In rapidly changing global security environments, Northrop Grumman brings informed insights and software-secure technology to enable strategic planning. We’re looking for innovators who can help us keep building on our wide portfolio of secure, affordable, integrated, and multi-domain systems and technologies that fuel those missions. By joining in our shared mission, we’ll support yours of expanding your personal network and developing skills, whether you are new to the field, or an industry thought leader. At Northrop Grumman, you’ll have the resources, support, and team to do some of the best work of your career. We are looking for you to join our team as a Principal/ Senior Principal CAL Systems Engineer based out of Linthicum, MD and will require 100% on-site work. This requestion may be filled as a Principal CAL Systems Engineer or a Senior Principal CAL Systems Engineer What You’ll get to Do: This role may comprise developing calibration algorithms, 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. Roles and Responsibilities: 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 lifecycle. Assess the effectiveness of modeling and simulations supporting BIT/Cal performance, and use results to improve calibration strategies and test approaches. Develop an in‑depth understanding of sensor hardware capabilities and limitations to inform calibration design and integration decisions. Verify embedded implementations of BIT and Cal modes, ensuring they align with requirements and modeling assumptions. Produce publication‑quality technical documentation, including Cal concepts, test plans, procedures, and verification
