Company mission
To provide a state-of-the-art upgrade for payment providers, shielding them from the current antiquated legacy technology still in use today.
Role
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:
- 5+ years of experience
- Strong understanding of frontend fundamentals:
- HTML, CSS, JavaScript
- Responsive design and accessibility
- Component-based frontend frameworks and modern patterns, including state management and reactive rendering
- Design system usage and maintenance
- Styled components vs utility-first CSS (e.g., Tailwind)
- Client-side vs server-side rendering considerations
- Browser runtime
- Authentication and authorization (OAuth2, session management, token handling)
- Professional experience with and willingness to work with React and TypeScript
- Understanding of backend fundamentals:
- Database persistence (SQL vs NoSQL)
- HTTP and REST APIs
- Authentication and authorization (JWT, OAuth2)
- Performance and reliability considerations (latency, rate limiting, caching)
- Professional experience working on interfaces with a backend component
- Experience with automated testing and tooling to analyze user behavior and monitor web application performance
- Experience with AWS or other cloud-native environments
What the job involves
- 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
Our take
Silverflow is addressing the longstanding challenge of outdated backend processing systems in the payment industry. While notable disruptors like Adyen, Stripe and PayPal have transformed the front end, offering merchants user-friendly and innovative solutions, the backend infrastructure has largely remained rooted in technology from the past. This gap prompted Silverflow's founders to envision a new approach.
Silverflow's solution is to offer offering a singular API to connect seamlessly with card networks, reducing both the cost and complexity of payments processing for its clients. The platform, which is designed for ease-of-use and enriched with valuable data, allows both legacy and new players alike to innovate their processing approach for more secure and efficient payments.
Strong funding reflects the confidence in Silverflow's vision, and the potential impact of its solution. This financial support is instrumental in the company's ability to pursue its global expansion plans, building on its successful entry into the US and APAC markets in 2023. Overall, Silverflow is well-positioned to further disrupt the payment processing market and establish itself as a category leader.
