Data Science Specialist is listed under occupation code 252909 in Database and network professionals not elsewhere classified. A practical reading of the role starts with “Analyze the data sources to make applicable recommendations in data science” and the evidence needed to use Data processing and analysis reliably.
Official title: Data Science Specialist
Occupation code: 252909
Mahana sector: Data and artificial intelligence
Official unit group: Database and network professionals not elsewhere classified
How to read the Data Science Specialist responsibility
The classification places Data Science Specialist in Data and artificial intelligence under code 252909. Use that baseline, then test how a real employer handles both “Analyze the data sources to make applicable recommendations in data science” and “Issuing the strategic insights related to data science based on the analyses of large…”.
Do not assume every employer means the same thing by Data Science Specialist. Check seniority, supervision, the effect of mistakes, and whether Data modelling is an entry requirement or developed after appointment.
Official scope and recorded tasks
Official summary: Examine the data from many different sources; design and implement custom algorithms, workflow processes and schemes for large-scale complex data sets used for modeling; and conduct data mining and research.
Recorded tasks
- Analyze the data sources to make applicable recommendations in data science.
- Issuing the strategic insights related to data science based on the analyses of large data sets.
- Provide thoughtful recommendations and practical solutions in the field of data science, based on data analysis and results.
- Issue and implement data mining and data warehouse programs.
- Display the data in innovative formats.
Skills in working context
- For Data Science Specialist, connect Data processing and analysis to a situation involving “Analyze the data sources to make applicable recommendations in data science”, then state the acceptance test and who reviewed the result.
- For Data Science Specialist, connect Data modelling to a situation involving “Issuing the strategic insights related to data science based on the analyses of large…”, then state the acceptance test and who reviewed the result.
- Test Data warehouse through a bounded code-252909 case involving “Provide thoughtful recommendations and practical solutions in the field of data science, based on…”. Record the inputs, likely failure, and correction method.
- Use an example from Data Science Specialist work for code 252909 that connects Data analysis to “Issue and implement data mining and data warehouse programs”, separates your contribution from the team result, and names the decision you owned.
When presenting experience related to code 252909, separate your role from the team's and show how Team Work, Ability to build relationships, Analytical Thinking protected quality or delivery.
A contained evidence project
Test one bounded part of Data Science Specialist work without presenting the exercise as independent professional practice. Start from “Analyze the data sources to make applicable recommendations in data science”, use Data processing and analysis, and record what changed after review: Use occupation code 252909 to bound the exercise: Frame a narrow prediction or classification problem, prepare a reproducible baseline, compare one alternative, and document evaluation limits and responsible-use considerations. Include one check connected to “Issuing the strategic insights related to data science based on the analyses of large…”.
- Data Science Specialist evidence: For Data Science Specialist, limitations and monitoring note linked to “Issuing the strategic insights related to data science based on the analyses of large…”
- Data Science Specialist evidence: A working output showing how Data processing and analysis supports “Analyze the data sources to make applicable recommendations in data science”
- Data Science Specialist evidence: A code-252909 review note that records one challenge, correction, and remaining limit
Pitfall to avoid: For code 252909, avoid optimising a metric without checking data leakage, representativeness, operational cost, or how the result will be used. The missing evidence usually appears when “Analyze the data sources to make applicable recommendations in data science” is reviewed.
Methods or tools that may appear
- Data processing and analysis
- Data modelling
- Data warehouse
- Data analysis
- Data collection
Check a vacancy for Data Science Specialist before applying
Begin with vacancy responsibilities, not keyword count. For Data Science Specialist, identify what the employer expects during “Issuing the strategic insights related to data science based on the analyses of large…” and how that capability will be assessed.
- Identify the output that demonstrates Data processing and analysis and the person or standard that approves it.
- For the Data Science Specialist vacancy under code 252909, map one line to “Issuing the strategic insights related to data science based on the analyses of large…” and prepare a truthful example you can explain under questions.
- For Data Science Specialist, code 252909, confirm whether Bachelor degree is an employer or regulator minimum and what supervision applies at entry level.
Qualification and practice boundaries
Qualification in the classification data: Bachelor degree
- Database and network design and administration
Questions to test career fit
- Would I enjoy repeating “Analyze the data sources to make applicable recommendations in data science” in day-to-day Data Science Specialist work, not only once in a practice project?
- For the Data Science Specialist path under code 252909, can I build evidence for Data processing and analysis that shows the decision and check, or am I mainly attracted to the name of Data and artificial intelligence?
- What qualification, registration, supervision, or employer requirement currently applies to responsibilities under code 252909?
- Which part of the Data Science Specialist evidence project will I test first, and what result would make me continue or change direction?
