Why this grade
This listing scored 52/100, which is a D. It lost the most ground on pay transparency.
- Freshness 15 / 15 How recently it was posted. Older postings are likelier to be filled or abandoned.
- 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.
- 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.
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 →

We're an early-stage UK company building a mobile application, funded by its founder (just me), which is why the scope below is deliberately narrow.
I'm looking for an applied cryptographer to review a protocol specification before it ships. It is small and specific: three messages, two parties, signature-based, using hardware-backed keys on both iOS and Android. It uses standard primitives only (ECDSA over P-256, SHA-256) and invents no new cryptography; the question is how they are combined. The specification is written and frozen, with test vectors and the generator that produces them.
What I want is a competent second opinion on whether it is sound: six specific questions answered in writing. Not an open-ended audit or a penetration test. The person I'm looking for has either published on protocol security or reviews protocols professionally; being good with crypto libraries isn't quite the same thing.
One piece of contract work, not a role. Under a short mutual NDA.
Email [email protected] by Sunday 4 October with a short summary of the protocol analysis you've done, and I'll send scope, timing and what I'd need from you.
