Senior Software Engineer (Blockchain Load Balancer Development) - European Time Zone

Job Description: Senior Software Engineer (Blockchain Load Balancer Development)

Responsibilities:

• Design and Develop Blockchain Load Balancers: Architect, build, and optimize load-balancing systems for blockchain nodes to ensure fault tolerance, low latency, and efficient traffic distribution.
• Manage Scalable Infrastructure: Deploy and maintain Kubernetes clusters and Linux-based systems to support secure, high-availability blockchain node operations.
• Testing and Optimization: Conduct performance, stress, and security testing on load balancers, ensuring resilience during node failures or traffic spikes.
• Data-Driven Monitoring: Implement monitoring and analytics solutions using tools like ClickHouse to track node performance, traffic patterns, and system health.
• Cross-Functional Collaboration: Partner with DevOps, blockchain, and data engineering teams to integrate load balancers with broader infrastructure and analytics pipelines.

What You’ll Bring:

• Experience: 5+ years in software engineering, with expertise in distributed systems, infrastructure, and blockchain technologies.
• Technical Expertise:
  • Proficiency in Go (mandatory), with a focus on blockchain or high-performance systems.
  • Strong understanding of EVM-based blockchain architectures and node communication (RPC/HTTP/WebSockets).
  • Hands-on experience with load-balancing algorithms (e.g., round-robin, weighted, least connections) and tools (e.g., Envoy, HAProxy).
  • Familiarity with Kubernetes, Linux, and cloud platforms (AWS, GCP, Azure).
  • Experience with ClickHouse for large-scale data storage, analytics, or monitoring.
• Analytical Skills: Ability to diagnose performance bottlenecks, debug latency issues, and optimize distributed systems.

Preferred Qualifications:

• Bachelor’s/Master’s in Computer Science, Engineering, or a related field.
• Experience with blockchain platforms like Ethereum or layer-2 solutions (e.g., Optimism, Arbitrum).
• Contributions to open-source infrastructure projects or blockchain tooling.
• Knowledge of data engineering tools (e.g., Prometheus, Grafana) and security best practices (TLS, rate limiting).
