We’re looking for a fully remote (EU / Ukraine only) Rust / C++ Developer to help us build safe, high-performance software that works seamlessly with existing C++ libraries. You’ll write idiomatic Rust wrappers, and make sure the result is robust, maintainable, and well tested.You’ll be building for real-world use at scale, where reliability, maintainability, and efficiency matter just as much as clean code. The work spans low-level interoperability to automated build pipelines, so you’ll need to be comfortable switching between deep technical problem-solving and higher-level design thinking.We move quickly, trust each other to deliver, and give you space to own your work from day one.TasksIn this role, you will:Design and implement Rust interfaces to existing C++ libraries.Write safe, idiomatic Rust code that integrates cleanly with C++ APIs.Integrate your work into CMake-based build systems and GitHub Actions CI/CD pipelines.Develop automated tests and examples to demonstrate correct usage.Collaborate closely with maintainers and other developers to ensure compatibility across the codebase.Document your work so others can build on it easily.RequirementsEssential:Strong experience with Rust, including FFI (Foreign Function Interface) and writing adapters for compiled codebases.Solid C++ skills, including understanding of varied APIs and build tooling.Experience with CMake-based projects.Fluency with Git, GitHub, and GitHub Actions.Comfortable working in UNIX environments; exposure to high-performance computing environments a plus.A sense of urgency: you’re a responsive communicator who works quickly and to the highest standardsThe ability to thrive in ambiguity, tackling problems that might not be well defined and that may not have obvious solutionsA burning desire to improve the current state of government software contracting.Nice to have:Experience building software for government and public sector organisationsExperience working on data-heavy visualisation or monitoring toolsExperience integrating Rust into existing large-scale software stacks.Prior work on software for scientific or data-intensive applications.
