JOB DESCRIPTION

Our mission

In 2017, immigrants worldwide sent over $600 billion home to family and friends, dwarfing foreign governmental aid. In the age of cheap, quick transfers through services like Paypal and Venmo, these people are trekking to stores to pay fees averaging over 7% for transfers that typically take 24 hours or more. 
Wave’s mission is to change that by making sending money anywhere in the world easy and affordable. Since 2014, our app has allowed Africans in the US, the UK, and Canada to send money instantly to mobile money wallets in Kenya, Uganda, & Tanzania, saving our users over 70% relative to Western Union and MoneyGram. 
As we serve more and more customers, Wave will need to ensure that we’re able to identify and prevent fraud. We’re building a world class risk team comprised of engineers, data scientists, and operations team members to ensure that we’re able to fight fraud and provide our customers with the best user experience possible.
We’ve gotten pretty good at fighting fraud but we are looking to rapidly expand throughout Africa in the next year, including Nigeria. That’s where you come in…

How you’ll help us achieve it

Our Risk Engineers build and support everything that helps lower our risk exposure. This includes integration of vendor tools, training new fraud/anomaly detection algorithms, supporting our risk operations teams and improving our monitoring capabilities. You’ll leverage your technical skills to build out new tooling for our Risk Representatives, integrate new data sources, build feature engineering pipelines and help evaluate new models. 
On any given day, you may:
  • Evaluate and integrate a new data sources for our fraud detection algorithm in real-time and pipe the results into our analytical environment.
  • Update a defense heuristic when we discover a new fraud ring/pattern.
  • Automate the training and deployment of updated models.
  • Develop a new anomaly detection algorithm, helping us spot strange behavior before a chargeback occurs.
  • Create real-time and batch ETL jobs for our analytical tools.
  • Integrate vendor data and models into our risk defenses.
  • Enhance our Risk Representatives’ tooling to better capture their judgements in order to improve our models and risk flags.
  • Help build experiments to evaluate new models, third-party data sources and tooling.
  • Modifying UIs that serve alerts to our Risk Representatives to help them work fraud alerts more efficiently.
We’re building out a best-in-class Risk infrastructure that can enable us to grow and we’re hoping to find an engineer that’s excited to solve data-driven problems in an adversarial environment.
