Rust Engineer (m/f/d)

Rust EngineerLocation: Remote or Berlin (Office available)At Deepslate, we are building Speech to Speech Voice AI models that sound and act indistinguishably from a human. And we believe everyone should be able to use them.With its endless languages, dialects, accents, subtle intonations, and speech melodies, voice remains a highly complex unsolved frontier.That is exactly why we started Deepslate.Backed by top-tier investors from the Tech and AI sectors, as well as a major German VC fund, we are incredibly well-funded and moving fast.We are building the future of communication.We aren't trying to build another standalone platform; instead, we are the intelligence engine powering countless other applications. Whether it's integrated as a module by a CRM provider, plugged into another Voice AI platform, or directly embedded into an enterprise system by our integration partners, our model is built to work wherever it is needed.Your RoleMany core parts of our model stack are written in Rust. At the heart of it is our inference engine, written entirely in Rust.Your mission is to build and improve these systems. You will work on the inference engine, take ownership of other Rust projects, and help decide how everything fits together. We need someone who enjoys writing good Rust code and can design software that stays understandable and maintainable as it grows.Our models need to respond in real time. The software you build will directly influence how fast and reliable they are in an actual conversation.What You'll DoBuild in Rust: Develop our inference engine and other core components of the model stack. Take projects from the first architectural decisions to running in production.Design the Architecture: Decide how components and services communicate, where responsibilities belong, and how we can extend the system without making it harder to work on.Work on Real-Time Systems: Build async Rust systems that handle concurrent workloads and streaming audio with low latency.
