Description

This is a remote position. The company aims to make blockchain technology more accessible by reducing complexity for users and developers, and to build a decentralized future where financial systems are open, transparent, and accessible to everyone. They operate within the NEAR intent protocol ecosystem and have built a framework for intent-based, automated crypto transactions that enables automated, cross-chain, and AI-driven financial transactions. They have created secure, decentralized liquidity layers via their Cross-Chain Automation technology that allows AI agents and smart contracts to interact seamlessly across various blockchain networks. They are looking for a Senior Software Engineer to architect and guide the development of their Solver network—the core infrastructure powering NEAR Intents. In this role, you'll lead engineering design and implementation, enhance performance and reliability, and build the next generation of intent‑powered cross-chain execution. MISSIONS Design & build the Solver framework: Architect the algorithms, execution strategies, and infrastructure that power solver competition, quote aggregation, and intent-ready execution workflows. Drive technical excellence: Lead deep code and design reviews, make high-impact architectural decisions, and uphold the highest engineering standards. Collaborate across teams: Work with product, research, and ecosystem partners to align Solver capabilities with the NEAR Intents roadmap. Guarantee performance at scale: Ensure low-latency, high-throughput execution across chains and decentralized environments. Innovate Solver economics: Shape incentive structures, competition mechanisms, and cryptoeconomic models to grow and sustain Solver participation. Stay hands-on: Balance leadership with active coding, prototyping, and tackling the most complex technical challenges in real-time. Requirements 7+ years of software engineering experience. Deep expertise in distributed systems, high-performance networking, or large-scale infrastructure. Strong familiarity with smart contracts, on‑chain execution frameworks, or cryptoeconomics. Fluency in Typescript and Go is a must (experience in Rust is a plus). Proven ability to lead globally distributed engineering teams. Strong at abstracting complexity: breaking down organizational and technical challenges and driving them to resolution. Comfort in ambiguity: you move fast, take ownership, and delight in solving hard problems. Nice to Have Experience building MEV strategies, solver networks, or competitive auction mechanisms. Familiarity with cross-chain messaging protocols or cryptographic signature aggregation. Knowledge of AI/ML applied to optimization problems. Prior work in open-source ecosystems, especially in Web3-native protocols.
