🏢 Summary: Lead the QA strategy as a Confidence (QA) Manager, driving automation and quality culture across Web and Android POS products used in high-pressure restaurant environments. Own automation frameworks, CI/CD testing pipelines, and device labs while mentoring a QA team and embedding shift-left testing practices. Ensure resilient, high-performance, zero-downtime user experiences across critical ordering and payment flows. 🗂️ Requirements: 3+ years leading QA or software testing teams, Hands-on experience in automated testing for Web or Android, Experience designing and maintaining automation frameworks, Experience managing device testing labs, emulators, or cloud device farms, Experience implementing CI/CD testing pipelines, Ability to define and track quality KPIs, Fluent English (written and spoken) 📃 Skills: Playwright, Cypress, Espresso, Appium, Kotlin, React, TypeScript, Python, Django, Go, PostgreSQL, Docker, GitHub, CI/CD, Android, AI, LLM 🏢 Description: We’re not just building restaurant tech, we’re giving independent restaurants the tools to compete and win.

If you’re looking to make an impact with heart and hustle, SpotOn is the place for you. At SpotOn, we don’t believe in "QA" as a safety net that catches bugs at the very end of a sprint. We believe in Confidence —the absolute certainty that the code we ship today empowers our merchants to run their businesses flawlessly tomorrow. As a Confidence (Quality Assurance) Manager , you will lead the strategic vision and the team responsible for manual and automation testing across our products. You will guide our Automation Testing (AT) strategy, build robust tools, and—most importantly— foster a culture where the mindset of writing automated tests is shared by every single software engineer on the team. You will be a technical leader, a experience advocate, and a coach, ensuring our testing velocity matches our ambitious product roadmap. Why This Role Matters (Core Business Impact) Our software does not run in sterile, quiet offices. It runs in chaotic, high-heat, high-noise environments. Picture a Saturday night dinner rush: kitchen staff are rushing, servers are tapping screens with greasy or wet fingers, the Wi-Fi network is fluctuating, credit card readers are dropping connections, and the printer just ran out of paper mid-receipt. In this environment, staff have zero patience for sluggish UI transitions, and there is no room for error. High staff turnover in the US hospitality industry also means our systems must be incredibly intuitive—any UX friction leads to order mistakes and lost revenue. A system crash, a broken payment flow, or even a 3-second lag during peak hours doesn’t just mean a minor glitch; it means cold food, lost tips for hard-working servers, angry diners, and thousands of dollars in lost revenue for the restaurant owner. Your mission as a Confidence Manager is to address these harsh, real-world conditions: Where Code Meets Physical Chaos: Ensure our software is resilient to the unexpected—such as unexpected network dropouts (offline-mode reliability), hardware peripheral disconnects (printers, cash drawers, terminals), and rapid, muscle memory UI tapping. UX and Real-User Experience Focus: Champion tests that measure actual user perceived latency, UI transitions, and end-to-end user journeys rather than just validating API endpoints. Zero Downtime during Peak Hours: Guarantee that critical login, getting menu updates, checkout, ordering, payment flows, and end-of-day reports are bulletproof across Web and Mobile platforms through regression coverage. Rapid Time-to-Market: Accelerate feature shipping by building automated, self-healing, and highly reliable CI/CD test feedback loops, removing human-bottleneck manual validation. On a daily basis you will: Drive the "Shift-Left" Quality Culture: Work closely with Engineering Managers to embed quality early in the development lifecycle. Foster a shared-ownership model in which writing automated tests is a standard practice for all software engineers. Lead and Coach: Manage, mentor, and grow a team of Confidence (QA) Engineers. Conduct 1:1s, support career progression, and foster a healthy, continuous-learning team dynamic. Own the Automation Strategy: Design and continuously refine our Automation Testing (AT) platforms and frameworks for Web and Android environments. Manage the Device Testing Lab: Oversee the infrastructure for automated testing on physical Android stations, handhelds, and peripherals, combining emulator tests. Leverage Modern AI Tools: Champion the integration of generative AI and LLM-assisted tools (e.g., Claude, automated test generation, visual regression analysis, AI-driven self-healing test scripts) to dramatically speed up the creation and maintenance of automated tests. Maintain the Testing Platform: Work closely with DevOps and Platform teams to build and maintain ultra-fast, reliable CI/CD pipelines (e.g., via GitHub Actions) that the engineering organization fully trusts. Define Quality Metrics: Track and expose actionable quality KPIs (such as user-perceived performance, test coverage, execution speed, flaky test rates, and defect leakage) to drive data-informed improvements. What skill are we looking for? Management Experience: 3+ years of experience leading, mentoring, and scaling high-performing QA or software testing teams. Strong Automation Background: A proven hands-on technical background in automated testing for Web (e.g., Playwright, Cypress) or Android (e.g., Espresso, Appium, Kotlin automation). Having experience in both is a massive plus. UX and Experience Advocate: You don't just test functionality; you test usability. You have empathy for the end-user (the server, the chef, the diner) and have experience setting up visual regression, performance budget testing, and perceived latency benchmarks. Lab & Device Infrastructure Knowledge: Experience managing device testing matrices, cloud device farms or emulators, and physical test environments containing connected POS hardware. The "Shared-Quality" Mindset: A strong track record of teaching, influencing, and persuading developers to take ownership of test automation. You know how to make automated testing a low-friction process for all engineers. AI & Velocity Booster: Experience or clear, practical strategies for utilizing AI tools to accelerate automated test authoring, visual UI validation, or test maintenance. Pragmatic Problem Solver: You have the "Figure it Out" gene. You prefer end-user outcomes and business impact over technical purity. Excellent Communicator: Fluent in English (written and verbal), with the ability to articulate quality-related challenges, environmental edge cases, and trade-offs to both technical and non-technical stakeholders. Perfect candidate also has: Familiarity with our current stack: React (TypeScript), Python (Django), Go, Kotlin, PostgreSQL, Docker, GitHub Actions . Domain experience in Fintech, Merchant Services, Point of Sale, or SaaS hospitality platforms. Here’s a bit about what we have to offer: Competitive salary Training budget 3500 PLN gross per year.
