About Nexus
Nexus is building the foundation for verifiable finance, an economic system where every transaction, order, and settlement can be proven on-chain with cryptographic assurance. To do this we’re developing a DEX Layer 1 blockchain purpose-built for the AI economy, powered by idle compute from millions of people around the world, and verified with zero-knowledge proofs. This is finance rebuilt for the future: verifiable, scalable, and open to all.
Nexus has raised $25M in Series A funding from Lightspeed, Pantera, Dragonfly, SV Angel, and more.
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.
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.
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.
A 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.
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.
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
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.
