Cohere's North team is seeking a Senior Software Engineer with a focus on security to join our mission and make a significant impact.

Job Responsibility

  • Build and ship security features for North, our AI workspace platform
  • Develop autonomous agents that talk to sensitive enterprise data
  • Write and ship minimal code that runs in low-resource environments, and has highly stringent deployment mechanisms
  • Pulling in new tools to enhance North's security capabilities

  • You have strong development skills, and have shipped (lots of) Python in production
  • You have a solid knowledge of security principles like session management, multi-factor authentication, and secure coding practices
  • You have strong coding abilities and are comfortable working across the stack. You’re able to read and understand, and even fix issues outside of the main code base
  • You employ a flexible and constructive approach when solving problems
  • You excel in fast-paced environments and can execute while priorities and objectives are a moving target

What we offer

  • An open and inclusive culture and work environment
  • Work closely with a team on the cutting edge of AI research
  • Weekly lunch stipend, in-office lunches & snacks
  • Full health and dental benefits, including a separate budget to take care of your mental health
  • 100% Parental Leave top-up for up to 6 months
  • Personal enrichment benefits towards arts and culture, fitness and well-being, quality time, and workspace improvement
