Design, automate, and maintain scalable Kubernetes deployments and CI/CD pipelines. Build Docker images and Helm charts, integrate third-party tools (Vault, SealedSecrets, cert-manager, Multus), implement Jenkins automation for builds and testing, support lifecycle management, and collaborate with engineering teams to improve deployment reliability and automation.

Develops comprehensive test plans and executes end-to-end system testing for 5G Core Policy Control Function software. Responsibilities include reviewing 3GPP standards and architecture documents, designing test cases and fixtures, validating functionality, performance, and reliability, and collaborating cross-functionally to ensure requirements and test coverage. The role also involves test automation using Python or Bash in Docker and Kubernetes environments, with familiarity with cloud-native technologies, virtualized network functions, DevOps, and CI/CD practices.

The R&D Manager will lead a software engineering team to deliver telecom products, manage priorities, ensure quality and drive improvements, while coordinating with various departments.

Develops, tests, debugs, and troubleshoots cloud-native software systems for 4G and 5G wireless baseband Layer 1 applications. Requires proficiency in C and C++, with MATLAB and Python as preferred skills. The role involves working with Intel FlexRAN, CI/CD tools including Jenkins and GitHub Actions, and development tools such as GitHub Copilot and Visual Studio Code. Candidates need a relevant bachelor’s degree and 5–7 years of cellular wireless baseband experience.

Leads operational deployment, integration, and support of Access and Packet Core telecom solutions for mobile carrier customers. Coordinates with sales, product, engineering, testing, deployment, global support, and third parties to meet service-level agreements and operational readiness goals. Manages customer communications regarding roadmaps, releases, incidents, and performance while directing incident response, service restoration, root-cause analysis, secure network access validation, and multinational technical teams.

Design, develop, and optimize cloud-native backend, frontend, and AI-enabled applications across Azure and AWS. Build APIs and Angular applications, integrate LLMs, AI agents, RAG, document intelligence, and workflow automation, and manage SQL Server and MongoDB data solutions. Support Docker-based deployments, CI/CD, security, monitoring, performance optimization, and multi-environment operations. Develop Power Apps and Power Automate solutions while contributing to scalable system architecture and secure enterprise integrations.

The role involves supporting Oracle EBS R12 and EPM systems, providing technical guidance, production support, and training for finance users. Responsibilities include managing financial modules, resolving issues, and ensuring accurate EPM reconciliation.

Provide L2/L3 technical support for online charging systems and telecom infrastructure in a high-availability environment. Troubleshoot HTTP/2, REST, Diameter, and SS7 issues; conduct health checks, monitor stability, analyze KPIs and traffic, manage incidents, and maintain tariff products. The role requires Linux/UNIX, Shell scripting, Kubernetes, Couchbase, Elasticsearch, and Kafka expertise, plus participation in 24/7 shift rotations.

The Verification Engineer tests and validates software products, develops automated testing scripts, analyzes test results, and collaborates with development engineers.
