Lead Software Engineer (Rust)

In this foundational role, you will act as our premier Rust expert, spearheading the strategic migration of our core execution engines, algorithms, and high-performance systems from C# to Rust. You will join a forward-thinking and collaborative environment where your technical vision shapes the future of our engineering stack.

Key Responsibilities

• Lead the strategic migration of legacy C# (.NET) codebases, execution engines, and complex algorithms into highly optimized, safe, and concurrent Rust applications.
• Design, develop, test, and maintain high-performance software components throughout the full software development lifecycle.
• Define all aspects of development for the new stack, establishing rigorous coding standards, workflows, and appropriate build and CI/CD environments.
• Provide technical guidance, expertise, and coaching to developers, playing a central role in upskilling the team and building internal Rust expertise from the ground up.
• Monitor team progress to ensure consistency with the initial architectural design, technical vision, and quality standards.
• Ensure all software strictly complies with requirements for quality, security, modifiability, and extensibility while leveraging modern AI-supporting tools to optimize efficiency.

Who You Are

You are a visionary technical leader and a passionate educator who thrives when navigating ambiguity and driving technological evolution. You possess deep engineering intuition, love tackling complex architectural challenges, and excel at empowering others to adopt new modern paradigms.

Qualifications & Skills

• Extensive professional experience in software engineering, with a proven track record of shipping and maintaining production‑grade Rust applications.
• Exceptional production‑level proficiency in Rust, including deep mastery of its memory safety guarantees, lifetimes, async runtimes (such as Tokio), concurrency models, and standard tooling (Cargo, Clippy).
• Strong foundational knowledge of C# and .NET architectures to effectively understand, reverse‑engineer, and transition existing codebases.
• Demonstrated architectural skills with a proven ability to design complex, scalable software systems and define clear technical visions.
• Exceptional talent for coaching, mentoring, and providing high‑level technical guidance to engineering teams while navigating ambiguity with a forward‑progress mindset.
• Excellent interpersonal and English communication skills, with the ability to articulate complex technical roadmaps and collaborate across cross‑functional spaces.
• A Bachelor’s degree in Computer Science, IT, or a related technical field (or equivalent practical experience).
