The AI Engineering Maturation: From Lab Coats to Launch Pads
Why the Market Is No Longer Hiring “AI Experimenters”
By: Mina Van Piggelen, Director of Operations, Experis, and Rahul Kumar, Regional Director, Experis Europe, with insights from the ManpowerGroup Workforce Intelligence Team
Let’s be honest: the AI world has been a bit of a playground lately. Demos, prototypes, hackathons; fun stuff, but not always useful. Now, the mood is shifting. Fast.
In the past year, we’ve seen a seismic change in what companies want from AI talent. The days of hiring “AI experimenters” are fading. What’s replacing them? A new breed of AI engineer – one who doesn’t just build models, but gets them into production, keeps them running and makes sure they deliver real business value.
At Experis, we’ve been tracking this shift closely. And the data is loud and clear.
The data doesn’t lie
We analysed thousands of job postings and saw a dramatic pivot in the skills employers are prioritising. Here’s what’s hot right now:
- Retrieval-Augmented Generation (RAG): +246.8%
- Prompt Engineering: +112.2%
- Applied Machine Learning: +113.4%
- Multivariate Statistics: +150%
That’s not a typo. RAG is up nearly 250%. Prompt Engineering has more than doubled. And the classics? Still going strong. Applied ML and stats are growing right alongside the new wave. Why? Because LLMs don’t replace foundational knowledge − they build on it.
What today’s AI engineers actually need
It’s not enough to be a brilliant modeller anymore. The best AI engineers today are part data scientist, part software engineer, part DevOps pro. Here’s what’s showing up in job specs:
- MLOps & Operational Excellence: Think CI/CD for models, scalable infrastructure, and automated retraining pipelines.
- Bias Mitigation & Responsible AI: Building fair, transparent and compliant systems isn’t optional − it’s expected.
- Observability & Monitoring: Real-time dashboards, drift detection, and performance alerts are table stakes.
- API-First Engineering: Your model is only as good as its integration. If it can’t plug into a product, it’s not ready.
In short: companies want AI that works. Not just in a Jupyter notebook, but in the wild.
Hiring for impact, not hype
Here’s the kicker: most job descriptions haven’t caught up. They’re still asking for “strong coding skills” and “creative problem-solving”. That’s fine − but it’s not enough.
If you’re hiring AI talent today, you need to ask:
- Can they deploy models to production?
- Do they understand how to monitor and maintain them?
- Have they worked with LLMs, RAG or prompt tuning?
- Can they build responsibly, with bias mitigation and observability in mind?
If the answer’s no, you’re not hiring for impact. You’re hiring for experimentation.
What we’re doing at Experis
At Experis, we’re not just watching this shift, we’re helping to lead it. We’re constantly mapping our talent communities to the skills that matter now. That means:
- Identifying engineers who’ve shipped real AI products.
- Vetting for production-grade experience, not just academic credentials.
- Connecting our clients with talent who can build, deploy, and maintain AI systems that scale.
We’re helping companies cut through the noise and find the people who can actually deliver.
Over to you
If you’re building or rebuilding your AI team this year, ask yourself:
- Are your job descriptions stuck in 2022?
- Are you hiring for prototypes − or for production?
- Do you know what skills are actually in demand right now?
If you’re not sure, or if you want to talk about how to find the right talent, let’s chat. At Experis, we’re here to help you build AI teams that don’t just experiment… they execute.
