About The Role

We're looking for a Head of Business Development to build the BD function at RadixArk from the ground up. The BD team is the institutional memory of this company — maintaining active relationships across every customer we've touched, detecting signals early, and ensuring nothing falls through the cracks. You'll design the system, build the team, and run it.

The role is equal parts relationship and rigor. You'll hold the relationship thread across a broad customer surface while tracking coverage rates, handoff volume, signal trends, and engagement quality — and translating that into clear intelligence for the broader commercial organization. We move fast, operate with a sense of urgency, and expect the same from everyone on the team.

Who You Are

Available for a in-office schedule with 5 days per week onsite at our Palo Alto office 10+ years of BD, sales, or partnerships experience, with meaningful time at a high-growth technology company Proven track record building teams and systems from scratch — you know what it means to create culture and methodology, not just inherit it Deeply organized and systems-oriented: you think in coverage maps, tracking layers, and signal structures Strong commercial instincts — you know which customers matter most and how to prioritize attention accordingly Excellent communicator who builds genuine relationships, not just transactional touchpoints Comfortable operating at every level: you'll set strategy and do the outreach in the same week Low ego, high output — you do what it takes to keep the relationship surface warm and the team informed Experience in developer tools, infrastructure, or deep tech is a strong plus About RadixArk RadixArk is an infrastructure-first company built by engineers who've shipped production AI systems, created SGLang (20K+ GitHub stars, the fastest open LLM serving engine), and developed Miles (our large-scale RL framework).
