Grade C

Why this grade This listing scored 64/100, which is a C. It lost the most ground on pay transparency. See the breakdown

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.
Pay transparency 12 / 25 A published salary range, worth more than any other single factor because it is what a candidate cannot find out without applying.
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.

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 →

Hi HN, I'm the founder of Proofline. We're building an infrastructure-aware AI code reviewer that catches deployment failures before they reach production. Think of it as a type checker for your cloud infrastructure. We analyze code changes against Terraform, live cloud environments, and deployment evidence rather than just reading diffs.
We're hiring a hands-on Staff / Principal Engineer to help us build. You'll own core SaaS architecture, cloud integrations, developer tools, and product delivery, with a path toward engineering leadership.
Stack: Rust, Go, PostgreSQL, React/TypeScript, Terraform, AWS, GCP.
We're looking for someone with 10+ years of hands-on infrastructure engineering experience, deep SaaS and cloud expertise, extensive use of AI coding agents, and a track record of shipping end to end.
Remote globally, flexible hours, regular Berlin visits required. Salary: €120k-€200k depending on experience and location, plus meaningful founding equity. No visa sponsorship.
To apply, ship a small feature PR to one of our open-source developer tools and email [email protected] with the link. If you have 10+ years of relevant experience and an established online presence showcasing your technical work, you can skip the PR and share your best work with us instead.
