Staff Machine Learning Engineer - Pricing & Revenue (m/f/d)

Your Role You will take on technical leadership and end-to-end ownership for our Pricing/Revenue-ML topics—with a clear focus on measurable impact. You will work closely with Product and Engineering, define measurability/experiments, and ensure that our models not only “look good” but also perform reliably in practice. Important: No disciplinary personnel responsibility. You lead through expertise, standards, and ownership. Your Responsibilities End-to-End Ownership: You are responsible for the entire lifecycle of pricing and revenue topics—from hypothesis to implementation to measurable evaluation. Your focus: Clear business uplift. Smart Modeling: You develop and optimize forecasting and pricing models. You pragmatically decide which method gets us to the goal fastest and most stably. Signal Expertise: You manage time series, demand signals, and heterogeneous data sources. You ensure that features and labels are defined absolutely clean and “leakage-proof.” Experimentation Framework: You build a robust measurement system (holdouts, A/B tests, guardrails) and define crystal-clear criteria for rollout decisions. Engineering-Grade ML: You establish standards for backtesting, reproducibility, and versioning. For us, it's: Engineering quality instead of notebook-only. Reliable Operations: You ensure operations through smart monitoring, drift detection, and pragmatic retraining mechanisms. Automation & Scale: You automate high-leverage processes (backtests, monitoring checks) to massively increase throughput and quality. Data Foundation: Where it makes sense, you design data models directly in the warehouse (Snowflake/dbt) as a basis for reliable metrics and features. Full Transparency: You standardize dashboards (e.g., Metabase) for our business KPIs and ensure the data quality is beyond reproach. Stakeholder Sparring: You prioritize requirements together with Product & Revenue and translate them into ML solutions. Your motto: Impact over output. Your Profile Deep Experience: You have 5+ years relevant experience in ML Engineering, Data Science, or Analytics (or an equivalent track record that convinces us). Proven Impact: You have already achieved demonstrable success in the areas of pricing, revenue, forecasting, or similar “money systems.” Evaluation Pro: You think offline vs. online, immediately recognize bias/leakage, and master the fundamentals of robust metrics and guardrails. Tech Stack: Your Python and SQL skills are production-level (testable, versioned, reproducible). Startup DNA: You love the 80/20 principle, work extremely pragmatically, and want full ownership for your topics. Language Skills: You communicate fluently in German and confidently in English. Bonus Points (Nice-to-haves) Domain Knowledge: Experience in revenue management or dynamic pricing (e.g., travel, mobility, eCommerce). Demand Understanding: You know how seasonality, events, and lead times affect pricing. Modern Toolchain: You are proficient in analytics engineering (dbt, Snowflake, Metabase) and know how to build a clean data foundation.
