They build things that are accessible and made to scale. They keep our systems in the best shape by simplifying the unnecessary complexity. We make the decisions as a team and group of teams for our ways of working and we take architectural decisions together. Everyone plays a role in our future. Our Engineers choose the best technologies that work for Wolt, their teams and themselves. Making good choices means finding scalable, robust technology that works in everyone’s best interests.

Pre-apply checklist

Quickly verify the listing has the essentials so you can compare offers fairly.

Is the salary gross or net, and what period is it for?
Is it employee (CIM) or contractor (B2B/PFA/SRL)?
What does “remote/hybrid” mean in practice (office days, overlap)?
Is the scope and seniority level clear?

How to read these numbers

This page uses only listings that publish a salary range (min–max). The “average” is estimated as the midpoint (min+max)/2, aggregated across salary listings.

Use the range as an anchor for negotiation, then open recent listings to understand seniority, stack, and typical responsibilities.

How to use these insights

Use the distribution to understand typical salary bands (not just averages).
Compare experience levels and technologies to calibrate negotiations and career moves.
Use the tools to estimate take-home pay (CIM) or contractor outcomes (PFA/SRL).

Important caveats

Charts use job listings with explicit salary ranges; not all jobs disclose pay.
Averages may use midpoints of ranges for aggregation.
Location, remote policy, and seniority labels come from listings and can vary by company.

Methodology (short)

Data sources

We aggregate and analyze salary ranges from IT job listings published on IT Jobs List. Some listings include salary bands explicitly; others may not.

Active job listings on IT Jobs List
Salary ranges provided by employers (when present)
Job metadata (role, seniority, location, tech stack) used to group and compare results

Normalization and assumptions

To keep comparisons useful, we normalize the way we interpret listing data across companies.

Salary figures are displayed in EUR where possible; listings may use different currencies and compensation structures.
When a listing provides a range, we may use the midpoint for aggregate charts.
Remote/hybrid/office and employment type are taken from the listing and may differ across teams within the same company.

Limitations

These insights reflect the market as described by listings, not private compensation data.

Not all jobs publish salary ranges, so some segments may be under-represented.
Job titles vary between companies; we group them, but edge cases exist.
Outliers can appear; trends are more reliable than any single datapoint.
