Job description

This is a remote position.

We’re hiring an intermediate Data Analyst / ML Engineer to grow our sim racing apps data-driven telemetry analysis features. You’ll turn raw laps into actionable insights – building data pipelines, training/evaluating models, and shipping them into production.

You’ll work primarily in C# Entity Framework Core (code‑first) with MSSQL on the server and SQLite in the app, surfacing insights in our Blazor / WPF UI. Expect clear goals, fast feedback, and close collaboration with the CTO.

What You’ll Do

• Build end-to-end data features: ingest, clean, transform and persist telemetry (laps, sectors, throttle / brake, steering, RPM, etc.)
• Develop models for driver coaching: lap alignment, pace deltas, consistency scoring, anomaly / outlier detection, stint / session segmentation
• Move prototypes to production (batch and near‑real‑time inference) using C#
• Implement backend services with EF Core (code‑first)
• Server: MSSQL (schema design, migrations, performance tuning)
• App: SQLite (lightweight schemas, efficient queries, migrations)
• Expose analytics via APIs and integrate results into Blazor / WPF dashboards and overlays
• Add data quality checks, validation and observability (metrics, logging, tracing)
• Write integration tests, keep CI / CD green, and document datasets, features, and experiments
• Participate in code reviews; follow and improve coding standards

What You Bring

• 3 years total experience with solid C# / .NET backend skills
• Practical experience (regression / classification / clustering, time‑series a plus)
• Proficiency with EF Core, LINQ and code‑first workflows across MSSQL (server) and SQLite (app)
• Ability to design features, evaluate models (cross‑validation, proper metrics) and ship to production
• Comfortable with Git workflows, integration testing and CI / CD

Nice to Have

• Signal processing for telemetry (resampling, smoothing, filtering)
• Real‑time / near‑real‑time analytics, caching and background workers
• Visualization skills for comparative laps and telemetry overlays
• Experimentation (A/B) metric design (pace / consistency indices)
• Interest in sim racing or motorsport
