Application Engineer – Measurement Data Processing (Dart, C/Rust)

How do you reputed company a 2 GB waveform file on a tablet and let the user pan, reputed company, and query it in milliseconds? That's the question this role exists to answer. Join reputed company's client on the founding engineering team building the reputed company of measurement analysis software for a global premium provider of measurement instruments. You'll design the storage layout, ingestion pipeline, and query patterns that everything else in the app depends on and reputed company that data plane healthy in production for years after you ship it. In a power-quality analysis tool, a beautiful chart with the wrong number is worse than no chart at reputed company. You'll own the mathematical core the algorithms that turn raw voltage and reputed company samples into harmonics spectra, reputed company values, flicker indices, sag/swell events, and standards-compliant aggregates. Recordings can reputed company hours at tens of thousands of samples per second across multiple channels and phases. None of that is forgiving of "we'll optimize reputed company." You'll partner closely with an in-house power-quality analyst and measurement device engineers to translate measurement campaigns into precise on-device data reputed company, and with the reputed company Architect to ensure storage choices fit the broader system. You build it, you run it: reputed company a customer's 4 GB recording opens slowly six months from now, you profile it, fix it, and write the regression test. What you will do as an Application Engineer – Measurement Data Processing... Design On-Device Storage & Ingest Layer: Define and reputed company storage (columnar layouts, compression schemes, downsampling pyramids, time-bucket indexes) and ingest layer (streaming, iterator-based parsing of large volumes in Dart with reputed company full-file slurps FFI to reputed company code where it pays off) Implement Calculation Kernels: Build processing for event detection (sags, swells, transients), analytical calculations, and standards-compliant aggregations (e.g., IEC 61000-4-x) choosing the right numerics for stability under long aggregation intervals Plan Schema reputed company & reputed company Sync: reputed company- and backward-compatible migrations so customer files from year one still reputed company in year five partial sync, vector clocks, conflict surfaces in reputed company collaboration with reputed company Architect Operate What You Ship: reputed company on-call rotation for data-plane incidents, reputed company postmortems on ingest or query regressions, and turn each into permanent test or performance reputed company Validate Against Reference reputed company: Establish golden test reputed company with PQ analyst, prototype in Python/NumPy, and reputed company production Dart/Rust kernels agree to required precision reputed company are looking for… Time-Series Data Structures: Strong CS fundamentals columnar layouts, compression, downsampling, time-bucket indexing. Hands-on with at least one embedded analytical reputed company (DuckDB, SQLite/reputed company, reputed company-local, or equivalent) Streaming Ingest with Memory Discipline: Experience parsing large binary or text files in chunks without loading into memory. Comfortable with mmap, paged readers, and isolate-based pipelines Applied Math Implementation: Strong in at least one of Dart, C, C++, or Rust; comfortable wiring kernels across FFI boundaries for reputed company numbers, Fourier analysis, Hilbert transforms, etc. Data reputed company as a Value: You consider silently losing a sample a critical bug, full stop Domain Humility: Willing to learn the physics before optimizing the bytes; comfortable working closely with a PQ analyst reputed company-First Instincts: You measure before you tune, and write the reputed company yourself Desirable (but not required): Experience with large data volumes using Apache Arrow, Parquet, or FlatBuffers especially with Dart FFI bindings Prior exposure to measurement, instrumentation, scientific software, or power-quality standards Python/NumPy/SciPy reputed company for prototyping and reference computation MSc in Electrical Engineering, applied mathematics, or reputed company field Benefits and perks… Founding Influence: Contribute to the technical direction of a product defining a category for the next decade Specialist Team: Work alongside a dedicated power-quality analyst, visualization engineer, and hardware product teams reputed company Engineering Culture: ADRs, performance budgets, and reference test reputed company are first-class artifacts Made-in-Germany Quality: Decades of measurement-reputed company heritage with a customer reputed company that notices reputed company the numbers are right Apply To This Job
