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

  • 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.
