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 Duration: 12 months with potential for extension ## The Role We’re hiring Sr Systems Engineers in Latin America to work at the core of Nexus’s execution stack — contributing to the runtime behind our Layer 1 protocol and the high-performance engine that powers decentralized trading. This is not a typical backend role. You will work on performance-critical systems where microseconds matter, building execution paths that may evolve into core protocol primitives. Your work will directly shape how orders are processed, state transitions are computed, and performance guarantees are achieved across the network. Whether you're a strong mid-level engineer looking to grow into system ownership, or a senior/principal engineer eager to architect high-throughput distributed systems, this role offers the opportunity to build software that runs at the heart of a global execution layer. You’ll collaborate closely with protocol, cryptography, and product teams in San Francisco while contributing remotely from Argentina. ## What You’ll Do - Design and implement high-performance components in Rust, C++, or Go for Nexus’s DEX engine and protocol runtime. - Build low-latency pipelines for order execution, event propagation, and state updates. - Optimize concurrency, scheduling, memory layout, and I/O paths for determinism and throughput. - Contribute to the evolution of execution abstractions that may be enshrined at the protocol layer. - Work with protocol engineers to ensure safety, composability, and consensus compatibility. - Investigate and resolve performance bottlenecks using profiling, tracing, and benchmarking techniques. - Help define standards for reliability, correctness, and high-assurance distributed execution. - For senior/principal candidates: Drive system design decisions, shape execution architecture, and mentor others in performance engineering. ## What We’re Looking For - Strong experience with Rust, C++, Go, or other systems programming languages. - Understanding of high-performance or distributed systems (e.g., low-latency engines, runtimes, databases, OS-level concurrency). - Ability to think in terms of execution flows, concurrency models, resource lifecycles, and system invariants. - Practical experience profiling CPU, memory, and synchronization overhead. - Comfort working close to runtime constraints where performance, determinism, and resilience are critical. - Excellent communication skills in Business English (spoken and written). Levels We're Hiring - Junior 1–3 years - Solid foundations, eagerness to grow, guided ownership - Principal 8+ years - System design leadership, cross-team impact, mentorship, leading 5 Jr engineers in parallel and teams of at least 10 engineers Bonus Points For - Experience building matching engines, databases, compilers, blockchain runtimes, or HPC systems. - Familiarity with lock-free concurrency, zero-copy data structures, or cache-aware design. - Exposure to protocol engineering, consensus systems, or transaction ordering. - Background in correctness-focused engineering (e.g., formal verification, static analysis). - Open-source contributions to systems-level projects. ## Why Join Us - Build the execution backbone of a Layer 1 blockchain and next-generation DEX engine. - Work on systems where your optimizations translate directly into global performance gains. - Grow from mid-level contributor to system owner — or drive execution architecture as a senior/principal. - Shape primitives designed to last — correct, performant, and potentially enshrined at the protocol level. - Join a high-performance engineering culture where ambition and deep technical work are expected. ## About Nexus ## Company Overview - **One-liner**: Nexus is building a purpose-built Layer 1 blockchain for verifiable finance and a global supercomputer for verifiable computation. - **Entity Type**: Private (Series A) - **Headquarters**: San Francisco, California, United States - **Founded**: 2022 (first funding round December 2022) - **Founders**: Daniel Marin (Founder & CEO) ## Core Business - **Primary industry**: Blockchain infrastructure / Verifiable computation / Financial technology - **Target customers**: Developers building financial applications, DeFi protocols, AI workloads, and verifiable computing solutions (B2B / developer ecosystem) - **Mission or purpose statement**: “Purpose-built for Verifiable Finance” and “the supercomputer for everyone, powering the world’s most complex computation to build the Verifiable Internet” ## Products & Services - **Nexus Blockchain (Layer 1)**: A high-performance blockchain designed for intelligent markets and verifiable financial applications. Focuses on speed, verifiability, and composability. - **NexusEVM**: A fully EVM-compatible Layer 1, allowing developers to deploy existing Ethereum tools and smart contracts without modification. - **NEX Token**: The native digital currency of the Nexus blockchain (total supply 100 trillion). Used for network fees, staking, and governance. - **Verifiable Computation Platform**: A global network where users can lend or borrow compute power securely, enabling transparent and accountable software. ## Market Standing - **Valuation/Market Cap**: Not disclosed - **Key Metric**: Total funding – $27.2 million (as of June 2024) - **Notable Investors/Partners**: - Lightspeed Venture Partners (lead, Series A) - Pantera Capital (co-lead, Series A) - Dragonfly (lead, Seed round) - **Growth Signals**: - Headcount growth of +248.1% year-over-year (LinkedIn reports 55 employees as of mid-2025; a conflicting report from BuiltIn lists 32 employees – likely older data) - Mainnet launched in 2025 - Introduced NEX token and NexusEVM - Expanding globally with employees in 16 countries (including India, Argentina, Nigeria, Indonesia, France) ## Competitive Advantages - **Purpose-built for finance**: Unlike general-purpose blockchains, Nexus is optimized for high-performance financial applications and intelligent markets. - **Verifiable computation focus**: Backed by leading researchers (e.g., Chief Scientist Jens Groth) and a team with deep expertise in zero-knowledge proofs and cryptography. - **EVM compatibility**: Lowers the barrier for Ethereum developers to migrate or build on Nexus. - **Strong investor backing**: Led by top-tier crypto and fintech VCs (Lightspeed, Pantera, Dragonfly). ## Strategic Focus - Scaling the Nexus ecosystem and attracting developers to build on the Layer 1. - Expanding verifiable computation use cases into AI, agentic finance, and enterprise applications. - Growing the NEX token utility and liquidity. - Building a global, remote-first engineering team (current job openings target LATAM contractors for engineering roles). ## Why Work Here - **Mission-driven culture**: Employees describe joining “for the mission and staying for the momentum” – solving ambitious problems in verifiable computation. - **Fast-paced, strategic environment**: The company is in constant motion, with a focus on shipping and innovation. - **Remote-friendly**: The majority of roles are remote, with a physical office in San Francisco. Current open positions (Head of Engineering, Backend Engineer, Infrastructure Engineer) are contract-based in LATAM. - **Diverse, global team**: Employees from 16 countries, spanning engineering, science, marketing, and operations. - **Perks**: Not detailed publicly, but the company emphasizes a supportive, high-impact environment with brilliant colleagues. ## Sources 1.
