About the Job

Requirements

  • You are preparing an engineering diploma or a master's degree specializing in data engineering, computer science, data processing, or scientific computing.
  • You can understand a complex business process, formalize it, and translate it into data structures and transformation rules.
  • You are proficient in Python and structured-data manipulation, including working with CSV and JSON files.
  • You have the ability to synthesize information, communicate, and explain technical concepts across multiple teams.
  • You demonstrate autonomy and initiative.

Responsibilities

  • Analyze test procedures with business stakeholders and represent their steps, loops, phases, and execution conditions clearly.
  • Identify the information needed for test result analysis and elements that can be standardized across procedures.
  • Document the links between test execution and expected results.
  • Explore test exports, including JSON files, CSV files, and summary files.
  • Map test business concepts to raw export representations, including tested cell or object identifiers, steps, loops, time, measurements, and test conditions.
  • Propose a data dictionary and conventions for naming, units, aliases, and tags to facilitate source-data use.
  • Develop the data-reading, normalization, and consistency-checking processes required.
  • Translate result-analysis methods into explicit specifications and reusable, configurable processing routines.
  • Select relevant test steps, loops, phases, and portions of curves.
  • Contextualize each calculation with its state of charge, current rate, charge or discharge direction, temperature, and other relevant conditions.
  • Implement formulas, regressions, or integrals defined with subject-matter experts.
  • Incorporate tolerances, warnings, and handling of non-calculable cases, and test against reference datasets.
  • Build a catalog of analysis methods detailing input data, selection rules, result granularity, calculation method, units, validity conditions, and business references.
  • Define and produce standardized analytical tables that business users can use directly.
  • Develop use cases for electrochemical characterizations and results by sample, state of charge, current rate, charge or discharge direction, duration, and temperature.
  • Attach validation status and traceability information to results so source data and applied methods can be identified.
  • Structure code and parameters for maintainability, reuse, and extension to additional analyses.
  • Design standard business-facing views from analytical tables, including curves, comparisons, and filters by sample, method, or solicitation direction.
  • Verify with users that reports meet their analysis needs.
  • Document the data model, calculation methods, and validation rules.
  • Prepare usage examples and onboarding materials to support transfer of laboratory know-how.
