Senior🎓
Top SchoolAustin Mccartney is a Senior Systems Software Engineer with 11 years of experience building high-performance C++ and Python systems, currently at NVIDIA and active as an open-source maintainer and consultant. He has modernized legacy scientific codebases and tooling at national labs, delivering up to 5x runtime improvements and portable build systems across Linux, macOS, and Windows. His open-source footprint includes contributions to influential C++ projects such as HPX (iterator concepts for parallelism), immer (immutable data structures), and trompeloeil (robust compilation-error testing), where he’s improved both library correctness and QA automation. Comfortable across systems, CI, and template metaprogramming, he blends low-level performance tuning with pragmatic developer tooling and documentation. Based in Ocala, Florida, he brings a nuclear engineering background and a knack for turning physics-driven requirements into clean, testable software.
