Job summary

Apple Inc. in San Diego seeks a senior stability engineer to keep large AI-augmented systems running reliably at Apple scale.

You will own the platform behind crash symbolication, data pipelines, and services used by engineers daily, extending capabilities with AI tools and hardening the production environment. You’ll prototype new capabilities, partner with stability analysts, and operate production systems with observability, incident response, and scalable workflows.

Qualifications

• 5+ years of professional software engineering experience building and operating production systems.
• BS in Computer Science or related field, or equivalent practical experience.
• Fluent use of AI-assisted development tools to work effectively at scale.
• Experience designing and scaling distributed systems (load balancing, active-active topologies, capacity planning, throughput-bound services).
• Track record of maintaining and evolving production services — observability, operational controls, incident response, and steady iteration on existing systems.
• Strong full-stack instincts; comfortable spanning data infrastructure, backend services, and the user-facing surfaces that consume them.
• Proven ability to operate independently on ambiguous, open-ended problems where the right answer is not obvious.

Responsibilities

• Run and improve stable, real production systems and platforms.
• Tune evaluation infrastructure and improve audit trails.
• Prototype and integrate AI-assisted capabilities into the platform.
• Collaborate with stability analysts and infrastructure teams.
• Operate in a demanding OS reliability environment to drive improvements.

Job description

San Diego, California, United States Software and Services

Are you a senior engineer who can keep large, AI-augmented systems runningreliably at Apple scale? Apple's Stability Engineering team is looking for aseasoned engineer to join our Core team. We build and operate theplatforms, services, and infrastructure that turn crash reports from Appledevices into actionable engineering insights. You'll work on systems whereLLMs and agents are already part of the production fabric — evolving them,hardening them, and using AI tools to extend what a small team can deliver.

Description

Our team owns the end-to-end platform behind stability analysis at Apple:symbolication of crash logs across the company's hardware portfolio, the datapipelines that aggregate and cluster crash logs, and the applications andservices that engineers across Apple use every day to drive operating-systemquality. This role is about keeping that platform healthy, extending itdeliberately, and making the engineering team itself more effective by usingAI tools well.Day to day, you'll spend most of your time on the engineering work of runningreal systems: tuning evaluation infrastructure, tightening operationalcontrols, improving auditability and debug trails, and scaling the workflowsour analysts rely on. When new capabilities are needed, you'll prototype andintegrate them into the platform. You'll partner closely with stabilityanalysts who are domain experts in OS reliability, and with the broader teamresponsible for symbolication, ETL, and service infrastructure. You'll alsobe expected to use AI-assisted development tools fluently to investigateissues, refactor at scale, and ship more with a small team.We're looking for someone with the rigor of a seasoned production engineerwho is also comfortable operating systems that include LLMs and agents asfirst-class components. If you enjoy taking responsibility for a complex,already-running platform and making it steadily better, we want to talk.

Minimum Qualifications

• 5+ years of professional software engineering experience building and operating production systems
• BS in Computer Science or a related field, or equivalent practical experience
• Fluent use of AI-assisted development tools (coding agents, code review assistants, etc.) to work effectively at scale
• Demonstrated experience designing and scaling distributed systems (load balancing, active-active topologies, capacity planning, throughput-bound services)
• Track record of maintaining and evolving production services — observability, operational controls, incident response, and steady iteration on existing systems
• Strong full-stack instincts; comfortable spanning data infrastructure, backend services, and the user-facing surfaces that consume them
• Proven ability to operate independently on ambiguous, open-ended problems where the right answer is not obvious

Preferred Qualifications

• Experience operating LLM- or agent-based features in production environments over time
• Experience building or maintaining evaluation harnesses, audit trails, or replay infrastructure for AI systems
• Background in developer tools, observability, crash/stability analysis, or other operating-system-quality domains
• Familiarity with one or more of: Ruby on Rails, Node.js/TypeScript, Python for production services
• Experience working in environments with significant deferred scalability work (capacity-constrained, long-lead-time infrastructure)
