Senior Rust / C++ Developer

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.

In 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.

Essential:

• 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 standards


• The ability to thrive in ambiguity, tackling problems that might not be well defined and that may not have obvious solutions


• A burning desire to improve the current state of government software contracting.

Nice to have:

• Experience building software for government and public sector organisations


• Experience working on data-heavy visualisation or monitoring tools


• Experience integrating Rust into existing large-scale software stacks.


• Prior work on software for scientific or data-intensive applications.
