Full Job Posting
Role Summary
We are looking for a hands-on Software Development Engineer in Test (SDET) to join our AI-native product development team at onsemi and own end-to-end quality and release certification for a full-stack platform built on Next.js, React, TypeScript, Django, PostgreSQL, Redis, GraphQL, Airflow, MCP-based AI agents, Kubernetes, Helm, and Docker. This is a full-stack testing role covering UI, API, data, async job, and AI-agent layers, with accountability for certifying that each release meets functional, non-functional, and reliability bars before reaching production. The candidate should build durable automation frameworks and make heavy, responsible use of AI coding agents to design test strategy, generate and maintain suites, and triage failures faster.
Success Expectations
You should independently own end-to-end quality for the platform: building and maintaining a full-stack automated test pyramid (unit, API, integration, E2E, non-functional, and AI-agent evaluation), certifying releases against clear, evidence-based exit criteria, using AI coding agents responsibly to accelerate test authoring and triage, and partnering with engineering to continuously reduce defect escape rate without slowing delivery.
