Why this grade
This listing scored 22/100, which is an F. It lost the most ground on pay transparency.
- Remote clarity 15 / 15 Whether "remote" means anywhere, or is quietly restricted to one country.
- Description depth 14 / 20 How much the posting actually says about the work, measured in characters of real text.
- Corroboration 5 / 10 Whether more than one source carries this listing.
- Role specificity 3 / 10 Whether the listing is tagged well enough to tell what the role actually is.
- Freshness 0 / 15 How recently it was posted. Older postings are likelier to be filled or abandoned.
- Pay transparency 0 / 25 A published salary range, worth more than any other single factor because it is what a candidate cannot find out without applying.
-15 Ghost-job penalty — Deducted for signals that this posting may not be a real, currently-open role — staleness, repeated relisting, or talent-pool language.
Every figure above is arithmetic over the posting itself — its salary field, its text, its age, its tags and how many sources carry it. How the grades work →

Proton builds the privacy-first alternative to Big Tech: Mail, VPN, Drive, Pass, Calendar, and Lumo AI. We're profitable, have no VC control, and are majority owned by the nonprofit Proton Foundation, so no one can force a change in mission.
The Drive Foundation team builds the core SDK powering every Proton Drive client,C#, TypeScript, and Rust daily, with Swift and Kotlin bindings for mobile. It's foundational work: what you build here ships to every Drive client, and there's a crypto model revamp plus a Rust based next gen SDK on the roadmap.
Looking for someone with 5+ years of professional software experience and strong Rust expertise (ownership, concurrency), plus experience building libraries for client applications (web/mobile/desktop). Don't check every box but think you'd be a strong fit? We say apply anyway.
