Infrastructure Engineer (Contract – LATAM)
About Nexus
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.
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.
Location: Remote
Type: Contract
The Role
We're hiring different levels of Infrastructure Engineer in Latin America to support and help build the core infrastructure powering Nexus's Layer 1 blockchain and its high-performance exchange, enshrined at the protocol layer.
This role focuses on distributed infrastructure supporting financial workloads that demand reliability and performance. You'll work closely with senior engineers, product, and protocol teams while contributing remotely from Argentina or broader LATAM.
This is a great opportunity to grow your career working on infrastructure at the heart of a global execution system — from public testnet through mainnet.
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.
What Success Looks Like
Reliable contribution to a stable mainnet with consistent uptime and availability.
Active participation in improving exchange performance and latency.
Quickly ramping up on internal tooling and workflows — first meaningful contribution within the first month.
Growing comfort with high-performance benchmarking and infrastructure tuning.
Positive collaboration with the team and consistent delivery on assigned tasks.
Must-Have
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.
Levels we're hiring
Junior 1–3 years - Solid foundations, eagerness to grow, guided ownership
Senior 5+ years - System design leadership, cross-team impact, mentorship
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 cryptographic
Why Join Us
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.

The Role
We are looking for a Head of Engineering to own the technical architecture across Nexus’s product surface and ensure the code shipped by our engineering pods is coherent, performant, and built to last. You’ll set the bar for how we design systems, write code, and review each other’s work — and you’ll do it with your hands on the keyboard, not just on a whiteboard.
You’ll partner closely with engineering management to grow pod maturity, raise the level of technical decision-making across the team, and turn architectural intent into shipped product. This is a senior individual-contributor role with broad influence — ideal for someone who has been a staff/principal engineer or hands-on tech lead and wants the autonomy and leverage of a small, ambitious team.
What you’ll do
Own the architecture. Define and evolve the technical architecture spanning our Rust services, Go infrastructure, and Next.js/TypeScript surfaces on GCP — and make sure what gets built actually matches it.
Stay hands-on. Write production code in the highest-leverage parts of the stack: critical services, shared libraries, complex integrations, and load-bearing changes that set patterns for the rest of the team.
Guide pods of engineers. Work across multiple pods to align on system boundaries, interfaces, data models, and non-functional requirements. Lead design reviews and unblock teams on hard technical decisions.
Raise the engineering bar. Shape how we do code review, testing, observability, on-call, and incident response. Drive the practices that make a team able to ship quickly and safely at scale.
Cultivate engineering maturity. Partner with engineering managers to grow ICs, mentor tech leads, calibrate seniority, and develop the next generation of architects on the team.
Translate strategy into systems. Work with product, research, and leadership to turn ambiguous goals into clear technical plans and sequenced execution paths.
Communicate clearly. Write crisp design docs, RFCs, and post-mortems. Make complex systems understandable to engineers, leadership, and partners.
What we’re looking for
Experience. 8+ years building production software, including 2+ years in an engineering leadership capacity — tech lead, staff engineer, or architect responsible for system-level design across multiple teams.
Tech stack fluency. Deep, hands-on proficiency in our core stack that can be Rust, Go, Next.js / TypeScript or Node, and Google Cloud (GCE/GCP). You’ve shipped non-trivial production systems in these technologies, not just read about them.
High-throughput, low-latency systems. You’ve designed and operated production systems where throughput and tail latency are first-class constraints — think trading systems, real-time matching/order flow, high-frequency event pipelines, or comparable performance-critical infrastructure.
Architecture chops. Demonstrated track record designing distributed, performance-sensitive systems and making sound trade-offs around correctness, latency, throughput, and operability.
Engineering judgment. Strong instincts for code quality, testing strategy, and sustainable abstractions. You know when to invest, when to ship, and when to pay down debt.
Leadership without authority. You influence through clear thinking, written artifacts, and credible code — not titles. You’ve mentored senior engineers and helped grow tech leads.
Communication. Fluent written and spoken English. You can run a design review with senior engineers and explain a system to a non-technical stakeholder in the same day.
Remote-readiness. Based in Latin America, comfortable working asynchronously, and able to maintain meaningful overlap with US Pacific working hours.
AI-native. Embrace AI as a core part of how you work, think, and build.
Bonus points
Open-source contributions in Rust, Go, or the broader systems ecosystem.
Experience with Web3 exchanges
Experience standing up engineering practices (CI/CD, observability, on-call) inside a fast-growing org.
Prior work as a founding or early engineer at a high-velocity startup.
Prior experience managing or otherwise leading high-performing teams
Our stack
Backend & systems: Rust, Go
Web & product surfaces: Next.js, TypeScript
Infrastructure: Google Cloud (GCE/GCP), containerized services, modern CI/CD
