This role requires sound working knowledge of fluid dynamics, thermodynamics, and heat transfer to develop and analyze propulsion components. The ideal candidate for this role will also be able to support and interpret hot-fire test data to recommend design modification of sub-assemblies. Agile follows a fast-paced culture and the ideal candidate will have the opportunity for growth and increased sphere of influence as part their career progression. Critical skillsets being sought after are ability to work autonomously, prioritize competing tasks, and take initiative in a high-cadence environment.

Responsibilities:

• Leads the design of propulsion components and sub-assemblies (e.g., injectors, combustion chambers, valve interfaces) with minimal supervision.
• Performs component and subsystem-level trade studies to balance performance, manufacturability, and cost.
• Supports test planning, execution, and data reduction for component-level test campaigns.
• Conducts independent root-cause investigation for design or test anomalies and proposes corrective actions.
• Develops and reviews engineering drawings and tolerance stacks for sub-assemblies; contributes to design review packages (e.g., PDR/CDR-level content) for assigned components.
• Supports planning for component-level work packages, contributing scope and schedule input for small initiatives.
• Provides design and technical guidance to junior engineer teammates.
• Develops manufacturing planning for propulsion sub-assemblies, ensuring designs are producible and testable.
