About The Role As a Machine Learning Engineer, you’ll do more than build models - you’ll design the systems that make fraud detection possible. You’ll work across modeling, data pipelines, and backend systems (Go) to ensure ML models run reliably, efficiently, and at scale.

Build and optimize data pipelines and backend services to process device and behavioral data in real time.
Develop and deploy ML models for fraud detection, ensuring they run reliably and efficiently in production.
Turn raw data into production-ready features that feed our fraud detection systems.
Collaborate with platform and backend engineers to integrate models seamlessly.
Maintain high standards of security, privacy, and compliance.
Champion best practices in testing, documentation, and observability.
What You Bring
5+ years in software engineering, with strong backend experience (Go or Python).
Hands‑on experience with applied ML using large datasets (PyTorch, Scikit-learn, etc.).
Strong SQL skills and familiarity with relational and non‑relational databases.
Experience with end‑to‑end ML systems: feature pipelines, model deployment, monitoring, and iteration.
Excellent communication skills in English, both written and verbal.
Bachelor's or Master's in Computer Science, Engineering, or a related discipline.
Bonus Points
Domain knowledge in fraud, risk, or cybersecurity.
Familiarity with CI/CD, Docker, Kubernetes and the modern devops framework.
Understanding of modern browser APIs and high‑entropy data collection techniques.
Familiarity with leveraging frontier LLMs for automation.
Benefits we offer:
Generous compensation in cash and equity
Early exercise for all options, including pre‑vested

Flexible paid time off and Year‑end break
Health insurance, dental, and vision coverage for employees and dependents - US and Canada specific
