Requirements:

  • Strong backend engineering experience in Python, C++, or Java
  • Proven track record building scalable, distributed systems
  • Solid understanding of event-driven architecture and asynchronous systems
  • Experience with messaging systems (Kafka, RabbitMQ, etc.)
  • Interest in crypto, blockchain, or decentralised technologies
  • Motivation to learn and work with Rust

Nice to have:

  • Experience working in crypto, fintech, or high-frequency systems
  • Exposure to blockchain protocols, wallets, or node infrastructure
  • Experience with Rust or other systems-level languages
  • Familiarity with cloud-native environments (AWS, GCP, Kubernetes)
What we offer:
