Demonstrated ability to solve difficult hardware and software integration challenges is required.
Ability to work independently and collaboratively with minimal guidance and within rigid timelines is required.
Ability to interact with data suppliers, coworkers, and customers at disparate locations is required.
Ability to communicate complex technical issues and provide comprehensive written, oral, or digital products, including organized documents and technical writing, is required.
Analytical skills and ability to multitask across a primary project and one or two ancillary projects are required.

Responsibilities

Develop RF sensor models, algorithms, and associated simulation software, and perform trade-space analysis to assess and verify system characteristics and capabilities.
Develop complex antenna element and array models, assess and verify antenna design and capabilities, and integrate antenna models into larger system models, algorithms, and simulations.
Document software and hardware characteristics and changes to simulation environments; design test architectures and plans; design and execute experiments and tests; collect and analyze data; and generate reports.
Integrate models into complex simulation architectures, including engagement-level and theater-level simulations, hardware-in-the-loop architectures, and AFSIM-based mission-level simulation environments.
Support development, testing, and refinement of subsystem and system models within AFSIM to improve scenario fidelity and mission-effectiveness evaluations.

Desired Qualifications

Professional training in modeling and simulation related to space, missile, or aircraft system performance and dynamics is preferred.
Strong antenna pattern recognition and specific experience designing and analyzing complex antenna elements and arrays, especially interactions and interference within antenna systems, are preferred.
Experience with at least one additional programming or software-development language, such as C, C++, or Python, is preferred.
Familiarity and specific experience with ECHO, CST, FEKO, HFSS, or another electromagnetic simulation software package are preferred.
Familiarity with TMAP is preferred.
Familiarity with the Department of Defense and the United States Intelligence Community is preferred.
Experience developing mathematical models of aerospace vehicle dynamics, guidance, navigation, and control components and algorithms is preferred.
Basic understanding of system component integration and ability to model entire systems or individual components, such as sensors, guidance, navigation and control, propulsion, and aerodynamics, at varying levels of detail are preferred.
Hands-on experience applying subsystem or system models within AFSIM for scenario analysis or mission behavior modeling is highly desirable.

About the Company

Aether Aerospace

Hybrid hydrogen-electric eVTOL for personal aviation

Aether Aerospace is developing a personal eVTOL aircraft called Project Aether that uses a hybrid hydrogen-electric propulsion system and aims to achieve FAA MOSAIC certification. The aircraft uses batteries for hovering and hydrogen fuel cells for cruise, with the cells recharging the batteries in flight, to offer more than 250 miles of range. It features a tandem tilt-wing with eight ducted fans, fly-by-wire controls, and a whole-aircraft ballistic parachute for safety. The company targets two markets: individual owners who can store the aircraft in a two-car garage for about $195,000, and flight centers that would buy fleets of 10–20 aircraft to rent to Sport Pilots, supported by hydrogen fuel, maintenance, and a booking platform, with the goal of bringing a certificated, on-demand personal air vehicle to market and scaling through fleet-based services.
