• Execute test plans for environmental, functional, and stress testing, following established procedures to meet aerospace standards (e.g., MIL-STD, DO-160).

• Identify and resolve integration issues related to electrical systems & mechanical systems, collaborating with cross-functional teams.

• Prepare technical documentation, including test procedures and reports, to support system validation and certification.

• Support ground test, hot-fire, integration, and flight test planning and execution

• Define propulsion system architectures, including engines, RATO units, ignition systems, fuel delivery, and controls

• Manage propulsion interfaces with airframe, avionics, power, controls, and safety systems

• Coordinate with suppliers and partners on propulsion components and qualification

• Support certification, compliance, and range safety requirements as applicable

• Work on multi-discipline teams with systems engineers, software developers, electrical engineers, and mechanical engineers to support cohesive system design and performance.

• Follow regulations and safety standards during integration and testing activities.

• Perform other duties as required.

• Proficiency in electrical design tools (e.g., Altium Designer, Eagle) and data analysis tools.

• Familiarity with test equipment (e.g., oscilloscopes, multimeters, signal generators).

• Strong understanding of electrical systems (power management, analog/digital circuits).

• Familiarity of RF principles (signal modulation, antenna performance) is a plus.

• Familiarity of Mechanical Design Software (SolidWorks, Fusion360) is a plus.

• Familiarity with aerospace/MIL standards.

• Strong problem-solving, communication, and teamwork skills

• Proficient knowledge of embedded systems or firmware development.

• Strong written and verbal communication skills, with the ability to clearly convey complex technical information to multidisciplinary teams, program management, and external stakeholders.

Education / Certifications

• Bachelor's Degree in Electrical Engineering, Mechanical Engineering, Aerospace Engineering, Systems Engineering, or a related field.

• Master’s degree in Electrical Engineering, Mechanical Engineering, Aerospace Engineering, Systems Engineering, or a related field desirable.

Experience

• 6+ years of relevant engineering experience supporting defense, aerospace, or related technical programs.

• Hands-on experience with circuit board design and/or benchtop electrical testing.

• Experience with UAS or drone systems through projects.

• Experience with integration and testing of subsystems into aerospace vehicles.

• Experience working with electrical systems, including circuit board design, benchtop electrical testing, and RF work
