About the role

As a Software Engineer in AIML Evaluation, you will

• Work closely with product managers, backend engineers, data scientists and other stakeholders to improve the overall quality and user experience of numerous Apple products.
• Design and develop evaluation system and framework to enhance the quality of Apple Intelligence, ensuring our AI/ML models meet the highest standards.
• Tuning evaluation infrastructure, tightening operational controls, improving auditability and debug trails, and scaling the workflows.
• You’ll play a pivotal role in developing Apple Intelligence, driving the next generation of groundbreaking products across all Apple platforms.

Responsibilities

• Benchmark Design & Development: Design and implement evaluation benchmarks, metrics, and test suites that rigorously measure model capabilities across reasoning, knowledge, code, and agentic workflows.
• Product-Aligned Evaluation: Develop evaluation methods that capture how models behave in real product settings, and validate that evaluation metrics predict user-perceived quality and product outcomes.

Evaluation Methodology Research & Tooling: Research and apply state-of-the-art evaluation techniques — including scoring frameworks, model-based judging, and contamination-resistant benchmark design. Build reusable tools, scorer libraries, and analysis frameworks that scale across the team’s benchmark portfolio.

• Experimental Analysis: Design and execute rigorous experiments comparing model capabilities, engage with third-party vendors on benchmarking, and perform detailed gap analysis to guide model development priorities.
• Cross-Team Collaboration: Work closely with model training, training data, and product teams to ensure evaluation insights inform training strategies, data decisions, and product quality improvements.

Minimum Qualifications

• 3+ years of professional software engineering experience building and operating production systems
• Ability to tackle complex challenges, think critically, and deliver innovative solutions.
• Fluent use of AI-assisted development tools (coding agents, code review assistants, etc.) to work effectively at scale
• Experience designing and scaling distributed systems (load balancing, active-active topologies, capacity planning, throughput-bound services)
• Experience with frontend web development (React and modern JavaScript frameworks)
• Experience with RESTful API design, SQL and NoSQL databases
• BS, MS in Computer Science, Computer Engineering, or equivalent degree with applicable experience

Preferred Qualifications

• Eager to explore and apply cutting-edge tech solutions.
• Experience working on large, cross-functional, and multi-team projects.
• Proven ability to operate independently on ambiguous, open-ended problems where the right answer is not obvious.
• Striving to elevate every aspect of the user experience.
