QA Engineer at Friendliai

ABOUT THE JOB Friendli Suite is our SaaS platform that includes microservices, a frontend, multi-cloud infrastructure, enterprise authentication, billing, and organization management. However, what makes this role unique is that our platform delivers AI inference. Validating whether inference works well is a problem that traditional QA methods do not fully solve. A deployment can succeed technically and still produce poor inference. We are looking for a dedicated QA engineer who can own the product's quality, ensuring our product works the way any well-run SaaS platform should, while also developing the approaches needed to validate AI inference quality, model deployments, and integrations that traditional testing alone cannot cover. KEY RESPONSIBILITIES - Own quality across FriendliAI's full platform stack: backend microservices, frontend, model deployments, and inference pipelines. - Build and maintain automated test suites using pytest, covering unit, integration, and regression testing across backend services. - Develop and run load and scalability tests using Locust to validate platform performance under real-world conditions. - Own frontend and end-to-end testing with Playwright across the full user-facing product. - Design and implement test strategies that account for LLM inference. - Work closely with infrastructure and backend engineers to validate model deployment workflows, multi-cloud orchestration, and service integrations. - Identify coverage gaps, prioritize test investment, and build tooling and pipelines. QUALIFICATIONS - 3+ years of experience in software quality engineering, with a track record of owning test strategy. - Bachelor's or Master's degree in Computer Science, Computer Engineering, or equivalent. - Proficiency in Python and hands-on experience with pytest for test automation. - Experience with load and performance testing tools such as Locust. - Experience with browser automation and end-to-end testing frameworks such as Playwright. - Working knowledge of LLM serving. - Strong experience testing distributed systems with multiple interconnected components. - Strong systems thinking. - Comfortable working in a fast-moving environment. PREFERRED EXPERIENCE - Familiarity with AI infrastructure or model serving systems - Experience building QA infrastructure from scratch in an early-stage or scaling environment. - Background in performance and scalability testing for cloud-native or multi-cloud systems. - Experience covering both backend and frontend testing in a single role. - Exposure to observability tooling and how it supports debugging and quality validation. BENEFITS - Flexible working hours - Daily lunch and dinner provided; unlimited snacks and beverages - Supportive and highly collaborative work environment - Health check-up support and top-tier equipment/hardware support - A front-row seat to the generative AI infrastructure revolution - Competitive compensation, startup equity, health insurance, and other benefits.
