Nexus has raised $25M in Series A funding from Lightspeed, Pantera, Dragonfly, SV Angel, and more.
Role Overview
Remote in New York or hybrid in San Francisco
Nexus is seeking a Senior Infrastructure Software Engineer — with the potential to grow into a Tech Lead — to design and scale the core infrastructure powering our Layer 1 blockchain and its first core application: a high-performance DEX enshrined in the L1 protocol.
This role requires deep expertise in low-latency distributed systems and the ability to deliver secure, production-grade infrastructure for financial applications. You’ll work closely with Product, Research, and Security to build a system that meets the performance, reliability, and fairness requirements of modern trading systems — in a decentralized context.
Responsibilities
Architect and implement low-latency, high-throughput financial infrastructure for Nexus’s Layer 1 and DEX.
Own major roadmap milestones: public testnet → mainnet → institutional-grade performance.
Optimize consensus and transaction pipelines for speed, determinism, and security.
Collaborate with cryptography and protocol teams to integrate cutting-edge zero-knowledge proofs into production systems.
Mentor mid-level engineers and establish engineering best practices for reliability, security, and observability.
Ensure high availability and fault tolerance for mission-critical financial systems.
What Success Looks Like
Mainnet launch with enterprise-grade reliability and sub-second transaction finality.
DEX achieves low-latency trade execution comparable to centralized systems while maintaining decentralization.
Engineering systems and tooling enable <10 min developer onboarding to first transaction.
High-frequency trading performance benchmarks met or exceeded.
Engineering team scaled while maintaining high velocity and code quality.
Requirements
6–10+ years in software engineering, with at least 3+ years in infrastructure or systems roles.
Expertise in low-latency, high-throughput systems (e.g., HFT, distributed trading platforms, real-time financial exchanges).
Strong programming background in Rust (preferred), C++, Go, or similar systems languages.
Deep knowledge of network protocols, concurrency, and distributed systems.
Experience delivering secure, production-grade systems with measurable performance gains.
Bonus Points:
Previous experience in DeFi infrastructure, Layer 1 blockchains, or consensus protocols.
Familiarity with MEV prevention, transaction ordering, or fairness protocols.
Exposure to cryptography, zero-knowledge proofs, or formal verification.
Benefits
Competitive salary
Meaningful ownership in the Nexus protocol
Health insurance for employees and their dependents.
