Company Description

Natixis Corporate & Investment Banking is a leading global financial institution that provides advisory, investment banking, financing, corporate banking and capital markets services to corporations, financial institutions, financial sponsors and sovereign and supranational organizations worldwide.

Our teams of experts in close to 30 countries advise clients on their strategic development, helping them to grow and transform their businesses, and maximize their positive impact. Natixis CIB is committed to aligning its financing portfolio with a carbon neutrality path by 2050 while helping its clients reduce the environmental impact of their business.

As part of Groupe BPCE, the second largest banking group in France through the Banque Populaire and Caisse d’Epargne retail networks, Natixis CIB benefits from the Group’s financial strength and solid financial ratings (Standard & Poor's: A+, Moody's: A2, Fitch Ratings: A+,R&I: A+).

Job Description

You are joining our production and IT support teams for the Fixed Income, FX, and Credit activities, who are looking for a developer, for an internship of 6 months from January 2027.

The teams support users in the trading rooms and ensure the smooth running of the applications necessary for their activities. Support requests are now mainly made in several Microsoft Teams channels. The multiplication and fragmentation of exchanges make it difficult to identify new requests, monitor their processing and ensure that no request remains unanswered.

A POC was developed to extract and structure Teams conversations, then analyze them using artificial intelligence to identify support requests. The objective of the internship is to industrialize this POC in order to make it robust, maintainable, and integrated into the information system.

In collaboration with your tutor, your main tasks will be:

• Understand the activities of the production and support teams as well as the functioning of the existing POC;
• Define and implement an architecture to industrialize the collection and analysis of Teams conversations;
• Make the detection, grouping, and qualification of support requests more reliable using artificial intelligence;
• Develop the APIs and integration mechanisms needed to create and synchronize tickets in ServiceNoW;
• Design a web console to view, filter, assign and track requests in real time;
• Set up testing, logging, supervision, error management, and continuous integration;
• Document the solution and prepare it for support by production and support teams.

You will also have access to the works council.
