Job description
🎤 Why voize? Because we’re more than just a job!
At voize, we believe the greatest gift to frontline workers is time - time to care, connect, and be present. Today, that time is lost to admin work that pulls nurses away from what matters most: people .
💡 Your Mission
As a Freelance Senior Android Engineer , you'll take ownership of building and evolving our Android application, creating features that have a real impact on the daily lives of healthcare professionals. We are open to candidates based in France, Germany, or England , with a willingness to travel to our Berlin office from time to time (travel expenses covered). The initial contract is for a minimum of three month
Own the health of our mobile CI/CD pipeline end to end: ~70 Kotlin Multiplatform jobs, from lint to end-to-end tests to store release
Be the person who unblocks a broken master: triage the failure, debug the app itself (not just the pipeline), get 40+ engineers moving again

Attack the structure, not the symptoms: define what healthy CI means for us as actual SLOs, decide which jobs to keep, combine or gate the rest, and take our P95 pipeline from ~90 minutes to something nobody complains about
Make test flakiness visible and owned — dashboards, quarantining, a clear owner per failing test
Leave a trail: what you tried, what worked, and what already exists, so we build the muscle into our dev culture
YOUR SKILLSET – WHAT YOU BRING TO THE TABLE
Several years building Android apps with Kotlin and Compose — you've shipped to real users, not just to CI
Deep Gradle knowledge: multi-module builds, build caching, task/configuration avoidance, and a real answer to "why does this build take 20 minutes?" You've owned a CI/CD setup before (GitLab CI ideally): runners, caches, artifacts, change-based job gating
Comfortable in the unglamorous layers: emulators, macOS/iOS build agents, Appium/E2E flakiness, memory-hungry Kotlin compile jobs
Kotlin Multiplatform and/or iOS exposure is a plus, but most of the work feels like Android
You speak English fluently (C1) — German is a plus but not required
WHAT YOU'RE WALKING INTO ▎ We're not going to pretend this is greenfield. Our pipeline is ~70 jobs deep, P95 sits around 90 minutes, our two end-to-end suites fail ~16–18% of the time, and one test job once failed 600 runs in a row before anyone noticed. There's a #ci-alerts channel that needs someone who wants to be in it. If that reads as a mess, this isn't your role. If it reads as an unusually clear mandate with visible impact on every engineer in the company, we should talk.
