Backend Engineer Intern (6 months starting February 2027)

Team: Engineering

Location: Paris

Commitment: Internship

Workplace Type: onsite

👫 About the team

At Equativ, we’re on a mission to develop advertising technologies that empower our customers to reach their digital business goals. This means that we rely on massively scalable, widely distributed, highly available, and efficient software systems; the platform deals with over 6 million requests per second (+500 billion/day) handled by 3,500+ instances with less than 250ms response time.

Our innovation team based in Paris, Nantes, Limoges, Montreal, Krakow and Berlin is composed of 190+ straightforward and energetic engineers working in an agile environment and ready to tackle the most complex technical challenges.

👇 Your mission

    You will join our fast-growing R&D within the exchange backend development teams. Your specific team’s mission is to improve our ad exchange platform seeking better performance, higher maintainability and faster scalability. As a member of the team, you’ll get to work on production challenges, whether they are short-term focused (e.g. improving an algo to save CPU) or shaping the future of our platform (e.g. scaling it for the cloud). As an intern, you’ll get to learn and grow within an international team composed of several areas of expertise. You will join the Auctioning feature team, made up of 5 developers, a Product Owner and a QA engineer, working at the heart of our real-time auction engine. You’ll report directly to a Senior Engineer in this team.

What you'll do ✏️

    • Work in an agile, international and multi-expertise team composed of software engineers, QA and DevOps.

    • Ship your applications with GitLab and ArgoCD/Kubernetes.

    • Improve our end-to-end test reliability and tooling.

    • Participate in maintaining our stack to the newest .NET release.

    • Participate in our daily features development.

    • Monitor your features in production with Grafana and Datadog.

    • Work on data flows with Kafka, Aerospike, SQL Server and BigQuery.

    • Develop with Claude Code and help improve our AI efficiency.

    • Learn a lot by working on one of the biggest productions of French tech!

About you 💪

    Must have:

    • Master’s or engineering-school student looking for an internship.

    • Professional efficiency in verbal and written English.

    • Serious doubts about the saying “Testing is Doubting”.

    • Passion for writing, reviewing and judging high-quality and maintainable code following agile principles.

    • Appetite for learning and technical challenge.

    • Coding skills with object-oriented programming (C#, Java, C++…).

    • SQL basics. 

      • Nice to have:

      • Experience with modern .NET (C#, ASP.NET Core).

      • Curiosity about performance and low-level .NET (memory, GC).

      • Interest in distributed systems and cloud development.

      • Personal projects with code sharing, we’re curious about your art!
