About RentsyncRentsync is an award-winning, high-growth organization that provides high quality websites, marketing services, and software solutions to the rental and property management industry throughout Canada and the United States.About The RoleWe're building the products that will define the next decade of rental housing technology, and we need a senior QA Engineer embedded in the team building them. You will define what quality means for products that are genuinely new, build the systems to measure it, and own the testing approach end to end. You will work across two very different surfaces: established web platforms with the functional and regression rigor you'd expect, and newer AI‑infused products whose behavior isn't fully predictable, where "correct" isn't a single expected output.What You'll TestConversational and interactive products where the same input can produce different outputs from one run to the next, testing for quality, consistency, and secure failure rather than one "right" answerCore web platforms across the rental housing / proptech landscape: functional, regression, cross-browser, and performance testingThe integrations and data flows that connect themTools You May Work WithPlaywrightTypeScript / JavaScriptREST API testingCI/CD pipelinesand the freedom to bring in whatever modern tooling scales your coverageDuties & ResponsibilitiesOwn the testing strategy and approach for the team's products, end to endDesign, build, and maintain automated test suites in Playwright and TypeScriptDefine what "good" looks like for open-ended outputs, where there's no single expected result, and build the evaluation frameworks, scorecards, and regression harnesses that measure it objectively over timeEstablish quality standards, test practices, and review habits the wider team adoptsLean on a modern,



fast-moving toolchain to multiply your coverage; you reach for automation and assistive tooling rather than testing everything by handRun exploratory and manual testing where human judgment matters mostPartner with engineers and product from design through release; shift quality upstream rather than catching problems at the endTriage, reproduce, and clearly document defects, and track quality signals through to productionIntegrate testing into CI/CD to give the team confidence to ship quicklyRequired Knowledge, Skills & AbilitiesStrong hands‑on test automation with Playwright (or a comparable modern framework) in TypeScript / JavaScriptComfort testing systems with variable or non‑deterministic behavior; you're energized, not frustrated, by problems that don't have one correct answerExperience defining quality for subjective or open‑ended outputs: what makes a result complete, accurate, on‑tone, and safeFluency with a modern testing toolchain, and a habit of adopting new tools quickly to scale what one person can coverSenior‑level communication: you can set a quality bar with engineers and explain a risk trade‑off to a stakeholder in the same conversationStrong analytical, debugging, and problem‑solving skillsEssential Qualifications5+ years in QA or quality engineering, including building and maintaining automated test suitesA track record of owning quality for a product or product area end to end, not just executing test plansAdditional Preferred QualificationsAutomated API testing experienceExperience integrating test suites into CI/CD pipelinesExperience testing conversational, chat, or natural‑language interfacesExposure to building evaluation datasets, scorecards, or quality benchmarks for product outputsBackground in PropTech, marketplaces, or high‑volume consumer platformsThe Pay Range For This Role Is70,000 - 90,000 CAD per year (Canada)#J-18808-Ljbffr
