About the role

  • Develop and optimize new features on our internal web application built with React.
  • Design and maintain back-end services and APIs using Node.js.
  • Integrate data extraction tools, evaluation models, and M&A-oriented utilities into a knowledge graph-centered architecture.
  • Contribute to the platform's architecture, performance, and scalability, leveraging Graphiti and knowledge graph technologies to structure and query complex datasets.
  • Improve the overall UX/UI in close collaboration with business teams.
  • Participate in technical discussions on architecture, best practices, and the platform roadmap.

Requirements

  • You have experience with Node.js for building APIs or back-end services.
  • You are familiar with or eager to learn knowledge graph technologies and graph-oriented data modeling (e.g., Graphiti, RDF, SPARQL, etc.).
  • You enjoy solving problems, designing internal tools from scratch, and thinking from the user's perspective.
  • You are autonomous, curious, detail-oriented, and able to collaborate in a professional environment.
  • Additional plus (not mandatory): an interest in finance, M&A, or building internal tools for consulting workflows.
Benefits
  • High-impact experience: active participation in developing a strategic internal platform for a leading investment bank.
  • Modern technologies: daily work with React (TypeScript), Node.js, Python, Graphiti and knowledge graph technologies.
  • Real responsibilities from day one, with a high degree of autonomy and the ability to see your contributions quickly in production.
  • International and stimulating environment, interacting with business (finance/M&A) and technical multicultural teams.
  • Accelerated learning opportunities, with support and mentorship on software architecture, best practices, and data engineering.
  • Exposure to varied challenges: data engineering, performance, scalability, UX/UI, and consulting-oriented internal tools.
  • Entrepreneurial, results-oriented culture where personal initiative is valued and encouraged.
