Many companies try to find
all of these skills in a single person.

Which leads to job requirements
like this… • MSc/PhD in Computer Science, Electrical Engineering, Math or Statistics • At least 5 years of experience in solving real-world practical problems using Machine Learning • At least 5 years of experience on mining and modeling large-scale data (hundreds of terabytes) • Extensive in-depth knowledge of Data Mining, Machine Learning, Algorithms • Knowledge of at least one high-level programming language (C++, Java) • Knowledge of at least one scripting language (Perl, Python, Ruby) • Knowledge of SQL and experience with large relational databases • Knowledge of at least one ML toolset (R, Weka, KNIME, Octave, Mahout, scikit-learn) • Strong ability to formalize and provide practical solutions to research problems • Strong communication skills and ability to work independently to get an idea from inception to implementation. • Knowledge of the state of the art in at least one of Bayesian Optimization, Recommendation Systems, Social Network Analysis, Information Retrieval • At least 5 years of experience with storing, sampling, querying large-scale data (hundreds of terabytes) and experimentation frameworks • At least 5 years of experience with Hadoop, Spark, Mahout or Giraph

Data Science Unicorn

These people do exist, but
they are often already well-compensated, and only want to work on interesting problems.

What can you do? Build
a team instead.

• Compose teams of individuals
who have overlapping skill-sets and deep expertise in one area (machine learning, statistics, engineering, business, etc.) • The overlap allows them to speak the same language and work collaboratively on solving problems

How do I structure my
data science team within my organization?

Data Science Team Structures CentralizedEmbeddedHub
& Spoke

Centralized Data Scientists sit on
a team that acts as internal consultants, fielding and answering questions from multiple teams within the organization, defining tools for the organization, and acting as highly powered consultants.

Embedded • Data Scientists are
almost wholly embedded within one particular team and focus on solving problems for that team. • Teams are assigned to one particular product or function within the company and define and answer questions for that product or function.

Hub & Spoke • The
data science team sits together physically and works collaboratively to solve problems. • However, each data scientist (or a combination of them) gets deployed to work on problems within the organization. • Tends to apply to companies who have a lot of users.

How do I get my
data scientists to work with engineering?

& prototyping production Software Engineering Java/C++ RoR/Javascript

Data Science Software Engineering Python
R Java/C++ RoR/Javascript modeling & prototyping production

Data scientists learn to write
prototypes in production languages Engineers learn the basics of data science so they can understand how the models work Goal is to have both teams speak the same language and engender trust through communication

• Don’t look for unicorns,
build collaborative teams of T-shaped people • Pay attention to how your data science team is structured within your organization • Get your data science and engineering teams to speak the same language, allowing them to build trust and work collaboratively Summary

We believe an opportunity belongs
to anyone with aptitude and ambition.
