About Volt

When Volt launched in 2019, we recognised how open banking has the power to transform how businesses, wherever they happen to be, receive payments from their customers. So, we set about building an open payments gateway that enables merchants across the globe to receive direct, account-to-account payments – in real time.

Now, on the back of a record-breaking $23.5 million Series A funding round, we’re building an all-star team to achieve our goal of ‘real-time payments everywhere’.

About the project

Checkout is our interface for payment requests processing. This is where the payer selects their bank and provides all the necessary details to initialize the payment. You’ll be joining a team of 6 fantastic people led by Wojciech Grabias: 4 Frontend Developers, 1 PO and 1 QA. As a Frontend Software Engineer, you’ll work across the user-facing development lifecycle, building leading-edge disruptive financial technology solutions using Svelte, NodeJS, TypeScript and CSS.

  • We’re building new, game-changing tech that’s evolving at lightning speed. It’s energising to be part of,
  • We champion ‘extreme ownership’ – being not just the owner of your own tasks, but a key member of a team united by, and accountable for, common goals,
  • During the week we mostly work remotely but for those who prefer to be in the office we arranged coworking spaces in Warsaw (Business Link Astoria) and Cracow (Chillispaces),
