Propulsion Development Engineer

About The Role

As a Development Engineer on the Propulsion team, you will be responsible for advancing engine hardware through rapid, test-driven iteration. You will operate at the intersection of hardware execution and data analysis, owning engine test campaigns and translating results into actionable engineering improvements. This role requires strong hands-on capability, analytical rigor, and the ability to move quickly between test operations, data interpretation, and hardware problem-solving. You will play a critical role in increasing engine development velocity and reliability.

Responsibilities

• Own development engine test campaigns from planning through execution and post-test analysis
• Define, author, and refine engine test plans, procedures, and setpoints aligned with program objectives
• Support and make decisions during live test operations, including hot-fire and subsystem testing
• Identify, diagnose, and resolve test-related engine issues across hardware, instrumentation, and procedures
• Standardize and improve test data review, reduction, and reporting processes
• Develop Python-based tools for data processing, visualization, and automated analysis
• Translate test data into clear engineering insights, including performance characterization and root cause analysis
• Drive post-test reviews and ensure actionable outcomes are captured and executed
• Participate in hands-on engine build, integration, and test setup activities
• Author and maintain development engine work instructions, test procedures, and technical documentation
• Generate, track, and resolve engineering issues through ticketing systems
• Collaborate cross-functionally with design, manufacturing, avionics, and test teams to resolve system-level challenges
• Ensure proper sensor selection, instrumentation setup, and data integrity during test campaigns
• Contribute to continuous improvement of test infrastructure, tooling, and development processes

Requirements

• Bachelor’s degree in Mechanical Engineering, Aerospace Engineering, or a related discipline
• Hands-on experience with hardware build, integration, or test operations
• Experience developing or executing engineering test plans and procedures
• Proficiency in Python for data analysis and automation
• Strong understanding of sensors, instrumentation, and diagnostic techniques

Preferred Skills And Qualifications

• Experience with liquid rocket engines or air-breathing propulsion systems
• Familiarity with high-speed data acquisition and telemetry systems
• Background in thermofluids, combustion, or turbomachinery
• Experience operating in fast-paced, iterative hardware development environments
• Demonstrated ownership of hardware or test systems through multiple development cycles
