## About the Role

* Bachelor's degree with 12 years of experience, Master's degree with 10 years of experience or Ph.D. with 8 years of experience in Science, Technology, Engineering, Mathematics, or related technical fields; an additional 4 years of experience may be considered in lieu of a degree
 * U.S Citizenship is required
 * A current/active U.S. Government Secret Clearance
 * Ability to obtain Special Program Access (SAP).
 * Experience with MATLAB for data analysis and/or algorithm development.
 * Domain experience in sensor simulations for RF sensors.
 * Experience with integration and test of RADAR, SIGINT, or EW systems.
 * Experience programming in C/C++.

Preferred Qualifications

 * Advanced degree in a STEM or related technical field.
 * Experience with Python for data analysis, test automation, or algorithm prototyping.
 * Demonstrated experience with calibration modes, requirements verification, algorithm development, or system integration for RF or sensor systems.
 * Active DoD Top Secret clearance or higher.

## Description

This 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 Engineer

This 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 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 evidence.
 * Support factory test, system integration & test, and field support activities with a focus on calibration behavior and system performance closure
