About the role

We're looking for a Technical Product Marketing Manager to own how developers discover, adopt, and grow with Phoenix and the broader Arize developer ecosystem.

Phoenix is often the first touchpoint developers have with Arize. This role owns that experience end-to-end - from discovery to first use to sustained adoption and growth. You'll help shape the product experience, remove friction, and expand Phoenix's reach, usage, and developer mindshare.

This role sits at the intersection of product marketing, developer experience, and open-source growth. You'll combine technical fluency, strong narrative instincts, and a bias to ship to drive measurable improvements in developer activation, engagement, and expansion.
What you'll do
Own the developer growth motion

• Define and own key metrics across the developer journey: awareness, adoption, activation, engagement, and qualified conversion signals from Phoenix into AX where relevant
• Identify friction across the OSS, cloud, and self-serve experience, and partner with product to improve it
• Develop hypotheses and run experiments to improve onboarding, activation, engagement, and expansion

Narrative & positioning

• Own messaging and positioning for Phoenix and self-serve AX
• Clarify Phoenix's role in the AI evaluation, observability, and agent development ecosystem
• Help articulate how Phoenix and Arize AX fit together for different audiences and stages of adoption
• Support launch coordination for major Phoenix releases

Developer journey & content

• Build technical content that supports key moments in the developer journey (first use, activation, production readiness)
• Create and improve onboarding and activation flows across OSS, cloud, and self-serve experiences
• Develop guides that show how Phoenix is used in real-world workflows, and how teams can extend those workflows into AX when needed
• Write from hands-on product usage and real technical understanding.

Community & ecosystem

• Engage with the Phoenix and broader AI developer community to understand needs and surface insights
• Partner with DevRel on amplification and community engagement
• Identify which channels and communities are worth investing in, and help shape Arize's developer community strategy
• Identify opportunities to grow Phoenix's reach and mindshare

AI-Native Execution

• Use AI-native workflows to monitor ecosystem signals, synthesize feedback, and ship quickly
• Dogfood Arize products in your own workflows and write from direct experience
• Operate with a strong bias toward iteration, experimentation, and measurable outcomes

What we're looking for

• 3-5 years in developer marketing, product marketing, developer relations, or a technical/product role with strong go-to-market instincts
• Comfortable reading and working with code, APIs, and developer tools
• Strong technical writing skills
• Experience with AI/ML tooling, observability, or developer workflows
• Comfortable using AI tools as part of daily workflows
• Hands-on executor who ships fast
• SF-based

Bonus points

• • Experience with OSS go-to-market or PLG
  • Existing relationships in the SF AI community
  • Personal following in AI/ML

Pay Range $140,000-$175,000 depending on experience
