The Position

We are looking for an intern in automation and project management to join our Client Delivery Management (CDM) team, as part of a 6-month internship, with a possible start between February and April 2027.

Our CDM team supports our clients in the deployment, customization, and evolution of our trading platform, from API connectivity to the configuration of trading workflows.

As part of a continuous improvement approach, we have recently deployed Rocketlane, a platform dedicated to project management and client onboarding.

Your mission will be to develop automation solutions, optimize existing processes, and integrate Rocketlane with our internal tools, in order to simplify the daily work of our project managers, ensure reliable activity tracking, and reduce repetitive tasks.

This internship will allow you to evolve at the intersection of technology, project management, and financial markets, by participating in concrete projects in an international environment.

Your Missions

• Process Analysis and Optimization: Study the current use of Rocketlane and identify manual tasks that can be automated: project creation from templates, follow-ups, status updates, and reporting.

• Development and Automation: Design and develop scripts and automations, particularly in Python, leveraging Rocketlane's APIs and webhooks.

• Tool Integration: Improve the interconnection between Rocketlane and our internal tools (ticketing, support, documentation, client directories) to limit duplicate data entry and streamline information sharing.

• Monitoring and Reporting: Contribute to the creation and improvement of dashboards, performance indicators, and project tracking tools.

• Client Project Participation: Take part in actual onboarding projects to understand operational needs, including connection testing, trading workflow configuration, and documentation.

• Cross-functional Collaboration: Work closely with the Client Delivery, Development, Support, and Product teams to understand their needs and propose suitable solutions.

Profile Sought

• You are pursuing a degree at the Bac+5 level (Master 2 or final year of engineering school) in computer science, engineering, finance, or an equivalent field.

• You have good programming foundations, ideally in Python, and you understand how APIs work. Knowledge of webhooks or automation tools is a plus.

• You are comfortable with both technical aspects (programming, integrations, automation) and functional aspects (project management, business processes, client needs).

• You are proficient in French and English, both written and spoken, and you are comfortable communicating in an international environment.

• You are curious, rigorous, autonomous, and possess good analytical skills. You enjoy understanding how tools work, identifying areas for improvement, and proposing concrete solutions.

• You appreciate teamwork and can collaborate with stakeholders from diverse backgrounds, both technical and functional.

• You are interested in new technologies and financial markets, and you want to discover the challenges of electronic trading in a FinTech environment.

What We Offer You

• A concrete and responsible project: Directly contribute to improving the processes and tools used daily by our Client Delivery team.

• Technical and functional experience: Develop your skills in programming, automation, API integration, and project management in a FinTech environment.

• An international environment: Interact with colleagues and teams located in Europe, North America, the Middle East, and Asia.

• Personalized support: Work alongside experienced professionals and develop your skills on real-world issues.

• A collaborative culture: Join a human-sized, innovative, and multicultural company where initiatives and ideas are encouraged.

• An internship allowance between €1,300 and €1,700 gross per month, depending on your profile and in accordance with company policy.
