A senior software engineer in Prague earns between $60,000 and $90,000 annually in the local market. A senior engineer in San Francisco earns $160,000 to $220,000 in base salary, before you count equity, benefits, payroll taxes, and the 18 months you’ll spend backfilling the role when they leave for a better offer. These numbers sit next to each other in a lot of conversations about hiring Eastern European developers, usually in a way that implies the value is in underpaying the engineer. That framing is wrong, and it’s worth unpacking why.
The engineer isn’t the savings
Czech engineers working with US tech companies through CzechDevUSA earn $80,000 to $125,000 annually — two to three times the local Prague market rate for equivalent experience. This isn’t charity. It’s market rate for a US-facing remote role with US timezone overlap. The engineers know their value, and the compensation reflects it. The savings to the company don’t come from the engineer’s number. They come from everything around it.
A US-based W-2 senior engineer at $160K base costs the company significantly more in total. Employer payroll taxes add roughly 7-10%. Benefits — health, dental, vision, 401K match — add another $20-30K depending on the plan. Office costs for a hybrid or in-person role add more. Equity at a meaningful level adds dilution and accounting complexity. The total cost of a $160K US engineer is frequently $200-230K when you account for all of it. A Czech engineer at $100K as an EU-based contractor eliminates every one of those line items. The engagement is clean: a single annual contract, net-30 payment terms, no employer-side tax complexity.
The tenure multiplier
The second savings that never gets calculated properly is turnover. The average US senior engineer tenure is 18 months. Every replacement cycle costs the company three to six months of productivity loss, recruiter fees of $30-50K, onboarding time, and the institutional knowledge that walked out the door. Czech engineers working in remote roles with US companies average three to four years in the same position. At that tenure level, you’re not just getting a cheaper engineer — you’re getting an engineer who actually compounds. Someone who understands the codebase, the team dynamics, and the product deeply enough to make good architectural decisions independently.
Run the numbers on a two-year window. A US engineer at $210K all-in total cost, replaced once, with a three-month gap and a $40K recruiter fee, costs roughly $470K over two years. A Czech engineer at $100K annual, still in the role at the two-year mark, costs $200K over the same period. The gap isn’t $60K. It’s closer to $270K when you account for what you stop spending on the revolving door.
What this actually means for a hiring decision
The decision to look at Czech or Slovak engineers isn’t a decision to pay less for talent. It’s a decision to change the structure of what you’re paying for. The engineer is paid well — significantly above their local market. Your company pays less in total than it would for a US equivalent, not because the engineer’s rate is lower, but because the surrounding cost structure collapses. That’s the actual argument. It holds up under scrutiny, which is why it’s worth making precisely.
