Applied Research Engineer — Multimodal AI

Applied Research Engineer — Multimodal AI Sunnyvale, California, United States Machine Learning and AI The Video Computer Vision (VCV) organization is a centralized applied research and engineering team developing real-time, on-device Computer Vision and Machine Perception technologies across Apple products. Within VCV, the Multimodal Intelligence team builds next-generation multimodal AI systems that combine large language models, multimodal LLMs, and foundation models to create intelligent systems capable of understanding, reasoning, and acting across language, vision, audio, and tools. We develop multimodal agentic systems deeply integrated into the Apple ecosystem, partnering across hardware, software, and ML teams to deliver advanced AI in real-time, scalable, and privacy-preserving experiences reaching millions of users. Description We are seeking an Applied Research Engineer with demonstrated experience in applied machine learning and generative AI. In this role, you'll build multimodal agent systems, translating research ideas into production-ready solutions for Apple products. Your work will encompass building and shipping agentic systems alongside developing evaluation tools and frameworks—understanding limitations, systematically analyzing failure modes, and creating methodologies to improve robustness, safety, and real-world generalization.This role offers the unique opportunity to impact millions of users while working at the intersection of research and production. You'll collaborate with world-class researchers and engineers, access cutting-edge hardware platforms, and solve novel problems in on-device AI that few organizations can address. Your work will directly shape how people interact with multimodal AI in Apple products.This role spans multiple dimensions of agent development — including context optimization, multi-turn orchestration, tool use, planning, evaluation, robustness analysis, and system optimization. Depending on experience and strengths, candidates may focus on different aspects of the agent lifecycle while contributing to the shared mission of building next-generation multimodal agents Responsibilities Design and develop agentic AI systems that reason, plan, and act across tools and modalities Develop supporting capabilities such as tool-use policies, multi-step reasoning evaluation harnesses, memory optimization, and performance optimization under real-time on-device constraints Prototype and evaluate novel approaches, combining research exploration with hands‑on engineering to translate innovations from concept to production Collaborate with ML engineers, platform teams, and product groups to adapt research innovations into scalable, reliable solutions meeting Apple's standards for performance, safety, and privacy Own end-to-end development of agent capabilities, from ideation and experimentation through evaluation, iteration, and integration into Apple products Minimum Qualifications MS in Computer Science, Machine Learning, AI, Robotics, or a related field (or equivalent practical experience) Strong foundation in machine learning and deep learning, including Agentic AI, reasoning, and large-scale models Demonstrated experience building production systems with LLMs and/or multimodal LLMs Proficiency in Python and in modern deep learning frameworks (PyTorch preferred) Preferred Qualifications PhD with research experience in agentic systems, reasoning, planning, or reinforcement learning Hands‑on experience building agents, including planning, task decomposition, tool use, and multi-step reasoning Experience with language or multimodal foundation models (training, fine-tuning, context optimization) Expertise in designing evaluation methodologies for agentic systems: scenario generation, failure analysis, robustness testing, and safety validation Publication record in top tier venues is a plus (NeurIPS, ICML, ICLR, CVPR, etc) At Apple, base pay is one part of our total compensation package and is determined within a range. This provides the opportunity to progress as you grow and develop within a role. The base pay range for this role is between $147,400 and $272,100, and your base pay will depend on your skills, qualifications, experience, and location. Apple employees also have the opportunity to become an Apple shareholder through participation in Apple’s discretionary employee stock programs. Apple employees are eligible for discretionary restricted stock unit awards, and can purchase Apple stock at a discount if voluntarily participating in Apple’s Employee Stock Purchase Plan. You’ll also receive benefits including: Comprehensive medical and dental coverage, retirement benefits, a range of discounted products and free services, and for formal education related to advancing your career at Apple, reimbursement for certain educational expenses — including tuition. Additionally, this role might be eligible for discretionary bonuses or commission payments as well as relocation. Learn more about Apple Benefits.
