Data at Brex

The Data organization develops infrastructure, statistical models, and products using financial data. Our Data Scientists and Engineers work together to make data—and insights derived from data—a core asset across the company. Our work is ingrained in Brex’s decision-making process, in the efficiency of our operations, in our risk management policies, and in the second-to-none experience we provide to our consumers. 

What you’ll do

As an MLE, you collaborate with other platform and infra teams, build systems and tools to support Brex-wide ML efforts and initiatives. These tools enable data scientists to improve the core data quality at Brex, to iterate faster in the model development cycle including model training, online productionization and performance monitoring, essentially to achieve their optimal performance. 

Responsibilities

• Design and build user-friendly and ML guided tools upon which data scientists can easily test and deploy models to production.
• Apply your expertise in quantitative analysis and software engineering to build scalable and robust real-time ML models. 
• Work closely with data scientists to adopt the most recent ML technologies and ensure the highest engineering quality. 
• Collaborate with cross-functional teams to unravel complex problems by clearly formulating the problem statement, understanding technical requirements, and presenting findings at all levels. 
• Maintain a strong data driven culture within the company by interacting with diverse internal functions.

Requirements

• 3+ years in a Data Science / ML Engineering/ Software Engineering role
• Experience in software abstraction, scalable data application architecture for improving Data Scientist’s efficiency.
• Experience in the machine learning model development cycles, including model productionization and management. 
• Strong interpersonal and communication skills and having worked with different business functions.
• Experience with data pipelines and data warehousing, such as Airflow and Snowflake or equivalent tools and frameworks.
• Experience working with SQL or NoSQL databases 
• Experience working with one or more backend programming languages (C++, Java, Kotlin, Python)

Bonus points

• A MS or Ph.D. degree in a quantitative field (e.g. stats, physics, computer science)
• Experience contributing to machine learning platforms for building data pipelines and models
• Understands various tradeoffs in machine learning deployment such as computation optimization, performance requirements, latency and data quality assurance.
• Experience in deploying/managing/interacting with microservices, event-streaming pipeline and data intensive applications.
• Production experience with either Graphical Model, or Neural Networks or Tensorflow.
