Backend Engineering Team Lead

As a Team Lead – Wallet at Betsson Group, you will lead a team of talented engineers responsible for one of the most critical platforms in our ecosystem – the system that securely handles player balances and financial transactions across our global gaming operations. 

Wallet platform is one of Betsson’s most critical systems, responsible for maintaining player balances and processing high volumes of real-time financial transactions across multiple regulated markets with strict requirements on correctness, reliability, and consistency. 

As a Team Lead, you will play a key role in both technical leadership and people leadership, working hands-on with your team to design, build and evolve one of Betsson’s core platforms.

• Reliability and consistency 

• Performance and scalability under high transaction load 

• Operational stability 

• Cost-efficient cloud operation 

Wallet is a transaction-heavy system with a strong relational database core, and engineers are expected to have strong understanding of backend architecture, data consistency, and performance considerations. 

You will collaborate closely with Product Managers, Architects, DBAs, and DevOps teams to ensure the platform evolves to meet both business and regulatory needs across multiple jurisdictions.
