Why On The Spot Development
Why hire dedicated React developers through On The Spot Development
No hidden markups
You see what a React developer costs: the full gross salary and a fixed management fee, as two separate lines on every invoice.
Full operational support
Your React developers 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 frontend team you control
You choose every React developer and set the engineering rules, from component architecture to code review. You see each candidate's stage and recruiter feedback throughout hiring.
Flexible long-term setup
Start with one React developer, then add frontend engineers, QA or a tech lead as the product grows. A buyout right from day one lets you move the team into your own company.
Knowledge stays yours
Each React developer works on your product only and never rotates to other customers. Knowledge of your components, design system and release process builds up in your team.
Cross-functional scaling
Frontend rarely ships alone. On The Spot Development also hires Node.js, Python and .NET backend engineers.
Engagement models
Two ways to hire React developers
Tech recruitment
The React developer is hired directly by your company. We run sourcing and pre-screening for a success fee.
Honest assessment
When hiring React developers 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 roadmap depends on niche senior talent. Senior React developers rarely apply to job posts. Our recruiters contact them directly, including people who aren’t looking for a new job.
Moving off a legacy frontend. Whether it is AngularJS, an outdated version, or a custom UI layer, we have hired engineers for an AngularJS to React migration and screen for that experience.
Your frontend sits next to AI features. We source engineers who understand the backend behind model outputs, streaming responses, and review flows.
One developer will build your frontend team. Start with one senior engineer, then add a tech lead or a design system expert when your product needs it.
Probably Not Yet
Your team can't interview in the next few weeks. Strong React candidates accept other offers while they wait. Plan interview slots before the search starts.
The role description is still changing. New requirements mid-search send the shortlist back to the start. Finalize the tech stack and seniority first, or use our CTO as a service engagement to define them.
You need a fixed-scope project for a fixed price. A project vendor fits this better. Every engineer we hire joins your team for the long run.

FAQ
Hiring React developers: frequently asked questions
How much does it cost to hire a React developer?
On The Spot Development charges the React developer's gross salary plus a fixed management fee, as two lines on the invoice. The salary depends on seniority, the tech stack and availability in the Polish market. The fee covers recruiting, HR, payroll, office and equipment, and doesn't grow as a percentage of salary.
What React roles can I hire through On The Spot Development?
On The Spot Development hires senior React developers, frontend tech leads and design system engineers. We also hire full-stack engineers who pair React with Node.js or Python, and React Native developers for mobile. Every search starts from what the engineer will own in your product.
Can I hire a React developer who also works on the backend?
Yes. Many React roles we fill sit next to a Node.js, Python or Go backend. Orca Security's frontend team works on a React, Node.js, Python and Go stack. Tell us how much backend work the role requires, and we will tailor the sourcing profile and technical interview to match.
Can you hire engineers to migrate a legacy frontend to React?
Yes, we have extensive hiring experience in this area. Engineers we hired for HoneyBook worked on its move from AngularJS to React. The migration runs fully under your technical leadership, and we specifically screen for candidates with deep migration context.
How do you check a React developer's communication skills?
Every candidate is pre-screened in English to check they can explain technical choices to non-technical stakeholders. On The Spot Development shares a recruiter summary before your interview. Your team can also add a design review round to see how they work with product and design.
How long does it take to hire a senior React developer?
Sourcing time depends on seniority, your interview process, and notice periods (up to three months in Poland). You can speed up hiring by locking in the role description and offering weekly interview slots.
What is the difference between a React and a React Native developer?
A React developer builds web interfaces in the browser. A React Native developer uses the same component model to build iOS and Android apps, managing mobile releases, device APIs, and app store reviews. On The Spot Development hires both, including hybrid engineers who work across both technologies.
Who owns the code my React developers write?
You own the code from the moment it's written. Each engineer assigns their work product to On The Spot Development under Polish law. We pass it straight to your company. Every engineer signs a confidentiality agreement before getting access to your systems.
Why hire React developers in Poland?
Poland combines EU contract and IP rules, GDPR by default, and CET working hours that cover the UK working day and the morning on the US East Coast. Senior React salaries sit below US, UK, and Israeli levels. Read more in our guide on how to hire developers in Poland.
Can I move React developers onto my own payroll?
Yes. On The Spot Development gives you a buyout right from day one, not tied to a term or a milestone. The price and the process are set in the contract from the first day, so both sides know the terms before your React developers start.
