Location: London
Job Description:

A global technology group with a long-standing reputation for disciplined growth and long-term investment is expanding its product security capability following increased board-level focus and funding.

As products become more connected, software-driven, and deployed in operational environments, the organisation is strengthening how security and privacy are built into products from design through to deployment.

This is a newly created senior role, forming part of a multi-year, globally scoped programme with executive sponsorship.

The Senior Product Security Specialist will work across an international portfolio of engineering-led businesses, focusing on the security of products that combine hardware, software, and connected technologies.

The role is hands-on and assessment-led, with regular international travel to work directly with engineering and product teams in real-world environments.

Key Responsibilities

  • Conduct threat modelling for software and hardware products, including embedded systems and industrial / operational technology environments
  • Identify and assess design-stage security and privacy risks across the product development lifecycle
  • Evaluate product security across:
  • Embedded firmware and IoT products
  • Web applications and digital services
  • Supporting cloud and data processing components
  • Perform structured product security assessments and provide clear, actionable remediation recommendations
  • Communicate product security and privacy risks effectively to engineering teams and senior stakeholders

This role is focused on product security and secure product development, not SOC operations or compliance-only governance.

Experience Required

  • Demonstrated experience securing products, rather than solely enterprise IT or cloud platforms
  • Strong background in threat modelling across embedded, IoT, industrial, or software-driven products
  • Solid understanding of secure product development lifecycles and privacy-by-design principles
  • Comfortable working independently in complex engineering environments and influencing without authority
  • Clear, professional communication skills suitable for senior technical and business audiences
  • Willingness and ability to travel internationally on a frequent basis
  • Experience applying recognised security standards and frameworks such as: ISO/IEC 27000, ISA/IEC 62443, NIST SP 800-218.

You will be expected to clearly articulate product security and privacy risks to senior technical and business stakeholders, providing insight that informs executive and board-level decision-making.
