We now show two types of job listings

Same commitment to real jobs. More opportunities for you. Here's how it works.

✓ Verified Employer-Verified Posts

These jobs were posted directly to RJRP by the employer. The company has been verified through our multi-step process. This is our gold standard — the employer is real, the job is real, and you can apply with confidence.

✓ 100% employer verified
🔍 Observed Market-Observed Roles

These roles were detected through employer hiring systems like Workday. They haven't been verified by the employer directly, so we score each one using our Hiring Activity Score — an algorithm that analyzes freshness, specificity, company hiring patterns, and more to estimate whether the role is actively being filled.

📊 Only high-scoring listings are shown

Our promise hasn't changed. We will never show you a listing we can't stand behind. Market-observed roles must pass our scoring threshold before they appear on RJRP. Anything that looks like a ghost job, a talent pipeline, or a dead listing gets filtered out — you'll never see it.
