What you need
Requirements
- Experience in Python . Our core application backend and data pipeline services are built with Python and Django
- While frontend / React may not be your primary focus, you’re not afraid to dive in when needed
- Very strong attention to detail. When you work with numbers this is a non-negotiable - it’s not enough to be 99% right.
You'll thrive here if
- You're a Dog. You've been underestimated, gone through struggle, and never stopped running. You have a chip on your shoulder and enormous drive. You look at Stripe, Deel, and Flexport all punting on compliance and think: good, that means the opportunity is ours. Hunger beats pedigree.
