Summary:
Reality Labs is seeking an Mechanical Engineer to lead the design of internal data collection hardware. The Data Systems Hardware & Operations team designs, builds, and deploys the devices and systems used to capture the datasets behind Reality Labs products. This work spans development of data collection headsets and wearable proto@types, sensor-integrated form factor mockups, and the necessary infrastructure to integrate these systems into data collection operations. These systems support Codec Avatars, Input, and Health programs across all Reality Labs devices, and enable the algorithm development and research behind those programs.This role owns mechanical architecture and design for data collection devices from concept through deployment to collection sites. Design work centers on head-worn and body-worn proto@types: integrating sensors (cameras, IMU, audio, etc.), illumination, and data aggregation into wearable form factors, holding sensor alignment and repeatable positioning across participants, managing thermal and mass distribution under wear constraints, and meeting fit, comfort, and participant safety requirements across a range of head and body geometries. Proto@types must be durable enough for sustained use by non-engineering operators and serviceable in the field.The role operates across mechanical, optical, electrical, systems, and firmware boundaries, and partners with research, program management, and data collection operations.Full system requirements are often undefined at project start. Research direction and program priorities shift, and requirements are established through prototyping and measurement. Candidates should have experience working in high-ambiguity, fast-paced development environments.
Required Skills:
Mechanical Engineer, Data Systems Hardware Responsibilities:
Own mechanical architecture and design for data collection headsets, wearable proto@types, and the infrastructure necessary to integrate them into data collection operations
Design head-worn and body-worn hardware that integrates sensors (cameras, IMU, audio, etc.), illumination, and data aggregation into wearable form factors while meeting sensor alignment, fit, comfort, mass distribution, and thermal requirements
Provide start-to-finish ownership of mechanical design and implementation, partnering with internal stakeholders (electrical, firmware, systems engineering, program management, and operations) and external stakeholders (production engineering, supply chain) to deliver devices on schedule and to specification
Translate research and program roadmaps into mechanical system requirements, and convert prototyping and test findings into documented specifications
Define and communicate system-level trade-offs across performance, cost, manufacturability, wearability, deployability, schedule, and risk to align cross-functional stakeholders and leadership
Design for sensor location repeatability across participants and sessions, including adjustment mechanisms, sizing strategies, and fit across a range of head and body geometries
Take data collection concepts from early proto@types and proof-of-concept builds through to replicable devices deployed across multiple collection sites
Build and iterate rapidly, running build, measure, and revise cycles to resolve open technical questions and establish requirements
Support proto@type fabrication and builds, working with internal and external partners on part fabrication, fixture and assembly tooling design, and assembly procedures
Design test fixtures, calibration fixtures, and capture support hardware required to characterize and validate data collection devices
Define and execute test and validation plans, including measurement, data analysis, and refinement of design assumptions
Design for transport, field assembly, and reconfiguration across distributed collection sites, and support device bring-up and troubleshooting on site
Establish mechanical design standards, common platforms, and reusable subsystems to reduce the cost and schedule of subsequent device builds
Perform root-cause analysis on electromechanical failures in deployed hardware, implement design improvements, and verify effectiveness
Create and maintain assembly instructions, fit and donning procedures, test procedures, maintenance logs, and design rationale documentation to support repeatable builds and handoff to partner teams
Balance and sequence mechanical work across Codec Avatars, Input, and Health programs with competing timelines and resource needs
