Top Tech Jobs & Startup Jobs in Toronto

Develop and own embedded software features for synchronization and timing on service router products. Design, implement, unit test, and integrate timing components; collaborate with HW, QA, product management, and vendors; troubleshoot hardware-software issues; ensure fault tolerance, high availability, and code quality for real-time, high-performance Linux-based systems.

Provide fourth-level IP network support and debugging for escalated customer issues, coordinate with R&D and support teams, perform on-site adaptations, maintain problem records and release notes, and support product reliability and test environments across global teams.

As a Senior Digital Hardware Design Engineer, you will design complex PCBs, manage the design process, verify prototypes, and resolve customer issues.

Design and develop mechanical enclosures and packaging for telecom electronics using PTC Creo and Windchill. Develop thermal solutions, design sheet metal/plastic/die-cast components, integrate PCBs, support prototyping, testing, qualification, and prepare engineering documentation while ensuring compliance with Telcordia, ETSI, and regulatory standards.

The HW Test Engineer defines test strategies and develops automated test solutions for manufacturing network equipment. They analyze quality issues, optimize test applications, provide training, and support development teams.

Design and implement carrier-grade embedded real-time firmware for optical line systems. Collaborate with hardware/FPGA and optical engineers to develop low-level device drivers, control algorithms on Linux/FreeRTOS, and gRPC-based interfaces. Provide design estimates, follow development processes, and sustain legacy products while supporting new product development.

Support NPI and sustaining engineering for routing hardware by managing product data, change control (ECO/MCO/Stop Orders), and BOM health. Develop custom queries, adapt SQL/Sequel for evolving product structures, implement data models, and create PLM workflows while coordinating across hardware, software, and product line management.

Lead standardization strategy for optical transport and Ethernet technologies, develop and advocate contributions to standards bodies (ITU‑T, IEEE, OIF, OpenROADM), coordinate with PLMs and R&D, report progress internally, provide technical influence and guidance, and represent Nokia at standards meetings and industry events.

Lead architecture and design of DWDM/OTN optical transport systems, translate customer requirements into system and functional specifications, guide cross-functional teams, produce detailed architectural documentation, and ensure alignment across hardware, software, verification, and documentation for carrier-grade networking products.

Design, model, and test high-speed electrical interconnects for optoelectronic modules. Collaborate with PIC, ASIC, TROSA, and module teams to define requirements, design RF structures, develop test vehicles, coordinate fabrication with vendors, and perform high-speed measurements and data analysis to advance next-generation optical module products.
