About the Role
Traditional credit was built for people who already have money. Requirements for credit history, collateral, and costly underwriting create insurmountable barriers for those who need capital most. Over 1.4 billion people lack access to credit. A vendor in Lagos earns cash daily but can't prove a steady income. A Colombian nurse with years of perfect informal repayments remains invisible to banks.
We built an alternative called Credit. Since December 2024, it has issued hundreds of thousands of undercollateralized loans using stablecoins. People from around the world have used these loans to pay for things like groceries, medicine, and transportation. Backed by $6.6 million from Paradigm and Nascent, we're scaling a system that has already reached half a million unique borrowers. Help us take it to the next level.
We seek a talented individual to build and improve the adaptive decision systems behind Credit, our leading undercollateralized lending system. You'll design models that learn borrower behavior over time and make optimal lending decisions under uncertainty, balancing exploration with exploitation across hundreds of thousands of users worldwide. You'll also develop the offline evaluation and monitoring infrastructure to safely validate these systems before deployment.
Python
TypeScript
Bayesian/probabilistic modeling (PyMC, Stan, NumPyro, or similar)
Bandit and RL frameworks
SQL
Grafana/Prometheus
Design, maintain, and optimize adaptive credit policies using methods like Thompson Sampling, contextual bandits, and Bayesian models
Formulate lending decisions as sequential decision problems under uncertainty (e.g., progressive trust-building, dynamic credit limits, risk-aware exploration)
Build offline evaluation frameworks to safely test new policies before going live
Model borrower behavior with limited, non-stationary data across diverse emerging-market populations
Develop tools, alerts, and analytics to monitor policy performance and detect distribution shifts
Collaborate with engineering to implement decision systems in production
Graduate degree in a quantitative field such as mathematics, physics, or computer science.
Very strong foundations in probabilistic modeling and Bayesian inference
Experience applying bandit algorithms to real-world decision problems in production (credit, pricing, recommendations, resource allocation, or similar)
Ability to make and defend pragmatic tradeoffs (e.g., heuristic > learned policy, simple bandit > deep RL) based on empirical evidence and to communicate them well verbally and in internal research write-ups.
Experience in Python, Typescript, SQL, and programming for data analysis
Exceptional problem-solving skills and attention to detail
Experience in traditional credit, lending, fintech, or insurance, especially in emerging markets or data-scarce environments
Published work or open-source contributions in bandits, Bayesian ML, or sequential decision-making
Experience with DeFi protocols, especially lending or credit systems
Familiarity with blockchain data indexing and onchain analytics
