Headline day rates for a senior engineer run from roughly €150 to €1,200 depending on where the engineer sits, and the cheapest market on the rate card is often still the cheapest market after adjustments. The gap closes only under specific conditions: unstable requirements, decisions that need same-day answers, or work that cannot be parcelled into independent tickets. Knowing which of those applies to your project is the whole decision.
On AI and data work the spread is narrower than on generic backend work, because engineers who have shipped a retrieval system or a production feature store are priced by global demand rather than by their local salary floor.
Indicative senior day rates by market
Bands are for an engineer with six or more years of experience, billed time and materials through a supplier that carries employment risk. Marketplace freelancers price 10% to 25% below this and carry no bench, no cover and no contractual liability.
| Market | Senior day rate | Overlap with CET |
|---|---|---|
| South Asia | €150–300 | 3–5 hours |
| South-East Asia | €200–350 | 2–4 hours |
| Latin America | €350–600 | 3–5 hours |
| Eastern Europe (EU member states) | €400–700 | 8–9 hours |
| Southern Europe | €450–750 | 9 hours |
| Germany, Netherlands, Nordics (local contractor) | €700–1,100 | 9 hours |
| UK and US (local contractor) | €750–1,400 | 0–8 hours |
Add 20% to 40% for scarce AI and data specialisms in every one of those markets: LLM application work, streaming platforms, MLOps at scale. Our live figures for AI, data and Python roles sit on the daily rates page, which we keep current rather than quoting numbers here that go stale.
Why the same job title costs three times more in one country
- The local salary floor plus statutory employer cost. A supplier must pay enough to keep the engineer from leaving, then add social contributions and payroll taxes, which run 20% to 35% on top of gross pay across most of the EU.
- Competing demand in hard currency. Where local engineers can bill US or UK clients directly, the domestic floor tracks those rates, not local cost of living. This is why Poland, Romania and Portugal have all moved up two bands in a decade.
- Skill scarcity rather than seniority. A senior Java developer and a senior ML engineer with the same years of service can differ by 50% in the same city.
The costs that never appear on the rate card
Compare two quotes on effective cost per delivered month, not per hour. The lines that move it:
- Overlap. Two hours of overlap means one question per day gets answered. Seven hours means a blocker is cleared before lunch. On exploratory AI work, where the spec changes as you see the first evaluation results, that difference shows up as weeks.
- Rework, anywhere from 5% to 30% of output, driven almost entirely by how precisely the work was specified.
- Your own senior time. A far-shore team with thin overlap typically absorbs 30% to 50% of an in-house architect’s week; a nearshore team with full overlap absorbs 10% to 15%.
Take three senior data engineers for six months. At €220 a day, a month of a four-person far-shore squad costs about €18,500; the same month with three EU-based engineers at €520 costs about €32,800. Charge your architect’s time at a loaded €600 a day and the first option rises to roughly €23,500, the second to about €34,000. The far-shore quote is still 30% cheaper. It stops being cheaper when rework passes about 25%, or when the calendar matters more than the budget, because you cannot buy back a quarter.
Where the European rate is the wrong purchase
If the work is well specified, parallel and stable for months (test automation, connector building, a migration with a frozen source schema), pay the lower rate. If you need 40 engineers by next quarter, we cannot staff that and larger offshore providers can. If procurement demands a fixed price for a fixed scope, read what an hourly consulting rate actually pays for first.
Where the higher rate earns its money: one team, EU jurisdiction and GDPR without an adequacy argument, and same-day decisions. The nearshore versus offshore comparison covers those trade-offs, and the project cost calculator will size a team against a budget in euros.
Before you compare two quotes
Ask both suppliers for a rate card by seniority rather than one blended number, whether project management and QA sit inside the rate, notice period and replacement terms, and the currency plus any indexation clause. A quote missing the last two is not a quote you can compare.
