We are looking to augment our team working with the Naval Research Laboratory to develop a shared technical framework for M&S of Navy combat systems. Cutlass provides technical leadership to systems engineering, integration, and operation of the M&S: we are empowered and proactive. Work is in an R&D setting with freedom to forward new ideas and bring them into reality. Innovation is encouraged. Results directly impact ships and maritime systems to help protect sailors and improve our Navy. We offer flexible hours, telecommuting options, excellent benefits, and zero bureaucracy. This position is for an on-site Senior Software Engineer at the Naval Research Laboratory in Washington D.C., to support development, integration, and execution of a series of simulations used for system-of-systems analysis. Things you'll be working on: * Design, develop, and maintain simulation models that represent real world maritime systems. * Design and develop software to advance a high-performance computing framework that controls the interaction and automation of simulations. * Define and implement the exchange of data and events between simulations while maintaining interoperability and portability across computing platforms, operating systems, and communications systems. * Design, develop, test, debug and maintain application programming interfaces for external / 3rd-party systems or software. * Design and implement prototype software tools for controlling simulations, extracting/reducing data, visualization of data, and system-of-systems analysis. ## Related Videos - [Improving quality with Agentic AI with Rovo Dev and Xray](https://www.wearedevelopers.com/videos/2005-improving-quality-with-agentic-ai-with-rovo-dev-and-xray) - [Docker network without Docker](https://www.wearedevelopers.com/videos/1418-docker-network-without-docker) - [From DevOps to Scaled DevOps: How We’re Rebuilding Continuous Delivery as a Platform](https://www.wearedevelopers.com/videos/100018-from-devops-to-scaled-devops-how-we-re-rebuilding-continuous-delivery-as-a-platform) - [Security Pitfalls for Software Engineers](https://www.wearedevelopers.com/videos/726-security-pitfalls-for-software-engineers) - [#90DaysOfDevOps - The DevOps Learning Journey](https://www.wearedevelopers.com/videos/548-90daysofdevops-the-devops-learning-journey) - [Collaboration Quantified: Lessons from Open Source Developer Networks](https://www.wearedevelopers.com/videos/1422-collaboration-quantified-lessons-from-open-source-developer-networks) ## Related Articles - [Software Engineer Career: Things You Should Know](https://www.wearedevelopers.com/magazine/143-software-engineer-career-things-you-should-know) - [Best Countries for Software Engineers](https://www.wearedevelopers.com/magazine/267-best-countries-for-software-engineers) - [What is Software Engineering?](https://www.wearedevelopers.com/magazine/289-what-is-software-engineering) - [How We Built a Worry-Free System That Runs for 10+ Years – And What We’d Do Again](https://www.wearedevelopers.com/magazine/751-how-we-built-a-worry-free-system-that-runs-for-10-years-and-what-we-d-do-again) - [Is Software Engineering Over-Saturated?](https://www.wearedevelopers.com/magazine/418-is-software-engineering-over-saturated) - [Is Software Engineering Hard?](https://www.wearedevelopers.com/magazine/448-is-software-engineering-hard)
