Software Engineer (Engineer III to Principal) - Formal Methods

CertiK is a pioneering blockchain security company founded by professors from Yale and Columbia University, focused on securing the cyber world through innovative technology. The role involves designing and developing tools for automated verification of smart contracts, ensuring their correctness and security, while collaborating with a multinational team of programming language experts.

Responsibilities:

• Extend the scope and depth of our automated program verification tools and brainstorm, design, and implement new tools
• Adapt and improve algorithms for symbolic software model checking. Examples include bounded model checking (BMC), counterexample-guided abstraction refinement (CEGAR), and property directed reachability (IC3/PDR)
• Build and extend translators from different input languages into intermediate representations, optimizing the generated models for automated analysis
• Identify new classes of security properties of smart contracts and formalize properties for use in our automated verification tools
• Closely collaborate with other software engineers in developing tools and set technical direction for solving problems in consultation with your team and management
• Work on all aspects of delivering working software that meets customer needs, including analysis, design, automated testing, operations, CI/CD, measuring results, incorporating customer feedback, and support

Requirements:

• Master's Degree in Computer Science or a related field or 5 years of equivalent experience
• Minimum of 4 years of software development experience (includes internships, software developed during research, and open-source development)
• Minimum of 2 years of experience with one or more of the following: model checking, formal verification, SAT/SMT solving (Z3, CVC4, Yices, MathSAT, SMTInterpol), abstract interpretation, or closely related disciplines
• Demonstrated knowledge of fundamental computer science concepts such as data structures, algorithms, mathematical logic, and automata theory
• PhD in the broader field of automated reasoning
• Publication record in conferences like POPL, CAV, TACAS, FMCAD, FM, etc
• Experience in functional programming (OCaml or Haskell)
• Strong and creative problem-solving skills; always willing to learn and embrace new technologies and to collaborate
• Prior experience in a professional software development environment
