DevOps / Infrastructure Engineer - Internship

It all started with an idea in 2021. Initially built to democratize Bitcoin in France, Bitstack has gone from a simple product that invests spare change in bitcoin, to a crypto-native bank bringing a better way to save, spend, and grow money to our 300K+ users. We want to rebuild finance from the ground up to empower people to achieve financial freedom by participating in a more open and inclusive financial system. We’re a small, ambitious team of operators. We believe in moving fast, sweating the details, and creating products people truly love.

At Bitstack, you’ll have the opportunity to shape not just our products, but the culture and practices of our entire organization. Bitstack is backed by YC, leading VCs like 13books Capital, Stillmark, Serena, and many more. We are building a product our users love and we are just getting started! The Role Bitstack runs dozens of interconnected backend services on Google Cloud. As the engineering team grows, we want every engineer to be able to test their changes end to end, quickly and independently, before they reach our shared environments.

As part of the Infrastructure team, you will build a local test environment for our backend engineers and QA. The goal is simple: anyone can start our backend services and their dependencies on their own machine with a single command, reproduce real business scenarios and test asynchronous flows end to end. You will own the project from the initial assessment through to company-wide adoption.

• Assessment & Recommendation - Learn our stack (Go and Python services, Bazel, Docker, Kubernetes, GCP) and map how our services depend on each other. - Evaluate the test tooling and emulators already in our codebase, as well as the tools available on the market. - Recommend an approach, and record your tooling choices and trade-offs in a decision log.
• Building the Local Environment - Start with a pilot cluster of interconnected services and get it running locally with a single command. - Solve the real problems as they come up: configuration and secrets, service-to-service authentication, cloud dependencies (Pub/Sub, Cloud Tasks, databases, caches) and async workers. - Extend coverage cluster by cluster until every backend service is included.
• Scenarios, Data & Adoption - Build seed data and scripts so that any user state, limit or time-based event can be reproduced and reset on demand. - Work with backend engineers and QA as your first users, gather their feedback and fix what breaks. - Write documentation clear enough for a new engineer to get set up on their own, and support the team through the switchover. By the end of the internship, you will turn your decision log into a recommendation report and hand over a tool the team will keep maintaining. You will gain hands-on experience with a production-grade microservices architecture on Google Cloud, and see how a platform tool is designed, built and adopted by an engineering team. You will learn how infrastructure decisions are made and documented, and work closely with backend, QA and infrastructure engineers, with mentoring from a DevOps engineer throughout.

Currently in the final year of an engineering school or Master’s degree (Bac+5) in Computer Science or a related field, and looking for a 6-month end-of-studies internship starting in early 2027.

• Hands-on experience with Docker and a working knowledge of Kubernetes.
• Comfortable with Linux and scripting (shell, Python or similar).
• Previous experience with a cloud provider, through an internship, a project or coursework. GCP is a plus.
• Experience with Go, Bazel or Docker Compose is a plus, but not required.
• Curious and autonomous: you like to understand how a system fits together before changing it.
• Able to explain technical trade-offs clearly, in writing and to the engineers who will use what you build.
• Fluent in English. French is a plus.
• Based in Paris or happy to relocate for the internship. Exceptional candidates elsewhere in France who’d prefer to work remotely are welcome to apply too. Perks &
