This is a modeling-forward role for someone who thrives on solving real-world problems using clean code, principled experimentation, and scalable ML infrastructure. Why This Opportunity? Build the Core Intelligence Behind Decision Systems Design models that retrieve and rank high-value entities under noisy, ambiguous conditions. Apply techniques from recommender systems, representation learning, and constrained optimization to drive measurable outcomes. Collaborate cross-functionally to translate product intuition and messy data into well-defined modeling problems. Technical Team, Product-Minded Culture Work with a team of applied scientists, engineers, and product leaders who bring deep experience in ML infrastructure and system design. Emphasis on upstream modeling — the work starts well before model selection and continues through post-deployment iteration. Contribute to an environment that values curiosity, rigor, and getting things done without excess process. Remote-First with Room to Grow U.S.-based remote role with flexibility and focus. Minimal bureaucracy, lean processes, and full autonomy to drive your work forward. Opportunities for advancement, technical ownership, and mentorship as the team scales. What the Role Involves Build and iterate on models for retrieval, ranking, and personalization using collaborative filtering, embeddings, and optimization-based approaches. Evaluate model quality through MAP, NDCG, View email address on click.appcast.io, and other offline metrics. Partner with engineers to deploy models into production and monitor their performance. Write clear, reproducible research and run offline experiments to support ongoing improvements. Help define and improve best practices for experimentation, testing, and code quality. What We’re Looking For 3+ years of experience in data science, ML engineering, or applied modeling roles. Experience with ranking or recommendation systems, ideally in production environments. Proficiency in Python and modern ML libraries such as PyTorch, TensorFlow, Scikit-learn, or XGBoost. Strong statistical intuition, hands-on coding skills, and an understanding of model evaluation. Comfortable working independently, taking ownership of end-to-end modeling tasks. Bonus: background in optimization, information retrieval, or experimentation infrastructure. Must be a U.S. Citizen or Green Card holder. This is a rare opportunity to work on technically rich problems with immediate real-world impact — in a fast-moving team that values clear thinking, clean modeling, and production-grade execution. If you're excited about building intelligent ranking systems from the ground up, we’d love to hear from you.
