Job Description

About PubNub

At PubNub, we power real-time experiences used by millions of people around the world. Our platform enables businesses to build real-time applications through developer-friendly APIs and real-time infrastructure.

PubNub powers the world's most engaging real-time experiences—including chat, live updates, and interactive applications—for more than 2,000 companies, including Verizon, Autodesk, Zillow, and Dropbox. Our global data network processes trillions of messages each month with sub-100 ms latency across 15+ data centers. Backed by $130M in funding, we're shaping the future of how the world connects.

About the Role

At PubNub, customer growth is a key part of our go-to-market strategy. As our Customer Lifecycle Marketing Manager, you'll own the marketing programs that help customers adopt more of our platform, realize greater value, expand their usage, and stay engaged throughout their journey.

You'll lead lifecycle marketing initiatives focused on customer health, expansion, and churn prevention, working closely with Customer Success and Account Managers. Success in this role means improving Net Revenue Retention (NRR), reducing preventable customer losses, and creating a steady stream of expansion opportunities from our existing customer base.

If you enjoy turning customer usage data into relevant, well-timed marketing programs and want ownership of a metric the whole company watches, this is a high-impact opportunity with significant ownership and room to grow.

Key Responsibilities

• Build customer lifecycle and nurture programs distinct from prospect marketing.
• Design platform expansion campaigns based on onboarding use cases and unused features.
• Partner with Go-to-Market Engineering (GTME) on customer health scoring and expansion signal detection.
• Create ROI reports and value summaries as easy, one-click artifacts Account Managers can use in-deal.
• Run multi-team penetration plays within existing enterprise accounts.
• Build win-back and re-engagement campaigns for quiet or at-risk customers.
• Analyze why customers leave and turn insights into retention plays.
• Partner closely with Customer Success and Account Managers on retention initiatives.

About You

• Hands-on experience in developer marketing, technical marketing, developer relations, product marketing for a technical product, or a closely related role.
• Strong technical fluency: you can understand APIs, SDKs, AI development workflows, and code examples well enough to communicate accurately and participate credibly in developer communities.
• A track record of creating and distributing technical content or campaigns that moved developers from awareness to hands-on product use.
• Strong track record of using quantitative analytics and experimentation frameworks to drive growth and improve performance across the developer funnel.
• A community-minded, collaborative approach. You listen well, contribute with authenticity, and are comfortable working across Product, Growth, Engineering, and Developer Relations.

Nice to Have

• Familiarity with AI application development, agents, LLM tooling, or adjacent developer ecosystems.
• Ability to use AI-assisted development tools to prototype simple demos, landing-page experiences, examples, or other technical marketing assets.

Why Join Blocks.ai

Because Blocks.ai is built by PubNub, you’ll combine the pace and ownership of a new venture with proven global infrastructure and an experienced team behind it.

As a remote-first company, we value flexibility, collaboration, and continuous learning. You'll work alongside talented colleagues who are passionate about solving complex problems and delivering meaningful impact for our customers.

We offer a B2B engagement with monthly compensation ranging from PLN 12,000 to PLN 18,000, along with benefits that support your success and well-being, where applicable.
