Decision Scientist vs. Research Engineer

A Comprehensive Comparison of Decision Scientist and Research Engineer Roles

Table of contents

As the world becomes more data-driven, the demand for professionals in the AI/ML and Big Data space continues to grow. Two roles that have gained popularity in recent years are Decision Scientist and Research Engineer. While both roles deal with data and analytics, they have distinct differences in terms of their responsibilities, required skills, educational backgrounds, tools and software used, common industries, outlooks, and practical tips for getting started in these careers. In this article, we will explore these differences in detail.

Definitions

A Decision Scientist is a professional who uses data, Statistics, and Machine Learning algorithms to solve complex business problems. They work closely with business stakeholders to identify key performance indicators, develop hypotheses, and use data to validate or refute these hypotheses. Decision Scientists are responsible for developing models that can predict future outcomes and provide recommendations to business leaders. They are also responsible for explaining complex models and insights to non-technical stakeholders.

A Research Engineer, on the other hand, is a professional who designs, develops, and implements algorithms and systems for processing and analyzing large datasets. They work on cutting-edge research projects that involve developing new Machine Learning algorithms or improving existing ones. Research Engineers are responsible for conducting experiments, analyzing data, and publishing research papers in academic or industry conferences. They are also responsible for developing software tools and libraries that can be used by other researchers or engineers.

Responsibilities

The responsibilities of a Decision Scientist and a Research Engineer differ significantly. A Decision Scientist is responsible for:

• Collaborating with business stakeholders to identify key performance indicators and develop hypotheses.
• Collecting, cleaning, and analyzing data to validate or refute hypotheses.
• Developing predictive models and providing recommendations to business leaders.
• Explaining complex models and insights to non-technical stakeholders.

A Research Engineer, on the other hand, is responsible for:

• Designing and developing algorithms and systems for processing and analyzing large datasets.
• Conducting experiments to validate or refute hypotheses.
• Analyzing data and publishing research papers in academic or industry conferences.
• Developing software tools and libraries that can be used by other researchers or engineers.

Required Skills

The required skills for a Decision Scientist and a Research Engineer also differ significantly. A Decision Scientist should have:

• Strong analytical skills and the ability to work with large datasets.

• Business acumen and the ability to understand business problems and develop solutions.

A Research Engineer, on the other hand, should have:

• Strong programming skills and proficiency in languages such as Python, Java, or C++.
• Proficiency in machine learning algorithms and Deep Learning frameworks such as TensorFlow or PyTorch.
• Strong mathematical skills and the ability to develop new algorithms.
• Knowledge of software Engineering principles and the ability to develop scalable and efficient systems.

Educational Backgrounds

The educational backgrounds of a Decision Scientist and a Research Engineer also differ. A Decision Scientist should have:

• A bachelor's or master's degree in a quantitative field such as statistics, Mathematics, or Computer Science.
• Knowledge of business principles and experience working in a business environment.

A Research Engineer, on the other hand, should have:

• A master's or Ph.D. degree in Computer Science, electrical engineering, or a related field.
• Strong research experience and a track record of publishing research papers in academic or industry conferences.

Tools and Software Used

The tools and software used by a Decision Scientist and a Research Engineer also differ. A Decision Scientist should be proficient in:

• Statistical analysis tools such as R or SAS.
• Machine learning libraries such as Scikit-learn or XGBoost.
• Business Intelligence tools such as Tableau or Power BI.

A Research Engineer, on the other hand, should be proficient in:

• Programming languages such as Python, Java, or C++.
• Machine learning frameworks such as TensorFlow or PyTorch.
• Distributed computing frameworks such as Hadoop or Spark.

Common Industries

The industries in which a Decision Scientist and a Research Engineer work also differ. A Decision Scientist can work in:

• Finance and Banking.
• Healthcare.
• Retail and E-commerce.
• Marketing and advertising.

A Research Engineer, on the other hand, can work in:

• Technology companies.
• Research institutions.
• Government agencies.
