsion system performance, weight, and reliability
- Familiarity with combustion, propellant chemistry, or reaction control system (RCS) design
- Experience with CFD, thermal fluid system modeling, and/or combustion modeling tools (e.g., Thermal Desktop, ANSYS Fluent, MATLAB/Simulink, ROCETS, GFSSP, CEA, TDK)
- Experience in high-reliability or safety-critical fluid systems with formal verification and validation practices
- Demonstrated ability to drive complex propulsion hardware from early design through acceptance testing
- Prior experience at launch vehicle, spacecraft, or propulsion-focused organizations
- Genuine enthusiasm for advancing propulsion technology and contributing to next-generation space systems
- Proficient understanding of drafting standards and GD&T (ASME Y14.5)
