Responsibilities

Own hardware from design release through build, test, and delivery for engine or vehicle systems, taking full responsibility for execution readiness and product quality across subassemblies and integrated systems

Develop and release detailed build flows, work instructions, and test procedures to enable repeatable, high-quality execution across first builds and maturing programs

Support first article builds in a fast-paced environment, focusing on manufacturability, repeatability, and quality, while developing scalable processes that enable a smooth ramp to higher production rates

Provide hands-on floor support during build and test, resolving issues in real time, incorporating technician feedback, and driving continuous improvement across hardware flow and process discipline

Coordinate across design, supply chain, production, and test teams to ensure part readiness, tooling availability, schedule alignment, and smooth handoffs between build stages

Contribute to the development of long-term manufacturing systems and infrastructure, including tooling strategies, ERP/MES workflows, and production documentation standards

Required

Degree in engineering or a related technical field, with 2+ years of hands-on experience building and testing hardware in a manufacturing or integration environment

Skilled at investigating hardware issues, resolving non-conformances, and driving root cause analysis with corrective actions implemented effectively

Familiar with general assembly and test procedures, including tolerance stack-up analysis, structural proof testing, and pressurized leak checks

Comfortable interfacing across design, manufacturing, supply chain, and test teams to ensure hardware quality and schedule alignment

Self-starter who can define and roll out new processes from scratch, working collaboratively with technicians, engineers, and external vendors

Proficient in GD&T, CAD, and basic design or test analysis, with experience in at least two of the following: LOX cleanliness, leak checking, sensor checkouts, tube bending, tool design, crane operations, or subassembly builds

Preferred

Experience supporting new aerospace product introduction or transitioning hardware from prototype to production, especially in a high-rate or scaling environment

Experience directly authoring and executing test procedures, including acting as a test conductor for integrated system verification

Familiarity with hazardous operations, fluid system safety, or test execution involving pressurized or high-risk environments

Experience in a fast-paced and lean environment, including direct vendor engagement, tool development, or leading a small team through an ambiguous build or test effort
