Mid Career Spaceflight Hardware Propulsion Engineer

Amentum•Houston, TX

About The Position

Amentum is hiring a mid-career Spaceflight Hardware Propulsion Engineer for the JETSII Contract, supporting NASA’s deep-space exploration efforts. The role applies engineering principles to propulsion and spacecraft pressure systems, and supports hardware throughout its lifecycle—from analysis and concept development through fabrication, testing, integration, certification, and operation. The engineer coordinates with NASA program and project offices, spacecraft organizations, suppliers, contractors, and international partners; communicates technical status and risks; and may provide technical guidance and mentoring. Travel to supplier, test, integration, launch, or program locations may be required. The role may involve work in office, laboratory, supplier, integration, and mission-operations environments, and the engineer may need to adjust working hours to meet peak periods and surge requirements.

Requirements

Bachelor’s degree in Engineering.
Normally 5–10 years of related experience.
Demonstrated knowledge of fluid mechanics and thermodynamics.
Working knowledge of heat transfer, engineering materials, mechanical systems, structures, or machine design.
Experience analyzing propulsion, pressure, fluid, or thermal systems.
Experience supporting hardware development, testing, integration, certification, or operation.
Experience processing, analyzing, and interpreting engineering or test data.
Ability to evaluate requirements, technical drawings, analyses, test plans, test results, and verification evidence.
Ability to investigate technical issues and develop defensible engineering recommendations.
Ability to assess component-level issues in a broader system and vehicle context.
Strong written and verbal communication skills.
Ability to organize and coordinate multiple technical activities and priorities.
Ability to work independently while collaborating effectively with multidisciplinary teams.
Ability to communicate risks, uncertainties, and dissenting technical positions appropriately.
Willingness and ability to transition among branch assignments as organizational needs change.
Ability to work effectively in laboratory, supplier, integration, mission-operations, and office environments.
Ability and willingness to travel when required by the assignment.
Proof of U.S. citizenship or U.S. permanent residency may be required.
Must be able to complete a U.S. government background investigation.
Regular attendance in accordance with the established work schedule; ability to work outside the normal schedule and adjust the schedule to meet peak periods and surge requirements.

Experience working with configuration-management, work-order, issue-tracking, or document-control systems.
Experience developing small-spacecraft propulsion systems or rapid-turnaround flight hardware.
Experience leading technical tasks or mentoring early-career engineers.
License or certification may be required.

Responsibilities

Apply fluid mechanics, thermodynamics, heat transfer, materials, structures, and machine-design principles to propulsion and spacecraft pressure systems.
Independently perform or lead propulsion and pressure-system analyses.
Develop, review, and validate fluid-flow, pressure-system, thermodynamic, and thermal models.
Develop and maintain engineering analysis and data-processing tools using Python, MATLAB, or similar software.
Evaluate system architectures and lead or contribute to technical trade studies.
Establish technical assumptions, document analysis methods, and communicate results and limitations.
Assess component-to-system and system-to-vehicle technical effects.
Provide technical oversight of propulsion components, suppliers, and hardware-development activities.
Review designs, drawings, material selections, fabrication methods, assembly processes, and acceptance criteria.
Support or lead propulsion hardware development from concept through fabrication, assembly, test, integration, and operation.
Plan, coordinate, witness, or evaluate component- and system-level tests.
Review acceptance-test data, qualification reports, verification evidence, and flight-readiness documentation.
Evaluate test results and determine whether available evidence satisfies technical and program requirements.
Lead or support investigations of anomalies, nonconformances, and unexpected system behavior.
Develop technically defensible recommendations for issue disposition and risk mitigation.
Review and coordinate closure of variances, nonconformance reports, hazard reports, changes, waivers, reuse documentation, and certification action items.
Develop verification approaches and support formal certification of propulsion systems and flight hardware.
Assess pressure-system safety, cleanliness, contamination-control, and hardware-integration requirements.
Support propulsion-system integration with spacecraft, test vehicles, or small satellites.
Coordinate technical activities with NASA program and project offices, spacecraft organizations, suppliers, prime contractors, sub-tier contractors, and international partners.
Organize and track concurrent document reviews, technical issues, risks, and action items.
Delegate or coordinate reviews with appropriate hardware and technical points of contact.
Prepare and present technical status, risks, nonconformances, and recommendations to program stakeholders.
Participate in mission simulations, vehicle checkouts, propulsion console operations, and flight support.
Provide technical guidance and mentoring to less-experienced engineers.
Travel to supplier, test, integration, launch, or program locations when required.
Perform other duties as required.
