Staff Software Engineer (iOS)

InPost is one of Europes largest out-of-home delivery networks with a consumer app used by over 10 million people. We are consolidating our separate market applications into OneApp: one application on one codebase for the whole InPost group across Europe and beyond with Italy live and Iberia in flight. This Staff role exists to make that happen. It sits above and between teams rather than inside one setting iOS technical direction across several mobile teams and working across domain boundaries with product backend platform QA and the other mobile disciplines. It does not own a feature backlog. It owns the decisions every teams code has to live with.

Must have

• Multi-market or white-label apps. Proven record of shipping a single codebase across several markets or brands with the variant configuration and release complexity that brings.
• Mobile architecture. MVVM Clean Architecture SOLID. Unidirectional and composable architectures Apples own or TCA. Deliberate justified choice per problem. Tuist is a plus.
• Modularisation and contribution model. Feature extraction from a monolith into meaningful modules. Publishing the architecture onboarding other domains ownership and review rules for shared code.
• Deep Swift and modern concurrency. async/await structured concurrency actors Sendable cancellation. Experience introducing Swift 6 strict concurrency into a large mixed codebase and a credible phasing plan.

• Business judgement. Separates what must happen now from what can wait. Quantifies technical debt and argues remediation in business terms. Turns Apple platform deadlines into a costed plan. Proven record of roadmaps delivered and debt resolved.
• Whole-problem thinking. Looks beyond the technical problem to product intent process and delivery. Works across the whole SDLC not only inside the code.
• Advanced AI-assisted engineering. Claude Copilot or Grok hands-on a strong plus. Harness agentic loop and graph engineering. Sets verification rules for AI-generated code and measures the return.

• macOS CI infrastructure. Runner provisioning Xcode versions simulator runtimes signing and certificates fleet reproducibility. On-premise cloud or hybrid.
