Northrop Grumman Mission Systems Manufacturing Operations Test Engineering Team in Baltimore, MD seeks a Digital & Power / RF Test Engineer – Level 3 or Level 4.

This career opportunity is a great fit for self-motivated, proactive individuals who want to assume ownership of the performance and delivery of Northrop Grumman's diverse suite of digital, RF and power hardware. Our engineers work in a high exposure, fast paced, and exciting environment that involves “hands on” technical challenges, problem solving, and inter-department collaborations. If you thrive on solving problems and want different challenges each day, please read on!

RF / Digital Test Engineer – Level 3 or Level 4

We are seeking an experienced test engineer with strong foundations in digital electronics, power electronics, and RF to support production testing and troubleshooting of complex mixed‑signal hardware. In this role, you will work on both transmit‑side and receive‑side assemblies in a manufacturing environment, combining automated test execution, hands‑on bench debug, and data analysis to improve First Time Through Test Yield (FTTTY), Scrap, Rework, and Repair (SRR), performance, and reliability.

This position may be filled at either the Level 3 or Level 4 engineer level depending on the qualifications, experience, and demonstrated capabilities of the selected candidate.

What You’ll Get to Do

Execute and troubleshoot automated test procedures covering

• DC power‑on and current checks
• Programming and JTAG / boundary‑scan tests
• Digital bus and control interface tests
• RF gain, noise figure, and intermodulation measurements
• Channel isolation, BIT (built‑in test) functions, and filter rejection

Perform hands‑on debugging using

• Oscilloscopes to verify clocks, resets, and digital control signals
• Spectrum analyzers and power meters to measure RF power, spurious, harmonics, and phase noise
• Vector network analyzers to measure magnitude and phase of rf signals.
• DMMs and other tools to validate supply rails, regulator outputs, and device health
• Troubleshoot end‑to‑end RF and IF chains using schematics and block diagrams:
• Identify issues in filters, amplifiers, switches, mixers, attenuators, and protection devices
• Compare measured performance against test specifications and limits
• Track down excessive insertion loss, gain errors, or unexpected spurious responses

Work with digital and embedded aspects of the design

Support JTAG‑based programming and device verification

Verify that control buses, configuration registers, and BIT indicators behave as expected

Apply structured troubleshooting methods

• Use golden/reference units, A/B comparisons, and systematic measurements to isolate suspect hardware
• Perform targeted component swaps and select‑in‑test (SIT) adjustments to bring units within specification
• Document findings, QNs, and corrective actions clearly and consistently
• Collaborate closely with design engineering, manufacturing engineering, and test technicians:
• Provide data‑driven input on failure trends and root cause
• Help refine test limits, procedures, and troubleshooting flows
• Mentor technicians in interpreting automated test results and performing safe, effective bench debug
• The successful candidate will be comfortable moving between digital, power, and RF problems; can read and reason from detailed schematics and block diagrams; and is disciplined about data, documentation, and communication.

Basic Qualifications — Level 3

Bachelor’s degree in Electrical Engineering or related STEM field and a minimum of 5 years of relevant experience; or

Master’s degree in Electrical Engineering or related STEM field and a minimum of 3 years of relevant experience

Experience in a lab or production environment with

• Oscilloscopes, spectrum analyzers, power meters, vector network analyzers, signal generators, and DC power supplies
• Debugging and characterizing mixed‑signal or RF hardware (board or module level)
• Experience reading and use of schematics and block diagrams to localize hardware failures.
• Experience executing and debugging automated test procedures (e.g., power‑on, functional, RF performance, and BIT tests).
• Experience with basic RF concepts (gain, noise figure, spurious, harmonics, filters) and analog/digital circuitry.
• A current/active DoD Secret Security Clearance.
• U.S. citizenship.

Basic Qualifications — Level 4

Bachelor’s degree in Electrical Engineering or related STEM field and a minimum of 8 years of relevant experience; or

Master’s degree in Electrical Engineering or related STEM field and a minimum of 6 years of relevant experience

Experience in a lab or production environment with

• Oscilloscopes, spectrum analyzers, power meters, vector network analyzers, signal generators, and DC power supplies
• Debugging and characterizing mixed‑signal or RF hardware (board or module level)
• Experience reading and use of schematics and block diagrams to localize hardware failures.
• Experience executing and debugging automated test procedures (e.g., power‑on, functional, RF performance, and BIT tests).
• Experience with basic RF concepts (gain, noise figure, spurious, harmonics, filters) and analog/digital circuitry.
• A current/active DoD Secret Security Clearance.
• U.S. citizenship.
• Preferred Qualifications (applies to both Level 3 and Level 4)
• Experience with automated test equipment (ATE) platforms and test automation software.
• Experience troubleshooting RF front ends or transceiver chains (filters, LNAs, mixers, attenuators, switch matrices, etc.).
• Experience with JTAG/boundary‑scan tools and digital interfaces (e.g., SPI, I²C, LVDS, or similar).
• Experience with built‑in test (BIT) concepts and designing or maintaining production test limits.
• Experience with LabWindows/CVI, C/C++, Python, or similar languages for automated test development.
• Experience with minimal direction, manage multiple units/tests in parallel, and communicate technical findings to cross‑functional teams.
