You're not just executing on designs; you actively provide input that shapes new hardware iterations and regularly interface with engineers to make critical decisions for the Aeon R program. Having successfully developed and refined processes for our initial development engines, the team is now focused on producing flight engines at rate for Terran R's aggressive launch manifest., * Own the AeonR integrated assembly from design release to integration to shipment. This will include developing the build process to meet production targets and reduce build issues. * Develop processes and specs that directly impact the production rate of AeonR engines. * Support production as needed to deliver engines by resolving build issues, receiving and implementing technician feedback, supporting BOM updates and build checkouts. * Support work center development by considering assembly operations, tooling and capital equipment requirements, and rate targets. You will also support engine work center development across sites. * Author test procedures and act as test conductor to verify as-installed hardware health and build integrity. * Assist with developing the business tools and processes that will be used to manufacture the first launch vehicle. In parallel, help to define and pilot the long-term ERP, MES, and QMS solutions that will enable high-quality, efficient vehicle manufacturing.
