Job Description:
Job Description Job Description AST SpaceMobile is building the
first and only global cellular broadband network in space to
operate directly with standard, unmodified mobile devices based on
our extensive IP and patent portfolio and designed for both
commercial and government applications. Our engineers and space
scientists are on a mission to eliminate the connectivity gaps
faced by today's five billion mobile subscribers and finally bring
broadband to the billions who remain unconnected. Position Summary
The Harness Manufacturing Engineer is responsible for developing,
optimizing, and supporting the production of electrical harnesses
and cable assemblies for Low Earth Orbit (LEO) satellite platforms.
This role ensures harnesses are designed, manufactured, and tested
to meet aerospace standards and mission requirements, while
improving quality, repeatability, and production efficiency. Key
Responsibilities Manufacturing Engineering Support: Develop and
maintain harness assembly processes, work instructions, and
manufacturing documentation (routers, travelers, and assembly
drawings). Support design-to-production handoffs by reviewing
harness design schematics and layouts for manufacturability and
reliability. Define and select tooling, equipment, and materials
required for harness production. Drive improvements in harness
routing, termination, and installation practices. Production
Oversight: Provide on-the-floor support to manufacturing
technicians during harness assembly, integration, and
troubleshooting. Establish and optimize assembly sequences and jigs
to ensure repeatable, high-quality harness fabrication. Perform
root cause analysis and implement corrective/preventive actions for
nonconformances. Testing and Quality Assurance: Develop and
implement testing protocols using automated harness testers (e.g.,
CIRRIS or similar systems). Ensure all assemblies comply with
IPC/WHMA-A-620 and NASA/ESA workmanship standards. Review and
approve first article inspections (FAIs) and ensure compliance with
aerospace quality requirements. Process Improvement &
Documentation: Lead continuous improvement initiatives to increase
production efficiency and reduce cost. Maintain configuration
management of harness designs, tooling, and process documentation.
Collaborate with design engineers, quality teams, and supply chain
to ensure smooth production flow. Qualifications Bachelor's degree
in Electrical, Mechanical, Aerospace Engineering, or related field;
or equivalent technical experience. 3 years of experience in
harness or cable assembly manufacturing for aerospace, defense, or
satellite applications. Strong understanding of harness design
principles, electrical schematics, and 3D CAD tools (e.g., CATIA,
Creo, SolidWorks). Familiarity with industry standards:
IPC/WHMA-A-620, ECSS-Q-ST-70, NASA-STD-8739.4. Hands-on experience
with crimping, soldering, wire dressing, and connectorization.
Experience with automated harness testers (CIRRIS, DIT-MCO, etc.).
Strong problem-solving skills, attention to detail, and ability to
work in a fast-paced, high-reliability production environment.
Preferred Skills Experience in satellite or spacecraft harness
design and integration. Knowledge of harness routing and design in
3D modeling software. Understanding of aerospace material selection
(wires, connectors, backshells, shielding, and sleeving). Lean
manufacturing or Six Sigma certification. AST SpaceMobile is an
