We are looking for an experienced Web Integration Engineer to join our Endpoint Security team and support the deployment and optimisation of a browser isolation solution, with a strong focus on Menlo Security products. This role is integral to ensuring secure, seamless, and high-performance web access across the organisation.

This position is ideally suited to someone with a strong foundation in web technologies, browser behaviour, and application compatibility, combined with excellent troubleshooting skills and the ability to work collaboratively across security and networking functions.

This is not a Front End development or UI-building role-its core focus is web integration, diagnostics, and resolving browser-level behaviours within a security environment.

The ideal candidate will be knowledgeable in IT, have a passion for Cyber Security, excellent interpersonal skills, and be a strong team player.

  • Networking Fundamentals: Understanding of proxies, DNS, TCP/IP, and experience with Firewalls, VPNs, and VLANs.
  • Scripting & Automation: Familiarity with Python, Bash, or similar for diagnostics or workflow automation.
  • Cloud Networking: Experience with AWS, Azure, or GCP networking tools and configurations.
  • Certifications: CCNA, CCNP, or equivalent are beneficial.
  • Communication: Ability to explain technical concepts clearly to non-technical stakeholders.

  • Web Development- Advanced
  • Web Integration & Troubleshooting- Advanced
  • Security Best Practices- Intermediate
  • Menlo Security Products- Intermediate
  • Network Configuration & Management- Intermediate
  • Scripting & Automation- Intermediate
  • Cloud Networking- Intermediate

Key Responsibilities

  • Partner with the Endpoint Security team to implement and support Menlo's browser isolation solution.
  • Lead efforts around web integration and application compatibility, including authentication flows, headers, cookies/sessions, and browser behaviour.
  • Diagnose and resolve web application and browser-related issues impacting the isolation platform, collaborating with network and security teams to identify root causes across clients, proxies, isolation layers, and application services.
  • Work with security analysts to ensure integrations comply with security policies and standards.
  • Create and maintain clear documentation covering configurations, known-issue patterns, and operational processes.

The successful candidate will play a crucial role in supporting the implementation of a browser isolation solution, specifically focusing on Menlo Security's products, with primary emphasis on web integration, browser behaviour, and application compatibility. This role requires strong web fundamentals, structured troubleshooting capability, and the ability to partner effectively with security and networking teams to ensure seamless integration and optimal performance.
