Summary（岗位介绍）

As a Hardware Systems Architect at Reality Labs, you will lead architecture on upcoming AR/VR/Wearables products, help drive the overall strategy & roadmap, and be a part of the teams designing, building, and testing prototypes for future consumer AR/VR/Wearables reality experiences. We want people who work well in teams, can brainstorm big ideas, work in new technology areas, thrive in ambiguity, are able to map tradespaces, are able to drive a concept into a prototype, and can envision how a prototype could transition into a high-volume consumer product.

The Reality Labs Hardware Systems Architect will lead the definition and convergence of complex and novel sub-systems, and product architectures aimed at pushing beyond the state-of-the-art consumer AR/VR/Wearable systems. These can span new sensing systems, display/optics systems, input devices, and full VR headsets. The role requires expert technical communication with cross-functional teams across ID, hardware engineering, partnerships, supply chain and core technology groups to drive incubation of new technologies from proof of concept through integration into products for mass production. This role requires excellent technical understanding of consumer electronics and AR/VR/Wearable reality systems across the stack.

Starting with a broad engineering background in electrical engineering, computer science, semiconductors or related fields, we’re looking for a unique system designer or architect. The ideal candidate would have strong systems skills, previous roles driving architecture convergence on complex consumer electronics products, and experience with SoC evaluation, optical systems, sensors, CV algorithms, software, and be able to work collaboratively with experts in different fields to make architectural trade-offs. In addition, this role requires past experience architecting systems to run ML workloads - assessing and selecting appropriate ML compute cores and driving system-level optimization of performance, power, latency and memory usage.

Experience in rapid prototyping and creating proof of concept models to share ideas and improve architectural decisions

Communication experience working with Product Development engineers, Product Managers and other hardware/software cross-functional teams

Experience working with partnerships teams and external partners at both a supply base and product level

Description（岗位职责）

Own system architectures encompassing compute, displays/optics, EE, sensors, calibration, and firmware from initial conception through prototyping, product development, and production ramp

Across a portfolio of products, work with ML scientists and SW engineering teams to understand requirements for ML workloads that need to be supported. Drive selection/definition of compute silicon that has appropriate HW accelerators/cores for these workloads

Lead product architecture for roadmap products, communicate trade-offs, program concerns and technical direction with specific focus on enabling ML-assisted augmented/virtual reality experiences

Drive the technical scoping and development of new technologies to deliver generation-defining user experiences for future products on the roadmap

Conduct detailed analysis and trade-off studies for complex systems

Engage with technology project leads, and various component SMEs in creating the overall system architecture and platform as the starting point for product execution

Deliver engineering solutions for the most challenging architectural problems in early phase concept development (ensuring translation of marketing requirements to product)

Communicate technology and product strategy effectively to both internal and external stakeholders

Partner with management and cross functional teams on long term technology investments

Create proof-of-concept physical prototypes

Collaborate with cross-functional teams on blank-slate and early-phase prototyping and product exploration, mapping it to strategic and product questions which need to be resolved

Create hardware system metrics, KPIs, standards and tools

Travel up to 15% time domestically and internationally

Additional Requirements（额外要求）

MS/PhD in Electrical Engineering, Computer Engineering other related technical field or equivalent experience

Experience in firmware development, programming, computer vision, OS, game development, and complex sensing systems

Experience modeling system power and, using those models, inform trade-offs against key architectural decisions (e.g. battery life, thermals, silicon roadmaps, power load profiles)

Understanding of memory subsystems including mass storage and filesystem as well as volatile memory and memory management and their impacts on overall system performance

Experience with AR/VR or systems aimed at capturing/processing/delivering audio visual, IMU or other positional data streams

Experience creating system models to analyze system compute, latency and communication interface bandwidths across multiple subsystems within a heterogeneous compute environment in order to define the system architecture to meet the overall goals of the product definition

Experience with influencing silicon vendors roadmaps and SOC features sets with emphasis on using advanced IP in the realms of Machine Learning, Graphics and Imaging
