They build the kind of wonder that has reshaped entire industries. The diversity of our people and ideas drives the innovation behind everything we do, from breakthrough technology to industry-leading environmental efforts. Join Apple and help us leave the world better than we found it.\nThe iPhone System Engineering team is looking for an Engineer who is passionate about how iPhone performs. You will measure, model, and tune the power, performance, and thermal behavior of future iPhone SoCs and systems. You will work with a collaborative team that cares about getting the details right and about making the right architectural trade-offs\nOur team is collaborative and we are passionate about what we do. Come join us!\nDescription\nIn this role, you will:\nGet your hands on real SOC silicon and real iPhone systems: Run hands-on performance and power measurements with hardware and software tools. Dig into the data, find the root cause of unexpected behavior, and turn what you learn into clear optimization opportunities.\nArchitect for the trade-off: Analyze system behavior across the CPU, GPU, Neural Engine, and memory subsystem. Weigh power, performance, and thermal constraints against each other, and help decide where the next iPhone SoC and system should invest its power and silicon budget.\nProject the future: Build models, analyses, and simulations that project performance for upcoming iPhone products. Use them to influence architectural decisions across the hardware and software stack.\nSweat the details: Correlate models with measurements and question assumptions. Make sure the numbers behind each design decision hold up to scrutiny.\nPartner broadly: Work with silicon, hardware, and software teams, and present findings and recommendations to engineering and executive leadership to guide product direction.\nMinimum Qualifications\nBS in Electrical Engineering, Computer Engineering, Computer Science, and 3+ years of industry experience.\nExperience in computer, SoC, or system architecture for mobile devices.\nHands-on experience measuring performance with hardware and software tools.\nExperience in performance modeling, analysis, and debug.\nStrong programming skills in Python, and experience using AI tools to accelerate analysis and development.\nA detail-driven mindset, with the rigor to validate data and models before drawing conclusions.\nGenuine passion for system performance and for building great products.\nPreferred Qualifications\nMS/PhD in Electrical Engineering, Computer Engineering, Computer Science\n7+ years of industry experience in performance modeling and/or analysis\nDeep understanding of the hardware that drives performance, including the CPU, GPU, Neural Engine, and memory\nStrong grasp of how power and thermal limits shape system performance, and experience architecting trade-offs among power, performance, and thermal at the SoC or system level\nHands-on experience developing simulators or performance analysis tools\nGood interpersonal, communication, and presentation skills, including the ability to explain complex trade-offs clearly to both technical and executive audiences","description_format":"text","description_chars":3175,"description_truncated":false,"requirements":{"experience_years_min":7,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"bachelor","optional":true},"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Smartphones","Incident
