Backend Engineer

01. ABOUT THE COMPANY

Dizzaract is a product-driven company operating at the intersection of gaming, digital platforms, and AI. We build and scale multiple products, including FAR Labs & Gamed - each exploring a different space, yet united by a shared approach: moving fast, staying curious, and focusing on things that people actually use.

We operate as a collaborative, non-hierarchical team where ideas are valued based on their impact, not their origin, and where AI is embedded across everything we build, from infrastructure to product decisions.

FAR Labs is building a distributed inference platform designed to serve large language models efficiently across diverse hardware. Serving quality - latency, throughput, memory efficiency, cost, and model quality - sits at the core of the product.

We are looking for a
Senior Backend Engineer
to design, build, and scale the backend systems powering FAR Labs products and platforms.

This is a hands-on engineering role with significant technical ownership. You will work across
APIs, distributed services, data systems, authentication, real-time communication, integrations, and production infrastructure
.

You will collaborate closely with AI, infrastructure, frontend, and product engineers to turn complex technical requirements into reliable production systems.

We are looking for someone who goes beyond implementing tickets - someone who understands the broader system, makes thoughtful architectural decisions, identifies technical risks, and takes responsibility for what happens after the code reaches production.
