Join the Data Science team at BHN. This role is critical in ensuring our real-time fraud prevention systems, dynamic pricing engines, and risk models execute decisions within tight latency constraints. You will work closely with Data Scientists and ML Engineers to:

1. Take models (including XGBoost and neural networks) from experimentation to production, ensuring they are scalable, robust, and adhere to strict performance requirements. This is a highly technical role where your expertise in Java and distributed systems will directly impact the loss prevention.

2. Design, build, and maintain the high-performance, low-latency machine learning and data pipelines that underpin BHN's core business systems.

• Python-to-Java Translation (Core Function): Take analytic models and functions developed by the Data Science team in Python and accurately and efficiently translate (re-implement) them into robust Java code for use in high-performance production environments.
• Real-Time Pipeline Engineering: Design, implement, and maintain the high-availability, low-latency data and model decision pipeline, ensuring model scoring and risk evaluations are returned in approximately 10 milliseconds (ms).
• Backend Development: Develop and maintain scalable microservices, primarily using Java, to handle high-throughput model serving, API integration, and real-time risk management tools.
• Model Productionization: Work directly with Data Scientists to effectively productionize, integrate, and tune machine learning models (e.g., XGBoost, neural networks).
• System Maintenance and Extension: Build, maintain, and extend technology systems that provide significant value to BHN's business, including fraud prevention systems and internal analytics tool suites.
• Process Implementation: Drive the implementation of tactical pricing initiatives and strategy changes, addressing complex backend process and technical requirements.
• Cloud Operations: Utilize expertise with Amazon Web Services (AWS) or similar cloud platforms to ensure systems are deployed, monitored, and scaled efficiently.
• Collaboration: Work closely with data scientists, ML engineers, and product managers to define technical requirements and provide inputs to the overall systems roadmap.

• Education: Bachelor’s degree in Computer Science, Software Engineering, Mathematics, Physics, or a related analytical field.
• Experience: +2 years of experience developing and maintaining high-performance backend systems or real-time data/ML infrastructure in an engineering role.
• Core Languages: Strong, demonstrable proficiency in Java is essential for high-throughput, low-latency service development.
• Secondary Languages: Proficiency in Python for understanding, debugging, and translating ML code and data science prototypes.
• ML Comfort: Comfort with the structure and deployment of machine learning models and statistical modeling techniques, including algorithms like XGBoost and neural networks.
• Systems Expertise: Experience building robust systems at scale on top of Amazon Web Services (AWS) or similar cloud services.
• Problem Solving: Expert ability to break down and clearly define complex technical functions and develop scalable solutions.
• Communication: Excellent written and verbal communication skills for collaborating across engineering, data science, and product teams.
