Mobile Data Visualization Engineer - Interactive Technical Charts Join Synmatch AI's client as a Mobile Data Visualization Engineer to build the chart engine where power-quality analysts will spend their day. Smooth zoom on a million samples, on a tablet or desktop. For a PQ analyst, the chart is the product. They live inside it for hours zooming from a week-long campaign down to a single half-cycle, overlaying multiple recordings, brushing across phases, reading harmonic spectra to the 50th order. Join Synmatch AI's client on the founding engineering team building the next generation of power-quality analysis software and own the visualization layer that makes all of that feel instant and effortless. Our client has decades of expertise in electrical safety, e-mobility, medical technology, power quality, and energy management systems. You'll create visualization experiences for smartphones and tablets that support field workflows and offline-first operations for professionals working with high-quality measurement technology. You'll work closely with a power-quality analyst on what a "correct" chart actually means in this domain. The Lead Architect sets the boundaries; the look and feel of every chart, you own. You build it, you run it: the chart engine you ship is the one you also profile in production, debug from field reports, and evolve as datasets grow. What you will do as a Data Visualization Engineer... 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 What we are looking for… 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 and perks… 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 Locations Bengaluru Remote status Fully Remote Employment type Full-time About Synmatch AI Synmatch AI was founded in 2025 to make global hiring fair, transparent, and accessible to everyone.
