About Scorechain

Scorechain is a Luxembourg-based company specialized in blockchain analytics and compliance solutions. We build tools that help financial institutions, crypto businesses and regulators assess risk, stay compliant, and fight fraud in the digital asset space.

We are growing our engineering team in Belval and are looking for a Full Stack Developer who loves the TypeScript ecosystem and is eager to work on impactful, production-grade products.

Your Role

As a Full Stack Developer at Scorechain, you will:

• Design, develop and maintain web applications using TypeScript, Node.js, and React.
• Implement robust REST APIs and backend services.
• Work with SQL and NoSQL databases to model, query, and tune data access.
• Collaborate with product, data, and devops teams to deliver features from concept to production.
• Contribute to code quality through reviews, testing, and clean architecture.
• Occasionally dive into C++ code to adjust or extend existing components (with the help of LLMs/tools when it makes sense).
• Participate in designing and improving event-driven architectures and data pipelines (Kafka and similar technologies).
• Help improve our internal tooling, developer experience, and engineering best practices.

Must-Have Skills & Experience

• Strong experience with TypeScript in production environments.
• Solid knowledge of Node.js (backend) and React (frontend).
• Experience with relational databases (SQL) and at least one NoSQL database.
• Comfortable working on both frontend and backend codebases.
• Willingness to touch and debug C++ code, even if you rely on LLMs and documentation to do so.
• Good understanding of software engineering practices: testing, code reviews, CI/CD, version control (Git).
• Fluency in English (spoken and written).

Nice to Have

• Experience with Apache Kafka or similar event streaming platforms.
• Understanding of event-driven design and message-based architectures.
• Experience with Docker, Kubernetes, or cloud platforms.
• Interest in blockchain, crypto assets, or fintech.
• Experience in high-availability, low-latency, or data-intensive systems.

What We Offer

• A chance to work on modern and innovative products in blockchain analytics and compliance.
• A modern tech stack where you can really influence technical decisions.
• An international and friendly team based in Belval, Luxembourg.
• Hybrid work is possible, following Luxembourg rules for remote work.
• Plenty of room to grow: training, conferences, and hands-on learning with LLMs and new technologies.

Our Hiring Process

We keep the process simple and transparent:

1. Interview with our CTO (60 min)

A technical discussion about your experience, how you solve problems, and the technologies you like to work with.

2. Interview with our Product Manager (30 min)

A conversation about how we work, our product culture, and how you collaborate with other teams.
