Hire AI developers by skill
To hire an AI developer, test whether they can ship a reliable feature on top of a model: clean data, a measurable evaluation and safe failure, not just a demo notebook. DeveloperHiring tests and interviews candidates and ranks the top five. You keep the hire and pay a flat subscription, not an agency fee.

What does a AI developer do?
AI roles range from applied engineers who build features on top of language models to machine learning engineers who train and serve models. We ask which you need, because the test is very different.
Which AI skills do we test?
The skill matrix for a AI role starts with these six areas. You can change the weights in the role builder.
Model integration
Calling models with structured outputs, timeouts, retries and cost limits.
Retrieval
Chunking, embeddings and search that returns the right context.
Evaluation
A test set and metrics that show whether a change made things better.
Data handling
Cleaning data, removing personal data and tracking versions.
Machine learning basics
Training, validation splits and overfitting, for ML-heavy roles.
Production
Monitoring quality, latency and cost after release.
Which screening questions work for AI roles?
Screening questions go out by email right after a candidate enters the pipeline. Answers are scored against the skill matrix, with a written reason. Here are three from the AI library.
- Q1 How did you measure whether an AI feature you shipped was good enough?
- Q2 A model answer is wrong 10 percent of the time. What do you try first?
- Q3 How do you keep costs predictable when usage grows?
What does the AI coding task look like?
Support answer evaluator. Given a small set of support questions and expected answers, build a scoring script that compares two answer strategies. Time limit 90 minutes.
- Load the labelled test set
- Run both strategies through a provided model stub
- Score answers with an agreed metric
- Report which strategy wins and why
def evaluate(strategy, cases):
scores = []
for case in cases:
answer = strategy(case.question)
scores.append(match_score(answer, case.expected))
return sum(scores) / len(scores)Running hidden tests

The test and the AI interview look for different signals at each level. Use these to set the seniority in the role builder.
| Level | What you should see |
|---|---|
| Junior | Calls a model API and builds a working prototype. |
| Mid | Adds evaluation, error handling and cost limits before shipping. |
| Senior | Owns quality metrics, data strategy and model choice across products. |
How much does a AI developer cost?
Pay varies a lot by country, city, seniority and company. Public salary surveys show broad yearly ranges like these for mid-level to senior AI developers. Treat them as a starting point and check current surveys for your market.
AI and machine learning engineers are among the highest paid developer roles right now, and offers move fast, so short hiring cycles matter.
| Region | Typical range |
|---|---|
| United States | about 130,000 to 220,000 USD and more |
| Western Europe | about 65,000 to 120,000 EUR |
| Latin America and Eastern Europe, remote | about 45,000 to 100,000 USD |
| India | about 20,000 to 60,000 USD |

How does the AI shortlist work?
AI engineers often publish experiments, model evaluations and open source tools. We read public code and write-ups to see real depth. Every candidate then goes through the same screen, the AI task and an AI interview about their own solution. Integrity signals show paste events, similarity and AI code likelihood.
The top five land on your shortlist with a scorecard each. Your team meets them and makes the offer. You keep the hire and pay a flat subscription, from $99 per month billed yearly, not an agency fee.
