Turn your tech skills into industry changing solutions

Put your career growth on the fast track

Ever dreamed of building something from scratch that impacts millions? That's our daily reality at OPP. While others are busy piecing together third-party solutions, we've built our entire payment platform in-house. Yes, every single line of code. When you push changes here, they impact how millions of Europeans pay online through major marketplaces.

Owning every line of code means your career can scale faster than you can say "deployment." Here, you'll work alongside the original architects who built this system 15 years ago, helping create the future of marketplace payments. If you're ready to build in-house solutions that impact millions and supercharge your career along the way, discover your next oppurtunity at OPP and apply now.

Why you will like us

Good to know

Cross-Category Platform Support

Cross-Category
Platform Support

Right now, we're the go-to solution for specialized marketplaces - think hobby supplies, crowdfunding, or second-hand goods. But we're thinking bigger. We're engineering our platform to support multi-category marketplaces like Shopify, where merchants sell everything from artisanal coffee to vintage vinyl.

It sounds simple, but trust us - making our platform this flexible while maintaining our legendary reliability is the kind of challenge that keeps our developers up at night (in a good way).

In Person Payments

In Person Payments
(POS mobile)

While we've mastered online marketplace payments, we're not stopping there. Picture this: your phone becomes the payment terminal. No bulky card machines needed - just tap and pay.

We're building a mobile POS system that will let marketplace platforms extend their reach into the physical world with nothing more than a smartphone. Simple for users, complex for us to build - exactly the kind of challenge we love.

Our commitment to your growth

Together with your dedicated talent manager, you'll map out your journey to becoming an online payment pioneer - whether that's mastering distributed systems, becoming a security protocol guru, or architecting flawless APIs. You get the freedom to dive deep, while we provide the roadmap and resources to help you rise. The result? You'll be simplifying payments for millions while supercharging your career.
