Organizational Description:
The Advanced Test Systems Engineering Center (ATSEC) is an organization within the Systems Test Directorate comprised of five departments and an engineering population of approximately 550 people, and over $350M per year of delivered products. The ATSEC organization has the responsibility to grow and sustain the Systems Engineering competencies throughout all test activities, and to make test more affordable, credible, agile, and robust.

Within ATSEC, the Hardware in the Loop (HWIL) Radio Frequency (RF) and Electro-Optical (EO) Departments have the responsibility to provide, develop, and maintain engineering development stations that operate real-time and closed-loop with the weapon’s hardware and software. These test environments include Software Evaluation Stations (SWES), Computer in the Loop (CILs), Processor in the Loop (PILs), and Hardware in the Loop (HIL) facilities, which are used to perform the development of weapon embedded software, qualification of embedded software (FQT), integration of weapon’s hardware and software, and verification of the weapon’s systems performance. The HWIL departments support all Raytheon Missiles Systems (RMS) products, including new business initiatives, maintenance contracts, Internal Research and Development (IRADs), and Engineering Capital projects. The successful candidate will support both HWIL departments from within the HWIL EO department. Specific responsibilities of both HWIL departments include:

  • Development of test environment’s requirements, interface requirements, design, and documentation.
  • Design and implementation of hardware, firmware and software to perform real-time and closed-loop operation with the weapon’s hardware and software.
  • Preparation and release of the environment’s Technical Data Package (TDP), and verification of requirements, acceptance test and delivery of the equipment (ATP/TRB).
  • Development and execution of technology roadmaps to insert new technologies in these engineering test environments.

Job Description:
Experienced level engineer position for an individual with educational and professional experience in the design, development and integration of mechanical systems.

The individual will be responsible for the design, fabrication, integration, and documentation of mechanical systems for HWIL Test Environments. Development work includes, but is not limited to design and analysis of antenna array structures, missile fixtures, and Test Environment rack designs.

The individual is expected to work in a team environment, on diverse projects and will contribute to the development of all stages of product development for HWIL Test Environments. The candidate will be responsible for managing mechanical tasks and coordinating with other functional areas to ensure the quality and reliability of HWIL products. The individual will be responsible for technical drawings, application of geometric dimensioning and tolerancing as well as the release process for getting the final drawings approved for procurement and fabrication. They will be required to provide development support throughout the Test Environment lifecycle, from initial concept through product acceptance, and product maintenance which will include preparation of technical analysis reports, and presenting in design reviews.

The individual is expected to work in accordance with the Systems Test directives and One Page Process to perform product design, development, implementation and maintenance.
