Job description

About us

An online casino powered by the SoftSwiss platform. The front-end is React-based and integrated with the SoftSwiss game aggregator, cashier module, and player registration. After a redesign, we need skilled developers to take over the project, stabilize it, and later contribute to additional web projects.

We are hiring two part-time/full-time engineers so the system is never dependent on a single person. Both will be cross-trained on the casino platform.

What you’ll do

• Take ownership of the existing React site.
• Audit the codebase, APIs, and deployment.
• Fix critical issues in registration, cashier, and game launch flows.
• Improve security, testing, and monitoring.
• Deliver technical documentation and handover materials.
• Participate in other ongoing projects after the takeover phase.

Tech stack & integrations

• Frontend: React (TypeScript)
• Backend: Node.js / Express (Nest.js a plus)
• APIs: SoftSwiss Game Aggregator, Cashier module, Registration/Auth
• DB: PostgreSQL (other SQL is fine)
• Infra: Docker, CI/CD pipelines, cloud hosting
• iGaming integration experience is a plus

Requirements

• 3+ years as a full-stack developer.
• Strong React + TypeScript skills.
• Solid Node.js backend experience.
• Hands-on experience with third-party API integrations (payments, fintech, iGaming a big plus).
• Good understanding of authentication, sessions, and secure coding practices.
• Independent and reliable: able to audit, fix, and deliver without supervision.
• English: Upper-Intermediate (enough for tech documentation and communication).

We offer

• Remote work on European time zone.
• Competitive salary.
• Dynamic environment.
• Contractor (B2B/freelance) or long-term agreement.
• Initial project: stabilize & document the casino site.
• Ongoing work: participation in new web projects.

How to apply

Submit the following:

• A short intro with relevant experience.
• Links to projects, GitHub, or portfolio (iGaming/fintech/payments experience is a big plus).
• Availability (part-time / hours per week).
