For freelancers
Freelance engineer? Get offers that fit your stack.
Apply once. When a client needs someone like you, we send you an offer and you decide. Work under SDK's contract and get paid through the portal, or join the client directly.
What you get from the network
Offers that fit
We only send you work where your stack and experience are the reason you are there.
You decide every time
Each offer tells you what the work is, the skills, the start date and how long. Answer “I'm interested” or “Not now”.
Less admin
When you work under SDK's contract, we handle the paperwork with the client and pay you through the portal.
One place for everything
Your profile, your offers, your current work and your payments, all in your SDK portal account.
Who we are looking for

FAQ
Do I become an employee?
No. You stay freelance. When a client picks you, you either work under a contract with SDK Enterprises or the client hires you directly.
What happens after I apply?
Someone at SDK reviews your application: your work history, your CV and your technical fit. We email you with the outcome. If something is missing, we ask you for changes first.
Do I have to accept every offer?
No. Answer “Not now” whenever an offer does not suit you. We only share your profile with a client after you say you are interested.
How do I get paid?
When you work under SDK's contract, you connect your payout account once in the portal, then see every payment there. If a client hires you directly, you arrange payment with them.
Does joining guarantee me work?
No. We send offers when a client need fits your stack and experience, so how often you hear from us depends on the work we have. We would rather be clear about that from the start.
Do I need to be based in France?
No, but for now you need to be based in the EU, the EEA, the United Kingdom or Switzerland. We work with European and remote clients, in French or English. Location needs depend on each client.
Can my studio join?
Yes, if you are up to 10 people. The studio's lead creates the studio and invites the team. Each person applies and is reviewed individually, and SDK pays the studio for its members' work.
