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 https://www.worldbank.org/en/topic/financialinclusion/overview 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. Most lending systems spend a lot to guess who will repay, and yet so many who are creditworthy still can’t get a loan.
We built an alternative called Credit. Since December 2024, it has issued over one million https://credit.cash/analytics unsecured 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 https://writing.divine.inc/seed-round/ from Paradigm and Nascent, we're scaling a system that has already reached more than 900,000 unique borrowers. Help us take it to the next level.
ABOUT THE ROLE
We seek a statistical machine learning researcher to build and improve the adaptive decision systems behind Credit, our leading unsecured 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.
This role is based in San Francisco, California. We work in a hybrid model, with the team in office 3 days per week.
STACK
- Python
- TypeScript
- Bayesian/probabilistic modeling (PyMC, Stan, NumPyro, or similar)
- Bandit and RL frameworks
- SQL
- Grafana/Prometheus/Metabase
KEY RESPONSIBILITIES
- 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
REQUIREMENTS
- 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
- Comfortable with ambiguity and biased toward action; thrives with minimal oversight and brings strong problem-solving skills and sharp attention to detail
NICE TO HAVE
- 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
