[Hiring] Senior Fullstack Developer @Symphony Solutions

Role Description

As a Fullstack Developer on our team, you will own end-to-end delivery of the BetSymphony Backoffice and frontend applications — a mission-critical internal tool used by operators to manage players, trading, promotions, casino, payments, and reporting in a regulated environment where correctness, performance, and reliability are non-negotiable.

We are a team that embraces AI-assisted development as a standard part of the engineering workflow. We expect our engineers to actively use AI tools to accelerate delivery, improve code quality, and reduce time spent on repetitive work — not as an experiment, but as an everyday practice.

• Experience working in a microservices architecture, including understanding of BFF layer integration
• Familiarity with Docker and basic Kubernetes workflows
• Proven experience using AI-assisted development tools (e.g., Claude, Cursor, GitHub Copilot, ChatGPT) in daily work (code generation, refactoring, debugging, testing, documentation) — this is a standard expectation, not optional
