Position Overview
We are seeking an experienced Software Development Engineer in Test (SDET)
to join our engineering organisation and operate as a core developer on quality. You will design and build the platforms, frameworks, tooling, and infrastructure that make our OSS/BSS systems (network provisioning, inventory, CRM, billing, charging, and mediation) testable, observable, and releasable with confidence at telecom scale.
Unlike a traditional QA role, you will spend most of your time writing production-quality software—test harnesses, simulators, data generators, CI/CD tooling, service virtualisation, and contributions into product code to improve testability. You will partner closely with backend, platform, and DevOps engineers, treat test infrastructure as a first-class product, and raise the engineering bar for quality across distributed, high-volume telecom services.
Key Responsibilities
- Design, build, and own end-to-end test platforms and frameworks for Java-based microservices, event-driven systems, and the GUI applications that sit on to
