13 hours ago

Prague, Hlavní město Praha, Czech Republic Tatum Full time 1,200,000 - 2,400,000 per year
It's not a job. It's a calling.

Are you ready to build something that handles millions of requests per second, processes terabytes of data, and powers the future of blockchain infrastructure?

At Tatum, we're not just a leading blockchain development platform – we're the foundation behind over 100,000 Web3 projects and enterprises. Backed by a recent $41.5M funding round, we are entering a new era of global scale and performance – and we need builders like you to help us push the limits.

Why this role?

We're looking for a Backend Engineer who thrives in low-latency, high-throughput environments. Your primary language might be C, C++, Rust, or Java – we care more about your mastery of performance-critical backend systems, your ability to squeeze microseconds out of the stack, and your deep understanding of networking, distributed systems, and real-time architectures.

This is your opportunity to step into a team where technical challenges aren't just welcome – they're the job.

What you'll build

You'll help evolve the core of our flagship blockchain connectivity layer – the engine that lets developers interact with a multitude of blockchain networks seamlessly. Expect to:

  • Design and build scalable, high-performance backend services.
  • Technology stack: modern Java, Eclipse Vert.x, Redis, Kafka, Grafana.
  • Engineer systems that process millions of API calls and terabytes of data with resilience and speed.
  • Optimize system performance from the network layer up to the application layer.
  • Collaborate across product, and infrastructure teams to bring groundbreaking blockchain services to life.
What you bring
  • Strong experience with backend development, for example in C, C++, Rust, or Java.
  • Deep understanding of networking, multithreading, memory management, and low-latency system design.
  • Proven track record of working on high-performance, large-scale backend systems.
  • Familiarity with containerization, cloud-native environments, observability and modern CI/CD pipelines.
  • Bonus: Experience with blockchain technology, cryptographic protocols, or Web3 ecosystems.
Why join Tatum?
  • We're solving real, large-scale problems for the next generation of internet infrastructure.
  • You'll be part of a fast-moving, elite engineering team with global impact.
  • Competitive compensation, equity options, and global reach.

This isn't just a job – it's a launchpad for your next great challenge.

Are you ready?
