Job Description
Machine Learning Engineer
happyhotel
• Model Evolution: You develop and optimize our forecasting and pricing models as well as data-driven decision logics, always methodically pragmatic and fully impact-focused. • Signal Hunting: You work with time series, demand signals and heterogeneous data sources. You define features and labels so cleanly that leakage has no chance. • Measurement & Guardrails: You are responsible for evaluation through backtests, robust metrics and segmentations. You support holdouts and A/B setups and ensure the checks between offline and online performance. • Data Visibility: You build dashboards and reports that make model and business KPIs transparent. Your focus is always on the highest data quality. • Smart Workflows: You drive reproducible workflows (versioning, clean pipelines, meaningful tests) and automate recurring analyses and evaluation runs.
Job Requirements
- 2–4+ years of experience in Data Science, Analytics or Applied ML — ideally directly in a product or business context.
- Extremely strong SQL skills and a keen sense for data quality, debugging and consistent metrics.
- Your Python code is clean and your analyses are reproducible and well-documented. Initial experience with production-adjacent setups is a strong plus.
- Solid understanding of bias/leakage awareness and how to design guardrails and reason about offline vs. online scenarios.
- Full ownership of your topics. You work according to the 80/20 principle (pragmatic!), are reliable and communicate very clearly.
- You think entrepreneurially and want to make a real impact.
- You speak German fluently and have good English skills.
