# Business Development at RadixArk

- **Company:** RadixArk
- **Location:** Palo Alto, CA
- **Posted:** 2026-05-26
- **Last confirmed live:** 2026-09-06
- **Apply:** https://job-boards.greenhouse.io/radixark/jobs/4258540009

## Job description

## 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.

## What You'll Own

## Team Building

- Hire and develop a BD team; establish the culture, methodology, and cadence for maintaining customer relationships at scale
- Define the norms for how the BD team operates — how we track, how we communicate, how we escalate
- Own the BD team's contribution to our single source of truth: the shared tracking sheet used by both BD and Adoption

Relationship Coverage

- Maintain broad, active relationships across our full customer surface: early adopters, shallow contacts, and gated prospects we haven't yet engaged deeply
- Design and run regular check-in rhythms (watching channels) that give us continuous pulse on the market without requiring deep-dive bandwidth from the full team
- Provide genuine relational continuity for customers when the Adoption team doesn't have capacity — not just placeholder outreach, but real emotional presence

Downstream Handoff

- Identify customers who are ready for deeper engagement and hand them off cleanly to the Adoption team — with full context, no gaps
- Ensure raw data on gated customers remains accessible and well-documented so the Adoption team can run market research without starting from zero

Strategy & Intelligence

- Serve as the alert system for the company: surface important signals — bad news, emerging trends, inflection points — before they become surprises
- Synthesize BD observations into regular summaries and analyses that inform commercial strategy and resource allocation
- Own the bidirectional feedback loop between the BD team and the Adoption team — make sure learning flows both ways
- Provide guidance on where the company should invest engagement resources and where to pull back

Strategic Partnerships

- Lead partnership development with industry leaders, regional leaders, and category leaders or rising stars in the AI infrastructure ecosystem
- Own the full partnership lifecycle from prospecting to structuring to activation

## 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
