Propulsion Test Engineer - IDACS

About Frontier Aerospace Corporation

At Frontier we’re advancing the next generation of in-space propulsion systems—high-performance, reliable hypergolic thrusters that enable precision orbital maneuvering, station-keeping, and deep-space exploration. Our team thrives at the intersection of hands-on engineering, rapid testing, and flight reliability.

We are currently looking for a Propulsion Test Engineer with a focus on Instrumentation and Data Acquisition & Control Systems (IDACS) to join our propulsion test operations team. This role bridges hardware, software, and test operations, ensuring our test stands deliver accurate data and safe, reliable performance. While working with cross‑functional engineering teams, this position ensures that all IDACS and test system implementations meet Frontier’s technical, quality, and operational objectives.

The Propulsion Test Engineer – IDACS is responsible for the design, development, integration, and operation of Instrumentation, Data Acquisition, and Control Systems used across Frontier’s propulsion test assets. This includes specifying sensors and instrumentation, implementing data acquisition and control hardware/software, and ensuring accurate, reliable, and safe operation of all test systems supporting hypergolic propulsion testing.

This role focuses on building and maintaining high‑fidelity test capabilities by defining system performance requirements, integrating hardware and software interfaces, and verifying that all instrumentation and control subsystems function seamlessly with the broader test environment. The engineer will support testing activities by configuring, operating, and troubleshooting IDACS and related subsystems such as operator user interfaces, electrical terminals, I/O modules, network systems, and effector control systems.

As a Propulsion Test Engineer with Frontier Aerospace, you will contribute to the development and documentation of concepts of operations (Con Ops), test requirements, and verification procedures for new or modified test infrastructure involving instrumentation and data acquisition. The role also involves performing analyses related to safety, reliability, maintainability, and testability, ensuring all systems meet operational and safety standards.

• Develop and maintain IDACS systems for propulsion test stands, including sensor selection, signal conditioning, wiring, and data acquisition architecture.
• Integrate control systems for fluid and operator subsystems (valves, regulators, flow control, and safety interlocks).
• Design and execute propulsion test campaigns, from cold‑flow to hot‑fire, ensuring data quality and system safety.
• Generate and maintain all definition documentation in support of IDACS equipment.
• Develop and manage engineering tools, as needed in support of test operations.
• Conduct test operations in the control room as needed.
• Own sub‑systems within the test environment—such as operator user interfaces, feed systems, or effector control systems — driving design improvements and maintenance.
• Troubleshoot and calibrate instrumentation (pressure, temperature, thrust, flow, etc.) to ensure high‑fidelity measurement.
• Read, interpret, and analyze technical data.
• Prepare and support Test Readiness Reviews and Test Data Reviews.
• Monitor and maintain tracking all IDACS equipment, including scheduling maintenance, scheduling calibration cycles, and submitting requests for new equipment when required.
• Collaborate with propulsion engineers to define test requirements, execute test plans, and interpret results.
• Implement and maintain automated data logging and control scripts, working closely with software and controls teams.
• Ensure safe operations in a hazardous test environment, including hypergolic propellants, pressurized systems, and high‑voltage electronics.
• Regular and comprehensive communication to the Propulsion Test Manager/Propulsion Test IPT Lead.

• Bachelor’s degree in Mechanical, Electrical, Aerospace, or Systems Engineering, or equivalent hands‑on experience.
• 2+ years of experience in propulsion testing, data acquisition…
