• Collaborate with Product teams to deliver features such as in-chat tipping, reactions, and unlockable content.
• Work with SRE to define infrastructure, monitoring, and scaling strategies for peak usage.
• Act as a technical leader by improving engineering practices and mentoring other engineers.

Requirements

 • Strong experience in backend or distributed systems engineering, including real-time service development (WebSockets, gRPC, streaming architectures).
• Proven ability to design scalable, fault-tolerant systems from first principles.
• Solid product-minded engineering instincts with understanding of monetisation and user value.
• High ownership mentality with a pragmatic, outcome-driven approach.
• Experience debugging complex performance issues using tools like Prometheus, Grafana, or DataDog.
• Mastery of backend languages such as Go, Node.js, or C# and experience with REST and event-driven APIs.
• Excellent communication skills for articulating technical trade-offs and solutions.
• Familiarity with NoSQL or in-memory data stores (e.g., Redis, DynamoDB) is a plus.
• Experience in creator platforms, chat products, or AI-enabled systems is advantageous.
• Prior experience building monetisation primitives or transactional messaging features is desirable.

Benefits
