Senior Backend Developer (Integration Team)
We’re building the next generation of digital payments, where integrating payment terminals and cash register systems is as seamless and reliable as possible. Our team ensures partners and customers can focus on their business — while we handle the complexity of secure, scalable integrations. Join us to shape a future where payments just work.
Role Overview
This is a senior backend development role with room for architectural input. You will:
- Write, test, and deploy production-grade code in TypeScript on Node.js
- Help design APIs and think through system architecture with scalability, resilience, and security in mind
- Contribute in designing and implementing secure, cloud-native applications that make integrations smooth and reliable (DevOPS mindset)
- Contribute to our event-driven architecture, experimenting and refining as we go
- Collaborate closely with teammates in a cross-functional, forward-thinking environment
- Take part in operating and continuously improving the services we run
- We’re the integration team: our mission is to remove friction between payment terminals, cash register systems, and the broader payment infrastructure.
- Security and reliability are at the heart of everything we do — when integrations fail, business stops. That responsibility shapes how we work: as a collaborative, skilled team focused on solving real-world challenges with clarity and precision.
- We operate with autonomy and trust, encouraging proactive thinking, experimentation, and learning.
- We value sharing ideas, asking questions, and refactoring when needed. AI tools like GitHub Copilot are part of our workflow, helping us focus on creative and critical problem solving.
- Our hybrid model gives the team freedom to decide the right rituals and routines. We maintain a healthy balance of deep focus, collaboration, and sustainable pace.
- This role is based in Espoo, Finland, with hybrid work as the default. Candidates should be located within commuting distance of the office.
