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

7. 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

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

10. What can you do?
Build a team instead.

14. • 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

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

16. Data Science Team Structures
CentralizedEmbeddedHub & Spoke

17. 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.

18. 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.

19. 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.

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

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

23. Data Science Software Engineering

24. 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

27. • 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

to anyone with aptitude and ambition.
