Team and Role Overview:

At Relativity, we reimagine the way rockets are built and flown. We are looking for a Propulsion Engineer to help us achieve our ambitious goal of launching a 3D printed rocket. You will report directly to the Director of Propulsion. A high degree of autonomy and initiative is required.

The Mission/Outcomes and Objectives:

To support our mission of changing people’s conception of the way rockets are built and flown, you will be designing critical flight parts, ground support equipment, test fixtures, and tooling. This encompasses a wide variety of designs (full cycle—from conceptualization, design, prototyping, manufacturing, testing, design, and implementation.) As a Propulsion Engineer, you will have a heavy hand in the development of various components of the Aeon-1 engine. You will be directly contributing to the design, test, integration, and operation of the components for the first flight engine. You will also provide design, analysis, build, and testing support to the propulsion team as we undergo an extensive development testing.

Here are some examples of projects you will be working on:

- Injector, Thrust Chamber Assembly, and Ignition Systems

- Turbomachinery design and development

- Main Propellant Control Valves and Actuators

- Interconnecting Engine Hardware and Ancillary Systems

- Heat Exchangers

- DMLS Process Development and Application

Candidate Profile: (Who is the person we are looking for?)

In order to be successful in this role, you should be someone who thrives in ambiguity and is able to drive their own projects to completion. You must have the passion, tenacity and resolve to work through challenging issues unique to rocket propulsion systems. Ideally, you are someone who has come from a fast paced, aerospace environment, having completed difficult projects while collaborating effectively with multidisciplinary groups.

On a day to day, a successful candidate will:

· Work within our CAD program, Creo, to model design concepts

· Perform analysis (hand calculations and advanced FEA/CFD analysis) to size flow paths and structural components

· Work with in-house manufacturing teams and suppliers to fabricate test hardware to optimize producibility

· Functionally test hardware to characterized operational capability and validate requirements

Minimum Required Skills and Competencies: 

• An undergraduate or graduate degree (BS/MS/PhD) in engineering with 3+ years experience developing liquid rocket engines.
• Strong understanding of launch vehicle propulsion systems and components.
• ProE/CREO experience or equivalent with an understanding and application of geometric dimensioning and tolerancing (GD&T) per ASME Y14.5-1994.
• Proficient in the physics of compressible and incompressible flow, thermodynamics, multiphase flow, mechanics, and materials.
• Good understanding and experience working with advanced manufacturing techniques to design for manufacturability and assembly.

Preferred Skills and Competencies: 

• Experience leading small teams in complex engineering projects.
• Experience with powder bed additive manufacturing and automation techniques.
• Familiarity with industry-standard propulsion design and analysis codes.
• Experience developing propulsion system design and analysis codes.
• Experience managing subcontractors, suppliers, and vendors.
• 5+ years experience developing liquid rocket engines.

This position must meet Export Control compliance requirements, therefore a United States Person as defined by 22 C.F.R. § 120.15 is required.
