Job summary

Cowboy Space Corp. in the United States is seeking a Powerpack Engineer, Level II to own turbopump components from concept through hot fire testing and flight. You will trade designs, define interfaces, and ensure hardware meets requirements with rigorous analysis and testing.

This role demands CAD proficiency, GD&T mastery, turbomachinery knowledge, and hands-on build/test experience. Preferred candidates have advanced degrees and experience with rocket propulsion hardware.

Qualifications

• Bachelor's degree in Aerospace, Mechanical, or related engineering field.
• Proficiency in 3D CAD and GD&T with released, manufacturable design definitions.
• Working knowledge of turbomachinery fundamentals.
• Hands-on experience taking a design through build and test.
• Familiarity with material and manufacturing process selection for high-stress, high-cycle applications.
• US citizen or eligible for work in the U.S. (as applicable).

Responsibilities

• Own the mechanical design of turbopump components from concept through hot fire testing and flight; CAD models, tolerances, GD&T, materials, process specs, analysis cycles, and requirements traceability.
• Bring a culture of creativity to every design challenge and see solutions through to completion.
• Integrate hydro, aero, structures, secondary flow, and thermals constraints into a single coherent design.
• Control configuration and pedigree for components across build, test, and refurbishment cycles.
• Drive hardware through manufacturing and build: fabrication, first article review, and nonconformance disposition.
• Provide real-time support and data reduction for engine tests and assist anomaly investigations.

Job description

Powerpack Engineer, Level II | Job Description

Cowboy Space Corp. is building the infrastructure to power and connect the orbital economy. Our satellites operate in Low Earth Orbit to collect sunlight and enable a new class of capabilities—from powering on-orbit compute, to transmitting energy via infrared lasers (space-to-earth and space-to-space), powering on-orbit compute to delivering secure, high-bandwidth optical data. By rethinking how energy and data are generated and distributed in space, we’re unlocking entirely new ways to operate both in orbit and on Earth.

Founded in 2024 by Baiju Bhatt (co-founder of Robinhood), Cowboy Space Corp. is backed by leading investors and built by a team from top aerospace and defense organizations. We’re moving quickly to solve complex technical challenges and build a new category of space infrastructure.

About the Role:

The turbopump is the heart of the engine and sets its performance ceiling. In this role you are the responsible engineer for a set of turbopump components: their design definition, their interfaces, how they get built, and how they perform on the stand. You will trade designs, and you will own the argument that your hardware meets its requirements, including which of those requirements get closed by analysis and which have to be proven in a test cell. Your parts go from ore to orbit with your name on them.

Responsibilities:

• Bring a culture of creativity to every design challenge. Own each solution or improvement with true accountability, seeing it through to completion.
• Own the mechanical design of turbopump components and subassemblies from concept through hot fire testing and flight: CAD models, design definitions, tolerances, GD&T, material and process specifications, analysis cycles, and the requirements each component has to meet.
• Integrate constraints from hydro, aero, structures, secondary flow, and thermals into a single coherent design.
• Control the configuration and record pedigree for your components across build, test, and refurbishment cycles.
• Drive hardware through manufacturing and build: fabrication, first article review, and nonconformance disposition.
• Provide real-time support and data reduction for component and engine tests and provide support to anomaly investigations.

Basic Qualifications:

• Bachelor’s degree in Aerospace, Mechanical, or related engineering field.
• Proficiency in 3D CAD and in producing released, manufacturable design definitions with sound geometric dimensioning and tolerancing (GD&T), and tolerance stack-ups.
• Working knowledge of turbomachinery fundamentals.
• Hands-on experience taking a design through build and test.
• Familiarity with material and manufacturing process selection for high-stress, high-cycle applications.
• Must be a U.S. citizen or national, U.S. permanent resident (current Green Card holder), or lawfully admitted into the U.S. as a refugee or granted asylum.

Preferred Qualifications:

• 2+ years of turbomachinery or turbopump design experience.
• Master’s degree or Ph.D. in Aerospace, Mechanical, or related engineering field.
• Experience with liquid rocket engine turbopumps or reusable propulsion systems, or experience with adjacent rotating machinery. Gas turbines, industrial pumps, compressors, and turbochargers all build fundamentals that carry over to turbopump design.
• Experience with detailed design and analysis of fluid components (impellers, diffusers, volutes, turbines, and secondary flow), dynamic seals, and structures.
• Experience leading a root cause investigation on hardware you owned and carrying the corrective action through to closure.
• Familiarity with cryogenic hardware design and cryogenic material behavior.
• Experience with multiple methods of manufacture (additive, forgings, castings).
• Experience at a fast-moving, hardware-focused startup or early-stage program.
• Track record of picking up unfamiliar problems quickly and closing them out with minimal direction.

Compensation and Benefits

The salary range for this position is $125,000 – $155,000 annually. The actual base salary offered will depend on factors such as job-related skills, experience, qualifications, and internal equity.

• Equity in Cowboy Space Corp.
• Employees and their eligible dependents may enroll in medical, dental, and vision insurance
• 401(k) retirement savings plan
• Paid time off
• 10 paid holidays per calendar year
• Paid parental leave
• Relocation assistance if applicable
• Daily lunch in the office and a fully stocked kitchen with beverages and snacks

ITAR Requirements

• Export Control Requirement: To conform to U.S. Government space technology export regulations, including the International Traffic in Arms Regulations (ITAR), applicants must be a U.S. citizen, lawful permanent resident of the U.S., protected individual as defined by 8 U.S.C. 1324b(a)(3), or eligible to obtain the required authorizations from the U.S. Department of State.
