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. Qualifications - 5+ years of total software development experience - 3+ years of production experience with React, including complex state management (Redux / Redux Toolkit) - 2+ years of Node.js experience, with hands-on use of Express.js in a production BFF or API layer - Strong proficiency in TypeScript across both frontend and backend - Experience with unit and integration testing (Vitest, Jest, or similar) - 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 - Strong English communication skills (B2+) - Self-organized, proactive, and comfortable working in a distributed team Requirements - Experience with JIRA, and Confluence. - Experience with ElasticSearch - Experience in gambling or online gaming. - Experience with TDD development processes. - Strong interest in applying AI-powered tools (e.g. Claude, ChatGPT, Copilot, Cursor or similar) to speed up day-to-day development tasks. - Proven ability or strong motivation to use AI to reduce development time, improve code quality, and automate repetitive engineering work. Job Responsibilities - New features development within the existing product. - Resolving technical problems as they arise. - Bug fixing of developed features. - Actively leverage AI-assisted tools to improve efficiency across coding, testing, debugging, and other SDLC activities - Writing Unit tests and integration tests. - Communicating with team members and the Product team. - Scrum ceremonies participation. - Mentoring middle and junior colleagues might be required.
