About the Role

We're seeking a Senior Full Stack Developer with a strong technical background in building embeddable and highly interactive digital experiences. You'll be part of a high-impact integration team for a digital banking platform that's scaling fast and building smarter ways to connect with third-party services and external user flows.

This role requires end-to-end thinking: from API design and backend logic to frontend widgets that power seamless, secure interactions across platforms.

What You'll Be Doing

• Design and implement APIs that support secure, scalable, and maintainable integrations

• Develop end-to-end solutions, taking ownership of both frontend and backend components

• Work closely with architects and product stakeholders to ensure secure authentication and data handling

• Implement communication strategies between platforms using postMessage, redirections, and secure cross-domain messaging

• Contribute to architectural decisions for improving scalability, reusability, and user experience

• (Nice to have) Build event-driven serverless functions (Azure Functions, AWS Lambda) to support real-time interactions and webhooks

What You Bring

• 5+ years of Full Stack development experience delivering production-grade web applications

• Strong experience in both frontend (React or Vue.js, HTML, CSS, JavaScript) and backend (Node.js, Python or similar) technologies

• Proven experience in integrating embeddable solutions and external systems via APIs

• Solid understanding of RESTful API design and implementation, including secure callback mechanisms and endpoint management

• Working knowledge of web security best practices: OAuth2, token-based authentication, CORS, data protection

• Familiarity with cross-origin communication patterns and secure redirections between platforms

• (Bonus) Experience with serverless architecture and event-based communication using Azure Functions or equivalent services
