About The Position

KBR is seeking a Junior Software Engineer to support the development, integration, and evaluation of software solutions for various RF systems in diverse operational and signal environments. This role involves supporting control, modeling, simulation, and testing of operationally relevant systems across research and applied DoD programs. The position requires a strong software foundation, interest in RF system fundamentals, and the ability to collaborate across system, algorithm, and integration boundaries with guidance from senior engineers. The software engineer will work closely with systems engineers and hardware teams to implement, test, and analyze position, navigation, and timing (PNT) capabilities in constructive, laboratory, and field environments. KBR's work focuses on engineering, logistics, operations, science, program management, mission IT, and cybersecurity solutions, offering innovative projects, a collaborative environment, and impactful work in designing and optimizing defense systems for national security and space defense.

• Familiarity with real-time or embedded systems
• Experience with HITL/SITL test architectures or laboratory integration
• Experience supporting DoD programs, laboratory R&D, or operational prototyping efforts

Responsibilities

• Develop, maintain, test, and document software for systems, simulations, and performance analysis environments
• Implement algorithms and models under guidance, including measurement modeling, error characterization, and estimator behavior under non-ideal conditions
• Implement and integrate algorithms within software frameworks
• Integrate software with hardware- and software-in-the-loop (HITL and SITL) and digital twin environments
• Develop interfaces between software components and external systems
• Support test planning, execution, and analysis for PNT-focused experiments, demonstrations, and evaluations
• Collaborate with systems engineers to align system requirements with software designs and implementations
• Document software implementations, interfaces, and test results to support technical reviews and deliverables
