From RadixArk's posting. “We” and “our” refer to the employer.
RadixArk is seeking a Product Marketing Manager to own how SGLang, Miles, and our open source infrastructure are positioned and perceived across the market. SGLang already has 20K+ GitHub stars and serves billions of tokens daily across leading AI companies and research labs, and we're looking for someone to be the bridge between our engineering team and the people who decide to adopt, partner with, and write about us.
You'll define our product messaging, drive our launch calendar, and translate deeply technical systems into value that developers, partners, and buyers understand. You'll also bring that messaging to life in person by running our field events, and you'll be the steady hand who shapes our external response when something needs a clear public voice. This role combines product marketing depth with hands-on execution, and you'll have real influence over how our products are positioned and adopted across the AI infrastructure community.
RadixArk is an infrastructure-first company built by engineers who've shipped production AI systems, created SGLang (30K+ GitHub stars, the fastest open LLM serving engine), and developed Miles (our large-scale RL framework). Founded by AI infrastructure veterans from xAI and NVIDIA, we're on a mission to democratize frontier-level AI 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 AI companies and research labs.
Compensation
Depending on background, skills, and experience, the expected annual salary range for this position is $160,000 - $300,000 USD + equity.
Equal Opportunity
RadixArk is an Equal Opportunity Employer and is proud to offer equal employment opportunity to everyone regardless of race, color, ancestry, religion, sex, national origin, sexual orientation, age, citizenship, marital status, disability, gender identity, veteran status, and more.
