Diagnostic Physicist, Thomson Scattering

About Daedal Systems Daedal Systems is a plasma diagnostic company for the fusion energy industry. Today, every fusion company needs the same R&D plasma diagnostics, but each company builds them themselves in-house, despite them not being core IP. Daedal Systems is building a platform for industrialized plasma diagnostics, which will enable us to deploy suites of plasma diagnostics on fusion devices across the industry. Ultimately, we will provide the operating infrastructure for every fusion power plant. We are seeking talented individuals spanning plasma diagnosticians, engineers and operators to join us in this mission to accelerate fusion energy with industrialized plasma diagnostics. We are building the measurement infrastructure layer upon which fusion will be realized. The Role Daedal Systems is looking for a Diagnostic Physicist to lead the design, deployment, and operation of Thomson Scattering diagnostics, a key system within our industrialized plasma diagnostic platform. Reporting to the Vice President of Science, you will be the senior technical authority on Thomson measurement, and be responsible for bringing Thomson Scattering diagnostics from low TRL, bench-top systems to industrialized, deployable systems. These systems will then be integrated on fusion devices across the industry. Education Master's degree or higher in physics, engineering, or a related field, or equivalent practical experience Essential Requirements Demonstrable track record designing and deploying Thomson scattering diagnostics on MCF fusion devices, measuring electron temperature and density profiles Experience developing detailed diagnostic specifications that translate physics measurement requirements (e.g. Te, ne, spatial and temporal resolution) into achievable instrument performance Direct experience with Thomson scattering subsystems: high-power pulsed laser systems, polychromators/spectrometers, and fast, low-light detectors (e.g. ICCD, streak camera, or avalanche photodiode arrays) Experience with calibration techniques for Thomson scattering systems (e.g. Raman calibration for absolute density calibration) Experience taking a diagnostic through its full lifecycle: design, procurement, build, test, installation, commissioning, calibration, operation, and maintenance Ability to operate independently as a technical lead with minimal supervisory structure Based in Toronto or willing to relocate — relocation support will be provided Comfortable with travel to support client systems around the globe, up to 20% of the time, occasionally for 2+ weeks in a row Desirable Experience at a startup or early-stage technical organization Publications involving Thomson Scattering diagnostics Experience with high-speed data acquisition, timing, and synchronization systems for pulsed diagnostics What You Can Expect You will join as one of Daedal's first technical hires and have the opportunity to shape the measurement infrastructure that will be applied across the fusion industry. The role carries significant autonomy, and you will own your discipline and lead Thomson Scattering deployments from concept design to implementation and ongoing operational support. As an early technical lead, you will also help shape the overall technical direction of Daedal's industrialized plasma diagnostic platform. What We Offer Annual salary range: 150k-250k CAD Compensation range shown is indicative; final salary and total compensation will be tailored to the candidate's experience and fit. Significant equity ownership in an early start-up Immigration and relocation support Opportunity to lead a key diagnostic and shape the company's technical direction Health benefits Daedal Systems is committed to an accessible and inclusive recruitment process. Accommodation is available upon request for applicants with disabilities throughout the recruitment, assessment and selection process. Please let us know if you require accommodation, and we will work with you to meet your needs.
