Do you love working on challenges that no one has solved yet? Do you like changing the game? Envision what you could do here. At Apple, we believe new ideas have a way of becoming extraordinary products, services, and customer experiences very quickly. Bring passion and dedication to your job and there's no telling what you could accomplish.

This position contributes to the development and qualification of advanced lithium ion battery technology for portable power consumer applications. You will work with internal multi- functional teams to develop battery cell and battery management system (BMS) qualification protocols using system requirements, user profiles and the battery aging model to ensure high level of customer experience. You will collaborate with cell and BMS testing engineers to execute the qualification protocols and explore new testing methods to improve productivity and efficiency. You will work with cell development engineers and a data analytics team to understand battery field failure mechanisms and develop models to detect battery abnormalities early in advance from the field.

Key Qualifications

    • Three years or more of physics-based modeling of electrochemical processes and performance characterization experience with emphasis on lithium ion or lithium polymer batteries aging model.
    • Working knowledge of Matlab.
    • Familiarity with applicable battery test equipment, test procedures, international standards and failure analysis applicable to rechargeable lithium battery products
    • Familiarity with current state of the art production processes applicable to lithium rechargeable cells
    • Experience applying quality tools and their application to development, characterization and production of lithium batteries, including statistical analysis of performance results, process capabilities, and design of experiments
  • Strong aptitude in mathematical modeling of linear and nonlinear dynamical systems and distributed parameter systems.

  • Ability to motivate and work independently with minimal mentorship required

  • Ability to interact effectively with other engineers and teams

  • Strong process oriented and data driven work culture

  • Self-starter with excellent time management skills and entrepreneurial spirit

  • Ability to clearly understand and explain technical issues

  • Support and justify technical decisions based on data and results


  • Collaborate with cell and BMS engineers on defining qualification testing protocols. Use user profiles, battery aging model and system requirements to ensure high level of customer experience

  • Review, Analyze and Report Qual Result Data From Cupertino and Vendor Labs.

  • Flag and report anomalous qualification output and perform FA to identify RC for deviation.

  • Standardization of Qual Test Plans Across Labs to Improve Uniformity and Reliability of Qual Data

  • Identify opportunities to streamline Cell Qual

  • Reporting on KPI and monitoring timely execution of tests.

  • Improvement of Vendor Qual

  • Work with cell development engineers and a data analytics team to understand battery field failure mechanisms and develop models to detect battery abnormalities early in advance from the field

VIEW JOBS 5/8/2020 12:00:00 AM 2020-08-06T00:00 The Debugger Technologies team at Apple is looking for an engineer to work on the delivery and testing of the LLDB debugger. LLDB is a core part of Apple's developer tools, used internally to debug Apple's software stack and externally by millions of developers. We are looking for a debugger engineer to join our efforts. Our team works to deliver reliable tools for all developers working on our platforms. We strive to build a diverse, balanced and dynamic environment! You will join a team of motivated engineers who build first-class debugging tools. We hire people at Apple to do the greatest work of their lives and revolutionize the state of the art in their field. As the saying goes, "Debugging is twice as hard as writing the code in the first place". Your work on our team will help countless developers be more productive and ship best in class apps for Apple platforms, current and to come. Far more than any specific experience or skill, we are looking for engineers who want to build great software, learn and develop their skills, and ultimately enable others to develop amazing applications. Key Qualifications * Proficiency in Python scripting for automation * Experience with build systems (CMake is a plus) * Passion for crafting software and tools * Strong communication and teamwork skills * Positive and respectful attitude in a diverse environment Description In this position, you will be in charge of the LLDB debugger's testing on the growing number of Apple platforms. You will work closely with the rest of the team to maintain and improve LLDB's qualification matrix. You will develop new testing strategies to catch regressions before they affect our internal users. Internally, you will collaborate with other teams, including our kernel and runtime teams, to make sure their changes don't impact the debugging experience negatively. Last but not least, you will also be in charge of the delivery of LLDB to our internal and external users, in close collaboration with the Swift and Clang teams. You'll join a team based in Cupertino, California. You also will work closely with the larger developer tools organization colocated with us. Our team has a wide range of experience. New team members quickly get to own a part of the debugger and develop independence in their work. We will consider non-US applicants and are open to exploring visa options, provide relocation assistance, and offer excellent benefits. Education & Experience B.S. in Computer Science or equivalent experience Additional Requirements * If possible, we'd love to see an example of your relevant work, such as a personal project or open source contribution Apple Inc.
