About the Team

Wix’s Server Engineering team where lead developers shape the architecture of our backend microservices. They set the tone and standard of our developer culture, fusing facets of engineering, product management, DevOps, analytics, and technical management.

The Wix development culture is transparent, highly technical, and agile. Because we ship often, we’ve happily adopted Continuous Delivery and Test-Driven Development. Our primary technologies on server side are JVM (mostly in Scala) and Node JS. We develop and maintain highly scalable systems that support Wix’s tens of millions of users—and the people who visit their websites. We strive to hire engineers who have ‘fire and forget’ abilities, and who are independent, innovative, and bold.

Profitable 10+ year iGaming group. Real products, real users, real money.
B2B platform + in-house PSP & crypto wallet. No “startup chaos”, but also no corporate boredom.

Your first challenges:

1️⃣ Operators vs Platform — who is right?
Where B2C customization ends and B2B responsibility begins — and create rules so this fight stops happening weekly.

2️⃣ Segments, bonuses & CRM logic
High rollers, bonus hunters, casuals — all want different treatment.
You redesign platform capabilities so CRM can run segmentation strategies without dev team crying every sprint.

3️⃣ Scale vs Reality (CPO 🤝 CTO negotiations)
Growth says: “we launch 3 new markets.”
CTO says: “platform dies.”
You turn this into a roadmap both sides sign — architecture, priorities, and business impact aligned.
 

What you will own:

• Group product strategy (B2B igaming platform)
• Growth, retention & monetization economics
• International scaling & launches
• Product org across Product, Dev, Design, Growth

Turning CEO vision into execution 
 

You probably are:

• CPO / Head of Product / COO / CEO in iGaming (must)
• Fintech experience 
• Strong in lifecycle, LTV, retention & scaling

Strategic brain + hands-on operator
 

Why it’s interesting:

• Direct CEO partnership (no bureaucracy simulator)
• Mature profitable business (no “runway 3 months” drama)

Real authority — you decide, you ship, you own
 

Package:

• $10k–$15k/month + performance bonus
• 18 vacation + 25 sick days
• Health coverage + learning budget
• Remote / Hybrid / Office (Ukraine, Cyprus, Armenia)

Important: NOT ready to review candidates without B2B iGaming experience! 
 

If you like complex systems, business impact and healthy arguments with engineers — you’ll enjoy this.
