What you’ll be doing 

As the Senior Data Scientist at Alloy, you'll:

  • Take ownership of our modeling efforts and how modeling happens at Alloy, including how we build, train, deploy and monitor models that help us distinguish 'good' applications from fraud
  • Ensure that live production models are served with high uptime/reliability and extremely low latency (<150 ms)
  • Articulate a feature engineering strategy for extracting signal from varied inputs and partner with our data engineering team to build a reliable pipeline to generate, store and use new features in production.
  • Expand the range of outcomes that we model, expanding beyond basic two-category classification to more robust models that identify particular fraud modalities
  • Deploy time-series models that score streams of transaction data and integrate with our onboarding models to provide a real-time view of risk
  • Hire junior data scientists and build out the data science vertical inside the data team

On a given day, this work might entail:

  • Analyzing closure data to improve the performance of a fraud model
  • Applying ML interpretability techniques to help explain and present the most salient features to a particular prediction made by a fraud model 
  • Working with our data engineering team to propose upstream changes in how cleaned training data is made available for modeling 
  • Working with our product team to update the roadmap for the future and vision of our custom modeling product and prioritize what we'll ship in the next quarter
  • Working with our customer analysis team to add more ML insights to our replicable client analyses
Who we’re looking for

Reporting to the Head of Data Science, the Senior Data Scientist will likely have:

  • A blend of ML/statistics experience and prior experience working on or with software teams to deploy ML models in production
  • Our production code is largely Python so familiarity with the Python data science stack is a must, but candidates whose primary experience is in R / Scala / Julia should not hesitate to apply
  • We particularly value candidates with strong pure math/physics backgrounds who are interested in applied problems
  • Prior experience in financial services (especially credit modeling) is a strong plus, but not a requirement
  • The seniority level for this position is mid-to-senior, and as such, successful applicants will have two+ years professional experience as a data scientist or similar role

Beyond the technical requirements for the role, we are looking for candidates who are curious, humble, quick learners, and strong communicators. Having strong organizational and prioritization skills will help you navigate the changes in company structure, product strategy and mix of job responsibilities that are inherent to a growing startup.

We are a lean team, so your impact will be felt immediately. If this all sounds like a good fit for you, why not join us?
