Tasks

The honest situation

Right now our tech team is tiny: one senior developer and our CTO. We are not a 50-person engineering org with layers of process. We are two people who ship things.

Our culture

We win and lose as a team. (But mostly we win ;-))

No bullshit. No politics. No endless meetings about meetings. We say what we think we fix whats broken we ship what matters.

We believe in a realistic workweek and work-life balance. Were not impressed by rockstar culture or overtime heroes. But when the roof is on fire we expect everyone to grab a bucket. Thats the deal.
