Senior Software Engineer - Test Infrastructure

We are looking for a Software Engineer – Test Infrastructure to join our Release Engineering team. You'll be part of a cross-functional team whose mission is to lead IonQ on its journey to build the world's best quantum computers to solve the world's most complex problems.

In this role, you will own the quality signal for the integrated software that runs IonQ’s quantum computers. You will design and operate the automated testing that validates complete systems — from customer-scale circuit execution to the tools used to operate and calibrate the machines — on shared test environments that are themselves real quantum computing systems. You will build the CI infrastructure that catches integration problems early, set system-level test strategy, and manage the test system fleet that makes all of this possible, partnering daily with software, hardware, and physics teams.
