RF Calibration Test Engineer

Standard Job Description

Lockheed Martin is a global security and aerospace company that employs approximately 114,000 people worldwide and is principally engaged in the research, design, development, manufacture, integration, and sustainment of advanced technology systems, products, and services. Lockheed Martin Missiles and Fire Control (MFC) is one of four Lockheed Martin business areas.

We are growing rapidly and seeking to hire a Systems Integration & Test Engineer for our Grand Prairie, TX site.

The RF Calibration Test Engineer will plan and execute developmental calibration testing of RF sensors in anechoic chambers and outdoor test ranges. Under general direction, the engineer will independently develop calibration test methods and procedures, configure RF measurement systems, analyze data, and assess measurement quality. This role applies comprehensive RF/microwave, antenna, propagation, and radar signal processing knowledge to complex calibration issues and collaborates with design and systems teams to produce repeatable, traceable calibration results.

Core Responsibilities

• Translate assigned sensor calibration requirements into test methods, procedures, test configurations, and data quality criteria.

• Plan and coordinate chamber and outdoor range activities, including equipment readiness, reference measurements, and test article configuration.

• Configure and operate vector network analyzers, spectrum analyzers, signal generators, power meters, and associated RF test equipment.

• Develop and execute sensor calibration measurements, characterize test-path effects, and apply approved calibration and correction methods.

• Evaluate repeatability, measurement uncertainty, and environmental or setup influences on calibration results.

• Develop MATLAB, Python, or comparable tools for instrument automation, data reduction, analysis, and visualization.

• Investigate complex discrepancies involving RF hardware, antenna response, signal processing, propagation, and test setup effects.

• Prepare calibration data products and technical reports, document assumptions and limitations, and coordinate review with sensor design and systems engineers.

• Maintain traceability of reference standards, instrument calibration status, as-run configurations, and analysis software versions.

Basic Qualifications

• Bachelor's degree in Electrical, Electronics Engineering, Physics, or a related STEM field, or equivalent combination of relevant education and experience.

• 3+ years of related experience in RF testing, antenna measurements, sensor calibration, or RF/microwave engineering.

• Strong knowledge of RF/microwave principles, antenna theory, radar signal processing, and propagation.

• Proficiency with RF test equipment, including vector network analyzers and spectrum analyzers, and familiarity with calibration standards.

• Experience developing test procedures, evaluating RF measurement data, and preparing technical reports.

• Experience using MATLAB, Python, or similar tools for data analysis and test automation.

• Ability to independently resolve complex measurement problems under general direction and work effectively with multidisciplinary teams.

• Interim Clearance is needed to start, therefore you must be a US Citizen.

Desired Skills

• Experience performing RF sensor or antenna calibration in anechoic chambers and outdoor ranges.

• Experience with RF path characterization, amplitude/phase measurements, antenna pattern measurements, and measurement uncertainty analysis.

• Familiarity with reference standards, calibration traceability, and evaluation of chamber or range measurement limitations.

• Experience developing reusable instrument-control software and automated calibration data-processing workflows.

• Experience correlating chamber and outdoor range results and supporting root-cause analysis of inconsistent measurements.
