What are some of the exciting challenges you will be working on? 

Safety & Trust AI Feature Development 

  • Collaborate with cross-functional teams to design, develop, and implement AI features to enhance user safety and trust. 
  • Leverage machine learning techniques to build predictive models for identifying potential abusive patterns in user behavior. 

Anomaly Detection 

  • Lead the design and implementation of anomaly detection systems to identify deviations from normal user behavior. 
  • Develop algorithms and models to recognize and mitigate potential abuse scenarios. 

Data Analysis 

  • Conduct in-depth analysis of large datasets to extract meaningful insights related to user behavior and safety trends. 
  • Work closely with Data Engineers to ensure data quality, integrity, and accessibility for analysis. 


  • Collaborate with cross-functional teams, including product managers, software engineers, and security experts, to integrate safety and trust features seamlessly into our products. 

Model Evaluation and Optimization 

  • Evaluate the performance of machine learning models regularly and implement improvements as needed. 
  • Optimize algorithms for scalability, efficiency, and accuracy in real-time anomaly detection scenarios. 

What does it take to work at LastPass? 

  • Background in Computer Science, Data Science, Statistics, or a related field. 
  • Proven experience in developing and deploying machine learning models, with a focus on anomaly detection. 
  • Proficiency in programming languages such as R, Python, and experience with relevant libraries and frameworks (e.g., TensorFlow, PyTorch). 
  • Familiarity with data/ML technologies (e.g., Spark, Hadoop, DataBricks, MLflow) and distributed computing. 
  • Strong understanding of statistical modeling, data mining, and machine learning algorithms. 
  • Excellent communication skills with the ability to explain complex technical concepts to non-technical stakeholders. 
  • Good problem-solving skills, team player, and can-do attitude. 
  • Ability to communicate comfortably with different stakeholder groups with different backgrounds and technical understanding within LastPass. 
  • Good written and verbal communication skills in English. 

It's great, but not required: 

  • Experience working on projects related to online safety, trust, or abuse prevention. 
  • Familiarity with tooling related to abuse detection (e.g., Azure Sentinel, DataDog, Crowdstrike or Splunk) 
  • Knowledge of privacy and ethical considerations in data science. 
  • Experience working with global teams.
