Full Job Description
The Vector and Numerics Group is tasked with designing, enhancing and improving various subsystems running on iOS, macOS, watchOs and tvOS. Most of this support is encapsulated in the Accelerate framework, a well used library serving many technologies.

The group is looking for an exceptional high performance programmer to complement the team and make a difference. As a member of our fast paced group, you will have the unique opportunity to delight and inspire millions of Apple's customers every day. You will work in a cross functional team which is implementing innovative and state of the art routines to support the necessary computation for such things as machine learning and vision algorithms. Push the state of the art in low level computation and drive them towards energy efficient and high performance implementations by tightly integrating software and hardware. The successful candidate will have excellent understanding and knowledge of micro architecture of NEON on ARM and AVX on Intel CPU cores from a vector programming perspective. Team members are engaged in the design and optimization of low level computational support for machine learning and computational vision such as 2D Multi-layered convolution, LSTM in hand writing recognition, FFT and DFT for audio codecs, speech synthesis and encryption to mention a few technologies. Understanding and working knowledge of cryptographic algorithms such as AES and SHA is a desirable attribute. Being able to craft the fastest and the most energy efficient routines for a particular CPU core is a plus. Low level high performance programming experience is a must for this position. Being comfortable in vector assembly and low level C is a requirement. The ideal candidate would be at ease in developing both innovative and robust CPU core level algorithms derived from a particular technology's need in a tight deadline .

5+ years low level algorithmic development in Machine Learning computation, LSTM, BLAS and DFT. Detailed knowledge of vector Instruction Set Architectures (ISA) of ARM and Intel. Strong understanding of computational efficiency. Excellent coding skills in ASM and C.

Strong verbal and written communication skills. Ability to manage multiple tasks and self-prioritize. Ability to work with cross functional teams in compression related components.

About Apple

Apple is a corporation that designs, manufactures, and markets mobile communication and media devices, personal computers, portable digital music players, and sells a variety of related software, services, peripherals, networking solutions, and third-party digital content and applications. Apple provides many products and services, including iPhone; iPad; iPod; Mac; Apple TV; a portfolio of consumer and professional software applications; the iOS and OS X operating systems; iCloud; and accessories, service, and support offerings. It sells its products worldwide through its retail stores, online stores, direct sales force and third-party cellular network carriers, wholesalers, retailers, and value-added resellers to the consumer and also sells third-party iPhone, iPad, Mac and iPod compatible products, including application software and accessories through its online and retail stores. Introduced in 1984, the Macintosh was the first widely sold personal computer with a graphical user interface (GUI). That feature and others such as an improved floppy drive design and a low-cost hard drive that made data retrieval faster helped Apple cultivate a reputation for innovation. Apple was named as the most admired company in the United States in 2008 and in the world from 2008 to 2012 by the Fortune magazine. The company was founded by Steven Paul Jobs, Steve Wozniak, and Ronald Gerald Wayne on April 1, 1976, and is headquartered in Cupertino, California.
