Top Tech Jobs & Startup Jobs in Toronto

Process full-cycle payroll using ADP Workforce Now, ensuring accurate wages, deductions, and off-cycle payments. Maintain employee payroll data, ensure compliance with Canadian payroll legislation, prepare reconciliations and reports (T4s, ROEs), administer benefits and deductions, assist audits, and generate custom payroll reports. Collaborate with HR and benefits providers and support system updates and testing.

Develop and optimize fabrication processes for integrated photonic devices (especially thin‑film lithium niobate). Own wafer lots with foundry partners, design and run process improvement experiments, perform metrology and failure analysis, collaborate across process and design teams, and implement new fabrication learnings to improve device performance.

Administer and integrate core SaaS and collaboration platforms, build and maintain NetSuite and other system integrations, automate workflows with scripting, manage user lifecycle and SSO, support macOS/Linux/Windows endpoints and hardware, triage and resolve support tickets end-to-end, maintain documentation and runbooks, and participate in on-call rotation.

The role involves designing and modeling photonic integrated circuits (PICs) for quantum computing, ensuring low insertion loss and low noise. You will collaborate across teams, utilize fabrication processes, and validate control performance.

Design and scale passive and active integrated photonic components for quantum hardware. Use high-throughput cloud simulation pipelines, execute DOEs and tapeouts, collaborate with Fabrication/Tooling/Test teams, perform data-driven analysis and optimization to achieve sub-milli-dB loss and transition designs to high-volume wafer production.

As a Quantum Scientist at Xanadu, you'll design and optimize quantum algorithms, develop compilation techniques for quantum circuits, and lead projects while collaborating across teams.

Develop and maintain control and measurement software that connects custom hardware (control boards, instruments, DAQ) to higher-level experiment frameworks. Write and integrate device drivers, support lab hardware bring-up and debugging, improve data capture and deployment practices, and contribute to tooling, testing, and CI to make prototype code reliable and maintainable while working closely with physicists and hardware engineers.

Own installation, maintenance, troubleshooting, and optimization of semiconductor and photonics fabrication equipment (CMP, bonding, metrology, lithography, deposition). Develop maintenance protocols, improve tool uptime, qualify new tools, manage spares and inventories, coordinate with facilities and manufacturing, ensure cleanroom compliance, and support factory/site acceptance tests including international travel.

The Lab Operations Specialist supports lab projects by maintaining equipment, performing technical tasks, troubleshooting, and documenting procedures while ensuring a clean and organized lab environment.

As a Photonics Data Analysis Engineer, you will develop software for analyzing and measuring photonic devices, requiring advanced mathematical skills and strong programming expertise, particularly in Python and data visualization.
