How to Benchmark Software Engineer Salaries Across Countries

If you are setting a salary band for a senior backend engineer in Warsaw, Lisbon, Bucharest or Istanbul, the honest answer is that no public dataset will give you a number you can defend. Aggregator sites mix local-employer and foreign-employer pay, mix gross and net, mix base and total, and lag the market by six to eighteen months. The usable approach is to triangulate: your own offer and accept history, live deal flow from recruiters working that market this quarter, candidate-reported current compensation, and public data as a sanity check only. Then normalize everything to total cost of employment before you compare anything.

Here is how to do that without building a compensation function you don't have the headcount for.

First decide which market you are actually competing in

In every one of these cities there are two separate labor markets for the same engineer, and they price differently.

The first is local employers — banks, telcos, system integrators, domestic product companies. The second is foreign buyers: US, UK, German and Nordic companies hiring remotely or through an entity, plus well-funded local scale-ups that index to foreign pay. A senior Java engineer in Bucharest with solid English and distributed-systems experience is usually choosing between the second group, not the first.

This distinction destroys most benchmark reports, because they blend both populations into one median. If you are hiring from the second pool and you benchmark against the blended median, every strong candidate you reach will be above your band, and you will conclude the market is "irrational." It isn't. You pulled the wrong sample.

So write down, before you look at any data: which employers will this candidate have offers from? Benchmark against those, and only those.

Normalize to total cost of employment, not base

Base salary comparisons across borders are close to meaningless. The structure of pay differs enough that a 10% base gap can flip direction once you add everything up.

Things to normalize before you compare two markets:

• Mandatory extra salary payments. Portugal pays holiday and Christmas subsidies, which in practice means fourteen payments rather than twelve. Greece has a similar structure. If you quote a monthly figure in one market and an annual figure in another, you will be off by roughly 17% and never notice.
• Employer social contributions. These vary widely and are the single largest hidden variable. Ask for the employer burden as a percentage, with any caps or ceilings, for the exact salary level you are hiring at — caps matter enormously at senior pay.
• Benefits that are effectively mandatory by custom. Private health insurance in Turkey and Romania, meal vouchers or meal allowances in Romania and Portugal, transport contributions. They are not legally required in every case, but an offer without them reads as cheap.
• Severance accruals. In Turkey, severance pay is roughly one month's gross salary per year of service for qualifying terminations, subject to a statutory ceiling. That is a real liability accruing from day one and it belongs in your cost model even though it never appears on a payslip.
• Employment form. In Poland and Romania, a large share of senior IT talent works on B2B contracts rather than employment contracts, for tax reasons. The headline rate on a B2B contract and the gross salary on an employment contract are not comparable numbers, and converting between them requires local tax input.
• Equity. If you grant options, ask what the candidate pool actually values them at. In markets where local exits are rare, discount heavily — many candidates will price your options at zero and you should know that before you build a band around them.

Build the band from four inputs

Your own data first. Every offer you have made, the band it sat in, whether it was accepted, and what the candidate's competing offer was. Ten data points from your own funnel beat a thousand scraped ones, because they are the only data that describes your company, your brand, and your role. If you are not capturing competing-offer detail at the close stage, start this week; your ATS and HRIS setup should hold it as structured fields rather than recruiter notes nobody can query.

Live recruiter deal flow second. A recruiter running senior backend searches in Istanbul right now knows what candidates are refusing, what they are accepting, and how fast expectations are moving. Ask for the range of accepted offers in the last quarter for the specific seniority and stack, not a blended average. When we run technical and specialist searches across markets, this is the number that actually settles pay debates — not a report, but a list of what was signed.

Candidate-reported compensation third. Current pay plus expectation, collected at screening. It skews high on the expectation side and unreliable on the current side, but the distribution across twenty candidates tells you where the market sits and how wide the spread is. The spread matters: a tight spread means a commoditized profile; a wide one means seniority titles in that market are not informative and you must price the individual.

Public aggregators last, as a boundary check. If your band is wildly outside every public source, something is wrong with your assumptions. If it is somewhat above, that is normal for foreign buyers.

Currency, inflation and review cadence

Pay in a market with high inflation cannot be managed on an annual review cycle. Turkey is the clearest case: an annual increase set in January is materially eroded by mid-year, and engineers there are used to employers adjusting more than once a year. If you run a global annual cycle and apply it uniformly, you will lose people in that market for reasons that have nothing to do with the quality of your offer.

Two workable patterns: review that market semiannually, or denominate the band in EUR or USD and pay the local-currency equivalent, which transfers FX risk to you rather than the employee. Both are defensible. What is not defensible is applying one global cadence and discovering the problem through resignations.

Decide how bands relate across countries — before anyone asks

You have three options and each has a cost. A single global band is simple and avoids the "why does Marcin earn less than Mark" conversation, but overpays in lower-cost markets and burns budget you could have spent on headcount. Fully local bands are efficient and the standard approach, but create visible internal gaps on the same squad — and engineers on the same standup compare notes. Location factors applied to a reference market split the difference and require you to explain the factor, which is a conversation worth preparing for.

There is no right answer, but pick one deliberately and write down the reasoning. The damage comes from drifting — hiring the first three people in a market on ad-hoc numbers and then trying to retrofit a structure. If pay structure is becoming a visible fairness issue on your teams, it is really a culture and transparency problem as much as a compensation one.

Sanity checks that tell you the band is wrong

You do not need a survey to know your band is off. Watch four signals:

• Offer accept rate by band. Below roughly two in three at the senior level, with losses to competing offers rather than counteroffers, means you are underpriced.
• Where candidates drop out. If expectations kill the process at screening rather than at offer, your band is below the market's entry point and you are wasting recruiter time.
• Counteroffer losses. Losing people to their current employer is usually a role and growth problem, not a pay problem. Don't fix it with money.
• Twelve-month regrettable attrition. People who leave within a year for a modest raise were underpaid at hire.

Two final notes. Executive compensation does not work this way at all — there is no usable public data for a VP Engineering or CTO in most of these markets, the sample is tiny, and packages are negotiated individually, which is why director and C-level searches are priced from recent comparable deals rather than bands. And if your reason for hiring abroad is purely cost arbitrage, run the full cost-of-employment math including severance accruals and management overhead first; the gap is usually real but smaller than the base-salary comparison suggests.
