Shine exists to help freelancers and small business owners reclaim the joy of working for themselves.

Running a business shouldn't mean drowning in financial admin - it should be inspiring and rewarding. Our app brings banking, invoicing, accounting and admin together in one place, so entrepreneurs can focus on what matters most: growing their business and enjoying the freedom of working for themselves.

We're a multicultural team of over 400 people across France, Germany, Denmark and the Netherlands. By bringing together leading European fintechs like Shine, Kontist and Tellow, we've built a single, intuitive platform designed for simplicity, speed and accuracy - backed by local, award-winning support.

Your hiring experience matters

Just as we respect our customers' time, we respect yours. Your experience with Shine should feel simple, transparent and genuinely supportive.

If this sounds like somewhere you want to grow, we'd love to hear from you.

👀 Engineering at Shine

At Shine, our 150 engineers design scalable, reliable, and user-centric solutions through a modern architecture that drives our growth. Organized into specialized tribes, they collaborate in cross-functional squads—including an Engineering Manager, a Product Manager, a Product Designer, and Software Engineers—to foster innovation and excellence.

Our structure maximizes impact and ownership:

• Product teams develop core features for key business domains (invoicing, banking, accounting).
• Platform teams manage infrastructure and core services (Cloud, DevOps, Core APIs, developer tools).
• Data team builds data pipelines for engineering, modeling, and analytics.

Within our Banking tribe, the Banking Core team plays a central role. The team builds and maintains the foundational systems that power Shine’ banking services. It is now expanding to strengthen our core infrastructure for scaling Shine across markets, with a strong focus on building and evolving our card and payment products.

Our stack includes TypeScript, Node.js, React, PubSub, Docker, Terraform, GitHub Actions, and GCP—structured in microservices and event-driven architectures.

📋 Your Role as a Senior Software Engineer

By joining the Banking Core team, you will contribute to shaping the foundation of Shine’ banking services. Your mission: help design, build, and scale our next-generation payment systems while ensuring resilience and reliability of our existing core infrastructure.

This role requires strong experience in TypeScript/Node.js backend environments.

Your responsibilities will include:

• Building distributed, event-driven systems that power our payment flows and ledger logic.
• Strengthening and maintaining existing banking core services to ensure performance and stability.
• Writing clean, maintainable, and well-tested code using best engineering practices (DDD, TDD, clean architecture).
• Collaborating closely with your squad (Engineering Manager, Product Manager, and fellow engineers) and contributing to design and code reviews.
• Participating in architectural discussions and proposing scalable technical solutions.
• Sharing knowledge and mentoring peers—particularly important for our senior engineers.
• Helping improve team rituals, demos, and feedback loops to keep collaboration meaningful in a remote-first setup.

📍 Job located in Paris, Berlin or Amsterdam, with possibility of two remote working days per week

• Comfortable working in cross-functional squads with engineers, product managers, and designers.
• Strong communication skills and curiosity for the product and customer experience.
• Experience in banking, payments, or regulated environments is a plus.
• Fluent in English; French is a strong advantage.
