Jobs at Mavenir

Deploys and integrates telecom software and hardware products for global customers. Performs integration testing, configuration changes, troubleshooting, and debugging in customer labs and live environments. Creates technical documentation, including procedures and design documents, and supports workshops, customer meetings, end-to-end delivery, and project lifecycle activities. Requires knowledge of cloud platforms, containers, Linux, virtualization, networking, scripting, telecom networks, and industry standards.

Designs, builds, and productionizes scalable AI systems spanning GenAI applications, AI platforms and gateways, Voice AI, LLM fine-tuning, model training, ML pipelines, and MLOps. Responsibilities include architecture, experimentation, backend API development, deployment, observability, monitoring, retraining, and continuous improvement of production-grade AI systems.

Monitor customer telecommunications platforms, manage incidents within SLAs, perform health checks, prepare reports, analyze monitoring alarms and service tickets, and communicate with internal support teams and customers. The role operates in a secured environment on 24x7, 12-hour shifts and requires basic Linux command-line skills, proactive problem-solving, willingness to learn, and strong English communication.

Develop and lead end-to-end QA strategy and architecture for 5G Session Management Function products. Design functional, API, performance, scalability, resiliency, chaos, security, network slicing, and QoS testing. Validate SMF interactions with core network functions and 3GPP compliance. Establish Kubernetes-based test environments, automation frameworks, CI/CD quality gates, KPIs, and release criteria while mentoring QA engineers and collaborating with product, development, DevOps, and architecture teams.

Provide end-to-end troubleshooting and support for packet core (4G/5G) in live customer networks, analyze call flows and signaling, collaborate with R&D and system teams, support VoLTE/VoWiFi/IoT services, engage with customers to drive resolution, and perform on-site or remote deployments with required travel.

Lead architecture and development of cloud-native 5G Packet Core network functions. Drive microservices-based design, 3GPP compliance, performance and packet-processing optimization, CI/CD and DevSecOps adoption, and mentor engineering teams while owning feature delivery, release execution, and production support.

Designs, develops, and tests Linux-based embedded software for USRP processing subsystems. Implements FPGA register access, HALs, device drivers, secure remote upgrades, and integrates UHD APIs/RFNoC. Manages SDR platform integration, radio initialization/calibration, IQ transport, and timing/synchronization (GPSDO/PTP/PPS). Develops high-performance Ethernet (10G/100G), eCPRI/O-RAN transport, and debugs packet latency and throughput.

Designs, develops, tests, and maintains Java backend applications, REST APIs, and scalable services. Responsibilities include database design, code reviews, automated testing, CI/CD integration with Jenkins, Linux deployment and troubleshooting, scripting, defect resolution, and technical documentation. Collaborates with QA, architects, product owners, and development teams using Agile and Scrum practices.

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.

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.

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.

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