The Role
As a Quality Assurance Engineer at Hadean, you will play a pivotal role in ensuring the quality and reliability of our cutting‑edge dominAI platform. You will be the primary QA resource for the dominAI product team, responsible for embedding quality practices throughout the development lifecycle, from initial story refinement to final deployment. This role is perfect for a QA generalist who excels in the early stages of development, helping to define and clarify acceptance criteria and crafting comprehensive test plans.
You will work in close collaboration with the QA engineer in our other product team. While you will each be responsible for the end‑to‑end quality for your respective teams, you will collaborate on cross‑team initiatives, review each other's work and provide mutual advice. While you will bring a strong focus on test planning and analysis, you will also need a solid foundation in test automation and infrastructure to contribute to our fast‑paced, automation‑first environment. Looking ahead, as our engineering team grows, there is a clear opportunity for this role to evolve into a leadership position, shaping the future of our QA team and practices.
Applicants should be prepared to attend our office in Shoreditch once a week.
