Backend Engineer for Climate Advocacy Organisation

About Bank.Green

Since the Paris Agreement, global banks have poured a staggering $6.9t into the fossil fuel industry. At Bank.Green, our mission is to lower this vast carbon footprint via technology and consumer action. We empower bank customers with the tools and insights they need to influence their banks towards sustainable lending, or switch to greener alternatives. To date, our bank-checking tool has been used over 500,000 times by bank customers worldwide, while we have shifted a at least $35,000,000 towards banks who are financing a greener future.

Through transparency, engagement, and innovation, we aim to redefine the role of banks in the fight against climate change.
