Who is Silverflow?
Silverflow is a payment processing company designed for today's payment needs and fit for the future.
A first true, cloud-native solution with a single API to the card networks that replaces legacy systems. One platform with one connection that reduces cost and complexity, is easy to use, and data-rich.

Today, Silverflow is a diverse, international team of 80+ colleagues representing over 30 nationalities. We value collaboration, ownership, and curiosity, and we are proud of the culture we are building together. With ambitious growth plans to reach 120 team members over the next two years, we are creating opportunities for people who want to make an impact and grow alongside the company.
What You'll Do
We are looking for a full-stack developer who will take our client-facing applications to the next level by building new features and evolving or revamping existing interfaces — both in layout and under the hood — and make a meaningful impact in a primarily backend-driven organization.
Develop and improve client-facing (internal and external) application features and interfaces.
Ensure production reliability through automated testing and monitoring.
Own features end-to-end, making informed, cross-functional technical trade-offs.
Promote frontend best practices and mentor engineers to boost developer experience.
Partner with Product Managers and UX Designers to implement vision into high-quality UIs.
Who You Are
You have some experience on the backend but your expertise and passion lie in the frontend. You are comfortable working with and evolving a design system, and understand different approaches for building reusable components. You have strong affinity with UX, and care about building accessible, maintainable user interfaces.
You value automated testing, observability, and monitoring to ensure reliability in production. You take ownership of features end-to-end, collaborating across the stack when needed. You have experience with designing frontend features dependent on backend systems and can make informed trade-offs.
You enjoy spreading frontend best practices, improving developer experience, and mentoring other engineers. You’ll be a great fit if you have:

-
HTML, CSS, JavaScript
-
Responsive design and accessibility
