Software Engineer, Online
FlatpayJobbeskrivelse
About The Job
Flatpay has become one of the fastest-growing payment companies by helping merchants accept payments in-store. Now we're taking the next step.
Online is one of Flatpay's newest and most strategic engineering domains. We're building the products and platforms that enable merchants to accept payments online and grow their businesses in the digital economy.
As a Software Engineer, you'll help build and launch new products, contribute to technical discussions and decisions, and scale solutions as adoption grows across new markets.
This is a unique opportunity to join at an early stage.
While
Flatpay already serves merchants at scale, our online platform is still in its early stages. You'll have the opportunity to help launch new solutions, shape how the platform evolves as adoption grows, and learn directly from customers along the way.
If you enjoy building products from the ground up, working close to customers, and seeing your work evolve from first launch to large-scale adoption, you'll have the opportunity to make a significant impact in a domain that will play an important role in Flatpay's future growth.

- Experience building and operating production systems
- Comfortable working across modern backend and cloud technologies
- Strong understanding of software engineering fundamentals
- Curious, pragmatic, and eager to learn
