📋 Description

• Make Large Datasets Feel Light : Implement level-of-detail downsampling, viewport culling, sub-pixel zoom/pan, and time-aligned overlays at interactive frame rates on tablets • Render the PQ Vocabulary : Build oscillographic waveforms with cycle markers, RMS-vs-time strip charts, harmonic spectrum bars to the 50th order, phasor diagrams, harmonic heatmaps, CBEMA/ITIC tolerance curves, scatter/PDF plots, and event timelines • Design Analysis-Grade Interactions : Smooth pinch/scroll on touch, trackpad, and mouse-wheel; crosshair with multi-series readout; brush-to-zoom; synchronized cursors across stacked charts; drill-down on event markers • Get Visual Details Right : Color palettes that work on screen and print, accessible contrast, type and tick spacing respecting expert reading habits • Profile Relentlessly : Performance benchmarking and profiling to improve user experience and optimize metrics footprint • Ship Usable v1, Then Iterate : First cut of a new chart in a week, refined with team and real users in the open • Operate the Chart Engine : Share on-call rotation for rendering and performance regressions, turning each into a permanent benchmark

🎯 Requirements

• Custom Chart Engineering : Built non-trivial visualization beyond what off-the-shelf libraries can do not just configuration • Interaction-Design Instinct : Zoom, pan, brush, crosshair, drill-down—you know what good feels like and you've built it • Large-Dataset Performance Discipline : LOD downsampling, viewport culling, profiling tools, frame-time budgets on real lower-end devices • Visual Taste Plus Engineering Rigor : Equally comfortable in Figma and in a profiler • Operational Ownership : You expect to be on call for the rendering layer you build, including platform-specific regressions • Listener Mindset : You ask expert users how they actually read a chart before deciding how to draw it • Desirable (but not required): Prior data-viz heavy work: trading-desk frontends, BI tools (Tableau, Power BI), genomics/biomedical viz, or scientific software • Background in signal-heavy domains where waveforms or spectra are the primary medium • Golden-test or visual-regression experience for charts • Test-driven development as default practice for non-rendering portions of the chart engine

🏖️ Benefits

• Visualization-First Product : Charts are the core experience here, not a side panel • Specialist Team : Work alongside a dedicated power-quality analyst, lead architect, data-processing engineer, and hardware product teams • Real-World Dataset Complexity : Multi-channel, multi-phase, multi-aggregation-interval, gigabyte-scale recordings • Made-in-Germany Quality : Decades of measurement-instrument heritage with a customer base that notices when the numbers are right
