About the role

We're excited by people who are curious and experimental, and who think thoughtfully about how AI can amplify their impact and outcomes.
We encourage you to use AI responsibly as you prepare your application.
Please don't use it to fabricate experiences or answer questions live in interviews.

Build and deploy production AI Agents using raw and fine-tuned foundational Large Language Models (LLMs), along with sub-agents, tools, and MCP integrations
Drive experimentation frameworks, including A/B testing and offline evaluation, to continuously improve model performance and product outcomes
Partner cross-functionally with Product, Engineering, and Data leadership to translate business challenges into impactful ML solutions, collaborating with purpose and influencing at senior levels
Expertise in prompting and fine-tuning Large Language Models (LLMs) and building production AI Agents
A track record of mentoring and uplifting others, role modelling Respect and Excellence while building inclusive, high-performing teams
Strong AI fluency, with the ability to independently design, evaluate, and optimise ML systems, and guide others in the responsible and effective application of AI
AI is used only to support our team's efficiency and improve the candidate experience - not to evaluate or decide on your candidacy.

Typically requires 10-15 years of experience, though we welcome candidates with alternative backgrounds that demonstrate equivalent skills.
Strong proficiency in Python and at least one major ML framework (e.g. PyTorch, TensorFlow), with experience in areas such as recommendation systems, ranking models, or NLP
Proven experience designing scalable data and ML pipelines using tools such as Spark, Airflow, or similar distributed systems
Demonstrated ability to operate as a senior individual contributor, influencing technical strategy and decision-making without direct authority
Experience partnering effectively across functions, collaborating with purpose and taking ownership of outcomes in complex organisational environments

Bumble 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.
We care deeply about authenticity and want to understand your real skills, judgment and voice, because building a meaningful, genuine connection with you matters to us.
Will be determined based on factors such as the selected candidate's qualifications, relevant experience, skill set, and other job-related considerations.
AI is important to us.
