TL;DR — As of mid-2026, a senior software engineer in Central and Eastern Europe invoices €38–90K a year on a B2B contract. The equivalent hire in London runs £100–130K base before employer costs, which puts the realistic delta at 40–55% — and because CEE contractors carry no Western-EU-style employer taxes, the invoice is close to the whole cost. Below: salary benchmarks for seven countries, the total-cost-of-hire maths, how to interpret completed-probation results, and the timezone case that usually settles the argument.
Salary benchmarks by country and seniority
The ranges below are annual B2B contractor rates in EUR for engineers working with UK, DACH and Nordic clients. They are aggregated from publicly listed rates on local job boards — Pracuj.pl, NoFluffJobs and Bulldogjob for Poland, DOU and Djinni for Ukraine, eJobs for Romania — plus public salary reports and our own placement data. Treat them as market ranges as of mid-2026, not price points: individual offers move with stack, city and English level.
| Country | Mid (3–5 yrs) | Senior (5–8 yrs) | Staff / Lead (8+ yrs) | Senior vs London/Berlin |
|---|---|---|---|---|
| Poland | €40–55K | €50–85K | €85–120K | ~40–50% below |
| Ukraine | €28–45K | €38–65K | €65–95K | ~45–55% below |
| Romania | €32–48K | €42–70K | €70–105K | ~45–55% below |
| Czechia | €42–58K | €55–90K | €90–130K | ~40–45% below |
| Bulgaria | €30–45K | €40–68K | €68–100K | ~45–55% below |
| Slovakia | €35–50K | €45–75K | €75–105K | ~45–50% below |
| Hungary | €34–50K | €45–75K | €75–110K | ~45–50% below |
Three reading notes.
First, these are contractor invoice totals, not local employment salaries. A Polish engineer employed by a Polish company earns visibly less than the B2B rate the same engineer charges a UK scale-up; the rates above are what you, the Western buyer, actually pay.
Second, the comparison column uses a senior benchmark of roughly £100–130K (~€115–150K) in London and €85–110K in Berlin, which is where publicly listed ranges sat in spring 2026. Those are base salaries; the fully loaded comparison gets worse for London and Berlin, as covered below.
Third, the ranges have drifted up perhaps 5–8% since early 2025 by most public accounts, with the sharpest movement at the top of the senior band in Poland and Czechia. CEE is a sellers' market for genuinely senior people — just a far cheaper one.
What moves an individual offer inside the range:
What the same hire costs in London or Berlin
The 40–55% delta above compares base salaries, which understates the gap, because Western employment carries employer-side costs that CEE B2B contracts do not.
A £115K senior hire in London costs you roughly £15K in employer National Insurance, plus pension contributions, plus benefits — the common finance rule of thumb is 1.2–1.3x base as the fully loaded cost, so £138–150K (~€160–175K). In Germany, employer social contributions add around 20% to a Berlin base of €95K, before benefits and recruitment costs.
A CEE engineer on a B2B contract invoices you monthly, and that invoice is materially the entire cost. The contractor is a registered sole trader — JDG in Poland, FOP in Ukraine, PFA in Romania — and handles their own taxes locally. There is no employer NI, no pension obligation, no statutory benefits bill on your side. €70K invoiced is roughly €70K spent.
Run the full comparison and the fully loaded delta on a senior hire is regularly above 50%, even where the headline salary gap is 40%.
Total cost of hire: the fee model matters as much as the salary
After the salary itself, the biggest lever in the cost of hiring software engineers in CEE is how you pay whoever finds the engineer. Two models dominate the market for Eastern European engineering services.
One-time recruitment fee. A recruitment agency charges a percentage of first-year compensation for the hire, with payment timing set by the engagement. The engineer contracts with you directly. Recruo Standard charges 18% of first-year salary in total: $2,000 at launch, credited toward the fee, and the balance when the hire starts. You can start with one scoped, 60-calendar-day search.
Ongoing markup. Outstaffing and staffing vendors charge a monthly rate with a margin embedded — buyer reports and public analyses suggest typically 30–60% on top of what the engineer actually receives — for as long as the engagement runs. The engineer is employed by the vendor, not by you.
The difference compounds quickly. On a €70K senior engineer over three years:
| Cost line | 18% one-time fee | 30–60% ongoing markup |
|---|---|---|
| Year 1 | €70K + €12.6K fee = €82.6K | €91–112K |
| Years 2–3 | €140K | €182–224K |
| Three-year total | €222.6K | €273–336K |
| Engineer's contract is with | You | The vendor |
| Cost to exit | None — the contract is yours | Buy-out fee, or restart the search |
The markup model buys convenience — payroll, equipment, an office in Wrocław if you want one — and for some teams that is the right trade. But most scale-ups hiring one to five engineers are paying €50.4–113.4K extra over three years on this salary example for admin they could buy from an Employer of Record for typically €500–700 a month.
For the legal setup decision itself — B2B contractor versus EOR versus opening your own entity — see our practical guide to hiring engineers from CEE, which covers it in depth.
