The Security Services team is dedicated to helping organizations design secure and efficient blockchain systems, encompassing a wide array of applications from decentralized exchanges (DEXs), smart contracts, and decentralized finance (DeFi) platforms to interchain connection protocols that enable seamless communication and interoperability between diverse blockchain networks. Informal systems approaches combine manual code inspection with automated software analysis using our in-house formal verification and testing tools.

  • Participate in security incident response activities, conducting investigations, and providing remediation recommendations when necessary.
  • Lead the development and enhancement of internal security tools and methodologies for blockchain security assessments and audits.

What we look for in a successful Security Architect:

  • Educational and research background in distributed computing, information security, formal verification, or comparable. Ideally you hold a PhD or equivalent experience in one of these domains.
  • Software engineering experience related to complex distributed systems, either on the design, implementation or the testing side.
  • Experience with app-chain blockchain frameworks, in particular for Cosmos Strong programming skills; experience with Golang, Rust or Solidity is a plus.

  • Familiarity with modern infrastructure tools and testing approaches.
  • Excellent analytical and problem-solving abilities, with a keen eye for detail.
