We’re hiring a Principal Quality Engineer who designs quality into the system, not after it. You’ll shape the testing strategy across a platform of 80+ production services, build the automation that makes it real, and write the code that ships alongside the engineers you partner with. This is a hands-on technical role: you’ll work with senior and principal Quality Engineers and software engineers as peers, everyone pulling their own weight and expecting the same from others. You design the test architecture, you build it, you own it in production, partnering with our other principal Quality Engineers to shape it across the platform. Three days a week you’ll be on-site at our North York office, working directly with Quality Engineers, software engineers, and product leads across teams. Our team uses AI tools like Cursor, Claude, and Gemini as a core part of how we work, not as optional extras. You’re expected to use them daily to generate test suites, analyze failures, mine logs, and move faster than a traditional QA function ever could. You’ll be the quality champion across the delivery track: an analytical view of every initiative in flight, the judgment to decide where quality investment matters most, and the willingness to adapt as priorities shift. Not every feature gets the same coverage, and you’ll be the person engineers and product leads come to when they need to know where to invest and where to accept risk. We’re not hiring you to operate a finished quality function. The team still does manual testing where it makes sense, automation coverage is uneven across domains, and there’s real work to do on tooling and patterns. We’re looking for the best long-term hire we can make: someone who sees the gaps as the job and doesn’t wait to be asked to fix them. We’re looking for our next Principal Quality Assurance Engineer Could It Be You? Use Cursor, Claude, and Gemini as a core part of your daily workflow, not just for boilerplate generation, but for test strategy drafting, failure pattern analysis, log mining, and coverage gap identification. You know how to prompt for useful output, critically evaluate what comes back, and ship AI-assisted test code that meets the same bar as anything hand-written. Own the end-to-end quality strategy across our event-driven, domain-driven platform: contract testing between services, integration coverage across domains, end-to-end flows, performance baselines, synthetic monitoring, and production observability for quality signals. Partner with our other principal Quality Engineers to shape test architecture across domains, share ownership of platform-wide quality patterns, and hold each other to a high bar. Senior Quality Engineers and software engineers are part of the same collaboration loop. Build and maintain the test automation frameworks, harnesses, and shared libraries the rest of the platform depends on. Write the code yourself in C# / .NET and TypeScript. Our primary UI and integration automation today is built on Cypress and Playwright. You’ll work across both, improve what’s there, and make opinionated calls about where each belongs as the platform evolves. Design and run performance tests that produce signal, not noise. Establish baselines, surface regressions early, and partner with engineers to fix root causes, not symptoms. Lead investigation when things break. Instrument what’s missing, find the actual cause, write the test that would have caught it, and make sure it never escapes again. So are YOU our next Principal Quality Assurance Engineer ? You are if you… Demonstrated, hands-on fluency with AI development tools: Cursor, Claude, Gemini, or equivalents. We want to see evidence of this: AI-assisted test suites you’ve reviewed and shipped, prompting strategies that produced real signal, or workflow integrations that measurably changed how you work. Claiming daily use isn’t enough; we’ll go deep on this in the interview. 8+ years in software quality with a track record of owning quality at the platform or system level, not just on a single product. Track record of making quality investment decisions across multiple concurrent initiatives. You know when to invest in contract tests vs end-to-end vs chaos vs synthetic monitoring based on what’s actually shipping and what the risk profile looks like. Strong hands-on coding ability. You write production-grade automation, not glue scripts. Comfortable in C# / .NET and TypeScript. Hands-on experience with Cypress and Playwright is expected; deep expertise in one with proven ability to ramp on the other works too. Familiarity with k6 for performance and Pact for contract testing is a plus. Deep practical knowledge of testing distributed, event-driven systems: contract testing, integration patterns, async flows, idempotency edge cases, and the failure modes that only show up at scale. Experience designing performance test strategies for real production workloads, with the data analysis chops to interpret the results. Ability to communicate quality trade-offs clearly to both engineers and product leads. You can go deep on a flaky test with a developer and talk risk profile with a PM without losing either audience. Comfortable with in-person collaboration in North York three days per week. This role requires presence, not just availability. Additional kudos if you… Hands-on with Google Cloud Platform (GCP), our cloud environment, including Pub/Sub, Cloud Run, and observability tooling. Experience with chaos engineering or fault injection in production-like environments. Background in compliance-driven QA in regulated domains (financial services, fintech, healthcare). Open-source contributions, blog posts, or a portfolio that demonstrates quality thinking, not just bug counts. Need more details? Keep reading… You’ll have real authority over how quality is defined and measured, not an advisory seat. You’ll work with a team that ships frequently, takes AI tooling seriously, and treats quality engineering as a first-class input into how systems are designed, not a gate at the end. If you want to work at a level where the test architecture you design is the test architecture that gets built, we want to talk. Additional Information… This role requires three days of in-office presence per week for Greater Toronto Area (GTA) residents. For candidates residing outside the GTA, a remote workplace arrangement is available. Compensation Information: Base salary range: $140,000 - $160,000. The final package will be commensurate with experience, skills, and geographic location (Canada). Includes a comprehensive benefits plan and a competitive incentive (bonus) program. Sounds like you?
