(Senior) Machine Learning Engineer, Revenue Management (m/f/d)

Description

Machine Learning Engineering at the company turns models into systems that decide prices, forecast demand, and steer a fleet of hundreds of thousands of vehicles, millions of times a day. You build these systems with our Data Scientists, run them in production, and shape the ML platform while it is still being built. The numbers you move are real. Transform the way the world moves, because people expect better. Join Team Orange in Lisbon.

YOURS TO OWN

You build ML systems together with Data Scientists, from the first design session to the validated outcome in production. One team, one goal

You own design and architecture: how features are computed once and served consistently, how predictions flow out, how training, serving, and retraining fit together

You get models live safely - offline evaluation, shadow runs, champion/challenger, rollback. You run what you ship

You make quality structural - you define what a healthy ML system looks like, encode it as automated checks and alerts, and root cause issues so they do not recur

You are the bridge to MLOps - you bring the team's needs to the platform, bring platform standards back into the team, and co-own the templates and tooling that make the next use case faster

You multiply the team - setting the engineering bar, design how coding agents execute the ML lifecycle from data preparation to deployment, and grow production practice together with Data Scientists

YOUR SKILLS MATTER

Experience You have shipped and operated ML systems in production for 3+ years and know where they break: training/serving skew, leakage, drift, silent degradation

Software Engineering You are fluent in Python, SQL and one more language such as Go or Java: you read, review, and debug production code with confidence, whatever agent wrote it

ML Systems Design You design clean contracts between data, model, and consumers and reason about latency, cost, and failure

ML Fundamentals You understand forecasting, regression, and optimization well enough to challenge a model design and to recognize a wrong model in production

Software Factory You define acceptance criteria, orchestrate coding agents for implementation, QA, and security, and step in where they fall short. You review outcomes, not keystrokes, and want to shape how a team works this way

Platform Containers, orchestration, CI/CD, and model registries are daily tools. You have worked hands on in a major cloud platform, ideally AWS. Infrastructure as code is a plus

Team Spirit You act as a partner to Data Science, Product and Engineering, not a ticket executor: you challenge unclear framing, explain trade offs in business terms, and communicate fluently in English across cultures

Our mobility platform ONE combines our products the company rent (car rental), the company share (car sharing), the company ride (taxi, ride, and chauffeur services), and the company+ (car subscription), giving our customers access to our fleet of 360,000 vehicles, the services of 4,000 cooperation partners, and around 5 million drivers worldwide. At the company, top-tier customer experience and outstanding customer service are our highest priorities. We believe in true entrepreneurship and long-term stability and align our corporate strategy with foresight. Get started with us and apply now!
