About the position

The Machine Learning team is a relatively new team whose initial goal is to productize an Automated Machine Learning (AutoML) platform. This team works closely with the Backend Workflow team within the Core Services group in order to deliver ML pipelines as a service for all customers. Additional ML solutions already in our roadmap include Text Analysis, Causal Analysis/Discovery, Explainable AI (XAI), Uplift modeling, and Exploratory Data Analysis (EDA).

Productizing our ML products as a scalable cloud service requires diverse knowledge and experience not only in data science, but also software engineering. Areas such as container platform Java APIs (AWS ECS), AWS cloud API programming, Python ML libraries, SQL query processing for large data, Pandas dataframe processing for feature engineering, and AWS infrastructure management using Terraform are all topics you will be directly involved with over the course of your work in the ML team at Treasure Data.

This position is ideal for those with not only Data Science and Machine Learning skills, but also conventional cloud engineering skills for developing, deploying, and operating these critical ML products. This ML engineer position will expect candidates to understand machine learning algorithms, have experience in data analysis, and desire to grow as a software engineering in cloud computing environments.

Success in this role requires a passion for developing and productizing ML products with strong interests and knowledge in data science along with strong experience in software engineering.

You do this by collaborating with others to achieve our shared goals together in a self-organized team; pursuing autonomy with ownership, while increasing trust and sustainability to evolve continuously together. You would be able to effectively communicate ideas, software system designs, implementations, and decisions in a clear and concise manner to make others understandable.
