Senior Software Engineer (Backend / Infrastructure) at Meta
Building backend infrastructure for Horizon OS media, including ingestion pipelines and AI-powered discovery services at Meta.
Intro
I'm Aritra Sen, a Senior Software Engineer at Meta currently focused on backend and infrastructure for Horizon OS within Reality Labs. My career has been defined by building high-scale systems, from optimizing Android's Bluetooth stack at Google to developing real-time communication pipelines. I'm deeply passionate about system design and infrastructure reliability—essentially, I love figuring out how systems behave under real-world load and ensuring they are built to last. Beyond my day job, I enjoy teaching system design, sharing interview strategies for MAANG companies, and playing chess. I’m always happy to offer guidance on navigating the tech industry or to dive deep into technical discussions about distributed systems. I'm here to connect with fellow engineers and builders who value genuine professional exchange over generic networking.

Opinions
- DSA should not be the exclusive metric for judging experienced engineers
- Dislikes 'spammy' LinkedIn content like generic notes or PPTs
- Prioritizes reliability, latency, and leaving systems better than they were found
- Job referrals are a numbers game; candidates should not shy away from asking
