4. Java

Java is a widely-known programming language that was invented in 1995 and is owned by Oracle. It is a server-side language that was created to let app developers "write once, run anywhere". It is easy and simple to learn and use and is powerful, fast, and secure. This object-oriented programming language lets the code be reused that automatically lowers the development cost. Java is specially used for android apps, web and application servers, games, database connections, etc. This programming language is closely related to C++ making it easier for the users to switch between the two.

Here's how senior data scientists use java:

Developed MapReduce jobs in java for data cleaning and preprocessing.
Designed and developed a distributed analytics processing engine for geo-spatial data processing (Java).

5. Data Analysis

Here's how senior data scientists use data analysis:

Utilized data analysis and machine learning techniques for Fraud detection, marketing and optimization.
Facilitated the data analysis and provide design assistance for predictive / statistical modeling techniques.

6. Hadoop

Hadoop is an open-source software and procedures framework that is free for anyone to use on the internet. Hadoop aids in big data operations. It allows massive data storage, applications to be run on commodity hardware, and can easily manage to run various tasks occurring at the same time.

Here's how senior data scientists use hadoop:

Understand the business requirement and actively involved in evaluating the Hadoop system.
Led data scientist and engineer team to develop and deploy a cross sectional factor model in Hadoop environment.

7. Predictive Models

In an effort to understand what could happen in the future, predictive models provide the statistical analytics to estimate the possibilities. With predictive modelling, relevant data is collected for the subject that requires forecasting, analysed and modelled to create different outcomes. The importance of this is to provide a basis for decision making that will foster a desired outcome for a business or government.

Here's how senior data scientists use predictive models:

Identified data trends, and used training, test & validation data for predictive models (ARIMA models).
Audited and validated the customer selection results - segmented based on behavior, predictive models, and other criteria.

8. TensorFlow

Here's how senior data scientists use tensorflow:

Claim Damage Estimate: use deep learning tool TensorFlow for image classification on damaged cars.
Support stack for GPUs, used for TensorFlow models.

9. Machine Learning Techniques

Here's how senior data scientists use machine learning techniques:

Utilized machine learning techniques for predictions & forecasting based on the Sales training data.
Predicted and monitored bearing temperature of the main gearbox at a WTG by employing the afore-mentioned machine learning techniques.

10. Scala

Scala is a modern programming language with multiple paradigms with which common programming models and patterns can be concisely, elegantly, and reliably expressed. Scala was created by Martin Odersky and published the first version in 2003. It combines functional and object-oriented programming in a concise high-level language. Many of Scala's design decisions are aimed at addressing criticism of Java. It interoperates seamlessly with both Java and Javascript. It is strongly seen as a static type language and does not have a primitive data concept.

Here's how senior data scientists use scala:

Use PostgreSQL, Scala and R for various data analytics tasks.
Spark, Spark Streaming, Scala, R, Cassandra, Oozie, Cloudera.

11. Statistical Analysis

Here's how senior data scientists use statistical analysis:

Developed classification and regression models to perform regression, classification and clustering statistical analysis.
Applied advanced machine learning to perform regression, classification and clustering statistical analysis.

12. Machine Learning Algorithms

Machine learning algorithms involve the engines of machine learning. It consists of the algorithms that turn a data set into a model.

Here's how senior data scientists use machine learning algorithms:

Sound understanding of service business and implementation of Machine Learning algorithms, Data modeling techniques in the service domain.
Identified and targeted welfare high-risk groups with Machine learning algorithms.

13. AWS

Here's how senior data scientists use aws:

Diagnosed denial of service attacks and improved security using AWS security groups and network ACLs.
Worked with AWS to implement the client-side encryption as Dynamo DB does not support at rest encryption at this time.

14. Healthcare

Healthcare is the maintenance or improvement of a person's health by the diagnosis and treatment of a person's injury, illness, or any other disease. Healthcare is a basic necessity of human life and is the responsibility of the country's government to ensure that each person gets healthcare. Providing healthcare is the job of certified health professionals that includes doctors, surgeons, nurses, and other physicians. Pharmaceutical companies, hospitals, dentistry, therapy, and health training all come under healthcare. Healthcare plays a vital role in the country's economy and its development.

Here's how senior data scientists use healthcare:

Developed probabilistic models of disease progression to predict future healthcare utilization and capitation revenue.
Developed a generic model for predicting repayment of debt owed in the healthcare, large commercial, and government sectors.

15. Natural Language Processing

Here's how senior data scientists use natural language processing:

Contributed in the implementation of the company's platform for Natural Language Processing.
Use natural language processing and topic clustering analysis with Latent Dirichlet Allocation and Non- negative Matrix Factorization.

What skills help Senior Data Scientists find jobs?

Tell us what job you are looking for, we’ll show you what skills employers want.

What skills stand out on senior data scientist resumes?

Yingfu (Frank) Li Ph.D.

Program Chair of Statistics and Associate Professor of Statistics, University of Houston - Clear Lake

Statistical computing and communication skills

What hard/technical skills are most important for senior data scientists?

Michael Gallaugher Ph.D.

Assistant Professor, Elected Director of The Classification Society, Baylor University

With the types of data being analyzed today, computational and coding skills are key. Anyone entering the statistics field, regardless of going into academia or industry, should be comfortable coding in at least one statistical computing language such as R, python, or more recently, Julia. In addition, and this is probably obvious, strong mathematical skills are also very important.

What soft skills should all senior data scientists possess?

Kazim Sekeroglu Ph.D.

Assistant Professor, Computer Science, Southeastern Louisiana University

Since data science is a very broad area, and it has application in almost any field, being able to communicate with people from different fields to understand the data, as well as the problem, is very crucial.

What senior data scientist skills would you recommend for someone trying to advance their career?

Neil Rothman Ph.D.

Professor and Program Coordinator, Stevenson University

Any gap year experience should be complementary to their degree program and career goals. If they lack a specific skill that is important in their field of choice, they should focus on that. Otherwise, any experience is useful knowledge, but an experience that provides a better perspective on why they are pursuing a particular career would be best. Most jobs require a multidisciplinary approach to problem-solving, but most degree programs don't necessarily provide this. Software development and data analysis will be crucial in almost any career, so that might be something to look at (e.g., Python, R, etc.).

What type of skills will young senior data scientists need?

Xingye Qiao Ph.D.

Associate Professor, Binghamton University

Computing skills are becoming increasingly important, as statistics embraces the data science revolution. Students need to be able to program (using R or Python or some other language), take the data from the web, reshape it, manipulate it to allow easier downstream analysis, and be able to communicate the finding professionally.

All these are, of course, on top of statistical thinking. Competitive student candidates should not only be an order-taker. They should ask hard questions and think about the data problem in the context of the environment that generates the said data. This is related to knowledge of the domains, human contexts, and all kinds of ethical considerations.
