About the role

  • Architect efficient and scalable systems that bridge low-level infrastructure (GPU scheduling, model serving, distributed training) with high-level product surfaces.
  • Work hand-in-hand with Product Managers to translate roadmap priorities into well-scoped technical deliverables, surfacing trade-offs and unblocking ambiguity early.
  • Contribute to technical content (documentation, code samples, blog posts, demos) that helps developers get the most out of RadixArk's products.

Responsibilities

  • Collaborate with cross-functional teams (Product, Design, Research, Infrastructure, Developer Relations) to design and ship developer-facing products on top of RadixArk's inference and training platforms.
  • Build and maintain customer-facing APIs, SDKs, CLIs, dashboards, and playgrounds that expose the power of SGLang, Miles, and our serving infrastructure in intuitive, well-documented interfaces.
  • Implement custom user interfaces and developer experiences using modern frontend and backend technologies, with a high bar for performance, accessibility, and craft.
  • Analyze and optimize code for quality, efficiency, and performance, and provide thoughtful feedback to peers during code reviews.
  • Establish end-to-end ownership of components, features, or systems, from initial design through rollout, monitoring, and iteration.
  • Set direction and goals for product engineering initiatives, lead major launches, and provide technical guidance and mentorship to peers and new team members.
  • Identify and resolve performance, reliability, and scalability issues across the product stack, and drive efforts to reduce technical debt.
  • Participate in design reviews and technical discussions, evaluating trade-offs between system complexity, developer experience, and time-to-ship.
  • Engage directly with early adopters, design partners, and the open-source community to understand pain points and rapidly iterate on product experiences.

Requirements

  • Bachelor's degree in Computer Science, Computer Engineering, a relevant technical field, or equivalent practical experience.
  • Minimum Requirements
  • 5+ years of software engineering experience building production systems, OR 3+ years with a PhD in a relevant field.
  • Strong programming skills in at least one of: Python, TypeScript/JavaScript, Go, C++, or Rust.
  • Demonstrated experience shipping developer-facing or product-facing software end-to-end, including APIs, SDKs, web applications, or developer tools.
  • Experience using data and analysis to explain technical problems, prioritize work, and inform design decisions.

Nice to have

  • Familiarity with LLM inference and training stacks (e.g., SGLang, vLLM, TensorRT-LLM, PyTorch, Megatron, DeepSpeed, Ray) and the trade-offs involved in serving and training large models.
  • Experience contributing to or maintaining open-source projects, especially in the AI/ML or infrastructure ecosystem.
  • Experience improving quality through code reviews, testing, careful rollout, monitoring, and proactive iteration.
  • Experience working in B2B, developer-facing, or infrastructure product environments.

Skills

  • Excellent collaboration and communication skills, with a track record of driving complex technical projects across teams.
