[Hiring] Senior Infrastructure Engineer @Nexus.xyz

Role Description

We’re hiring a Senior Infrastructure Engineer in Latin America to design and scale the core infrastructure supporting Nexus’s Layer 1 blockchain and its high-performance DEX, enshrined at the protocol layer.

• Architect and implement the distributed infrastructure powering Nexus’s L1 blockchain and high-performance DEX.
• Optimize consensus and transaction pipelines for speed, determinism, fairness, and low latency.
• Build secure, production-grade systems that meet the performance requirements of modern financial exchanges.
• Develop and maintain high-availability, fault-tolerant infrastructure across cloud and distributed environments.
• Offer best practices for reliability, observability, performance engineering, and secure operations.

Qualifications

• 6–10+ years of software engineering experience, with at least 3+ years in infrastructure or distributed systems roles.
• Strong programming experience in Rust (preferred), Go, or another systems language.
• Deep expertise in low-latency, high-throughput, or distributed systems (HFT, exchanges, runtimes, consensus systems, etc.).
• Hands-on experience with container orchestration systems such as Kubernetes and Docker.
• Experience building and maintaining observability systems, including metrics, tracing, and logging frameworks (e.g., Prometheus, Grafana, OpenTelemetry).
• Proficiency with Infrastructure-as-Code tools such as Terraform, Pulumi, or CloudFormation.
• Deep knowledge of at least one major cloud provider (AWS, GCP, or Azure), including networking, compute, security, and distributed workloads.
• Ability to design and operate secure, fault-tolerant, production-grade infrastructure.
• Excellent written and spoken Business English.

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 techniques.

Benefits

• Build the distributed infrastructure behind a next-generation Layer 1 blockchain and global DEX.
• 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.
