Infrastructure Engineer (Contract – LATAM)

About the role

Nexus is the engine for verifiable finance — a blockchain designed to natively embed the world’s financial system into one compounding system. Built to support every major financial market on a single global exchange, Nexus unifies infrastructure that has historically been fragmented across chains and intermediaries. Headquartered in San Francisco with a growing presence in Buenos Aires, Nexus is proud to be a cross-continental team of engineers, cryptographers, and market builders. We’re investing deeply in the Latin American ecosystem — and always looking for world-class talent to join us.

What You'll Do

• Support the deployment and maintenance of distributed infrastructure powering Nexus's L1 blockchain and exchange.
• 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.

Must-Have Experience

• 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.
• 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 practices.

Bonus Points

• Eagerness to learn secure, fault-tolerant infrastructure practices.
• Good written and spoken Business English.
