Hiring a full-time senior AI engineer
A full-time senior AI engineer in 2026 costs $250k–$400k all-in (US, base + equity + benefits) and takes 4–9 months to hire if you are competing with FAANG and well-funded startups. That math works at scale; it does not work for a single bounded project. Here is the comparison.
Side by side
| full-time hires | Mini Trends | |
|---|---|---|
| Time to first commit | 4 – 9 months (hire) + 6 weeks ramp | 5 – 10 business days from brief |
| Cost (one project, $100k scope) | $320k all-in / yr × time-on-task | $100k fixed |
| Cost (ongoing engineering need) | $320k / yr × N engineers | $30k / mo Embedded Principal |
| Recruiter / agency fees | 20 – 30% of base | $0 |
| Failed-hire risk | ~30% within 12 months | First week refundable |
| Senior judgment from day one | After ramp | Day one |
| Variety of past production AI shipped | 1 – 3 systems typically | 14 systems shipped, 3 active per quarter |
| Best for | Long-term, full-time engineering capacity | Bounded projects + interim leadership |
When each is the right call
Pick full-time hires when…
- You have ongoing AI engineering work that justifies a permanent role
- You are building a long-term AI team and need a founding senior to anchor it
- You can wait 4–9 months for the hire and afford the recruiting and ramp cost
- You are willing to absorb the ~30% failed-hire risk that comes with senior IC hiring
Pick Mini Trends when…
- You have a bounded project that needs to ship in this quarter, not next year
- You want senior judgment without a full-time commitment
- You are pre-hire and want to use us as a force multiplier for the existing team
- You want a fixed-price engagement instead of a salary line item with unbounded scope
These are not mutually exclusive. The most common path we see: hire us to ship the first production AI system, then hire a full-time senior to take it forward — often someone we help you interview. We have no interest in being your forever engineer. We are interested in being the right engineer for this quarter.
