Job Description

The Role

As a Senior Software Engineer in our Exchange domain, you won't just be writing features; you will be architecting the future of our platform. In 2026, our primary mission is foundational modernization. We are leading the charge in modernizing our architecture; shifting from legacy systems and transitioning our ecosystem from .NET toward a unified Java/Spring stack.

The Team

The Exchange domain is composed of talented engineers distributed in multiple countries across Europe. We are building the central services that power the business for one of our biggest products. We believe in strong collaboration and team work, high quality engineering, and providing the best possible experience for our customers.

What You'll Do

Collaborate on this modernization journey: Design and implement patterns for legacy displacement to move domains out of our monolith with zero downtime.
Bridge Tech Stacks: Build new services and help transition others from .NET to Spring while navigating and contributing to other codebases.
Product Collaboration: Partner with product managers to question and form requirements, understand the "Why", and help shape a roadmap that balances technical debt with new value.
Global Collaboration: Communicate effectively across timezones. Your written documentation and async communication will be the glue for our distributed team.
Master Observability: Use Grafana and modern tracing to monitor system health, ensuring our backend-heavy domain remains performant and reliable.
Drive AI Efficiency: Leverage Agentic programming tools (like Claude Code) to accelerate refactoring and development workflows. Use it to deal with obvious problems and focus on the complex ones.

Who You Are

Backend Expert: You have deep experience in backend systems and feel comfortable switching between programming languages. Practical experience with .NET and Java are a plus.
Systems Thinker: You are comfortable with event-driven systems, and have a proven track record of breaking down monoliths and managing system migrations.
Quality Obsessed: You believe that code without a robust test suite (Unit, Integration, E2E) isn't finished.
Pragmatic & Curious: You have a strong product mindset. You don't just take tickets; you seek to understand the business impact of your architectural choices.
Observability Advocate: You don't wait for a crash to know there's a problem; you build systems that tell you how they're performing.

Working at Cint

Remote-First: Work from anywhere where Cint operates with a setup that supports your best work.
High Autonomy: We trust our engineers to make sound decisions and own their work end to end.
Global Impact: Your work powers a marketplace used by millions of people worldwide
