Senior Software Engineer at Checkr

This role is ideal for a Senior Full Stack Engineer who thrives in "zero-to-one" environments. You should have at least 6 years of experience and a background as a founder or an early employee at a fast-paced startup. The team is looking for an "A-player" who can handle the technical demands of Ruby on Rails and React while also acting as a product owner who isn't afraid of ambiguity. The standout feature of this position is the "startup within a startup" dynamic—you get the speed and autonomy of the Checkr Trust lab backed by the massive resources and stability of a Forbes Cloud 100 company. The compensation is highly competitive ($185k–$218k base), complemented by premium benefits like 100% medical coverage, a $25k fertility/adoption stipend, and daily catered lunches in the San Francisco office. **You might be a good fit if you:** * Have experience building scalable APIs and asynchronous architectures for millions of users. * Enjoy a hybrid schedule (3 days/week in SF) and want to influence product direction directly. * Prefer shipping MVPs and running experiments over long, rigid development cycles. * Are comfortable working across the full stack with Ruby on Rails and React.
