We are seeking a Systems Engineer with deep software expertise to join our Electronic Warfare system modeling team. In this role, you will design, build, and maintain high-fidelity simulation frameworks that run actual production EW software against emulated hardware and synthetic RF environments. You will work at the intersection of systems engineering, signal processing, and software development - contributing to a digital-twin-style capability that supports algorithm development, performance analysis, and iterative validation. Key Responsibilities • Develop and maintain containerized simulation pipelines that execute production EW software modules against simulated hardware and environmental inputs • Build and extend RF simulation components including platform kinematics, sensor/effector models, propagation physics, and event-driven interaction frameworks • Transition and integrate signal processing algorithms (e.g., from MATLAB or legacy codebases) into microservice-based simulation architectures • Implement CI/CD pipelines supporting automated testing, simulation regression, and artifact generation • Develop hardware/firmware emulation layers at appropriate fidelity levels (probabilistic and detailed signal path) • Contribute to Monte Carlo and parameter sweep workflows for performance envelope analysis • Collaborate with algorithm developers and systems engineers to validate simulation outputs against analytical references and measured data You will be working on a majority greenfield modeling capability at the core of EW system development, not primarily maintaining legacy tooling, but building the infrastructure that future algorithm development and system validation will depend on. The technical problems span low-level systems programming, physics simulation, and distributed software architecture. Required Skills and Education • BS in Computer Science, Electrical Engineering, or related field • Strong proficiency in Rust and/or Python for performance-critical systems development • Experience with containerization technologies (Docker, Docker Compose) • Familiarity with microservice architectures and inter-process communication (e.g., Protocol Buffers, gRPC, NATS/ZeroMQ) • Experience with CI/CD tooling (GitLab CI/CD or equivalent) • Strong fundamentals in algorithms and systems programming Preferred Skills and Education • Experience with signal processing concepts or RF systems (e.g., radar, EW, communications) • Familiarity with embedded systems, hardware interfaces, or SWIL/HWIL testing environments • Exposure to distributed systems concepts (consensus algorithms, sharded architectures) • Experience with Foreign Function Interfaces (FFIs) for cross-language integration • Background in mathematics, including linear algebra and probability #ECSSE Benefits Information Employee Benefits: At BAE Systems, we support our employees in all aspects of their life, including their health and financial well-being. Regular employees scheduled to work 20+ hours per week are offered: health, dental, and vision insurance; health savings accounts; a 401(k) savings plan; disability coverage; and life and accident insurance. We also have an employee assistance program, a legal plan, and other perks including discounts on things like home, auto, and pet insurance. Our leave programs include paid time off, paid holidays, as well as other types of leave, including paid parental, military, bereavement, and any applicable federal and state sick leave. Employees may participate in the company recognition program to receive monetary or non-monetary recognition awards. Other incentives may be available based on position level and/or job specifics. Intern Benefits: Temporary employees generally are not eligible for BAE Systems benefits, but can elect to participate in the 401(k) savings plan. Temporary employees working 20+ hours per week are eligible for medical benefits, the employee assistance program, and business travel accident insurance. Please note: Some benefits may be different for union employees that are governed by a collective bargaining agreement (CBA) or for positions covered by a wage law called the McNamara-O'Hara Service Contract Act (SCA).
