nexus.xyz - Infrastructure Engineer (Contract – LATAM)
Requirements
• Experience running distributed blockchain infrastructure, validator networks, or Layer-1 systems. • Knowledge of MEV mitigation, transaction ordering fairness, or decentralized exchange infrastructure. • Experience optimizing consensus or transaction pipelines for determinism and low latency. • Familiarity with zero-knowledge proofs or cryptographic
Responsibilities
• Support the deployment and maintenance of distributed infrastructure powering Nexus's L1 blockchain and DEX. • Assist in optimizing transaction pipelines for speed and reliability under senior guidance. • Contribute to building secure, production-grade systems that meet performance requirements. • Help maintain high-availability infrastructure across cloud and distributed environments. • Learn and apply best practices for observability, reliability, and secure operations. • What Success Looks Like • Reliable contribution to a stable mainnet with consistent uptime and availability. • Active participation in improving DEX performance and latency. • Quickly ramping up on internal tooling and workflows — first meaningful contribution within the first month. • Growing comfort with high-performance benchmarking and infrastructure tuning. • Positive collaboration with the team and consistent delivery on assigned tasks. • 1–3 years of software engineering experience, with some exposure to infrastructure or distributed systems. • Working knowledge of Rust, Go, or another systems language. • Basic understanding of distributed systems concepts (consensus, fault tolerance, latency). • Hands-on experience with Docker; familiarity with Kubernetes is a plus. • Exposure to observability tools such as Prometheus, Grafana, or similar. • Familiarity with Infrastructure-as-Code tools such as Terraform or Pulumi. • Basic experience with at least one major cloud provider (AWS, GCP, or Azure). • Eagerness to learn secure, fault-tolerant infrastructure practices. • Good written and spoken Business English.
Benefits
• Build the distributed infrastructure behind a next-generation Layer 1 blockchain. • Work on systems where infrastructure performance directly shapes the end-to-end trading experience. • Collaborate with top engineers in AI, cryptography, runtime systems, and distributed consensus. • Shape primitives and infrastructure designed for long-term correctness, performance, and global scale. • Join a high-performance engineering culture where deep technical work is valued and expected.
