How is a customer transformed into an engaged user? Within the Loyalty & Virality Tribe, the relationship is maintained through technical excellence. The scope involves architecting the HelloFresh Rewards and Loyalty ecosystem, where the goal is to create a "sticky" experience that keeps members engaged.

This role involves collaborating with a high-cadence team focused on one primary goal: Loyalty Member ROI. The project focuses on building reasons for millions of users to engage with reward points, explore new products, and feel valued at every step of the journey—from the shopping funnel and beyond.

What You’ll Do: The Recipe

• Drive Loyalty ROI: Design and ship features across the Rewards domain that encourage members to earn, track, and—most importantly—spend their points.

• Full-Stack Flexibility: While the focus is React, the service includes contributing to React Native mobile experiences and engaging with Backend topics to ensure end-to-end delivery of features.

• High-Velocity Iteration: Maintain an aggressive development cadence, turning hypotheses into live experiments in day(s), not weeks.

• AI-Augmented Engineering: Develop usage patterns and tailor processes to enable optimal customer impact. This involves finding ways to utilize AI to automate tasks and accelerate code generation.

• Shape the Backlog: Drive the product direction. High-level contribution to the hypothesis backlog is expected, helping decide what is built based on data coming from customer behavior.

What You’ll Bring: The Ingredients

• Web Mastery + Mobile Curious: 5+ years of experience with React and TypeScript. You have a solid foundation in web, and either past professional experience with React Native or a hunger to apply your skills here
• "Full-Stack Ready" Mindset: You aren't afraid of the "black box" of the backend. You’re willing to jump into APIs and services to unblock yourself and the team.
• The Speed Factor: You thrive in environments with aggressive prioritization. You know when to build for the long term and when to build a "quick and dirty" experiment to prove a point.
• GenAI Savvy: You are already using AI tools to supercharge your workflow and are excited about pushing the boundaries of how AI can assist in product development and improving the customer experience

Cross-Funnel Thinking: You understand that "Loyalty" doesn't stop at the Rewards page—it lives throughout the user experience, in the checkout, the account settings, and the homepage.

Above all, we are looking for people who will make HelloFresh better. We believe there are many different ways of developing skills and we love diverse experiences. So even if you don’t “tick all the boxes” but think you’d thrive in this role, we would really like to learn more about you.

From meal kits and ready-to-eat meals to specialty offerings like pet food and premium meat & seafood, HelloTech creates the platforms that bring tailored food solutions to millions of customers every month.

Our subscription-based, direct-to-consumer model relies on technology at every step, from customer-facing apps and personalization logic to pricing, forecasting, supply chain optimization, and initiatives that help reduce food waste. While our brands operate independently to serve distinct customer needs, they are united by shared platforms, data, and operational excellence built by HelloTech.

HelloTech works in autonomous, cross-functional alliances, each owning a specific product or domain end to end. By working with our Warsaw office, you will help shape scalable, data-driven products used across our markets, working with a modern tech stack and international teams to continuously improve how people discover, order, and enjoy HelloFresh’s products, today and in the future.

About the role: What's in the Box

This position is for an expert in developing and deploying large-scale recommender systems.

This involves working closely with other personalization Data Scientists, as well as Data, Backend, and Machine Learning Engineers, to deliver statistical solutions and ML models to production. Success in this role requires a curious mindset, the ability to prioritize problem statements, and the expertise to suggest multiple solutions based on potential impact. This role does not include people management responsibilities.

At HelloTech, flexibility and cross-functional collaboration are core to how we work. While this role is aligned to a specific Alliance, strong candidates may also be considered for opportunities across different teams or projects.

What you’ll do: The Recipe

• Become an integral part of a high-impact team covering menu personalization.
• Contribute to designing and implementing the next generation of recommender models, from experimentation and data collection to operationalization.
• Shape the future of customer experience by proposing new personalization approaches and evolving statistical and ML models in pace with future company strategies.
• Design and execute A/B tests to measure the impact of new recommendation strategies on key metrics.
• Work with state-of-the-art technologies like AWS (EMR, Glue, S3, etc), Kafka, PySpark, Airflow, Databricks, MLFlow, and Claude (AI).
• Collaborate closely within other functions (data engineering, backend engineering, ML engineering, product) to translate business objectives into concrete strategies.
• Analyze the performance of models to understand customer behavior and implement technical improvements.
• Contribute to a collaborative and knowledge-sharing environment, providing technical guidance and coaching to team members and stakeholders.

What you’ll bring: The Ingredients 

• Proven track record of scientific work (Bachelor's, Master's, or PhD) in computer science, statistics, physics, economics, mathematics, or data science.
• 3+ years of work experience as a data scientist focused on developing and deploying recommender systems or personalized ML models in a production environment.
• In-depth knowledge of various recommendation algorithms, evaluation metrics, and the practical challenges of maintaining a modern recommender system.
• Fluency in Python, including high familiarity with its scientific stack (Numpy, Pandas, Scikit-learn, Matplotlib). Experience in Databricks and PySpark is a plus.
• Technical proficiency in SQL for retrieving, manipulating, and analyzing large datasets.
• Experience with software development practices and tools such as Git, CI/CD, Docker, and AWS.
• Expertise in leveraging Generative AI tools (e.g., Claude, Copilot) to support model development, experimentation, and documentation.
• Exceptional communication capabilities to interact effectively with product managers, UX designers, and business stakeholders.

Above all, we are looking for individuals who will make HelloFresh better. We believe there are many different ways of developing skills and we love diverse experiences! So even if you don’t “tick all the boxes” but think you’d thrive in this role, we would really like to learn more about you.
