Data Engineer 

Job Description:

You’ll be managing data pipelines for companies that deal with large volumes of data. That means making sure that your data is being efficiently collected and retrieved from its source when needed, cleaned and preprocessed.

Requirements:

你将要使用的技术包括 Apache Spark、Hadoop、Hive & Kafka。SQL 的夯实基础也很重要的。

Regular Work：

→ “How do I build a pipeline that can handle 10000 requests per minute?”

→ “How can I clean this dataset without loading it all in RAM?”

Data Analyst

Job Description:

Your job will be to translate data into actionable business insights. You’ll often be the go-between for technical teams and business strategy, sales or marketing teams. Datavisualization is going to be a big part of your day-to-day.

Requirement:

你将使用的技术包括Python，SQL，Tableau 和 Excel。你还需要成为一个好的沟通者。

Regular Work:

→ “What’s driving our user growth numbers?”

→ “How can we explain to management that the recent increase in user fees is turning people away?”

Data Scientist

Job Description:

Your job will be to clean and explore datasets and make predictions that deliver business value. Your day-to-day will involve training and optimizing models, and often deploying them to production.

Requirements:

你将要使用的技术包括 Python, scikit-learn, Pandas, SQL，可能还有Flask，Spark 或者TensorFlow / PyTorch。有一些数据科学的职位纯粹是技术性的，但是大多数的都还是要求你有一些 business sense，这样你就不会最终花力气去解决毫无疑义的问题。

Regular Work:

→ “How many different user types do we really have?”

→ “Can we build a model to predict which products will sell to which users?”

Machine Learning Engineer 

Job Description:

Your job will be to build, optimize and deploy machine learning models to production. You’ll generally be treating machine learning models as APIs or components, which you’ll be plugging into a full-stack app or hardware of some kind, but you may also be called upon to design models yourself.

Requirements:

必要的技术包括Python, Javascript, scikit-learn，TensorFlow / PyTorch（and/or enterprise deep learning frameworks）和 SQL 或 MongoDB（通常用于app DB）。

Regular Work:

→ “How do I integrate this Keras model into our Javascript app?”

→ “How can I reduce the prediction time and prediction cost of our recommender system?”

Machine Learning Researcher

Job Description:

Your job will be to find new ways to solve challenging problems in data science and deep learning. You won’t be working with out-of-the-box solutions, but rather will be making your own.

Requirements:

你将要使用的技术包括Python，TensorFlow / PyTorch（和/或企业深度学习框架）和SQL。

Regular Work:

→ “How do I improve the accuracy of our model to something closer to the state of the art?”

→ “Would a custom optimizer help decrease training time?”
