Why On The Spot Development
Why hire dedicated .NET developers through On The Spot Development
No hidden markups
You see what a .NET developer costs: the full gross salary and a fixed management fee, as two separate lines on every invoice.
Full operational support
Your .NET 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 backend team you control
You choose every .NET developer and set the engineering rules, from service architecture to code review. You see each candidate's stage and recruiter feedback throughout hiring.
Flexible long-term setup
Start with one senior .NET engineer, then add backend developers, QA or a team lead as the product grows. A buyout right from day one lets you move the team into your own company.
Knowledge stays yours
Each .NET developer works on your product only and never moves to other customers. Knowledge of your services, data model and release process builds up in your team.
Several openings, one search
Need three or four .NET engineers at once? We run one search for all openings and send candidates in parallel, so the team doesn’t grow one hire at a time.
Engagement models
Two ways to hire .NET developers
Tech recruitment
The .NET developer is hired directly by your company. We run sourcing and pre-screening for a success fee.
Honest assessment
When hiring .NET 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
A senior .NET role has stalled. Senior .NET engineers rarely apply to job posts. Our recruiters contact them directly, including people who aren't looking for a new job.
Your .NET engineers also work on infrastructure. We hire C# engineers who work with Terraform, Docker, Kubernetes and CI/CD, so one hire covers the service and its pipeline.
You keep hiring at home too. Add .NET engineers in Poland while your home team grows. We use your seniority levels and interview process, so both teams are hired to the same standard.
Probably Not Yet
Your team can't interview in the next few weeks. Strong senior .NET candidates get other offers while they wait. Plan interview slots before the search starts.
If the role description is still changing. A must-have added mid-search, such as Angular next to .NET, sends the shortlist back to the start. Finalize the tech stack first, or use our CTO as a service engagement to define it.
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 .NET developers: frequently asked questions
How much does it cost to hire a .NET developer?
On The Spot Development charges the .NET 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 .NET roles can I hire through On The Spot Development?
On The Spot Development hires .NET developers from junior to senior level, plus team leads. We also hire C# backend engineers who work on infrastructure, and full-stack engineers who pair .NET with Angular or React. Every search starts from what the engineer will own in your product.
Can you hire backend engineers who switch to .NET?
Yes, if your team agrees. For hard-to-fill .NET roles, we also look at backend engineers from Java, Go or Python with microservices experience who want to move to C#. With AI coding assistants, the language is the fast part to learn. You decide in the brief whether the role needs years of .NET or strong backend fundamentals.
Do .NET developers have to work from Warsaw?
No. Engineers work from our Warsaw office in a hybrid format or remotely from elsewhere in Poland, agreed per role before the search starts. For senior .NET roles, a hybrid Warsaw requirement narrows the pool noticeably. If your team works with remote engineers, we search across Poland.
How long does it take to hire a senior .NET developer?
Time depends on seniority, your interview rounds and the notice period, which can be up to three months in Poland. Weekly interview slots and a stable role description shorten it.
Who manages the developers day to day?
Your team does. Developers work in your processes, sprints and code review, and report to your managers. On The Spot Development runs the employment side: payroll, HR, office and equipment, with an account manager as your contact point.
What is the difference between a C# developer and a .NET developer?
C# is the language. .NET is the platform around it: the runtime, ASP.NET Core for web services, Entity Framework for data access and the libraries in between. Most job titles use the terms interchangeably. On The Spot Development screens for both, plus the parts of the platform your product uses.
Who owns the code my .NET 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 as it's created. Your contract passes it straight to your company. Every engineer signs a confidentiality agreement before getting access to your systems.
Can I move .NET 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 .NET developers start.
Why hire .NET developers in Poland?
Poland combines EU contract and IP rules, GDPR by default and CET working hours that cover the UK day and the New York morning. Senior .NET salaries sit below US, UK and Israeli levels. Read more in our guide on how to hire developers in Poland.
