About Bitstack
Bitstack is a mobile application designed for effortless saving and investment in Bitcoin. The app allows users to buy and sell Bitcoin starting from €1, invest spare change through round-ups on purchases, or set up recurring buys (hourly, daily, weekly, monthly). It also facilitates sending and receiving Bitcoin to other Bitstack users or external Bitcoin addresses. Bitstack is licensed as a Crypto-Assets Service Provider (CASP) with the French Financial Markets Authority (AMF) and operates as an agent of Xpollens, an electronic money institution. The service is available in several European countries, including France, Germany, Spain, and Italy. Bitstack was created to offer an alternative to traditional savings, which lose value over time due to inflation. The company aims to make it easy for people to build solid, healthy capital through Bitcoin to fund their life goals. The founders state their mission is to democratize access to Bitcoin, which they see as key to wealth creation and economic freedom, allowing everyone to take control of their money and protect their future. Their guiding values are customer focus, inclusivity, staying focused on their mission, and transparency.

About the Role
You will join the Infrastructure team to build a local test environment so any engineer can start backend services and dependencies on their own machine with a single command. You will assess the stack and available tooling, recommend an approach and record decisions in a decision log. You will then build a pilot cluster locally, solve configuration, secrets, authentication, cloud dependency and async worker challenges, and extend coverage to all backend services. You will also build seed data and scripts to reproduce and reset scenarios, gather feedback from backend engineers and QA, write documentation and support the switchover. By the end you will deliver a recommendation report and hand over a tool the team will maintain.
