Senior QA Engineer

In this role, you'll ensure the reliability and performance of Apiphani's multi-platform ecosystem spanning web, desktop, and AI services. You’ll work across a diverse tech stack — from TypeScript and Go to Python-based AI systems — establishing quality standards, driving automation, and ensuring smooth, production-ready releases. This role sits at the intersection of traditional QA and AI observability. You will design, implement, and maintain comprehensive test strategies across multiple repositories and tech stacks. You will develop and execute end-to-end tests for our React/Express TypeScript applications using Cypress. You will monitor and optimize AI service performance, observability, and prompt versioning using tools like LangSmith. You will collaborate closely with developers, DevOps, and product teams to resolve bugs before production.
