Compiler Engineer

About Ubitium

Ubitium is developing the universal RISC-V processor — a revolutionary step toward transforming the computing landscape. Our universal processor architecture is entirely workload-agnostic, reusing the same transistors for all types of workloads. Unlike traditional processors that rely on specialized cores, our solution results in processors that are smaller, more energy-efficient, and significantly more cost-effective across a broad spectrum of applications.

Ubitium’s universal processor can run massive parallel signal chains, AI, and operating systems side-by-side — on a unified processing and memory fabric. With deterministic scheduling, hardware multithreading, and SIMD/MIMD/SIMT execution models, we keep pipelines hot and eliminate expensive data hops between separate chips. This architecture is ideal for:

• Beamforming
• Control loops
• Multi-channel audio
• Lidar, radar, and vision systems
• Inference-in-the-loop workloads

If you’re passionate about innovation and shaping an AI-enabled future, Ubitium offers a unique ground-floor opportunity you won’t want to miss!
