Our mission

In 2019, 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.

Sendwave's mission is to change that by making sending money anywhere in the world as easy and affordable as sending a text. Since 2014, our app has allowed users in the US, the UK, Spain, Ireland, France, Italy and Canada to send money instantly to mobile money wallets in Kenya, Uganda, Tanzania, Ghana, Nigeria, Senegal (and soon Bangladesh) saving our users over 70% relative to Western Union and MoneyGram.

We're looking to rapidly expand throughout the globe in the next year. 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 ML skills to develop accurate, data-driven defenses to fight fraud.

On any given day, you may:

  • Implement new modeling to reduce our overall risk of individual and coordinated fraud attacks.
  • Develop heuristics to quickly fight fraud.
  • Create tooling and “explainer” models to help our risk-representatives make sense of a model result.
  • Evaluate and integrate a new data sources for our fraud detection algorithms in real-time and pipe the results into our analytical environment.
  • Implement policies around our model code to prevent too many users from being negatively impacted
  • Develop strategies to detect previously unseen patterns that may indicate a new fraud attack.
  • 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 APIs into our risk defenses.
  • 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.
