## Description

Shield AI is a venture-backed defense-tech company with the mission of protecting service members and civilians with intelligent systems.

As a Senior Flight Sciences Engineer focused on aeropropulsion, you will work across disciplines to enable the design, build, test, and flight of high performance unmanned aircraft.

## Responsibilities

- Support aeropropulsion design from the conceptual phase through flight, including inlet, duct, nozzle, and exhaust system definition

- Develop installed propulsion performance models, including inlet pressure recovery, distortion, spillage drag, nozzle performance, and installed thrust for Shield’s latest unmanned aircraft

- Analyze propulsion airframe integration effects, including thrust and drag bookkeeping, inlet and engine compatibility, and propulsion induced effects on aircraft performance and stability

- Contribute to flight sciences support through flight test data analysis, ducted fan and propulsion performance modeling, and correlation of models to test results

- Collaborate with propulsion, structures, flight test, and control systems engineers to ensure integrated, optimized, and safe aircraft performance

- Support wind tunnel, propulsion ground test, and flight test events, including test planning, instrumentation requirements, and data reduction

## Requirements

- You have a B.S. in Aerospace or Mechanical Engineering or equivalent

- You have 3 or more years of experience in aeropropulsion, propulsion integration, aerodynamics, aircraft performance, or another area of flight sciences

- You have a working understanding of gas turbine, ducted fan, or propeller performance and how installation effects influence aircraft performance

- You have a demonstrated record of working hard, being a trustworthy teammate, holding yourself and others to high standards, and being kind to others

## Preferred Qualifications

- Experience with computational fluid dynamics for inlet, nozzle, ducted fan, or internal flow analysis

- Experience with engine performance decks, cycle analysis tools such as NPSS, or propulsion system modeling

- Experience with inlet or propulsion wind tunnel testing, engine ground testing, or propulsion flight test

- Experience scripting or developing software in Python, MATLAB, or similar languages

- Experience with analysis of large data sets