Retention and completed probation measure different outcomes
Retention measures whether a hire is still working with the team after a defined period. Completed probation measures the outcome at the end of the agreed probation period, whose length can vary by engagement. A useful comparison needs a clear definition, the number of eligible placements and the period covered.
We do not publish a CEE-specific retention rate. Recruo’s founder reported a company-wide completed-probation pass rate of 100% on 11 September 2026. All placed candidates whose probation has concluded have passed so far. Ongoing probation periods are excluded. The sample size and reporting period are not yet published. This is not a 90-day retention measure or a guarantee of future outcomes.

For your hiring plan, agree the conditions that the team and candidate can review together:
The CEE timezone: a full working day of overlap
If cost is why buyers look at CEE, timezone is why they stay.
CEE spans two zones: CET (UTC+1) for Poland, Czechia, Slovakia and Hungary, and EET (UTC+2) for Ukraine, Romania and Bulgaria — shifting to UTC+2/+3 in summer. In practice, when it is 9:00 in London it is 10:00 in Warsaw and Prague and 11:00 in Kyiv and Bucharest.
That gives a UK team 7–8 shared working hours per day, and a Berlin, Vienna, Stockholm or Helsinki team a fully shared day. Compare the alternatives:
For sync-heavy work — pairing, incident response, sprint ceremonies, architecture debate — the difference between full-day overlap and a three-hour window is the difference between a teammate and a ticket queue. It is also the quiet reason CEE engineers integrate into UK and DACH teams faster than equally skilled engineers three or more zones away.
The AI/ML premium
One important carve-out from the benchmark table: AI and ML roles price above the generalist ranges everywhere in CEE, and the gap widened through 2025–2026.
Publicly listed rates suggest senior engineers with production LLM experience — RAG systems, agent frameworks, eval pipelines, fine-tuning — run 15–30% above the senior generalist band in the same country. As of mid-2026 that puts a senior LLM engineer in Poland at roughly €70–110K and in Ukraine at €55–90K, with staff-level platform and applied-research profiles above that. Scarcity, not geography, sets these prices: the pool of engineers who have shipped LLM systems to production is thin everywhere, CEE included.
The delta against Western equivalents still holds — London generative AI salaries moved even faster — but budget the premium explicitly. If the role you are scoping is genuinely an AI role, benchmark it against the AI band, not the generalist one. We run dedicated pipelines for these searches: see hire LLM engineers and hire generative AI engineers for the profiles and process.

Where this leaves a 2026 hiring plan
The arithmetic is not subtle. A senior CEE engineer at €60–75K all-in, hired for a one-time fee of 18%, against a London equivalent at €160K+ fully loaded plus a 20–25% agency fee — the first-year saving funds most of a second engineer. The honest caveats are the ones this post has tried to price in: budget the real range, pay the AI premium where it applies, choose the fee model deliberately, and keep retention and completed-probation results separate.
Our IT recruitment in CEE page explains how we find engineering talent in Eastern Europe and complete the agreed technical and soft-skill assessment stages before introducing finalists. Standard costs 18% of first-year salary in total, with $2,000 credited at launch and the balance when the hire starts. The search runs for 60 calendar days; if no qualifying finalist is introduced by business day 15, you can stop for a full $2,000 refund. Review the search and 90-day replacement conditions, then scope one role to check the numbers above against your own requirements.
FAQ
How much does it cost to hire a senior software engineer in CEE in 2026?
As of mid-2026, market ranges for senior engineers (5–8 years) run roughly €38–90K a year on B2B contracts, depending on country and stack — Ukraine and Bulgaria at the lower end, Poland and Czechia at the upper. Add a one-time recruitment fee (18% at Recruo) and minimal employer-side costs, and the fully loaded total typically lands 40–55% below an equivalent London or Berlin hire.
Why are CEE engineers cheaper if the quality is comparable?
Cost of living, local salary anchoring and currency — not skill. By most public estimates the region holds roughly 1.1 million tech specialists and adds about 30,000 STEM graduates a year, and its engineers have spent two decades building for Western product companies. The discount is geographic arbitrage, and it is narrowing slowly — around 5–8% annual drift by most public accounts — not collapsing.
What timezone is CEE, and how much overlap does it give a UK team?
CEE sits on CET (UTC+1) and EET (UTC+2), one to two hours ahead of London. A UK team gets 7–8 shared working hours a day; DACH and Nordic teams get a fully shared day. That is full-overlap collaboration, against 1–5 hours for US-based remote hires and 3–4 usable hours for India.
What retention should I expect from remote CEE engineers?
We do not publish a CEE-specific retention rate. Recruo’s founder reported a company-wide completed-probation pass rate of 100% on 11 September 2026. All placed candidates whose probation has concluded have passed so far. Ongoing probation periods are excluded. The sample size and reporting period are not yet published. This is not a 90-day retention measure or a guarantee of future outcomes.
Do AI and LLM engineers in CEE cost more?
Yes. Production LLM and generative AI experience commands a 15–30% premium over the senior generalist band as of mid-2026 — roughly €70–110K for a senior LLM engineer in Poland. The premium is scarcity-driven and exists in every market; the CEE-versus-Western delta still holds at the higher level.
