## Description

At Northrop Grumman, you'll have the resources, support, and team to do some of the best work of your career.We are seeking Staff CAL Systems Engineers to join our Built-in-Test (BIT) / Calibration Systems Engineering team in Linthicum, MD. This role is 100% on-site and primarily focused on calibration (Cal) modes for advanced RF sensor systems.What You'll get to Do:Cal Mode Integration & Verification EngineerThis role focuses on taking established Cal modes that have not been fully vetted, then driving them to operational readiness and full requirements verification.Take existing Cal modes and systematically vet, test, and mature them for operational use.Partner with other mode teams to incorporate and tailor Cal modes that support their specific performance needs.Analyze Cal performance, identify deficiencies or edge cases, and define updates to tactical code for correction and optimization.Provide clear technical guidance to a software engineering team that will implement fixes and
enhancements in the tactical code base.Tie Cal mode design, test results, and analysis artifacts directly to requirements verification, ensuring full traceability from requirements through implementation and test.Support system integration & test (I&T), focusing on calibration behavior in integrated environments and helping close performance verification for sensor modes.Cal Algorithm Development & Tactical SW Support EngineerThis role focuses on the "other side of the V," developing calibration algorithms and supporting software engineers through tactical code generation and implementation.Develop, refine, and document calibration algorithms that compensate for hardware and system-level errors in RF sensors.Use modeling, simulation, and analysis tools (e.g., MATLAB, Python) to design and evaluate Cal algorithms against system performance requirements.Define algorithm interfaces, data flows, and constraints to enable robust embedded/tactical implementations.Collaborate
closely with software engineering teams to translate Cal algorithms into tactical code (primarily C/C++, with supporting MATLAB/Python scripts), providing ongoing technical direction and clarification.Participate in code reviews and integration activities to ensure that the tactical implementation correctly reflects algorithm intent and performance assumptions.Support lab and field testing to validate algorithm behavior and confirm that implemented Cal modes meet performance and stability requirements.As a Staff BIT/CAL Systems Engineer, regardless of role focus, you will:Confirm that calibrations correctly capture and compensate for hardware and system errors so that sensor performance levels meet or exceed requirements.Derive and refine BIT and calibration requirements from system-level performance objectives and concepts of operation.Design and evolve calibration and diagnostic modes, including how they are invoked, executed, monitored, and maintained across the system
