The Role
We are looking for an Applied Scientist / Applied ML Engineer to design, build, and deploy machine learning models that power pricing, bidding, and decisioning on a cross-border payments platform. This role owns problems end to end, from formulation to production, and partners closely with Product and Backend Engineering.
Key Responsibilities
- End-to-End ML Ownership
- Own end-to-end ML solutions for pricing, bidding, and risk decisioning.
- Formulate model objectives from first principles, including loss functions, constraints, and metrics, and implement them as production-grade services.
- Experimentation & Iteration
- Design and run experiments, including A/B tests and offline evaluations, and iterate with clear success metrics.
- Production Monitoring
- Monitor models in production, investigate regressions, and continuously improve performance.

Requirements
Essential
- 3-7 years of experience as an ML Engineer, Applied Scientist, or Data Scientist in industry.
- Bachelor's or Master's in Computer Science, Machine Learning, Mathematics, Statistics,



or equivalent practical experience.
- Solid Python skills, including pandas, NumPy, and scikit-learn, plus at least one of PyTorch, TensorFlow.
- Strong ML fundamentals, including supervised and unsupervised learning, model evaluation, regularization, feature engineering, and statistics.
- Experience designing models from first principles and shipping them to production, in batch or real-time.
- Hands-on experience with data pipelines and ETL, such as Airflow or Spark, and strong SQL for feature engineering.
- Experience integrating ML into REST or gRPC APIs and microservice architectures.
- Ability to design and interpret experiments with statistical rigor.
- Strong problem-solving and communication skills, and the ability to work effectively in cross-functional and distributed teams.

Nice to Have
- Optimization, bandits, or decision-making under uncertainty, including dynamic pricing and bid optimization
