Priorities may shift quickly. Oftentimes, we're tackling very ambiguous problems that don't have clear-cut answers. At times, you'll need to build things in a day: we live and breathe a value called "Calculated Speed". We don't have structured management (yet!). We expect more than 9 to 5 - raw hours make an impact at our current stage. We trust each team member to create a flexible work schedule that allows them to be most productive while accommodating other priorities outside of work. We also strongly encourage time off to recharge the batteries: in addition to unlimited PTO, we've implemented a minimum 20 days vacation policy.
