Job DescriptionAbout the RoleDelta Research is looking for a Modeling & Simulation Software Developer to work on a small engineering team building simulation tools for missile defense analysis.The primary work is in Object-Oriented Modern Fortran - new features, bug fixes, and refactoring on a large, established simulation codebase. The rest of the time goes toward supporting infrastructure in Python, JavaScript, and Rust: data management, visualization, pre- and post-processing, and whatever else the software needs to support the engineers and analysts using it. Developers manage their own workload and priorities day-to-day, with guidance from the team on what matters most at a given time.What the team needs most is someone who can mostly own a piece of work from start to finish.
