Job description

Full Stack Engineer

Palo Alto, CA

About The Role

RadixArk is building the infrastructure layer for frontier AI systems — unified inference, training, and evaluation stacks powering next-generation LLM applications at scale. Our platform integrates high-performance model serving, RL pipelines, and large-scale distributed systems across GPUs, TPUs, and emerging accelerators. We work at the intersection of systems engineering, AI research, and developer experience. We are looking for a world-class Full Stack Engineer who thrives in high-ambiguity environments and wants to build foundational tools for the next decade of AI.

Requirements

Technical Excellence

  • 4+ years of professional full stack engineering experience
  • Based in Palo Alto, CA (Hybrid) / Remote (U.S.)
  • Deep experience in:
    • Frontend: React / Next.js / TypeScript
    • Backend: Python (FastAPI / Django) or Node.js
    • RESTful and/or gRPC API design
  • Strong understanding of distributed systems concepts
  • Experience building systems that handle real-time streaming or high-throughput workloads
  • Strong database design skills (Postgres, Redis, etc.)
  • Familiarity with containerized environments (Docker, Kubernetes)
  • Strong software engineering fundamentals: testing, CI/CD, version control, design reviews
Bonus (High Impact)
  • Experience building developer tools or infrastructure platforms
  • Experience in ML infrastructure, model serving, or AI tooling
  • Familiarity with observability stacks (Prometheus, Grafana, OpenTelemetry)
  • Experience with WebSockets or streaming architectures
  • Performance optimization at scale
  • Experience building internal platforms used by engineers
Responsibilities

You will own end-to-end product surfaces across our developer platform:

  • Design and implement high-performance web applications for AI infrastructure tooling
  • Build scalable backend systems that interact with distributed inference and training services
  • Architect APIs and service layers that serve enterprise and research customers
  • Develop observability dashboards, experiment tracking UIs, and performance analytics tools
  • Optimize real-time streaming interfaces for model inference workflows
  • Work closely with ML engineers and infra teams to expose complex systems through intuitive product surfaces
  • Lead architectural decisions for frontend-backend communication, state management, and performance tuning
  • Ship production-grade features in fast iteration cycles

You will not just "write UI." You will build the control plane for frontier AI systems.

Your work will directly power:

  • Large-scale LLM inference systems
  • Reinforcement learning training platforms
  • Evaluation and experimentation frameworks
  • Developer-facing AI infrastructure products

This is not CRUD dashboard engineering. This is building the operating system for AI builders.

About RadixArk

RadixArk is an infrastructure-first company built by engineers who've shipped production Al systems, created SGLang (20K+ GitHub stars, the fastest open LLM serving engine), and developed Miles (our large-scale RL framework). We're on a mission to democratize frontier-level Al infrastructure by building world-class open systems for inference and training. Our team has optimized kernels serving billions of tokens daily, designed distributed training systems coordinating 10,000+ GPUs, and contributed to infrastructure that powers leading Al companies and research labs. We're backed by well-known infrastructure investors and partner with NVIDIA, Google, AWS, and frontier Al labs. Join us in building infrastructure that gives real leverage back to the Al community.
