Our employees are not only part of history, they're making history.

That same spirit of innovation continues within Northrop Grumman's Mission Systems sector, where we develop mission-enabling technologies for global security. Our Engineering and Sciences (E&S) organization brings together multidisciplinary technical expertise to research, develop, design, integrate, and sustain advanced systems and technologies.

From our Woodland Hills campus in the greater Los Angeles area, our engineering teams support programs across Navigation and Cockpit Systems (NACS) and Emerging Capabilities Development (ECD), spanning established products and next-generation research and development.

Together, we advance precision sensing, positioning, navigation, and timing (PNT) capabilities that strengthen mission effectiveness and provide a decisive advantage to the warfighter.

We are seeking a Principal / Sr. Principal Electronics Engineer to join our engineering team. In this role, you will design, develop, integrate, and verify precision analog and mixed-signal electronics for advanced PNT applications, including resilient navigation in GPS-denied or contested environments.

These electronics support inertial sensors, including gyroscopes and accelerometers, as well as inertial measurement units (IMUs), inertial navigation systems (INS), and other precision sensing and measurement instrumentation.

Achieving the accuracy, stability, and low-noise performance these technologies demand requires rigorous circuit design, quantitative analysis, and hands-on laboratory verification.

You'll collaborate with mechanical and systems engineers, digital hardware and embedded firmware engineers, controls specialists, and experts in sensor physics and precision instrumentation to translate demanding performance requirements into reliable and manufacturable electronic hardware.

The role offers opportunities to take technical ownership from initial design through debugging, verified performance, and next-generation sensor-interface development.

What You'll Do

• Design precision analog and mixed-signal electronic circuits for advanced sensing and electromechanical instrumentation.
• Develop sensor excitation, drive, detection, pickoff, signal-conditioning, and actuation electronics for precision measurement and closed-loop control of electromechanical devices.
• Design and optimize low-noise analog front ends, precision measurement circuits, data acquisition interfaces, and analog-to-digital and digital-to-analog signal chains.
• Develop electronic noise and error budgets using circuit-level modeling, spectral analysis, and quantitative evaluation of noise contributions to instrument performance.
• Deliver detailed electronic designs from circuit analysis, modeling, simulation, schematic capture, and component selection through engineering reviews, design verification, controlled release, and revision management of schematics and supporting documentation.
• Drive circuit card assembly (CCA) development through board bring-up, hands-on hardware integration, and testing while verifying hardware performance under representative environmental conditions to support qualification and production readiness.
• Characterize and debug electronic hardware through hands-on laboratory testing, correlate analytical predictions and circuit simulations with measured performance, and verify the effectiveness of design improvements.
• Own complex electronic hardware anomalies from initial discrepancy through systematic bench troubleshooting, root-cause analysis, corrective action, and verified technical resolution.
• Collaborate with sensor physicists, controls specialists, and FPGA/digital engineers to evaluate transducer interfaces, feedback-loop behavior, noise mechanisms, and their effects on sensor performance.
• Communicate technical findings, design tradeoffs, and engineering recommendations through design reviews, technical reports, and discussions with program stakeholders.
• Share circuit-design methods, test procedures, failure-analysis findings, and lessons learned through documentation, peer reviews, and mentoring; seek feedback from experienced specialists to expand technical capability.
• (Sr. Principal) Lead complex precision-electronics development while remaining directly involved in laboratory investigations and hardware verification; establish circuit architectures, guide technical reviews, and mentor engineers toward independent technical ownership.

This position requires full-time on-site work at our Woodland Hills, CA facility and follows a 9/80 work schedule, with every other Friday off.

This position may be filled at either the Principal or Sr. Principal level based on the qualifications listed below.
