Design and develop high-speed photonic components through optical modeling and experimentation. Collaborate with internal R&D teams to meet performance specifications and manage product transition to production.

Develop low-level embedded software for advanced networking products, working with Linux kernel components, user-space utilities, build systems, and hardware bring-up. Build scripts, test utilities, and development tools while participating in the full software development lifecycle, including testing, debugging, documentation, maintenance, and quality improvements.

Design and develop AI-enabled applications for Ciena’s Navigator Network Control Suite using generative AI, LLMs, classical machine learning, agentic AI, and RAG. Integrate AIOps capabilities, analyze datasets, train and fine-tune models, and build scalable microservice-based software. Responsibilities include code reviews, testing, deployment, AI technology research, and collaboration with cross-functional teams to improve network performance, automation, and operational efficiency.

Architects and validates next-generation coherent optical networking platforms from concept through deployment. Defines system requirements, optical protection architectures, high-speed hardware designs, and interactions across hardware, firmware, software, and management interfaces. Leads system integration, hardware characterization, modem validation, software bring-up, interoperability testing, and customer-use-case validation. Investigates complex technical issues, documents architectural decisions, and collaborates with engineering, product lifecycle management, and field teams.

Create and maintain structured DITA/XML content in AEM Guides and Sites; define metadata and taxonomy; develop Python automation and API/LLM integrations for tagging, summarization, ingestion, and validation; manage content lifecycle and governance; optimize content for discovery, reuse, and retrieval across DAM systems.

The Senior Software Engineer will develop embedded software for high-performance networking, collaborate with teams on development activities, and deliver technical documentation.

Lead the design of advanced high-speed analog circuits in CMOS technology, collaborating with teams on mixed signal IP blocks and characterizing analog circuits for optical solutions.

Develop and maintain embedded software, drivers, diagnostics, and tools for embedded CPUs, SoCs, Ethernet PHYs, FPGAs, and optical networking. Implement Linux kernel and user-space drivers, apply TCP/IP, VLAN, and memory management concepts, debug performance issues, and support board bring-up and BSP tasks. Collaborate with multidisciplinary teams and improve engineering efficiency with scripts and test utilities.

Manage accounts receivable aging, collections, customer follow-ups, billing disputes, payment reconciliations, and collection records. Collaborate with sales, customer service, and cash application teams to resolve discrepancies and improve processes. Prepare reporting on outstanding invoices and collection metrics, maintain process documentation, protect confidential information, and ensure compliance with accounting and billing requirements.

The Principal SI/PI Design Engineer will lead electrical package design for photonic and ICs, overseeing layout, optimization, simulations, and collaboration with cross-functional teams.

As a Digital Verification Engineer Expert, you will validate digital products, propose verification strategies, mentor team members, and ensure project timelines are met.

Design and validate system power and grounding and circuit-pack level power solutions for optical and Ethernet platforms. Create schematics and layouts, work with mechanical and supplier partners, verify prototypes with lab measurements, lead design reviews, mentor engineers, manage projects, and drive production handoff for power subsystems.
