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 a 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.

How we calculate "similar"

No black box, no LLM guesswork: a deterministic score built from four normalized attributes. Here's this role's own peer group at different match levels, so you can see the mechanism, not just the result.

Every comparison starts from the same 100-point budget: 25 for working in the same function, 40 for the same therapeutic area, 20 for the same or adjacent seniority, 15 for the same country. A dimension we can't confirm on both sides contributes nothing, never a guess, never a free pass.

Unmatched or unknown dimensions score exactly the same: 0 points, never a partial guess. A role we know almost nothing about beyond its function bottoms out at 25%; it never inflates to 100% just because there's little to compare against. Seniority uses a defined ladder (Associate → Manager → Associate Director → Senior → Principal → Director → Senior Director → Executive/VP) so "Director" and "Senior Director" count as adjacent, but "Director" and "Executive/VP" do not.
