Bad actors, small signals

Fake recruiter accounts post listings that ask candidates for a registration fee, and by the time a human reviews the report, forty people have already applied. You will build the model that catches them sooner.

Two months of work

Week one is a guided tour of the abuse data with the trust and safety team. After that you engineer features from posting behaviour, account age, text similarity to known scam listings and payment keyword patterns, then train an anomaly detector alongside a supervised classifier on the labelled reports we already hold. Class imbalance here is severe, so precision recall curves and a threshold you can defend to a non technical reviewer matter far more than an accuracy figure. Your final week goes into a writeup of what the model still misses and why.

What you need

A final year student or recent graduate, comfortable in Python and pandas, with scikit-learn picked up from coursework or personal projects. No professional experience expected. The role runs fully remote within India for two months, with a daily standup and one deep review session each week. If you enjoy reading a dataset until it confesses, this will suit you.

Responsibilities

  • Audit real abuse reports with the trust and safety team during your first week
  • Engineer features from posting behaviour, account age and payment keyword patterns
  • Measure text similarity between new listings and a corpus of confirmed scam posts
  • Train an unsupervised anomaly detector alongside a supervised classifier
  • Tune the decision threshold using precision recall curves and defend it to a non technical reviewer
  • Document what the model still misses in a final handover writeup

Requirements

  • Final year student or recent graduate with no prior professional experience
  • Python, pandas and scikit-learn from coursework or personal projects
  • Understanding of why accuracy is misleading on imbalanced data
  • Available for two months, working fully remotely within India

Skills

Benefits

  • Paid monthly stipend for a short two month commitment
