Data engineer to data quality specialist
A data engineer already meets 17% of what the data quality specialist role asks for. The move turns on 16 required skills not yet in the profile.
81.7/ 100
1 How much of what a data quality specialist is expected to do is already part of a data engineer’s work. Directional: the figure for the reverse move differs, because moving into a speciality is not the same problem as moving out of one. 2 Every skill the data quality specialist role is recorded as needing, required and optional together. What these numbers mean.
Why this move works
A data quality specialist role treats 4 of its required skills as things a data engineer already does. You would walk in with these on day one.
- establish data processes
- manage data
- process data
- use data processing techniques
What stands in the way is 16 required skills the profile does not yet cover. Table 3 groups them; Table 4 says which to take first.
Table 2 · What you already bring
Of the 6 skills that carry over, these are the ones fewest other occupations ask for. A data quality specialist role needs them, and most people applying for one will not have them already. This is the part of a data engineer background worth leading with.
- already held establish data processes working with computers
- already held design database in the cloud communication, collaboration and creativity
- already held use data processing techniques working with computers
- already held manage data information skills
- already held process data information skills
- already held statistics natural sciences, mathematics and statistics
All 6 carried skills, including the 4 the data quality specialist role treats as required.
Table 3 · What you may need to learn
The 34 missing skills fall into 8 areas of the ESCO skill hierarchy, numbered in the order worth working in. Areas carrying the most required skills come first, and inside each one the required skills sit above the optional ones. Nothing here is a verdict on you: it is a list of what this particular job asks for that your current one does not.

Common questions about this move
Can a data engineer become a data quality specialist?
Yes, and it is a career change move. A data engineer already covers 17% of what a data quality specialist is expected to do: 6 skills carry over, 4 of which the data quality specialist role treats as required.
What skills does a data engineer need to become a data quality specialist?
16 required skills are missing, plus 18 optional ones. They fall into 8 areas of the ESCO skill hierarchy, led by information and communication technologies (icts). The single most important is utilise regular expressions.
How hard is the move from data engineer to data quality specialist?
Its learning distance is 81.7 out of 100, which is the career change band. That accounts for both how much is missing and how specialised those skills are.
How this record was compiled
Both occupations are taken from ESCO, which lists the skills and knowledge each occupation is expected to have and marks every one required or optional. Nothing here is a prediction about hiring, and nothing here knows that a particular employer wants a particular certificate. Treat Table 3 as a starting point for your own research rather than a syllabus. The full method states what these figures can and cannot tell you.
