SW Specialist - Wearables Interfaces Engineering

About the job

As a SW Specialist on the Wearables Interfaces Engineering team, you will serve as a technical leader responsible for optimizing and integrating platform-level software that runs atop Meta's wearable device stack. Working closely with the Core OS team, you will bridge the gap between operating system capabilities and the application/experience layers. This position requires a holistic view across firmware, OS interfaces, frameworks, middleware, and applications to ensure seamless platform integration and optimal device performance. You will drive cross-functional system design decisions, resolve complex multi-component issues, and set the technical direction for how platform software leverages Core OS to deliver immersive user experiences.

Responsibilities

Platform Architecture & Integration: Drive platform software architecture for wearable devices, ensuring coherent integration across Core OS interfaces, frameworks, middleware, and application layers Cross-Stack Technical Leadership: Lead system-level initiatives that span OS-to-application boundaries, optimizing frameworks, system services, and applications for performance, reliability, and power efficiency End-to-End System Debugging: Own resolution of complex, ambiguous issues that span multiple components—OS interfaces, drivers, frameworks, and application software—identifying root causes and driving fixes across teams including Core OS System Performance & Optimization: Analyze and optimize platform-level performance, latency, memory usage, and power consumption across the framework and application stack Core OS Partnership: Collaborate with the Core OS team to define platform requirements, influence OS roadmaps, and ensure platform needs are met by underlying OS capabilities System Health & Reliability: Establish metrics, monitoring, and frameworks to maintain overall system health and reliability for platform software across the wearables portfolio Cross-Functional Collaboration: Work closely with Core OS, hardware, firmware, connectivity, multimedia, and product teams to align technical strategies and resolve dependencies Mentorship & Technical Excellence: Mentor engineers across disciplines, fostering systems thinking and best practices for cross-stack development Documentation & Communication: Communicate platform architecture decisions, integration strategies, and technical trade-offs to stakeholders at all levels clearly and concisely
