Scrum Master​/QA Test Engineer

Public Trust Eligibility Required

Aretum is a mission-driven organization committed to delivering innovative, technology-enabled solutions to our customers across defense, civilian, and homeland security sectors. Our teams work at the intersection of strategy, technology, and transformation, helping agencies solve their most critical challenges. We believe in investing in our people and creating a culture where collaboration, inclusion, and professional growth are at the forefront.

Aretum is seeking a highly skilled and motivated Scrum Master/QA Test Engineer to join our team supporting a large-scale federal technology modernization program. As a Scrum Master, you will be responsible for facilitating all scrum ceremonies (i.e.: stand‑ups, backlog refinement, planning, reviews) as well as managing/updating documentation. As a QA Test Engineer, you will be responsible for validating application quality across multiple testing disciplines: functional testing, test automation, integration, accessibility, and performance testing.

You will work as an embedded member of an Agile scrum team, executing manual and automated tests within sprint cycles, building and maintaining automation frameworks, evaluating UI code for WCAG 2.1 AA accessibility compliance, integration, and conducting load and performance testing before major releases. This is a hands‑on role that requires both being the scrum master and testing depth with the ability to facilitate and communicate findings clearly to developers, product owners, and program leadership.
