  • Work closely with security and network teams to resolve complex problems

  • Support and optimise Menlo's browser isolation platform

What We're Looking For

  • Strong web fundamentals and advanced troubleshooting skills

  • Experience with browser behaviour and web app integration

  • Solid understanding of networking (DNS, proxies, TCP/IP)

  • Scripting skills (Python/Bash) are a plus

  • Exposure to cloud platforms (AWS, Azure, GCP)

  • Interest or experience in cybersecurity
