Sr Security Incident Response Engineer, AIS

Imagine what you could do here. At Apple, new ideas have a way of becoming extraordinary products, services, and customer experiences very quickly.

Apple Information Security is looking for an experienced Incident Response engineer to help protect Apple, our customers, and our data. This is work where the stakes are real, the scope is global and the decisions you make during an incident shape outcomes across the company.

We're a diverse collection of thinkers and doers who are continually reimagining how threats get identified, contained, and mitigated. You'll bring deep technical judgment, the instinct to anticipate an attacker's next move rather than only recognize the last one, and work with other responders to build a stronger team. This is a deeply collaborative role where operations, critical thinking, and technology converge, and where you'll be trusted to own hard calls and build the capabilities the team relies for handling complex security incidents.

Bring your passion and dedication to this job, and there's no telling what you could accomplish.

Apple Information Security is seeking a senior security professional to join its Incident Response team. The successful candidate brings a proven technical background and substantial Information Security experience, with deep focus across the incident response lifecycle.

You'll work with a global team of security professionals on a follow-the-sun model, focused primarily on the identification, containment, and mitigation of security incidents. You'll be trusted to drive complex, ambiguous investigations to resolution with minimal guidance, to set the bar for investigative quality, and to up-level the team around you. You'll also help move the function forward, turning what you learn in one investigation into durable capability the whole team benefits from. This person will have the opportunity to work on technology and processes with global reach.

Own incidents end to end: Handle and analyze security events and incidents, driving each through every stage to resolution. You'll form and test hypotheses, establish root cause, determine blast radius, and make containment and remediation decisions with minimal guidance — escalating with clear reasoning when the situation warrants it.

Mentor and grow other responders: Coach less experienced members of the team, tailoring how you explain your thinking to what the other person already knows. You'll set the bar for investigative quality and help raise it across the function — this is a core expectation of the role, not a secondary one.

Build durable capability: Turn one-off investigations into things that last: detections, queries, reusable processes, automations. You'll drive initiatives that scale incident response through creative technical solutions rather than additional headcount.

Analyze at scale: Define strategies to scope incidents and surface risk through data analysis — working fluently with raw telemetry and context-switching across data sources under time pressure.

Influence beyond the team: Partner with organizational units across Apple to strengthen security posture and processes, serving as a trusted technical advisor on response matters and bringing clarity to stakeholders with very different levels of context.

Collaborate globally: Work as part of a distributed team protecting Apple, coordinating across time zones and functions to keep security a priority.

Schedule and coverage: This role primarily follows a Monday through Friday schedule, with an on-call rotation covering weekends and holidays. A shift-based schedule may also be required in the future.

B.S. in Computer Science, Engineering, or similar degree and/or equivalent 5+ years of experience in Information Security with a focus on Incident Response, Security Engineering, and/or Intrusion Detection, including significant hands-on response work

Demonstrated ability to drive investigations independently — comfortable testing hypotheses, establishing root cause, and applying policy and remediation strategies

Demonstrated experience mentoring and coaching other responders, sharing expertise in a way that measurably improves the work of those around you

Strong understanding of incident response automation strategies, with a track record of implementing them

Proficiency in one or more programming or scripting languages

Proven ownership of complex, ambiguous problems through to resolution, with sound judgment about what to decide and when to escalate

Strong understanding of threat modeling, operational threat intelligence, and common attack vectors

Strong understanding on AI to apply innovation into IR processes through controlled, replicable and traceable strategies.

Deep working knowledge of modern identity management, with the ability to reason about and determine blast radius within an incident

Practical understanding of attacker tradecraft sufficient to anticipate the next step rather than only recognize the last one

Has repeatedly turned a one-off investigation into durable capability — a detection, a query, a reusable process

Curiosity about emerging attack surfaces and vectors

Fluency analyzing large-scale datasets, context-switching between data sources, and working directly with raw telemetry during investigations

Working competence across several of: endpoint/OS internals, cloud control planes, SaaS platforms, corporate IT infrastructure, and developer/CI-CD environments

Experience in malware analysis, digital forensics, intrusion detection, and/or threat intelligence

Technical certifications are a plus (OSCP, GIAC, CCNP/CCIE, and similar)

Excellent verbal and written communication skills, including the ability to brief audiences with varying levels of technical context
