Senior Back-end Developer

We are looking for a Senior Back-end Developer to develop custom wallet adapters, ensure transaction integrity, and build data pipelines in iGaming.

What you'll do

• Develop custom wallet adapters (seamless API) for direct operators, aggregators, and white-label cases not covered by standard integration.
• Ensure transaction integrity: idempotency, correct cancel flow, HMAC authorization, protection against double debits.
• Configure and launch standard integrations with aggregators via Back Office, run Wallet Verifier and smoke tests.
• Build a custom service layer on top of RGS: capture transaction events, calculate product metrics (GGR/NGR, actual RTP, APPC, retention), create data marts and dashboards.
• Build a data pipeline for these metrics: event → storage → reporting.

What we need

• Commercial experience of 4+ years in Back-end development
• Experience in iGaming: understanding of seamless wallet, provider-operator model, idempotency of financial transactions and cancel/rollback logic
• Technical skills: TypeScript, REST, working with databases, queues/event streaming, Docker, Git
• Attention to transaction integrity and error handling in distributed systems, experience building analytical data marts

What's in it for you

• Startup-driven atmosphere: work in a fast-growing studio where your contribution is visible from day one, no rigid bureaucracy
• Accelerated career growth: transparent and fast track for career development and internal promotion opportunities
• High level of autonomy: freedom to take initiative, full ownership of tasks, and significant creative responsibility
