Job Description

Web Security Engineer (JavaScript / TypeScript) London / Remote to £80k

Do you have expertise with web security combined with strong JavaScript / TypeScript coding skills?

You could be progressing your career at a global leader in Computer Vision, AI and biometric identity, whose technology protects governments, critical infrastructure and some of the world's largest enterprises against identity fraud, deepfakes and sophisticated cyber threats.

As a Web Security Engineer you'll collaborate closely with the web development team to ensure security is at the centre of all web based applications. Joining a specialist security team, you'll focus on offensive web security, acting as the bridge between Security and Engineering. You'll perform penetration testing, reverse engineering and vulnerability assessments, identifying security risks and working closely with developers to build secure, resilient web applications from the ground up.

This is a highly collaborative role where you'll provide expert guidance on secure coding practices, influence architecture and design decisions and help embed security throughout the software development lifecycle.

Location / WFH:

You can work from home most of the time, meeting up with colleagues in the London office approximately twice a month for innovation sessions and team meetings.

About you:

  • You have strong experience in web application security and offensive security testing
  • You have hands-on expertise in penetration testing and reverse engineering
  • You have a deep understanding of modern web security vulnerabilities and mitigation techniques
  • You have commercial JavaScript experience, with TypeScript knowledge highly desirable
  • You're comfortable writing and reviewing production code, not just identifying vulnerabilities
  • You're collaborative and pragmatic, able to work closely with engineering teams

What's in it for You?

  • Salary to £80k
  • Bonus
  • Equity
  • Excellent career progression
