We're looking for a Staff Software Engineer in Test to raise the quality bar across our mobile app and backend domain - not by owning a test suite, but by changing how the whole domain designs, ships, and trusts its software.

This is a hands-on technical leadership role. You'll shape architecture for testability and reliability, own the quality gates that let teams release with confidence, and build a culture where engineers own quality rather than hand it off. You'll operate as a true Staff Engineer: setting technical direction across several teams, going deep in the codebase when it matters, and framing quality as an engineering and business outcome - not a QA phase at the end.

If you've done this in a product with real mobile scale, even better.

Your scope of work will cover 3 areas.

I. Quality architecture & engineering

• Set and own the quality and reliability strategy across the domain - from the API/contract layer through to native iOS (Swift/SwiftUI) and Android (Kotlin) clients.
• Design for testability and release confidence: quality gates inside release and store-deployment pipelines, device and OS-version fragmentation coverage, and flakiness control at scale (BrowserStack + GitLab CI).
• Keep the backend/API/contract layer strong and connect it cleanly to the mobile client layer.
• Drive resolution of quality and reliability issues that cross team boundaries within the domain.
• Get hands-on in the codebase where your depth moves the needle - prototypes, tooling, reference implementations, thorny incidents.

II. Technical leadership, coaching & culture

• Shift quality ownership left into the engineering workflow - be the person teams pull in before implementation starts, not after.
• Mentor senior engineers across the domain and accelerate real, visible growth.
• Run knowledge-sharing across the org: tech talks, workshops, reusable documentation, pair sessions; co-lead the OneTech community.
• Co-shape the domain's technical direction with the SEM, with full autonomy within the domain, and analyse quality trends from metrics to identify where to improve.
• Define quality and reliability metrics and gates, and use them to frame risk in business terms for EMs, SEMs, and PMs.

III. AI governance in engineering

• Define how AI is adopted for quality and engineering productivity in the domain — which tools, which workflows.
• Design AI-assisted workflows and set governance and data-security standards across teams.
• Assess and manage the risk of AI usage (including production-facing work), not just the productivity upside.
• Mentor engineers on responsible, effective AI use and report on its ROI.

• 8+ years of software engineering experience, with a track record operating at Staff / Principal / Tech Lead / Architect level - proven impact beyond a single team (standards set for multiple teams, or a cross-team initiative led).
• Proven experience in testing in at least one mobile platform (iOS or Android) using market standard approaches as well as commercial, working-level experience with testing native mobile apps.
• Deep ownership of quality and reliability as an engineering discipline - you've set standards and designed testing/quality strategy (not just executed someone else's plan) and changed outcomes measurably.
• Proven shift-left experience - entering the process before code is written and measurably moving the result.
• A strong hands-on engineering foundation - you can read, review, and write production-quality code, and teams respect your technical depth.
• Experience leading technical and process change directly with development teams.
• A hands-on, critical relationship with AI - using it and assessing its risks, not just its benefits.
• Fluent English.

Strong plus - this is where you'll stand out

• Experience with BrowserStack and CI/CD (GitLab).
• Snapshot testing experience (e.g. swift-snapshot-testing, Paparazzi) and introducing mock-based testing standards.
• Experience in the logistics or e-commerce industry.
• Fluency in Polish.
• Familiarity with Appium (useful for understanding what we're migrating away from).
• Experience applying AI in engineering / testing workflows.
• ISTQB Advanced Level – Test Automation Engineer certification.

Additional Information

• An international, cross‑functional environment with experienced engineering leaders.
• The opportunity to work on products used by millions of users across Europe.
• Real ownership and influence over teams, technical direction, and long‑term solutions.
• Flexible working model with remote options in Poland.
• A strong engineering culture focused on quality, collaboration, and impact.
• We offer a B2B contract.
