Senior Product Marketing Manager (Kubernetes Optimization)

Role Description

Kubernetes optimization is Cast AI's core platform and our main competitive battleground. As that surface keeps growing, across the Node Autoscaler, Karpenter Enterprise Suite, and the Workload Autoscaler, we need one person to own the full commercial story.

The core platform is growing fast, faster than our commercial story has kept pace with. That's the opportunity: you'll build the unified narrative this portfolio is ready for, set the launch discipline that keeps it consistent as new features ship, and give sales messaging they can actually reuse instead of rebuilding it deal by deal.

This is a highly technical and strategic role. You'll act as the voice of the product in the market and the voice of the customer internally, which means translating the same product differently for:

• Platform engineers
• DevOps and SRE leaders
• FinOps teams
• VPs of Engineering
• CTOs

That requires real fluency in how software runs, built through marketing technical products, not necessarily through an engineering background. We operate automation-first and market-obsessed, so you're expected to treat customer and market signals as the input behind every decision, and to build AI-assisted workflows that make this function faster and more consistent over time.

You'll report to the Director of Product Marketing, who sets priorities and goals with you, and you'll have real support from:

• Product
• Content
• Demand Gen
• Customer Success
• Design

What success looks like in year one:

• Messaging is consistently adopted across launches and by the sales team, not rebuilt deal by deal.
• Launches land stronger, with measurable product adoption or pipeline impact tied to them.
• Competitive win rates improve, and the field actually uses the competitive materials you build.
• Sales has real confidence in the product narrative, not just access to a deck.
• Customer proof points are quantified, not anecdotal.
• A repeatable customer and win/loss feedback loop exists and demonstrably shapes Product and GTM decisions.

Qualifications

• 5+ years in product marketing, with real experience in cloud infrastructure, Kubernetes, DevOps, developer tools, FinOps, observability, databases, or a similarly technical B2B market.
• Technical fluency. You can talk to engineers and technical audiences without sounding shallow.
• A track record of turning complex technical products into clear, differentiated messaging for both practitioners and executives.
• Excellent writing, backed by work samples such as positioning, launch content, sales narratives, or technical thought leadership.
• Experience leading launches and influencing adoption, pipeline, or competitive outcomes, not just producing launch collateral.
• Experience leading customer, market, or win/loss research that actually changed a product or go-to-market decision.
• Strong cross-functional work with Product, Engineering, Sales, Customer Success, and Growth.
• Comfortable operating without a mature playbook. This function is still being built, and you'll be defining a process as much as executing against one.
• Fluent English, written and spoken.

Requirements

• Owned positioning or GTM for an infrastructure, DevOps, or platform engineering product.
• Background in AI infrastructure, data platforms, or developer tools.
• Used customer and deal evidence to shape product strategy and GTM.
• Evidence of using AI to make your own PMM work faster, more consistent, more reusable, or easier to measure.

Responsibilities

• Own positioning and messaging for the core platform, including narrative input for external moments like webinars, analyst conversations, and industry events, and keep it consistent as new features ship.
• Build messaging that explains the same product differently for platform engineers, DevOps and SRE leaders, FinOps teams, VPs of Engineering, and CTOs.
• Run customer research with core platform buyers to ground positioning in what they actually say, not internal assumptions.
• Translate the technical mechanics behind each core product into a value narrative technical buyers recognize as true the first time they hear it.
• Manage feature launches end to end, from early positioning through GA, coordinating timing with Product and rollout with Sales.
• Build go-to-market plans for core platform releases, including market input to pricing and packaging decisions, and drive plans through execution.
• Own the competitive assets, narrative, and proof points Sales and Customer Success use with customers, backed by win/loss analysis of what's actually winning and losing deals.
• Maintain the feedback loop from customer and market signal back into roadmap input.
• Track competitive dynamics in this category continuously, and act on it by measuring how each launch actually performs and adjusting from there.
• Build and maintain AI-assisted workflows that make this function faster, more consistent, or easier to measure.

Benefits

• Competitive salary (depending on the level of experience).
• Enjoy a flexible, remote-first global environment.
• Collaborate with a global team of cloud experts and innovators, passionate about pushing the boundaries of Kubernetes technology.
• Equity options.
• Get quick feedback with a fast-paced workflow. Most feature projects are completed in 1 to 4 weeks.
• Spend 10% of your work time on personal projects or self-improvement.
• Learning budget for professional and personal development - including access to international conferences and courses that elevate your skills.
• Team-building budget and company events to connect with your colleagues.
• Equipment budget to ensure you have everything you need.
• Extra days off to help maintain a healthy work-life balance.
