  • You'll guide and mentor other software engineers specially focusing on software design and architecture
  • You'll maintain and improve existing code with a pride of ownership.
  • You'll lead large projects and be self-driven


  • 8+ years total development experience
  • Extensive software engineering experience in C++ (Python is a plus)
  • Experience in advanced development, especially in distributed systems and large, complex system environments deployed at scale


  • Experience in building authentication, authorization, and data security end-to-end products or features
  • Some experience working with security technologies (SSL/TLS/X.509/SAML/OAuth/JWT/KMIP/PKCS#11/, etc..)
  • Some experience with low level cryptographic mechanisms like (AES/GCM/PBKDF2/HMAC/SHA2/ etc..)


BS, MS or PhD in Computer Science or related engineering discipline, with security emphasis highly preferred.
