We invite you to be a part of our team of smart, professional, result-oriented and fun individuals. Join us to help ensure that our background processes run smoothly while we are striving to become the best in the industry.

About the Position

We’re looking for a Senior Software Engineer (Solvers) to architect and guide the development of our 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.

Responsibilities

• 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.
