However, companies often fail to utilize their data science resources to maximize returns. This mainly occurs due to the absence of individuals knowledgeable about the data and the business aspects of the industry. Data science consultants possess a unique blend of technical expertise in data science and a deep understanding of business strategy.
They work closely with clients to understand their business challenges and identify opportunities where data science and analytics can be used. They also contribute to developing a strategy that aligns with the business objectives, including data collection, storage, and management. These are unique skills that contribute to a data science consultant’s salary.
The average US data science consultant’s salaries revolve around:
- Data science consultant salary: $166,087 per year
- Data science consultant rates: $200-$350 per hour
- Data science consultant project rates: $5,000 to $7,000 per project
Ultimately, how much you make as a data consultant depends on the location, experience, and the company. Several bonuses also contribute significantly to determining your total compensation and salary. These bonuses often reflect the business value you deliver.
What Do Data Science Consultants Do?
Data science consultants are mostly hired on a per-project basis, but some businesses retain data consultancy firms to receive continuous expert guidance and strategic direction. Here is what data consultants do:
Problem Identification and Requirement Analysis
As a data consultant, you’ll frequently collaborate with clients to identify business problems and opportunities that can be addressed with data science. Your responsibilities include working with technical and non-technical stakeholders to define clear objectives and achievable outcomes for data science projects.
Data Collection and Integration
Due to your expertise in the company’s business and technical side, you’ll identify and gather relevant data for data science projects from various sources, including internal databases, external databases, and APIs. Data integration from these sources is an additional challenge you’re also expected to handle well.
Data Cleaning and Preparation
The data collected for projects often comes in raw format and is in desperate need of cleaning. You’ll be responsible for making these raw datasets free of inconsistencies and errors. As a data science consultant, you’ll also filter the datasets for missing values and create new variables to improve their predictive power.
Model Building and Evaluation
Algorithms selection, model training, and model evaluation fall under the job profile of data science consultants. You should be able to choose appropriate machine learning or statistical algorithms based on the problem and data characteristics while being proficient in training models on the prepared dataset.
Data science consultants also assess model performance using metrics such as accuracy, precision, recall, F1 score, and others.
Monitoring and Maintenance
Continuously monitoring and maintaining model performance to detect and address issues such as drift or degradation falls under your skillsets as a data science consultant. You’re expected to update models with the latest data and manage them based on feedback and metrics.
Training and Support
As mentioned, you’ll also be consistently training client teams on data science tools, techniques, and best practices while providing ongoing support to ensure clients can effectively use data science solutions. Data science consultants must also be proficient in communication to keep clients informed about the latest trends, tools, and technologies in data science and to guide them on long-term strategies and roadmaps.
What Affects Data Science Consultant Salary Rates?
The salary of a data science consultant can vary widely based on several factors. Here are the key factors that affect the rates for data science consultants:
Experience and Expertise
Irrespective of the industry, data science consultants with more years of experience typically command higher rates. Expertise in high-demand areas such as machine learning, AI, natural language processing, or big data analytics can significantly increase rates. Moreover, a proven track record of successful projects and satisfied clients also justifies higher fees.
For instance, a junior-level data science consultant may have to be content with a $81,000 salary, while an experienced individual may attract over $120,000 in base pay.
Geographic Location
Consultants in regions with a higher cost of living, such as major metropolitan areas, tend to have higher rates. Locations with high demand for data science skills, like tech hubs, often offer higher compensation. For example, if you’re working as a data science consultant in San Fransisco or DC, you may command a better rate than, say, Detroit or Atlanta.
