Why us? 
Blockchain technology is enabling a rapidly-growing era of innovation for the digital world. It is crucial that blockchain code such as protocols and smart contracts be correct. Once deployed, such code is public and difficult or not possible to change. Vulnerabilities and bugs in such programs regularly put millions of dollars at stake. 
This is where CertiK comes in. We are the leading blockchain security company. Our goal is to secure the cyber world by applying cutting edge techniques from academia to secure blockchain code. Come and join us to help work on tools for securing blockchain programs! 

What you will do
You will design and develop tools that automatically identify security issues or assist security auditors to locate security issues. You will collaborate with security auditors to understand blockchain security issues. You will have the opportunity to work on all stages of tool development from idea generation to implementation and iterative improvements. We develop and apply technologies such as static analysis, model checking, fuzz testing, language-based security (such as type systems), automated program verification, and theorem-prover based program verification. Our team is highly supportive and collaborative with great opportunities to learn and grow.

About you
You are a self-starter and excellent at programming. You love to solve problems and get results, where results are people using your tool to do their jobs. You believe in solving the most important problems, even if they are the most difficult ones. You are collaborative: you share ideas, love to brainstorm with peers, and give and receive feedback. You are comfortable with the unknown and understand that #startuplife means that you need to be creative, flexible, and focused on results.
