✅Green flags
You’ve built many things before — whether it succeeded or failed, you learned from it.
You think like a founder. You don’t just solve tickets—you find problems and fix them.
Speed > perfection. We move absurdly fast. Ship. Be scrapy. Learn. Repeat.
You care more about user issues than technical issues. Everybody participate in user calls at Tengo.
No babysitting. If you need detailed specs and guardrails, this isn’t for you. We hire people who figure things out while building it.
Smile every morning because work is fun and colleagues are fun.
Feedback is a gift, there is so much to learn from great peers.
Transparency isn’t optional. Sharing wins, mistakes, and half-baked ideas without hiding or ego. It build trust and foster real collaboration
You’re cool with getting your hands dirty on a topic that isn’t sexy (you might even find tenders are fun someday)
