iPhone is the most popular camera in the world, and the Aesthetics Science team is focused on infusing photographic knowledge and personal preferences into the features and algorithms that power it. We bring together aesthetics research, image processing, and machine learning to help advance photography while upholding what makes it a beloved medium for self-expression. You'll have real ownership over how these creativity-enhancing features come together into a coherent, best-in-class experience.

Description

We're seeking a self-driven, innovative research engineer to work on image-related machine learning solutions fundamental to visual experiences on iPhone and across Apple's creative ecosystem. You'll research, implement, and evaluate novel computational imaging features and multimodal solutions that shape future Apple products.

You bring solid experience designing, training, and analyzing multimodal models and evaluation frameworks end-to-end - combined with a passion for photographic aesthetics and high-quality software for visual creativity and image generation. Day-to-day responsibilities include prototyping novel algorithms, training and evaluating ML/generative AI (genAI) models, and designing custom data collection efforts.

This role involves close collaboration with our research and user study teams to design thoughtful experiments and translate the results of complex subjective studies into feature development, working alongside subject matter experts across visual media to build responsible, intelligent systems. Your work will be highly collaborative, both within the team and cross-functionally, requiring you to communicate technically and creatively toward a smarter, more inclusive camera.

About This Role

Research Engineers bridge the gap between research and production. They implement papers, build experiment infrastructure, optimize training pipelines, and make research prototypes production-ready. They're the engineers who make research work at scale.

The role sits at a unique intersection. You need to understand the math well enough to implement novel architectures correctly, and you need the engineering chops to make them run efficiently on distributed systems. When a research scientist has a breakthrough idea, you're the person who turns it from a notebook prototype into a training pipeline that runs on 256 GPUs.

Across the 9,079 AI roles we're tracking, Research Engineer positions make up 2% of the market. At Apple, this role fits into their broader AI and engineering organization.

Research Engineer roles are growing as AI labs recognize that research velocity depends on engineering quality. The role is less competitive than Research Scientist (no PhD required), but the bar for engineering skill is very high. These roles are concentrated at major labs and well-funded startups.

What the Work Looks Like

A typical week involves: implementing a new attention mechanism from a recent paper, profiling and optimizing a training pipeline that's bottlenecked on data loading, building evaluation infrastructure for a new benchmark, debugging distributed training issues across a GPU cluster, and pair-programming with a research scientist on their latest experiment. The work is deeply technical.

Skills Required

Python (18% of roles)

Strong software engineering fundamentals plus ML knowledge. Python, C++, and CUDA experience are common requirements. You'll need to read papers and turn ideas into working code. Distributed systems experience (especially distributed training) is highly valued. Performance optimization skills separate great candidates from good ones.

Experience with large-scale training infrastructure (FSDP, DeepSpeed, Megatron), GPU programming (CUDA, Triton), and the internals of ML frameworks (PyTorch internals, custom autograd functions) is what makes candidates stand out. The best research engineers can debug issues that span the full stack from GPU memory management to numerical precision to algorithmic correctness.

Strong postings mention the team's recent research, the infrastructure scale, and the specific technical challenges. They often list the research areas you'd support. Look for roles that emphasize both implementation quality and research understanding.
