Senior Rust Developer

Spyrosoft is looking for a Senior Rust Developer to join the Qt Bridge for Rust team. This role focuses on designing, implementing, and hardening a library that allows developers to build Qt Quick and QML user interfaces with a pure-Rust backend, bridging the gap between Rust and C++.

Key responsibilities

• Contribute production-quality Rust and C++ code, tests, and documentation to the QtBridge repository.
• Work on complex object-model, memory-safety, type-system, and macro-related challenges.
• Design and stabilize a public library API, focusing on semver, breaking-change management, and deprecation policies.
• Conduct threat analysis and security reviews of the Rust/C++ FFI surface.
• Maintain build stability across Linux, MSVC, and macOS platforms.

Requirements

• Senior-level Rust experience in production, including deep knowledge of ownership, borrowing, Pin, and lifetime-parameterized APIs.
• Proven experience with Rust and C++ FFI, ideally using the cxx crate to design safe wrappers.
• Expertise in procedural macro development with a focus on clear compile-error diagnostics.
• Strong background in cross-platform Rust build engineering and library API design.
• Working knowledge of Qt 6 and C++17, sufficient to read and modify the bridge's C++ layer.
• Commitment to high-quality testing, clean code standards, and documented safety arguments.

What we offer

• Opportunity to work on a specialized, high-impact library within a professional team.
• Fully remote work environment with a structured, review-heavy development process.
• Engagement in a long-term project with a focus on technical excellence and library stability.
