Defi Jobs in United States

About The Company

Inversion acquires and transforms legacy businesses using blockchain technology. Backed by $26.5M from Dragonfly and top VCs, the team builds crypto-enabled business models that bring real-world users on-chain.

About The Role

Architect and implement the Inversion Chain, an Avalanche-based L1, build core infrastructure, integrate DeFi apps, and ensure network reliability and scalability.

Responsibilities

• Architect and implement the Inversion Chain, a sovereign, Avalanche-based L1 optimized for consumer-scale performance, low latency, and business integration.
• Build core infrastructure modules, SDKs, and developer tooling that support rapid integration of real-world assets and applications across Inversion’s portfolio companies.
• Collaborate with external issuers or partners to integrate blue-chip DeFi applications.
• Support forthcoming Inversion-led products, such as mobile wallet and FinTech experience, providing frictionless UX comparable to top-tier fintech apps like Nubank or Robinhood.
• Contribute to validator infrastructure, tokenomics models, and interoperability frameworks that enable efficient migration of users and data from traditional systems to on-chain environments.
• Design, build, and optimize core consensus, networking, and execution layers of the Inversion Chain.
• Lead development of Inversion’s initial base contracts (e.g., collecting pre-deposits) and collaborate with external issuers or partners to integrate DeFi protocols.
• Serve as the technical architect; establish best practices for code quality, security, and performance.
• Develop, deploy, and maintain validator nodes, RPC infrastructure, and developer APIs to ensure network reliability and scalability.
• Partner with Product Managers and leadership to align protocol development with business objectives and user adoption strategies.
• Implement robust security frameworks, including cryptographic best practices, code audits, and formal verification processes.
• Continuously evaluate emerging blockchain protocols, consensus mechanisms, and interoperability standards to ensure Inversion stays on the cutting edge of protocol design.
