Senior Back-End / Data Engineer – Innovation teamAbout UsPower Factors is accelerating the green energy transition by providing advanced analytics and AI insights to operators of renewable energy assets. Our SaaS platforms are used to manage over 250 GW of wind, solar, hydro, and energy storage projects globally. By driving down operational costs and increasing revenue, we are tackling one of the world’s most key challenges: making renewable energy the world’s leading source of power. Our vision is to create a sustainable world powered by renewable energy. Our mission is to fight climate change with code.About the RoleWe are looking for a Senior Backend Engineer to join the Innovation team— This role is the connective tissue of the. You will own the data foundation that makes state-of-the-art model training possible, the inference service that makes model outputs usable, and the platform integration that puts those outputs in front of pilot customers. From production ETL through to shadow-mode validation pipelines, you will be the engineer who keeps every track moving. The role is based in Montreal and is critical-path from day one.About YouYou are a senior backend engineer with serious data engineering chops and a track record of shipping production ML-adjacent systems. You have built pipelines that don’t just move data — they guarantee its quality, version it for reproducibility, and hold up under real-world operational chaos. You understand that a model is only as good as the data it trains on, and that an inference service is only as useful as the product it integrates into. You are energised by breadth and ownership, and you are comfortable carrying a heavy load on a small team where your decisions have direct programme-level consequences.Required Qualifications6+ years of backend and data engineering experience, with a proven track record of shipping production systemsProduction-grade ETL/ELT pipeline design at scale: idempotency, retry logic, backfill jobs, incremental loading, and cost-controlled warehouse computeSchema design and data modelling across heterogeneous sources — experience reconciling signals from disparate systems into a canonical, queryable formatData quality engineering: automated quality gates (sparsity, flatline detection, outlier flagging, freshness checks), alerting pipelines, and dataset versioning for ML reproducibilityAPI design and development:
