Build, deploy, and iterate on production machine learning models for ranking, personalization, and marketplace optimization. Own the end-to-end lifecycle from problem framing and feature engineering to A/B testing and production monitoring.
The Opportunity
Apartment List is looking for a Lead Data Scientist to build, deploy, and improve machine learning models that power our two-sided rental marketplace.
In this role, you’ll work on meaningful data science problems across demand- and supply-side modeling — from renter acquisition and intent signals to ranking, personalization, and marketplace optimization. You’ll take ownership of projects end-to-end, from problem framing through production launch and measurement, and collaborate closely with Product, Engineering, and Analytics along the way.
Our Data Science team has a strong foundation. Over the last several years, we’ve delivered 40%+ incremental revenue growth through rigorously A/B tested machine learning models — and there’s still a tremendous amount of opportunity ahead. This is a role for someone who is ready to take on complex, well-scoped projects independently and grow into increasingly ambiguous, high-leverage work.
Here’s what you’ll do as part of the team
- Translate customer, marketplace, and business problems into clear ML objectives, features, models, and measurement plans.
- Build, deploy, and iterate on production machine learning models across ranking, personalization, renter intent, demand-side acquisition, and supply-side optimization.
- Own projects end-to-end — from feature engineering and model development through A/B experimentation, launch, and monitoring.
- Apply a strong statistical mindset to model development, evaluation, causal inference, and tradeoff analysis.
- Partner with Product, Engineering, and Analytics to align on success metrics, deployment plans, and downstream impact.
- Communicate technical findings and model tradeoffs clearly to both technical and non-technical stakeholders.
- Leverage AI tools to improve your productivity across coding, analysis, documentation, and workflow automation.
Here are the skills and experience you’ll need to be successful
Must-haves
- 4+ years of industry experience developing and deploying machine learning models in production, end-to-end.
- A degree in Data Science, Computer Science, Computer Engineering, Mathematics, Statistics, Economics, Physics, or a related quantitative field.
- Deep proficiency in Python and SQL, with comfort across the full model development lifecycle.
- Familiarity with standard ML libraries and frameworks such as scikit-learn, XGBoost, TensorFlow, PyTorch, or similar.
- Experience working with cloud platforms (GCP preferred but not required).
- Strong grounding in statistical learning, experimental design, and model evaluation.
- Ability to work through feature engineering, feature selection, hyperparameter tuning, and model optimization independently.
- Comfort communicating and collaborating with cross-functional partners across Product, Engineering, and Analytics.
Nice-to-haves
- Experience in a two-sided marketplace or multi-stakeholder environment.
- Background in recommendation systems, ranking, personalization, or search.
- Familiarity with MLOps practices, model monitoring, Airflow, dbt, or similar infrastructure.
- Experience with performance marketing models, paid acquisition, or supply-side optimization.
- A master’s degree or higher in a relevant quantitative field.
What’s in it for you
- Impact: Work on ML systems that directly shape the renter experience, property partner outcomes, and company performance.
- Ownership: Build and own models end-to-end, from ambiguous opportunity through production launch and iteration.
- Exceptional colleagues: Our hiring bar is high, and your teammates are talented, motivated, collaborative, and intellectually curious.
- Influence: Have a strong voice within R&D and across the business, helping shape product, marketplace, and company strategy through data science.
- A critical function: Help build and scale one of the most important technical capabilities at Apartment List.
- Culture: Work in a virtual-first environment that allows you to work from anywhere in the U.S.
