The Senior CI / Build Systems Engineer will own and advance mobile CI, build, test, and developer-facing observability systems.

The position also helps establish App DevX as a trusted platform team within Oura.
What You Will Do
- Design, maintain, and optimize mobile CI systems at scale for iOS and Android, including pull request, merge, and release pipelines. Measure and improve CI runtime, queue time, and merge failure rates.
- Build and manage CI infrastructure, including runner fleets. Plan for capacity, ensure reliability, and implement caching, sharding, and parallelization strategies. Collaborate with infrastructure teams to meet performance goals.
- Act as the technical expert for mobile build systems, focusing on Gradle (Android) and Xcode/Tuist (iOS). Improve build performance and consistency, and align local and CI environments to reduce discrepancies.
- Oversee test architecture and stability. Define and refine approaches for unit, integration, and UI tests. Set standards for detecting, quarantining, and fixing flaky tests. Work with Testing and Release teams to surface useful signals earlier in CI.
- Manage developer-facing observability for pre-release workflows. Ensure robust logging, metrics, and tracing. Make sure CI environments provide clear, actionable insights about app behavior, performance, and regressions.
- Set technical direction and long-term strategy for mobile CI, build systems, and observability. Mentor other engineers on the team.
