The qualified candidate will work with a diverse and talented team of engineers developing innovative and cost-effective systems that support a broad range of products and business areas across the lifecycle of a program. Applicants should possess the ability to communicate effectively and clearly present technical approaches and findings.

What you'll get to do:

Responsibilities may include Testing and Troubleshooting Line Replacement Units (LRU) of RF architecture, recommend data driven requirements threshold adjustments; perform subsystem analysis including hardware from RF to digits, support for performance testing, requirements verification, and more. Work is performed without appreciable direction and exercising considerable latitude in determining technical objectives of assignments

Experienced applicants will have at least a bachelor’s degree in science or other related technical degree or have equivalent experience testing and troubleshooting, integration, designing, developing and/or testing radio frequency (RF) and/or microwave antenna systems and/or related RF hardware. Candidates would have the ability to troubleshoot complex problems which require the regular use of ingenuity and creativity.

In addition, this candidate should have demonstrated technical ability/leadership and expertise in one or more of the following areas:

Wide Band Waveform Generator test and/or troubleshooting

Phase Noise test and/or troubleshooting techniques

RF and/or digital hardware test and/or troubleshooting

Troubleshot electronic equipment to the component level.

Integrated Receiver Exciter Assemblies (IREX)

Highly integrated subsystems including receiver exciter hardware

RF Performance Analysis

Computational Electromagnetics, Statistics

Subsystem Control Design

RF Measurements and Data Reduction

Integration and test of RF assemblies

Subsystem requirements (hardware and software) derivation, flow-down, and configuration

Comfortable creating test support applications and tools using MATLAB, python, etc.

Experience with Atlassian Tool Suite, Git

This position requires that you can contribute as an RF or Hardware Lead or are able to contribute to the needs of a HW\RF Team, within the AESA Hardware Subsystem Discipline. Candidate is preferred to have an engineering background that includes:

Familiarity with Antenna I&T\Analysis Subsystem parts (CCAs, front-end technology, Receiver-Exciter, phased array technology) and their capabilities

Familiarity with Antenna I&T\Analysis Subsystem metrics and requirements that are assessed (Gain, ERP, CPCR, Sensitivity, TOI, Noise Figure, various antenna subsystem health status, RF chain\paths)

Familiarity with Antenna I&T\Analysis Hardware testing environments:

Build-up stations of components\parts (Labs with program STE Test Racks)

Antenna Ranges (Near-Field, Compact Range, Far-Field, Spherical Near-Field)

Familiarity with AESA Sub-system Hardware flow processes

Pattern Analysis and modeling of AESA Subsystem hardware

ATP Testing flow (build, environmental screening, approval to move forward to NHA, TRRs, Post-Test Data reviews, Consent to Break, OK for Stores, OK to ship)

Understands the Design Process (PDR, DDR, CDR checklists and design gate deliverables)

Tools utilized for data processing\analysis (MATLAB, Python)

Documentation for Hardware (T-Specs, OTSAs, hardware drawings, ICDs, Set Selection Drawings)

Quality processes utilized in hardware anomaly cases (QNs, FRBs, MRBs, Engineering response to hardware failures in the ATP Test Flow, and Qualification phase)

These roles are contingent upon candidates having a current Active government Secret Clearance.

These roles are contingent upon Program Award.
