• Capture customer feedback and market insights to influence product roadmap and GTM strategy

What You Bring:

• 4+ years of experience in enterprise software sales, ideally in cybersecurity, infrastructure, or AI-related solutions

• Background in cybersecurity or selling security solutions is a strong advantage, particularly experience engaging with CISOs, security architects, and risk teams

• Proven success selling complex, high-value solutions into large enterprise environments

• Experience operating as a product-focused seller or overlay specialist in partnership with core account teams

• Familiarity with LinkedIn Sales Navigator, HubSpot, and modern enterprise sales technology stacks

• Excellent communication skills with the ability to influence both technical and executive audiences

• Comfortable working to targets and managing pressure with professionalism and integrity

• Prior startup, scale-up, or post-acquisition integration experience is a plus

• Strong interest in AI, cybersecurity, and emerging enterprise technologies; knowledge of Generative AI and LLM ecosystems is a strong advantage

What You'll Get:

• Play a key role in shaping F5’s AI security portfolio following the CalypsoAI acquisition

• Work at the intersection of cutting-edge AI innovation and global enterprise adoption

• Engage with some of the world’s largest and most sophisticated enterprise customers
