What the salary data says, and what it does not
BLS does not track “AI engineer” as an occupation, so any single salary figure for the role is somebody’s survey rather than an official statistic. The two occupations closest to the work are:
- Software developers: $135,980 median annual wage, May 2025.
- Computer and information research scientists: $140,300 median annual wage, May 2025 — the occupation BLS describes as working on AI and machine learning.
Both are medians across the whole country and every seniority. A senior engineer who has shipped retrieval and evaluation in production, hired in a large US market, sits above them.
Salary is not the cost
In private industry, wages and salaries are about 70% of what an employer spends on compensation; benefits are the other 30% (BLS, June 2026). Carried through, as arithmetic:
| Median salary (BLS, May 2025) | Full compensation cost a year | Per month |
|---|---|---|
| Software developers, $135,980 | about $194,000 | about $16,200 |
| Computer and information research scientists, $140,300 | about $200,400 | about $16,700 |
That is before recruiting fees, equipment, management time and the months the seat stays empty while you hire — none of which we have a published figure for, so none is added here.
Four ways to get AI engineering capacity
| In-house hire | Team extension | Managed project | Freelancer | |
|---|---|---|---|---|
| What you pay | About $16,200–$16,700 a month at the US median, fully loaded | $4,000–$7,000 per engineer per month | $15,000–$30,000 a feature; $40,000–$120,000 a product | An hourly rate; it varies too widely to quote |
| Commitment | Open-ended | Three months, then rolling | One defined scope | Per task |
| Time to start | Months | 1–2 weeks | Scope within 48 hours of a call | Days |
| Who directs the work | You | You | The vendor, against the scope | You |
| What you risk | A mis-hire, found out after a quarter | A poor fit, found out in the first month | A scope that was wrong to begin with | Continuity when they move on |
As an hourly figure, $4,000–$7,000 a month is $25–$44 an hour at 160 working hours. That is arithmetic on our published band, not a separate rate, and we do not bill by the hour.
Why team extension costs less, and what you give up for it
The gap in the table is not a discount on skill: the band moves with seniority, not stack, and the engineers are senior and mid+ only. It is that the employment overhead sits with us rather than with you, and that you are buying a month of an engineer rather than a career.
What you give up is real, and worth naming before you choose:
- They are not your employees. The knowledge stays in your codebase and your documentation, not in your headcount.
- Three months is the floor. Below that, onboarding eats most of the value on both sides.
- Overlap is CET and US Eastern hours. A team on the US west coast gets partial overlap; one in Asia-Pacific gets little, and we would rather say so than promise otherwise.
What an AI engineer should be able to show you
Whichever route you take, the interview question that separates an AI engineer from someone who has called a model API is the same: what did a system you built cost per answer, and how fast was it to the last token? On ours the answers are about $0.011 and 1.9 seconds, with the conditions published on the case study. An engineer who has run something in production knows their numbers; one who has not will talk about models.
When hiring in-house is the right answer
- AI is the core of the product for years, not one feature in it.
- You can wait the months a good hire takes.
- Someone on your side can lead them — a first AI hire with nobody to set direction is the expensive version of drift.
If all three hold, hire. If the first holds and the other two do not yet, extending your team while you hire is the usual bridge; if you need one defined thing built, managed AI development is.
