Hey, I'm Stan

Software Developer & Creator of Top Jobs Today

I'm a software developer, and over time I realized I cared mostly about roles at big tech companies - not just whatever happened to show up on LinkedIn or generic job boards. But those sources weren't enough - some roles were delayed, or never posted at all.

So I built this website to solve that. It scrapes fresh job postings directly from official company sites, figures out what kind of roles they really are, and sends them as email alerts - simple, fast, and focused.

Hope it makes your search easier too. Wishing you the best of luck - and I'm really glad you're here!
