Senior Machine Learning Engineer

Senior Machine Learning Engineer, Matching & Recommendations At Bumble, we’re building the Love Company — a place where healthy, equitable relationships and friendships can start and grow. Machine Learning sits at the heart of that mission, helping us understand what makes a meaningful connection and powering the matching, recommendation, and personalization experiences that bring people together.

As a Senior Machine Learning Engineer, Matching & Recommendations, you’ll help build and evolve the ML systems that power how members discover and connect with one another. You’ll work hands-on across recommendations, retrieval, ranking, personalization, experimentation, and production ML, partnering closely with Engineering, Product, Data Science, and Analytics to translate member needs into scalable ML solutions. You’ll own complex projects across the ML lifecycle — from modeling and evaluation through deployment, monitoring, and iteration — while contributing to a culture of technical excellence, curiosity, and responsible AI.What

you’ll do Build and deploy machine learning models that improve recommendations, ranking, and personalization, driving measurable impact on user experience and engagement

Own problems end-to-end, from data exploration and feature engineering through to model training, evaluation, and production deployment

Develop and maintain scalable ML pipelines using tools such as Spark and Airflow to support reliable, high-quality model delivery Apply modern ML frameworks (e.g. PyTorch or Tensor Flow) to design, train, and optimize models in production environments

Contribute to experimentation frameworks, including A/B testing and offline evaluation, to iterate on model performance with an agile mindset

Collaborate cross-functionally with Product and Engineering, working with purpose to translate product questions into ML solutions

Take ownership of delivering high-quality solutions and see work through from insight to impact, balancing speed and rigor

Apply responsible AI practices, ensuring fairness, transparency, and safety are considered in model development and deployment

About You Typically requires 5–8 years of experience, though we welcome candidates with alternative backgrounds that demonstrate equivalent skills.

About UsBumble Inc. is the parent company of Bumble Date, BFF, and Badoo. The Bumble platform enables people to build healthy and equitable relationships, through Kind Connections. Founded by Whitney Wolfe Herd in 2014, Bumble was one of the first dating apps built with women at the center and connects people across dating (Bumble Date) and friendship (BFF). BFF is a friendship app where people in all stages of life can meet people nearby and create meaningful platonic connections and community based on shared interests.

Badoo, which was founded in 2006, is one of the pioneers of web and mobile dating products.
