Role Summary – Machine Learning Engineer
As a Machine Learning Engineer at PayPal, you’ll design, implement, and maintain ML models that solve critical business problems such as fraud detection, risk scoring, customer personalization, and automated support. You will translate research prototypes into robust, monitored services; build scalable training and serving pipelines; and ensure model fairness and compliance with regulatory standards. This role expects you to be comfortable with data engineering tasks, model evaluation, and cross-functional collaboration – key skills for those seeking Machine Learning Engineer Jobs for Freshers who plan to grow quickly.
Requirements
- Bachelor’s degree in Computer Science, Data Science, Statistics, or related discipline – Master’s preferred but not mandatory.
- 2+ years of professional experience in ML engineering or strong demonstrable projects for freshers applying under Machine Learning Engineer Jobs for Freshers.
- Proficient in Python and familiar with libraries like TensorFlow, PyTorch, scikit-learn, and Hugging Face Transformers.
- Experience with SQL and working knowledge of data warehouses, big-data tools, or Spark is a plus.
- Comfort with cloud platforms (AWS or GCP) and MLOps tools for CI/CD, monitoring, and model deployment.
- Strong problem-solving skills, clear communication, and the ability to explain technical concepts to non-technical stakeholders.
- Understanding of model evaluation metrics, bias/fairness considerations, and data privacy principles.
Key Responsibilities
- Design and implement ML models and pipelines to address business problems, from data ingestion to serving.
- Collaborate with data scientists to productionize prototypes through robust engineering practices.
- Preprocess and analyze large-scale structured and unstructured datasets; develop feature engineering solutions.
- Build automated training and evaluation workflows; implement model monitoring and alerting for drift or performance degradation.
- Optimize inference latency and throughput for production services; contribute to cost-efficient model serving strategies.
- Participate in code reviews, design discussions, and knowledge-sharing sessions; document model decisions and assumptions clearly.
- Work on LLM-based solutions: prompt engineering, fine-tuning, safety checks, and integrating generative models into product flows.
A Day in the Life
Your morning might begin with a quick stand-up where the team reviews model metrics and deployment statuses. After that, you could be running experiments to improve a fraud model’s recall, reviewing feature importance charts, or debugging a flaky data pipeline. Midday could include a design review with product and security teams to ensure a proposed LLM feature meets compliance needs. In the afternoon you may implement model monitoring dashboards, respond to alerts, and prepare a short summary for stakeholders. Great ML engineers balance coding with communication – and every week you’ll prioritize improvements that make the system safer and more reliable.
Compensation & Benefits
- Competitive base salary and performance-based bonuses aligned with market standards.
- Employee equity or stock option plans for eligible roles.
- Comprehensive health insurance, wellness programs, and employee assistance resources.
- Generous learning & development allowance, mentoring programs, and internal mobility options.
- Flexible hybrid working model and policies to support work-life balance.
