QA/AQA Engineer (Middle+)
First seen by Alion on Oct 12, 2026.
We are looking for a QA Engineer to join our team working on an AI-powered drug discovery SaaS platform. The platform combines molecular screening, ADMET analysis, peptide optimization, and Datagrok integration. You will work closely with developers, product owner, and biologists to ensure quality across all platform features.
This is not an execution role — it is a leadership role. You will be the first dedicated QA Lead at Receptor.AI, responsible for building QA processes from the ground up, defining testing strategy, and setting quality standards across the platform. We expect you to take full ownership of quality and drive it forward independently.
