INTERNSHIP 2027 – Software Engineer C++

Team & Context:

At Murex, Software Engineers design, develop and maintain the technologies that power the MX.3 platform, used by financial institutions worldwide.

Our C++ engineers work on technical components at the core of the platform. Their projects cover areas such as low-level development, programming languages, distributed systems, performance, observability, software reliability and developer tooling.

Joining this internship means becoming part of a community of experienced engineers working on challenging software development topics. You will contribute to a concrete technical project while gaining hands-on experience with the architecture and development of a large-scale financial software platform.

Your missions / What you’ll do?

Following an onboarding program covering software engineering practices and the MX.3 platform, you will contribute to a project with direct technical impact. Depending on your assignment, you may:

• Design, develop and test software components in C++;

• Analyze existing code, execution flows and technical architectures;

• Improve the robustness, readability, performance and maintainability of existing solutions;

• Contribute to low-level development and algorithmic topics;

• Enhance monitoring, diagnostics and troubleshooting capabilities;

• Work on programming language features, compilers or static analysis mechanisms;

• Collaborate closely with software engineers, architects and product experts;

• Document your approach and present your findings and solutions to technical stakeholders.

A glimpse of the topics you could work on:

Our interns contribute to a variety of technical initiatives across the Software Engineering perimeter.

The topics you could work on include:

• The evolution of observability capabilities within the MX.3 platform, including the implementation of consistent metrics, logs and traces;

• The adoption of modern instrumentation standards such as OpenTelemetry;

• The propagation of contextual information across execution flows;

• The development and evolution of proprietary programming languages used within MX.3;

• The implementation of new language features, including stronger static typing mechanisms;

• Semantic analysis and compiler improvements designed to detect inconsistencies before execution;

• Monitoring, troubleshooting and diagnostic tools supporting platform reliability;

• Improvements to software quality, maintainability and developer experience.

Each internship assignment is built around a real technical challenge and provides hands-on exposure to software engineering within the capital markets technology industry.
