Senior Backend Engineer (Java)

Department: R&D Location: Limassol Employment type: Full-time Experience: Senior

Description

Tango is a global live-streaming platform operating at real scale: 500M+ registered users. We build the backend systems behind live video, creator monetization, recommendations, moderation, payments, and AI-powered user experiences.

This is not a typical CRUD backend role. You will work on distributed systems powering a real-time consumer product with demanding requirements for scale, latency, resilience, and cost efficiency. Parts of the platform operate at up to 50k RPS, and the engineering challenges span backend architecture, reliability, automation, and product impact.

We invest heavily in AI across both product and engineering. We are building an engineering culture where engineers own quality, automation is increasingly AI-assisted, and manual bottlenecks are continuously reduced.

Responsibilities

• Design, build, and evolve high-performance backend services for core product flows
• Own services end-to-end: architecture, implementation, testing, rollout, observability, and production reliability
• Solve distributed systems challenges related to scalability, latency, resilience, and cost efficiency
• Contribute to high-load systems, including components operating at up to 50k RPS
• Drive architectural decisions and improve reliability, performance, and operational simplicity
• Work closely with product, infrastructure, platform, and data teams to deliver measurable business impact

Requirements

• Strong computer science fundamentals: algorithms, data structures, concurrency, and performance
