By transforming data into actionable insights, we enable financial professionals to deliver exceptional client experiences, make better decisions and grow their businesses sustainably.
As our platform continues to evolve, data is at the heart of everything we build. That's why we're looking for a Senior Data Engineer who wants to shape the next generation of data-driven products, AI-powered applications and scalable platform services. You'll work with modern technologies, take ownership from idea to production and have a direct impact on the products used by thousands of financial professionals across Europe.

Your role and responsibility

• Maintain and optimise data pipelines. You work with our Airflow pipelines to ensure reliable data processing, high data quality and strong performance. You continuously improve existing pipelines and integrate new data sources where needed.
• Apply AI where it adds value. You contribute to Machine Learning models and LLM-powered applications, helping bring technologies such as RAG, vector search and Agentic AI into practical, production-ready use cases.
• Support analytics and BI. You collaborate closely with our BI team, optimise SQL queries, improve data models and troubleshoot performance issues to ensure reliable analytical solutions.
• Write production-ready software. You turn ideas and prototypes into robust, tested and maintainable applications using modern software engineering practices.
• Stay curious. Technology evolves quickly—and so do you. You enjoy learning, exploring new tools and experimenting with emerging AI and data technologies to continuously improve your work.
• Collaborate and share knowledge. You work closely with Product, BI, Software Engineering and business stakeholders. Through code reviews, technical discussions and knowledge sharing, you actively contribute to the success of the team.
