Job Title: Software Development Engineer in Test (SDET), OSS/BSS

Location: Pune, India

Reports To: Engineering Manager

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 top of OSS/BSS components.
Write production-quality code in Java (and supporting languages such as Python, Kotlin, or TypeScript) for test libraries, harnesses, SDKs, CLIs, and shared abstractions used across the engineering organisation.
Build simulators, stubs, mocks, and service virtualisation for upstream/downstream telecom systems (network elements, mediation feeds, charging gateways, payment systems) to enable deterministic, isolated testing.
Contribute directly to product code to improve testability—adding hooks, feature flags, contract definitions, observability, and clean seams between modules—as a peer of the backend developers.
Design and implement end-to-end automated coverage spanning APIs, backend services, databases, message queues, and GUI workflows for CRM, billing, mediation, provisio
