Finding data scientists for hire can be challenging for companies. Although data science has become a demanding skill in many industries, finding qualified data scientists for hire can be challenging. That's why we assist companies trying to hire data scientists independently.

Hiring data science developers can be a complex task if you don't come from a technical background. At UltraGenius, we offer highly skilled data scientists for hire who can be onboarded within 24 hours.

What are the Essential Skills to Look for While Hiring a Data Scientist?

If you are from a non-technical background, and are looking for more information about hiring top data scientists, here we mention the essential skills for a Data Scientist:

1. Strong command in Python

Python is the go-to coding language for data scientist roles. Developers often utilize this language in various steps of the data science processes, import SQL tables into codes easily with Python, and create datasets quickly sourced through Google. 

 

As a result, when hiring offshore data scientists it's wise to ensure they have a strong command of this coding language. So when choosing one, make sure they possess strong knowledge in Python, as this could make a big difference!



2. Understanding of Apache Spark

Spark has rapidly become the go-to big data technology globally. Like Hadoop, Spark provides a framework for big data processing with primary difference being its faster operation. Hadoop reads and writes data directly onto disc, while Apache Spark caches computations in memory for instantaneous results. 

 

Apache Spark was originally developed specifically to accelerate complex algorithm execution in data science environments by dispersing processing workload across many machines more effectively and saving time. 

 

Data scientists also use it effectively when dealing with large unstructured datasets, preventing data loss. Its crucial to access this skills when hiring data scientists. Therefore, if you are hiring top data scientists, make sure they possess adequate Apache Spark skills!



3. Familiar with SQL Database

Although NoSQL and Hadoop cover much of data science, you should still expect your candidate to demonstrate expertise with SQL queries. SQL is a programming language designed specifically for data scientists to perform operations like adding, deleting and extracting information from any database. Additionally, it performs analytical functions that transform database structures.

 

SQL was designed to assist businesses in accessing, communicating, and working with large amounts of data quickly and efficiently. When used to query databases for gathering information, SQL provides results. 

 

Furthermore, its short commands save time and  reduce the amount of code needed for complex searches. This skill is crucial for data scientists for hire. When hiring data scientists make sure that they must have expertise in SQL.



4. Strong Understanding of Data Wrangling

Data Wrangling refers to the process by which data scientists prepare raw data for further analysis by transforming and mapping it from one form to the other in order to gain insights. Data scientists use various strategies, including collecting relevant fields together and cleansing the information. 

 

This enables them to focus more on analysis rather than spending too much time on cleaning, leading to accurate data-driven decisions with confidence. It is an essential skill when hiring data scientists - therefore data Wrangling should be part of any successful evaluation of their skill set when hiring process.



5. Experience in Data Visualization

Corporate organizations generate large volumes of data on a regular basis. It must be transformed into easily understandable information using tools like ggplot, d3.js, Matplotlib and Tableau to assist the average employee in extracting insights more efficiently from projects. When hiring dedicated data scientists, ensure they possess strong visualization abilities so your organization can find key insights effortlessly.



6. Basic Knowledge of Machine Learning and AI

Many data scientists lack experience with machine learning techniques and topics like neural networks, reinforcement learning, adversarial learning, and more. If you want your team to stand out, hire data scientists who are familiar with AI and machine learning techniques including supervised machine learning techniques such as decision trees, logistic regression, unsupervised machine learning, time series, natural language processing, outlier detection, computer vision, recommendation engines, survival analysis among others.

How to Write an Effective Data Scientist Job Description?

First, identify what you need and the skills necessary to meet those goals. Next, break the project into individual technologies your data science professional should understand. Use the information in your brief to draft an exhaustive job posting that attracts talents with these capabilities. To start, define three distinct scopes of work:

- Results: What deliverable(s) do you anticipate?

- Targets: When is your submission deadline? 

- Timelines: When are the project's start and end dates?

In addition to highlighting your skills requirements for data science candidates, make sure they're familiar with any tools required for the projects and also familiar with statistical languages such as R/Java/Python or database technologies like Hadoop.

What is the Cost of Hiring a Data Scientist?

Data science is an in-demand field, and qualified data scientists often charge higher rates than other developers or business analysts. Freelance data scientists typically charge anywhere from $36 to $200 an hour with an average project cost of around $400.

Keep in mind that when you require more specialized skills like Scala or Spark the rates will increase accordingly. It might be better to discuss a fixed fee for the entire project.

How to Hire a Vetted Data Scientist?

When hiring a data scientist, first verify their competencies across four areas: statistics, business and communication skills, programming, and production data set experience. Next, you can check their skills relevant to your project: Do they need experience with complex or simple data? Are they proficient in machine learning, etc.? Finally, turn these requirements into an in-depth job description with targeted interview questions to find an ideal data scientist candidate.
