About the Role
Meta is seeking a Software Engineer to build and scale product experiences used by billions of people across Meta's family of apps and platforms. In this role, you will own the design and delivery of complex product features end-to-end, partnering closely with product management, design, data science, and infrastructure teams to ship high-quality, reliable software. You will bring both technical depth and product thinking to your work, driving engineering decisions that directly improve user outcomes and advance the team's roadmap.

Key responsibilities include building product-grade applications and games that exceed core experience expectations, producing high-fidelity, responsive, and fluid experiences across devices, and developing software that adapts to resource constraints at runtime such as GPU, CPU, memory, I/O, networking, and thermal conditions. You will integrate with operating system and system services applications rely on, including connectivity, notifications, and security.

Additionally, you will build features, applications, services, systems, and games that improve model capabilities and generate high-value training data. You will work across teams to drive projects and initiatives that enhance the quality and value of evaluation and training data. This role requires establishing yourself as the owner of a particular area or system with expert end-to-end understanding.

Experience
- Deep experience in optimizing applications where system or hardware optimization is essential, such as time-sensitive applications, real-time data, or render loops
- Experience with popular mobile and graphics performance tracing and profiling tools, including RenderDoc and Perfetto
- Relevant experience in building and shipping games, applications, or interactive experiences to production
- Experience with performance optimization and working within resource constraints such as CPU/GPU, memory, thermal, and networking
- Experience integrating applications with platforms or operating system services
- Programming experience in relevant languages such as C++, C#, Python, or shaders
- Experience as an owner of a particular component, feature, or system
- Experience building developer-facing tooling, SDKs, or frameworks
- Experience shipping across multiple platforms including mobile, desktop, console, web, or wearables
- Exposure to large language model or generative AI application development, evaluation, design, or data generation for model training
- Experience with game engine technology such as Unity or Unreal, or with real-time graphics
- Exposure to architectural patterns of large-scale software applications

About you
You demonstrate strong technical depth combined with product thinking and a passion for delivering high-quality software that improves user outcomes. You are collaborative and able to work closely with cross-functional teams including product management, design, data science, and infrastructure. You have a demonstrated interest in AI models and their applications to software development and are motivated to drive engineering decisions that advance the team’s roadmap.

Qualifications
Bachelor's degree in Computer Science, Computer Engineering, a relevant technical field, or equivalent practical experience.
