features, you’ll make sure everything we ship is secure, from design through
security testing to delivery, using AI to scale how we find and fix issues.

DESCRIPTION

As the lead security engineer for Sales Engineering in London, you will set the
security direction for our platforms, working with engineering teams and
security counterparts across our global organisation. You’ll work on both live
codebases and new platforms, building security in from the start while keeping
teams shipping, in close partnership with Apple Information Security. Your
day-to-day will mix architecture-level thinking with hands-on technical work.
You’ll run threat modelling, analyse complex system dependencies, investigate
vulnerabilities, and lead security practices for the teams you support. You’ll
also put AI developer tools to work, using them to triage findings, generate
security tests and draft fixes, so that security keeps pace with a large
portfolio.

production software, through code review, security testing or investigating
real-world issues. Strong software engineering fundamentals and fluency in at
least one modern general-purpose programming language. A track record of owning
security for complex software platforms, from design through to operation. Deep
expertise in securing distributed systems and cloud platforms at scale,
including PKI and certificate lifecycle management, TLS and mutual TLS, service
and device authentication, secrets and key management, and software supply chain
security.

PREFERRED QUALIFICATIONS

Excellent written and verbal communication, with the ability to explain security
risk clearly and win support for security decisions from engineers and senior
leaders. Experience embedding security into CI/CD pipelines and developer
workflows, e.g. static analysis and dependency scanning. Practical experience
applying AI developer tools to security work, such as code analysis, test
generation or triaging findings. BSc or MSc in Computer Science or equivalent
practical engineering experience.
