About the Role

You will play a key role in building and scaling the product. This is a high ownership position where you’ll take responsibility for meaningful work from day one, collaborate closely with cross functional teams, and help turn ambitious goals into real world outcomes. Your mission is to move fast and raise the bar. You’ll operate in a dynamic, high growth environment, navigate ambiguity with confidence, and contribute to systems, products, or processes that scale. Quality matters, speed matters, and ownership is non negotiable. This role is for builders, people who take initiative, think in systems, and care deeply about doing great work. If you’re excited about working at the intersection of technology, execution, and impact, you’ll feel right at home.

• Mastery: Expert-level React, Node.js, and Cloud (AWS/GCP) fluency.
• Leadership: Experience leading large-scale feature deployments and managing technical debt.
• Communication: Ability to explain complex technical trade-offs to product managers and designers.

Responsibilities

• Architectural Influence: Lead the design of complex subsystems and ensure the stack evolves with industry best practices.
• Critical Problem Solving: Debug high-priority production issues and optimize cloud infrastructure for cost and performance.
• Mentorship: Elevate the entire team’s output through rigorous reviews, technical workshops, and standard-setting.
• Web3 Integration: Lead the integration of DApp features, smart contract interactions, and wallet providers.
