The Systems Engineer should have experience architecting systems, working across the Systems Engineering Lifecycle, a deep understanding of Systems Engineering principles, reverse engineering techniques, and the ability to work with complex software systems and the utilization of Digital Engineering/MBSE to accomplish program goals. The candidate will support STR's Systems Development Division to achieve architectural integrity and traceability from requirements analysis through system and software development and production system deployment. This position offers the opportunity to work with leading domain experts developing solutions to solve the most challenging national security problems. Our teams consist of motivated individuals with degrees in engineering, computer science, mathematics, physics, and data science. The ideal candidate will be experienced in Systems Engineering processes and techniques, Modeling and Simulation, software-based systems, Digital Engineering/MBSE and be excited about opportunities to grow and be a source of subject matter expertise across the organization. The Systems Engineer should have experience implementing a rigorous MBSE approach to develop DoD systems. New programs at STR will be looking to adopt agile approaches that incorporate model-based requirements management and traceability with software development. This position is well suited for a Systems Engineer with a software systems background who is interested in improving the state of the practice and demonstrating the advantages that MBSE can offer., * This position requires an Active DoD Top Secret Clearance with SCI eligibility, for which U.S. citizenship is needed by U.S. Government * BS, MS or PhD in Systems Engineering, Computer Science, Aerospace Engineering, Electrical Engineering, or a related technical field * Experience implementing open architectures and integrating with large scale software-intensive systems and platform systems * Strong ability to derive requirements from existing software and capture new customer requirements, and translate those into development tasks for software teams * Comfortable working in dynamic environments and adjusting to changing priorities * Minimum of 2 years work experience as a Systems Engineer or related field * Experience architecting systems using system modeling tools (SysML in Cameo) Even Better: * Domain expertise or familiarity with one or more of the following areas is highly desirable: + Sea, air, and space platforms, mission planning, and C2 systems + Sensor Resource Management + Electronic Warfare + Software deployment in cloud-based systems + Government Open System Architectures (UCI, OMS, COARPS) * 5+ years of experience in architecting systems using system modeling tools (SysML in Cameo) * Experience porting models/designs from SparxEA to Cameo * Experience in Java, Python, or object-oriented programming languages * Agile software development experience and/or certification ## Description * Utilize your Systems Engineering skillset as part of a tightly knit team to design, develop, implement, and deploy advanced software systems * Analyze, reverse-engineer, derive, and define requirements from ambiguous or incomplete software system implementations and codebases * Develop/generate documentation (e.g. Systems Requirements Document, SysML models) to capture requirements of new and existing systems * Perform gap analysis between derived requirements and current system capabilities to identify missing features or functionalities * Assist other technical contributors throughout the software lifecycle, from early prototypes to fully integrated systems * Implement MBSE approaches using SysML in Cameo * Work closely with domain experts and software development teams to realize program designs for a diverse set of applications, including: * + Distributed mission planning + Intelligence Surveillance Reconnaissance (ISR) management + Decision making support to human analysts/planners * This position is based in one of our offices but will take advantage of STR's flexible, hybrid environment: we anticipate that you could work remotely as much as 25% of the time * Any time work does not require use of STR's facilities, you are welcome to work remotely ## Related Videos - [Getting to Know Your Legacy (System) with AI-Driven Software Archeology](https://www.wearedevelopers.com/videos/1437-getting-to-know-your-legacy-system-with-ai-driven-software-archeology) - [Model Based Systems Engineering in an Agile Product Development Process](https://www.wearedevelopers.com/videos/68-model-based-systems-engineering-in-an-agile-product-development-process) - [Green Cloud Computing](https://www.wearedevelopers.com/videos/592-green-cloud-computing) - [Rethinking Intelligence: AI, Accessibility, and the Future of Inclusive Work - Artur Ortega](https://www.wearedevelopers.com/videos/1377-rethinking-intelligence-ai-accessibility-and-the-future-of-inclusive-work-artur-ortega) - [Why your codebase lies to AI?](https://www.wearedevelopers.com/videos/100281-why-your-codebase-lies-to-ai) - [WebAssembly: The Next Frontier of Cloud Computing](https://www.wearedevelopers.com/videos/972-webassembly-the-next-frontier-of-cloud-computing) ## Related Articles - [Is Software Engineering Over-Saturated?](https://www.wearedevelopers.com/magazine/418-is-software-engineering-over-saturated) - [Fully Remote Software Engineer Jobs](https://www.wearedevelopers.com/magazine/447-fully-remote-software-engineer-jobs) - [Highest Paying Tech Companies for Developers](https://www.wearedevelopers.com/magazine/220-highest-paying-tech-companies-for-developers) - [Best Countries for Software Engineers](https://www.wearedevelopers.com/magazine/267-best-countries-for-software-engineers) - [Where To Find Software Engineering Jobs](https://www.wearedevelopers.com/magazine/396-where-to-find-software-engineering-jobs) - [What is Software Engineering?](https://www.wearedevelopers.com/magazine/289-what-is-software-engineering)
