The first question almost every US hiring manager asks about a European engineer is some version of “how does this even work legally.” The honest answer is that it is simpler than hiring someone in another US state, not more complicated. There is no visa, no sponsorship, no relocation, and no payroll to set up. What follows is the actual structure, including the parts people worry about and the parts they actually should.
It is a contractor relationship, not employment
The engineer invoices your company as an independent contractor, usually through their own registered business in their home country. You are not their employer. That means no US payroll, no W-2, no benefits administration, and no registering your company in a state where you otherwise have no presence. For a senior engineer in Prague, Brno, or Bratislava, this is the normal way they already work with foreign clients. They handle their own income tax and social contributions at home. Your side of the relationship is purely commercial: a signed agreement, a monthly invoice, and net-30 payment.
Two documents do most of the work
The paperwork people imagine is heavy is actually light. A straightforward services agreement defines the scope, the rate, the intellectual property assignment, and confidentiality. Then the contractor signs a W-8BEN (or W-8BEN-E if they invoice through a company), which confirms they are a non-US person performing the work outside the US. That form is what lets you pay the full invoice without withholding US tax and without issuing a 1099 at year end. Your accountant has processed both documents many times. Nothing here is exotic.
IP and confidentiality hold up better than people assume
The quiet fear is that putting an engineer in another country weakens your control over the code they write. In practice the services agreement assigns all work product to your company on creation, exactly as a US contractor agreement does, and EU jurisdictions enforce both IP assignment and non-disclosure. Czech and Slovak engineers who work with US clients sign these routinely and expect to. The larger real risk is not the border. It is the same risk you carry with any hire: whether you vetted the person properly before you trusted them with the work.
What it costs you, and what it does not
You pay the contract rate and, on placement through a firm like ours, a one-time placement fee. You do not pay employer payroll tax, health and dental premiums, a 401K match, equity dilution, recruiter retainers, or office cost per seat. Those line items routinely add 40 to 60 percent on top of a US base salary, and they disappear here. The engagement also ends cleanly if the fit is wrong: no severance, no unemployment claim, no months of process. You get senior output on a clean commercial agreement, and you keep your optionality.
