Description

Own and improve iOS build system performance, reliability, and debuggability across local and CI environments.
Diagnose and resolve build bottlenecks, non-determinism, and performance regressions.
Define and evolve iOS test architecture for unit, integration, and UI tests with a focus on determinism and signal quality.
Lead adoption of integration testing frameworks and patterns for iOS at scale.
Set standards and policies for flaky tests, including detection, quarantine, remediation, and enforcement.
Design and maintain iOS CI execution models, including simulator usage, sharding, and test parallelization.
Improve CI runtime, queue time, and failure rates through measurement and iteration.
Own and evolve Tuist-based project generation, structure, caching, and related tooling.
Improve developer workflows and local–CI parity to reduce “works on my machine” issues.
Use metrics, logs, and failure patterns to prioritize work and prevent regressions.

Requirements

Strong experience as an iOS engineer with a focus on build systems, test infrastructure, or developer tooling.
Deep understanding of Xcode builds, dependency graphs, and build performance optimization.
Experience designing or evolving iOS test architectures, including integration or UI testing at scale.
Experience operating and improving iOS build and test systems in CI environments.
Proven ability to improve local developer build and test loops for iOS engineers.
Comfort using CI metrics, logs, and failure patterns to guide debugging and prioritization.
Strong root-cause analysis skills and the ability to debug complex, non-deterministic failures.
Clear communication skills and the ability to work effectively with iOS engineers, platform teams, and partners.
Technical expertise in Xcode build internals, build settings, performance optimization, iOS test frameworks, CI execution models, Tuist, macOS environments, iOS toolchains, scripting and automation (Bash, Swift, Python), and Git workflows.
Nice to have: familiarity with developer-facing observability or instrumentation in pre-release environments, experience shaping CI standards beyond a single platform, mentoring experience, or exposure to cross-platform mobile build or test systems.

Benefits

Competitive salary.
Lunch benefit.
Wellness benefit.
Flexible working hours and work-life balance.
An Oura ring of your own.
Easy-to-reach offices in Oulu Teknologiakylä and Helsinki city center.
