5d • Remote

About The Position

Nexus is seeking a Junior/Mid Infrastructure Engineer in Latin America to support and help build the core infrastructure powering Nexus's Layer 1 blockchain and its high-performance DEX. This role focuses on distributed infrastructure supporting financial workloads that demand reliability and performance. The engineer will work closely with senior engineers, product, and protocol teams while contributing remotely from Argentina or broader LATAM. This is an opportunity to grow your career working on infrastructure at the heart of a global execution system — from public testnet through mainnet.

Requirements

• 2–4 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.

Nice To Haves

• 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.

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.
