Join us in changing the world!

If you are an extraordinary technologist who loves creative problem solving, can interface with clients just as well as operating systems, and wants to build an enduring, impactful organization, we want you on our team!

  • Analyze application and infrastructure security utilizing penetration testing
  • Investigate suspected cybersecurity breaches and run forensic investigations
  • Perform incident response and disaster recovery, including steps to minimize impact and restore critical operations
  • Help clients successfully integrate technologies such as AI into their business while providing guidance around security and privacy risks
  • Build relationships with existing clients and obtain new clients of your own, leading complete sales cycles, including proposal writing and closing the deal!

What you’ll bring:

  • Strong client-focused work ethic
  • Passion for technology
  • The ability to multitask and re-prioritize on the fly
  • A keen eye for detail and incremental improvements
  • Ability to thrive in a fast-paced, high-action environment
