Nexus is innovating at the intersection of artificial intelligence, blockchain, and zero-knowledge cryptography to build a Layer 1 for the AI era. The company is seeking to design and scale the core infrastructure powering its Layer 1 blockchain and a high-performance DEX enshrined in the L1 protocol, requiring deep expertise in low-latency distributed systems and the ability to deliver secure, production-grade infrastructure for financial applications.
Requirements
- 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.
- 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.
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.
Other
- Remote in New York
- 6–10+ years in software engineering, with at least 3+ years in infrastructure or systems roles.
- Meaningful ownership in the Nexus protocol
- Health insurance for employees and their dependents
- 401(k)
