Role & responsibilities

- Design, build, and maintain automated test suites for OSS services provisioning and service activation, fault management, performance management, configuration management, and network/service inventory.
- Own end-to-end and integration testing across OSS microservices and the interfaces to the NTN core, gateways, and network elements.
- Validate service assurance flows — alarm handling, event correlation, KPI/performance collection, and SLA monitoring.
- Build and extend test automation frameworks (API, service, and data-layer) and wire them into CI/CD so quality gates run on every change.
- Validate integrations and data flows between OSS systems and network elements, including API contracts, event/message flows, and data consistency.
- Define test strategy and coverage for new OSS features, working with engineers and product from design through release.
- Investigate failures across distributed systems — trace issues through logs, message queues, and databases, and drive them to root cause.
- Contribute to non-functional testing (performance, resilience, data integrity) for high-throughput provisioning and monitoring flows.
- Mentor engineers on test design and quality practices, and help raise the bar for the team.

What you'll bring

- 5+ years in QA / test engineering, with meaningful time testing telecom OSS systems (provisioning/activation, fault or performance management,



service assurance, or network inventory).
- Strong test automation skills in Python and/or Java, with frameworks such as pytest, TestNG, REST Assured, or Selenium.
- Solid API testing experience (REST, Postman/Newman) and comfort validating contracts between services.
- Working knowledge of SQL and relational databases, and experience validating data across systems.
- Experience testing microservices and event-driven architectures (e.g., Kafka or similar messaging).
- Hands-on with CI/CD pipelines (GitLab CI, Jenkins, or similar) and integrating automated tests into them.
- Solid debugging instincts across distributed systems and a habit of driving issues to root cause.
- Clear communicator who can work across engineering, product, and network teams spanning multiple time zones.

Nice to have

- Familiarity with 3GPP / NTN or cellular core network concepts (5G core, network functions, service activation).
- Exposure to TM Forum Open APIs or standard OSS reference models (FCAPS, service assurance frameworks).
- Experience with network monitoring, alarm/event correlation, or telemetry pipelines.
- Performance and load testing experience (JMeter, k6, Gatling, or Locust).
- Containers and orchestration (Docker, Kubernetes) and cloud platforms (AWS or GCP)
