Job description

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.
