About the role

The Head of Fraud will be in charge of seeding the risk function at Común, ensuring that we can accomplish our mission of providing financial access to immigrants while removing bad actors from our systems. This is a highly collaborative role that will interface with most company functions and touch our entire product suite, and is a key dependency to enable a great customer experience.

We are looking for someone with a strong analytical background who can get their hands dirty with data analysis and modeling and can succeed with a lean team. This role will own all of KYC, ongoing monitoring, fraud exposure, and anti-money laundering, and report directly to the founders.

What you’ll do:

Reporting directly to the founders you'll collaborate with Growth, Compliance, Operations, Product, Engineering, and our partner banks to iterate on a KYC policy that is inclusive, compliant, and continuously filtering out bad actors.
Maintain a strong monitoring practice across both automated alerts and BPO manual reviews, to enable sharp decision-making and provide continuous feedback to our automated models.
You will own fraud exposure, and will work on data models to continuously eradicate fraud losses across our features: check deposits, ACH transfers, debit card disputes, and peer transfer chargebacks.
Own and continuously optimize our real-time transaction authorization model for remittances and P2P.
Work with Compliance and Data to maintain tight anti-money laundering controls across any new addition to our feature set.
Own a holistic customer risk model that draws from behaviors across our entire feature set to determine what experience we can show to each user.
Improve and maintain our fraud stack, ensuring we have the best tools and vendors to make data-driven decisions.
Collaborate with Product and Engineering to establish robust controls across our product suite and establish the appropriate testing frameworks to ensure we achieve the intended outcomes.

Hands-on experience with SQL, machine learning, regressions, and data modeling.
Experience building holistic customer risk models in other fintech products
Familiarity with money laundering patterns, behaviors, and mitigation strategies.
Familiarity with fraud, KYC, and risk vendors across orchestration, data, and decisioning needs.
A high degree of collaboration across many stakeholders at Común’s leadership level.
A customer-obsession mindset that allows you to properly set tradeoffs between stricter controls and providing a delightful customer experience.
