About NexusNexus 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.Nexus is backed by leading investors, including Pantera, Lightspeed, Dragonfly, Faction, Blockchain Builders Fund, Alliance, and SVA, and works with more than 100 partners across the global finance and blockchain stack.The RoleWe’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.This role is centered on low-latency, high-throughput distributed infrastructure, supporting mission-critical financial workloads that demand determinism, fairness, and resilience. You’ll collaborate closely with product, protocol, and cryptography teams while contributing remotely from Argentina or broader LATAM.This position offers the opportunity to work on infrastructure that sits at the heart of a global execution system — ensuring reliability from public testnet through mainnet and institutional-grade performance.What You’ll DoArchitect 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.What Success Looks LikeA stable, enterprise-grade mainnet with high availability and sub-second transaction finality.A DEX achieving low-latency execution comparable to centralized trading systems while remaining decentralized.Infrastructure, tooling, and developer workflows enabling less than 10 minutes from onboarding to first transaction.High-frequency trading benchmarks met or exceeded.An engineering environment that scales effectively without compromising reliability or code quality.What We’re Looking ForMust-Have6–10+ 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.Bonus Points: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 cryptographicWhy Join UsBuild 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.
