Enurgen builds DUET, a 3D physics-based software platform for utility-scale solar and battery storage. DUET simulates what a plant should produce at every timestep of a 30-year life, compares it against what the field actually did, and attributes the gap down to the individual component. Conventional monitoring can tell you a plant is underperforming — working out why is the hard part, and that's the problem we solve. Every megawatt-hour a solar plant fails to produce is one that comes from somewhere else. Recovering it needs no new land, no new panels, and no new interconnection queue — just a correct answer about what went wrong and where. The model came out of SUNLAB at the University of Ottawa, with more than a decade of research behind it. It runs across the asset lifecycle: - Design — terrain-aware 3D modelling to establish a realistic performance baseline before anything is built. - Construction — analysis from the moment equipment comes online, so issues surface before commercial operation rather than years into it. - Operations — minutely, string-level analysis with automated root-cause loss detection, separating recoverable losses from the ones that aren't and routing the fixable ones into the maintenance system. We're a small, early-stage team with an office in Ottawa, Ontario. The engineering work is heavy on data: analytical queries over fleet-scale time-series, streaming pipelines feeding live analytics, on-prem software that keeps running when the WAN doesn't, and dashboards that stay fast at that scale. Research sits at the same table as engineering, so the physics and the software get built against each other. Hybrid-first, with remote on the table for any role. Every role includes an equity grant. You don't need a solar background — the domain is interesting, our customers are sophisticated, and you'll pick it up.
