Machine Learning Engineer

Location: Remote (United States or Canada)

Employment Type: Full-time

Salary: $175,000–$220,000 per year

Hiring: 3 Open Positions

About The Role

We are seeking an experienced Machine Learning Engineer to design and build production-grade machine learning systems that power real-time fraud detection. This role goes beyond model development—you'll own end-to-end ML solutions, from data pipelines and feature engineering to model deployment, monitoring, and backend infrastructure.

If you're passionate about building scalable ML systems and solving complex fraud detection challenges, we'd love to hear from you.

Key Responsibilities

• Build and optimize data pipelines and backend services to process device and behavioral data in real time.
• Develop, deploy, and maintain machine learning models for fraud detection in production.
• Design and implement scalable feature pipelines from raw data.
• Collaborate with backend and platform engineering teams to integrate ML models into production systems.
• Monitor model performance, detect drift, and continuously improve model accuracy.
• Ensure high standards of security, privacy, reliability, and compliance.
• Follow engineering best practices for testing, documentation, and observability.
• Contribute to scalable backend services using Go and Python.
  
  

Required Qualifications

• Bachelor's or Master's degree in Computer Science, Engineering, or a related field.
• 5–8 years of software engineering experience with strong backend development and applied machine learning.
• Experience building and deploying end-to-end ML systems, including:
• Feature engineering pipelines
• Model deployment
• Monitoring and drift detection
• Continuous model improvement
