As a Senior QA Engineer, you will design test strategies and automation for optical networking solutions, ensuring quality and performance through manual and automated testing, and collaborating with engineering teams.

Develop and test embedded software and firmware for optical networking pluggable devices. Responsibilities include understanding optical systems, applying telecom standards and protocols, coding in C and C++, and maintaining Python-based automated testing and validation frameworks. The role involves debugging, collaborating with global teams, and working under supervision within established technical guidelines.

Design, implement, test, and debug firmware for next-generation optical line systems, including ROADM, EDFA, and Raman products. Develop requirements and design documentation, collaborate with hardware, FPGA, software, manufacturing, and test teams, support hardware bring-up and customer issue resolution, contribute to architecture and design reviews, and improve development processes. The role requires embedded C/C++ development in multithreaded real-time environments, Linux or RTOS device drivers, hardware interface knowledge, and strong troubleshooting skills.

Lead design and architecture of cloud-based systems, mentor architects and developers, translate stakeholder needs into technical solutions, optimize large-scale databases, conduct code reviews and performance tuning, document architectures, troubleshoot complex issues, and enforce security and best practices.

Architect, design, develop, and test mission-critical embedded software for Nokia optical pluggable devices. Own end-to-end architecture across hardware interfaces, MCUs, RTOS or bare-metal stacks, drivers, middleware, security, boot, and power management. Lead technical trade-offs, establish platform standards, validate solutions on hardware, drive product quality and reliability, and mentor engineering teams.

Creates and maintains structured technical documentation, user guides, API content, operational information, and web-based publications for optical networking products. Collaborates with R&D, product lifecycle management, and testing teams; manages documentation schedules; uses XML authoring, graphics, content management, defect-tracking, Agile, and DevOps tools. Ensures reusable, accurate, customer-focused content aligns with product releases, quality standards, and documentation development practices.

Leads firmware testing for carrier-class optical telecommunications products. Responsibilities include developing test strategies, executing white-box and black-box testing, creating automated test frameworks and optical performance test cases, debugging cross-functional issues, performing root-cause analysis, and supporting sustenance releases. The role requires extensive embedded telecom testing experience, Python automation, optical test equipment expertise, and technical leadership across geographically distributed teams.

Designs, writes, edits, illustrates, and publishes technical documentation and user guides for complex optical networking products and systems. Manages documentation schedules, collaborates with product, R&D, and testing teams, creates API documentation, and maintains reusable structured content. Uses XML authoring, graphic editing, content management, defect tracking, Agile, and DevOps tools to deliver accurate web-based documentation for internal and external users.

Design and maintain end-to-end test strategy, architectures and automated frameworks for telecom packet-core products. Plan and execute performance, scalability and functional tests, manage test environments, integrate tests into CI/CD, mentor offshore test teams, gather customer requirements, and present results to customers.

Supports optical networking presales by analyzing RFIs and RFPs, translating customer requirements into technically accurate responses, developing competitive solutions with sales teams, and coordinating with Product Lifecycle Management. Maintains a searchable technical content library and ensures proposals align with product capabilities and roadmaps. The role requires deep expertise in optical and packet transport systems, network management standards, multi-vendor interoperability, and technical presentations, while managing multiple projects and deadlines.
