Senior Android Engineer CICD (Freelancer)

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.

As a Freelance Senior Android Engineer youll 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 youve 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
  Youve 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 YOURE WALKING INTO
Were 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 1618% of the time and one test job once failed 600 runs in a row before anyone noticed. Theres a #ci-alerts channel that needs someone who wants to be in it. If that reads as a mess this isnt your role. If it reads as an unusually clear mandate with visible impact on every engineer in the company we should talk.

We look forward to your application and cant wait to meet you no matter who you are or what background you have!
