You hire a back-end developer.
The code ships.
The demo works.
Then, three months later, something has to change, and you find out the person who built it has never owned a system past launch.
It's one of the most expensive hires a founder can make, because you don't see it coming.
The problem: bad engineering hides
Every other role gives you a tell.
You can hear a salesperson on a mock call.
You can pull up a media buyer's ROAS. You can read a copywriter's work in ten minutes.
An engineer's mistakes stay invisible until the product needs to grow. By then you've paid for three months of work, and the fix often starts with rebuilding what they built.
We call this the Marketplace Senior. The title is accurate on the profile and nowhere else.
Why it keeps happening
A founder told us recently that he could get a back-end developer out of LatAM for $4,500 to $5,000 a month. He's right. He can.
Here's what that money actually buys, from our own hiring desk this month:
Monthly cost | Who you get |
$4,500 to $5,000 | A strong full-stack developer (Serbia, offer accepted) |
$7,600 | A senior back-end lead with 20+ years' experience (Poland) |
~$14,600 | The median US back-end developer ($175,000/yr) |
The founder's number is real. It just buys the first row, and he's hiring for the second.
That second row spent four years building a bank's market-risk platform, the kind of system whose numbers end up in reports to regulators. That's what you're paying for.
Same job title, different person. Hire a mid-level developer for a senior job and the region gets the blame.
What getting it wrong actually costs
At $4,500 a month, three months with the wrong hire is $13,500 before you've even found the problem. Then comes the rebuild, and then you start hiring again. The right senior costs more up front and still comes in at about half the US price.
How to spot it before you hire
Most non-technical founders screen for stack keywords: Python, Django, Postgres, AWS. Every candidate lists them, because every candidate knows to.
Two questions tell you more:
"Tell me about a system you owned for more than a year, and what broke."
Anyone can build something. Very few have lived with what they built. You'll hear about a specific outage and a specific fix, or you'll get a vague answer."Talk me through a tradeoff you got wrong."
Seniors have plenty of these and don't mind telling you. Juniors haven't made a decision big enough to regret.
You don't need to be technical to hear the difference.
How we take this off your plate
You don’t have to become a technical interviewer to hire one engineer. That's our job.
When we interviewed that Polish engineer, we didn't start with his tech stack. We asked him to walk us through the systems he'd built and what his part in them was. That's the screen.
You get a shortlist of 3 to 5 candidates in 7 to 10 days, and we place in under 23 days. You hire them directly and pay a once-off flat fee.
The placement also carries a 120-day replacement guarantee.
What you get is one engineer, hired once, who's still there in year two.
