Were a team of around 250 people and to take the next step were looking for an experienced and hands-on Senior Data Scientist (all genders) to bring machine learning into the heart of our product.

As a Senior Data Scientist you will build Aroundhomes first machine learning model in production: the logic that decides which partners each homeowner is matched with. You will start from the problems homeowners and partners actually have and own the solution end to end in a small new team with a product manager an engineer and the team lead.

• Start from the Customer: Understand what homeowners and partners need from a match and turn that into the outcomes and guardrails your models optimize for not just model metrics.
• Own Our Matching Models: Build and run the models behind our partner matching end to end: data features training evaluation deployment and monitoring.
• Make Every Match Count: Improve our matching logic with deployed models that make the most efficient use of partner capacity raise match rates and account for regional supply and demand.
• Prove Impact: Measure every improvement against our current logic in controlled experiments designed for a two-sided marketplace before it scales.
• Build the Data Foundation: Create the datasets and pipelines your models need together with our engineer and the Data Engineering the first months this is a big part of the role.
• Shape Our ML Stack: Decide with the team how and where models run and set the practices for machine learning at Aroundhome.

• Solid foundation in experiment design and causal inference ideally in a marketplace where test and control groups affect each other.
• Hands-on experience with classical machine learning (e.g. gradient-boosted trees) probability calibration and offline vs online evaluation.
• A product mindset: you define success in homeowner and partner outcomes challenge assumptions with evidence and add complexity only where it earns its place.
