Mid-Level Software Development Engineer in Test (SDET)

This position is listed on behalf of a partner company, who manages all applications and next steps. Our partner is looking for a Mid-Level Software Development Engineer in Test (SDET) based in Brazil. This role is ideal for a software engineer with a strong quality mindset who wants to go beyond traditional testing and actively build the systems that ensure end-to-end product reliability. You will contribute to the development of a “glass-to-glass” validation platform that connects mobile applications, APIs, cloud services, and automotive simulators in a highly integrated environment. Rather than only executing tests, you will design and build automated testing frameworks that validate complex distributed workflows at scale. The position sits at the intersection of development, QA, and platform engineering, with a strong focus on automation, CI/CD, and system reliability. You will collaborate closely with backend, cloud, and DevOps teams to ensure continuous quality across fast-moving releases. This is a hands-on role where your work directly impacts the stability and trustworthiness of connected, real-time systems.
