The opportunity

We build and run the inference engine behind every Perplexity query and deploy dozens of model architectures at scale with tight latency and cost budgets. Our stack is Rust, Python, CUDA, and CuTe DSL - and we need another engineer to join us.

What they're looking for

  • You understand modern LLM architectures and are able to bring them up reliably in a production environment.
  • You've built and operated production distributed systems under real load - ideally performance-critical ones.
  • Comfortable working across languages and layers: Rust for the serving runtime, Python for model code, CUDA/CuteDSL for kernels.
  • You own problems end-to-end. You can read a research paper on Monday, write a: kernel on Wednesday, and debug a production incident on Friday.
