Top Tech Jobs & Startup Jobs in Toronto

Develop software, AI-assisted tools, simulations, analytics, and decision-support algorithms for subsea optical communication systems. Optimize EDFA and Raman backhaul links, assess cable aging, recommend remediation and retesting, automate cable upgrades, and support commissioning and network operations. Collaborate with optical, systems, DSP, and software engineers, interface with customers, demonstrate solutions, and evaluate AI-generated code for correctness, scalability, and maintainability.

Architects coherent optical pluggable products for packet-optical telecommunications systems. Defines product requirements, system and software architecture, and technical specifications while balancing cost, capacity, performance, and functionality. Leads cross-functional teams involving ASIC, optical, hardware, and software engineers; evaluates customer requirements and feature feasibility; validates link-level control algorithms and optical performance monitoring; and documents product architecture and operational concepts. Requires extensive optical transport experience, advanced education, and strong knowledge of OTN, Ethernet, MACsec, CMIS, C-CMIS, and industry standards.

Architect Layer0 network element software for DWDM optical line systems, including ROADMs and amplifiers. Own requirements, architecture specifications, interfaces, data models, control algorithms, and acceptance criteria from concept through release. Lead cross-functional feature teams, guide development and validation, support customer engagements and field issues, and mentor engineers. Apply optical networking standards and technologies across L0/L1 systems while balancing cost, capacity, performance, and reliability.

Design and develop silicon photonics integrated circuits and optical engines for coherent optical transport systems. Lead PIC architecture, link budget optimization, device characterization, design verification, design-for-test, and design-for-manufacturing activities. Collaborate across photonics, RFIC/EIC, DSP, packaging, product engineering, foundry, and testing teams. Apply optical engineering, RF testing, programming, and physics expertise to deliver high-performance, manufacturable photonic solutions.

Leads strategic procurement for outsourced hardware development and manufacturing programs. Develops sourcing strategies, negotiates commercial agreements, manages ODM/JDM and contract manufacturing partners, supports NPI and product launches, drives cost reduction, and mitigates supply chain risks. Partners with engineering, product, quality, program management, and operations teams to optimize manufacturability, capacity, quality, delivery, technology, and supplier performance across the product lifecycle.

Leads quality assurance initiatives as a hands-on senior test automation engineer and functional manager. Develops test strategies covering end-to-end automation, scale, soak, regression, and chaos testing. Uses device simulators, hardware devices, and traffic generators to validate distributed-system resilience and stability. Collaborates across engineering teams, analyzes test results, mentors team members, and drives continuous improvement in testing processes and quality practices.

Develop and execute optical hardware and system-level validation tests. Improve Python-based test automation, workflow pipelines, data collection, and reporting. Interface with optical test instruments, investigate software and hardware failures, and perform root cause analysis. The role also involves applying AI-assisted coding tools and collaborating on optical integration and validation activities.

Manages the end-to-end procurement lifecycle for a category at Nokia, including category strategy, supplier selection and development, RFx processes, contract and price negotiations, supplier performance, risk mitigation, compliance, ESG initiatives, and KPI reporting. The role builds stakeholder and supplier relationships, drives savings, conducts business reviews, and ensures contractual and procurement obligations are met.

Develop and test firmware for next-generation optical network equipment using embedded CPUs within custom ASICs. Collaborate with Scrum teams on feature definition, coding, acceptance criteria, and unit testing. Apply knowledge of digital signal processing, control theory, optical networks, optical components, and embedded systems. Mentor interns and co-op students.

Leads enterprise-wide strategy execution, operating rhythms, performance management, and transformation initiatives. Partners with senior leaders across product, engineering, manufacturing, supply chain, finance, sales, HR, and corporate development to align priorities, improve organizational effectiveness, manage strategic programs, support growth and M&A activities, and provide data-driven executive decision support.
