Who are Yapily

Why we exist, and where we’re headed

Our Mission: Redefining how the world interacts with value.

Our Vision: A world without financial friction

Our Purpose: To empower everyone to access and move value

Yapily is an open banking infrastructure platform solving a fundamental problem in financial services today: access. Historically, card networks have monopolised the global movement of money, and banks have monopolised the ownership of, and access to, financial data.

Yapily was founded to challenge these structures and create a global open economy that works for everyone. We exist behind the scenes, securely connecting companies - from growth to enterprise - to thousands of banks worldwide, enabling them to access data and initiate payments through the power of open banking.

We are seeking an exceptional Principal Front End Developer to architect our front-end ecosystem and guide our team into an AI-native future. This role combines hands-on development with strategic leadership, driving innovation in our user interfaces while mentoring a talented front-end team in adopting AI-native workflows. The ideal candidate will shape our front-end architecture, liaise closely with the principal developer team (including backend and product) to ensure architectural alignment, and guide the company in elevating UI development standards. As our Principal Front End Developer, you will champion agentic coding workflows, influence the product roadmap, and ensure our UI components—the primary interface for our clients—are built with scalability, security, and velocity at the forefront.

Beyond writing code, you'll act as a bridge between engineering and product, using data, user feedback, and industry best practices to refine and optimize our web applications. Aside from our API, these UI components are the main interaction our clients and their customers have with Yapily, making your role critical to our success.

The ideal candidate should have expert level skills in frontend development, as well as strong proficiency in backend development and APIs. Excellent development experience with modern Javascript frameworks, backend technologies and testing tools are necessary. Our technical stack includes React, Playwright, Vite, Node.js, Java, Spring. Experience in aggregation businesses or open banking is also highly advantageous.

Our company has been recognised as a leader in the Open Banking industry, with numerous accolades for our innovative products and services.

Join our vibrant and collaborative work environment, where ideas are nurtured and creativity thrives. We believe in fostering a culture of continuous learning and growth.

With a global presence, you have the opportunity to work with talented professionals around the world, expanding your horizons and making a difference.

We also understand the importance of work life balance and offer flexible working arrangements, ensuring you thrive both professionally and personally.

We also invest in our employees growth and development offering a training allowance for every employee, as well as mentorship opportunities.
