As a Senior Machine Learning Engineer focused on scalability and productionisation, you will bring advanced machine learning models to life in production, from content understanding systems that interpret profiles, photos and text, to recommendation models that shape every match. You will build and scale the pipelines, infrastructure and automation that transform experimentation into reliable, high-impact features for our members.

• Design, build and optimise ML pipelines and production systems that train, evaluate and serve recommendation models efficiently and at scale.
• Work in a cross-functional team alongside data scientists, machine learning scientists, software engineers and both technical and non-technical stakeholders.
• Partner with ML Scientists to translate research models into efficient, maintainable, and well-tested production systems.
• Implement monitoring, observability, and retraining strategies to ensure continuous model performance in a dynamic, global environment.
• Contribute to the evolution of our ML infrastructure, including CI/CD, model registries, and feature stores.
• Diagnose and resolve production ML issues, such as data inconsistencies and model drift, to identify and resolve infrastructure bottlenecks.
• Champion engineering best practices for scalability, reliability, and reproducibility across the ML lifecycle.

• 5 years of relevant industry experience.
• An advanced degree in Computer Science, Mathematics or a similar quantitative discipline.
• Strong software engineering background. You write clean, scalable, and maintainable code in Python or similar languages.
• Proven experience deploying and operating ML systems in production environments.
• Deep understanding of MLOps and infrastructure concepts: CI/CD for ML, feature stores, model serving, observability, and versioning.
• Experience with modern ML frameworks (e.g. PyTorch, TensorFlow) and orchestration tools (e.g. Airflow, Kubeflow, SageMaker, Ray).
• Familiarity with containerisation and cloud-native environments (e.g. Docker, Kubernetes, GCP/AWS).
• Skilled at debugging complex, distributed ML systems and optimising for performance at scale.
• Excellent communicator and collaborator. You communicate effectively with scientists, engineers, and non-technical stakeholders.
• Interested in contributing to the responsible development of ML and AI, with a focus on building systems that are fair, equitable and accountable.

• Own meaningful projects that directly impact millions of Bumble users.
• Learn and grow in a high-performing engineering team committed to mentorship and learning.
• Be part of a culture that values respect, excellence, curiosity, courage and joy.
• Enjoy competitive compensation, equity, and world-class benefits.

AI in Bumble Inc. Hiring 

At Bumble, we may use AI tools to support parts of our recruitment process — such as helping us record, transcribe, and summarize conversations, and supporting job alignment by comparing resumes and job descriptions to highlight skills and potential roles that may be a good match. These tools help us work more efficiently and stay focused on you during our conversations. Importantly, all hiring decisions are made by people. AI is used only to support our team’s efficiency and improve the candidate experience — not to evaluate or decide on your candidacy. Participation in AI-supported interviews and conversations is completely voluntary and will not impact your candidacy. If you’d prefer to opt out, simply let your recruiter or interviewer know at the start of a call, or anytime during the interview or conversation. Summaries and related data are retained only as long as needed in line with our internal data retention policies. If at any point you’d like a transcription or summary deleted, please contact your recruiter directly.
