About
How On The Spot Development vets AI engineers
On The Spot Development hires engineers who ship AI products to production. We evaluate candidates' fundamentals, breadth, and ownership. We prioritize architecture, data, testing, and release processes.
On The Spot Development builds AI practice into its management layer: at Team Lead Club, a regular meeting of engineering leaders sharing what worked and what didn't in AI adoption, and TechSpot meetups cover AI systems in production. We use this experience to define and pre-screen every AI role.

Why On The Spot Development
Why hire dedicated AI developers through On The Spot Development
No hidden markups
You see what an AI engineer costs: the full gross salary and a fixed management fee, as two separate lines on every invoice.
Full operational support
Your AI engineers work in Poland, and you need no legal entity there. On The Spot Development is the employer and covers HR, payroll, legal administration, office, equipment and day-to-day support.
A team you control
You choose every AI engineer and lead the technical work, from model choices to code review. You see each candidate's stage and recruiter feedback throughout hiring.
Flexible long-term setup
Add or swap AI engineers as the roadmap grows. A buyout right from day one lets you move the team into your own company, with the process set in the contract.
Knowledge stays yours
Each AI engineer works on your product only and never rotates to other customers or teams, so knowledge of your models, data and codebase builds up in your team.
On-demand leadership
On The Spot Development hires team leads as well as engineers. Until you have a senior lead, CTO as a Service engagement covers architecture and model decisions.
Engagement models
Two ways to hire AI engineers
Tech recruitment
The AI engineer is hired directly by your company. We manage the sourcing and technical pre-screening for a fixed success fee.
Honest assessment
When hiring AI engineers through On The Spot Development fits
We turn down engagements that are not the right fit. Here is how to know whether this is the right moment for your company.
Right Moment
Your AI roadmap grows faster than your team. Local AI and backend roles at your target salary are hard to fill. On The Spot Development starts from 60,000+ engineers in its database and contacts AI engineers who aren’t applying anywhere.
You want AI engineers embedded in your team. They work in your repositories and sprints, in the code around your models and data.
Your AI product needs people who stay. Context on your data, pipelines and model behavior in production takes months to build. Keeping it costs less than rebuilding it.
The shape of the team will change. Start with the roles that unblock the roadmap, such as an AI engineer and a backend engineer, then add or swap roles as the product demands.
Probably Not Yet
You are still deciding what to build with AI. If the architecture, the model choice and the first hires are open questions, start with CTO as a Service and hire the team once the plan is clear.
You need a fixed-scope AI project for a fixed price. A project outsourcing vendor fits this better.
You are hiring one AI specialist. Tech recruitment services fit better: On The Spot Development finds the person, and you employ them.
You need an AI expert for a few weeks. Every engineer is hired from the market for your team, and there is no bench of specialists. The search takes weeks, rare AI roles take longer, and a short task would end before the new hire is up to speed.

FAQ
Hiring AI developers: frequently asked questions
How much does it cost to hire an AI developer?
On The Spot Development charges the engineer's gross salary plus a fixed management fee. Both lines appear on the invoice, so you see what the engineer earns and what the service costs. The salary depends on the role, the seniority and the market in Poland. The fee stays fixed and doesn’t grow as a percentage of salary.
What does the management fee include?
The fixed management fee from On The Spot Development covers recruiting, HR, office space, equipment, payroll, legal support and account management in Poland. Your team spends its time on the product. Hiring logistics, employment contracts, hardware and payroll for the engineers you hire in Poland stay with On The Spot Development.
What AI roles can I hire through On The Spot Development?
On The Spot Development hires AI engineers, AI architects, Python developers for AI products, and AI enablement engineers. An AI developer usually builds features on top of existing models, while an AI engineer also designs and runs the AI system itself. Every search starts from the tasks in your brief.
How fast can I see AI engineer candidates?
On The Spot Development typically sends the first CVs within 3–5 working days of the brief. Recruiters search the company's own database, open-source repositories and Slack and Discord communities in parallel. Rare AI roles take longer to close, and the full hire depends on your interview process and the candidate's notice period.
What happens if an AI engineer leaves?
If an engineer leaves, On The Spot Development restarts the search for the role. Candidate data, interview feedback and the role profile from the first search carry over, so the new search usually moves faster.
Can an AI startup hire through On The Spot Development?
Yes. On The Spot Development builds teams for early-stage AI startups as well as established product companies. A team can start with a few engineers and grow with the roadmap. If the architecture and model choices are still open, CTO as a Service covers them before the first hires.
Who owns the IP the engineers create?
Under an On The Spot Development contract, you own the IP. Rights transfer at the moment the code is created. The developer assigns them to On The Spot Development, and On The Spot Development assigns them to you under the customer contract. The transfer doesn't wait for a milestone, an invoice or the end of the engagement.
How does the buyout right work?
On The Spot Development gives you a buyout right from day one. You can move the engineers onto your own payroll, and the right is not tied to a term or a milestone. The buyout process is defined in the contract from the first day, so both sides know the terms before the team starts.
Why hire AI developers in Poland?
On The Spot Development hires in Poland for its large engineering market, EU-level contract and IP protection, and GDPR by default. For UK and European companies, Poland is a nearshore location in CET with working-hours overlap. Engineers work from the Warsaw office, remotely or in a hybrid format.
Can I hire AI talent in Poland through a local recruiter?
Yes. On The Spot Development has in-house recruiters in Poland. Through an offshore development center, we hire the engineers and employ them in Warsaw. If you have your own entity, tech recruitment services find the candidate and the contract is with your company.
