About the role
About
the Role 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. Key
Responsibilities Product Positioning & Messaging: Own product positioning and messaging for SGLang, Miles, and the broader platform. Build and maintain buyer personas and ideal customer profiles to guide segmentation and storytelling. Translate complex technical capabilities such as inference optimization and RL post-training into clear, differentiated value for distinct audiences. Partner with engineering and product to turn new releases and features into market-ready narrative as soon as they ship. Go-to-Market & Launches: Own the go-to-market strategy and launch calendar for new products and major updates, coordinating the cross-functional work needed to land them. Produce sales and partner enablement assets including pitch decks, battlecards, case studies, and benchmark narratives. Ensure consistent messaging across every touchpoint, from website and social to partner co-marketing and events. Field Events & Activations: Plan and execute RadixArk's field programs end to end, including developer meetups, partner activations, and industry conference presence. Own agenda, speakers, vendors, on-site execution, and post-event follow-up, not just the brief. Because the messaging originates with you, you keep the content and the experience aligned, and you tie each program back to community growth, adoption, and pipeline. External Communications & Issue Response: Shape RadixArk's external voice across announcements, statements, and executive-facing narrative. Build relationships with media, analysts, and technical influencers. When sensitive situations arise, such as a partner omitting our contribution from their messaging, a contested benchmark, or a community controversy, assess quickly whether and how to respond, set the right framing and channel, and write the response yourself.
