Navigating complex technical problems and providing insight, technical direction, and technical execution will be your day-to-day.The ability to build a solid working relationship with our core product engineering team and others including compliance and legal is a must.

  • Map processes identifying automation and security/fraud risk reduction opportunities across lines of business
  • Design and implement systems and processes to enable a more security overall platform with an emphasis on the safekeeping of cryptocurrencies
  • Partner with business stakeholders to truly understand what and how the company runs and proactively identifying areas where security tools can be implemented or existing tools enhanced to minimize business risk, and ideally, drive business value

About You: 

  • Deep knowledge of the cryptocurrency ecosystem (BTC, ETH, etc.) and underlying technologies (blockchain, PoW, PoS, etc.)
  • Experience designing technical security protocols using cryptographic systems (SSS, MPC, etc.)
  • Understanding of technical enterprise security controls based on US and international frameworks (ISO, NIST, etc.)
  • Experience building internal tools in Javascript, Python, Bash, or similar languages
  • Working knowledge of physical security best practices and the ability to think adversarially when designing and implementing controls
  • Able to work independently while maintaining transparency and collaboration with a larger team
  • Excellent written and verbal communication skills, specifically able to document highly technical concepts, including operating procedures, for non-technical audiences
  • Demonstrated ability to continuously learn, work independently, and make decisions with minimal supervision
  • Ability to work effectively in teams of technical and non-technical individuals
  • Have extreme attention to detail without sacrificing execution rigor
  • Bias towards action and own tasks end-to-end
  • Work through hurdles and tactfully navigate the organization driving towards the objective
  • Be a doer that can get things done and unblock tasks while building deep organizational relationships along the way
  • Be thoughtful and analytical - ask why and challenge preconceived notions
  • Ability to work independently with minimal supervision
  • Own the company’s problems like they are your own
  • Obsessive drive and passion for security and building products people use

Above all, you should enjoy the journey. We, at BlockFi, genuinely like each other and enjoy the work we do - so should you!
