Director, Technical Product Marketing

About the Role

Radiant is looking for a Director of Technical Product Marketing to turn our technical advantages into clear, credible, market-facing narratives.

This is an embedded role for someone who wants to be close to the product, close to engineering, and close to the real substance of what we are building - end to end datacenters. You will spend time with infrastructure, product, engineering, solutions, partnerships, and the leadership team to understand how Radiant works, why it matters, and how to explain it to sophisticated technical and business audiences.

We are looking for someone who can extract the technical truth from the building, understand what is differentiated, and turn that into blogs, web pages, whitepapers, case studies, executive thought leadership, speaking narratives, and product storytelling. This is not a conventional PMM role centered only on launch checklists, personas, and sales decks. Our audience is hyperfocused and well understood. Nor is it a technical writing role.

The right person is technically curious, commercially sharp, and an exceptional writer. Ideally they have coding experience or Claude code experience. They know how to sit with engineers, ask good questions, pressure-test claims, and translate complex infrastructure into language that is accurate, compelling, and useful.

What You’ll Own

Technical Product Narrative

You will own the development of Radiant’s technical product narrative across our platform, infrastructure, and market-facing offerings.

You will work with product and engineering teams to understand what we are building, how it works, what problems it solves, and why it is different. You will translate that understanding into clear positioning, messaging, product explanations, and technical narratives for customers, partners, analysts, executives, and the broader market.

You should think along the lines of: Why did we build this this way? What breaks at scale? What tradeoff did we avoid? What is genuinely differentiated? What should a technical buyer care about? What is defensible?

Technical Content & Thought Leadership

You will create the core technical content that gives Radiant’s hyperscaler end customers confidence that we are who they should trust.

This includes technical blog posts, product pages, solution pages, whitepapers, reference architecture content, case studies, customer stories, launch narratives, technical explainers, executive essays, and long-form thought leadership.

Your job is to make complex topics understandable without making them simplistic. You should be able to write for technical buyers, business decision-makers, partners, investors, and industry observers - adjusting the level of detail without losing credibility.

Web & Product Copy

You will help shape the language on Radiant’s website and product pages.

That means turning internal product reality into strong external copy: what the product does, who it is for, why it matters, how it is different, and what proof points support the claim.

You will work with design, web, product, and marketing teams to create pages that are clear, technically grounded, and commercially useful.

Speaking & Executive Substance

You will support Radiant’s speaking and executive communications efforts by creating the technical spine behind talks, panels, submissions, keynotes, podcasts, executive posts, and strategic narratives.

The social and communications team may own the opportunity pipeline and distribution cadence. Your role is to provide the substance: the thesis, the architecture, the proof points, the technical argument, the story arc, and the language that makes the opportunity credible.

You will also ghostwrite for corporate and executive voices when the content requires technical depth, product understanding, or strategic market framing.

This role will also be public facing and it is our expectation the successful candidate will be an excellent communicator.

Case Studies, Customer Stories & Proof Points

You will help build Radiant’s library of customer, partner, and product proof.

That includes working with sales, solutions, customer teams, and leadership to identify strong stories, extract the technical and business value, and turn those stories into case studies, web copy, blogs, presentations, and sales-supporting narratives.

You will be expected to find the real story behind the account: what problem existed, what was deployed, what changed, what was hard, what mattered, and what the market should learn from it.

Internal Translation

You will act as a bridge between engineering, product, sales, marketing, and leadership.

Engineers should trust you because you ask good questions and represent the technology accurately. Marketing should trust you because you can turn complex ideas into clear, compelling language. Sales should trust you because your work helps customers understand why Radiant matters.

What Success Looks Like

In the first 90 days, you will have built strong working relationships with product and engineering, developed a clear understanding of Radiant’s technical architecture and product priorities, and shipped a meaningful set of market-facing assets.

You will have created a repeatable process for extracting technical stories from the organization and turning them into blogs, web copy, technical narratives, executive content, speaking inputs, and longer-form assets.

Over time, success means Radiant has a deeper, sharper, more technically credible voice in the market. The website explains the product more clearly, our blogs are technical and differentiated.

Who You Are

• You have 8 - 12+ years of experience in technical product marketing, product marketing, technical content, developer marketing, infrastructure marketing, solutions marketing, or a closely related role.

• You have worked in technical B2B markets such as cloud infrastructure, AI infrastructure, developer platforms, data infrastructure, datacenters, enterprise software, or high-performance computing.

• You are an excellent writer. You can write product pages, blogs, whitepapers, case studies, executive essays, launch narratives, and technical explainers with minimal handholding.

• You are technically fluent enough to work directly with product managers, engineers, architects, and technical executives. You do not need to be an engineer, but you need to understand complex systems, ask precise questions, and identify what matters.

• You have strong product judgment. You can distinguish a feature from a benefit, a claim from a proof point, a capability from a differentiated position, and a generic market trend from a useful point of view.

• You are comfortable working in the building. This role requires proximity to the teams building the product. Regular face time with product, engineering, and leadership is part of the job.

• You are highly autonomous. You do not wait for perfect briefs. You find the right people, ask the right questions, create the draft, pressure-test the claims, and move the work forward.

• You have strong editorial taste. You know when copy is too generic, too inflated, too shallow, or too complicated. You can make technical content sharper without making it flashy or imprecise.

• You are commercially aware. You understand that technical marketing exists to help the market understand the company, help customers evaluate the product, help sales tell the story, help executives communicate with clarity, and help the company build credibility.

Ideal Background

The strongest candidates may come from high-growth B2B technology companies, AI infrastructure companies, cloud platforms, developer tools companies, cybersecurity companies, data infrastructure companies, telecom infrastructure businesses, semiconductor ecosystems, or technical agencies with deep infrastructure experience.

Experience working with engineers, architects, product leaders, founders, or technical executives is strongly preferred.

Experience writing about complex technical topics for external audiences is required.

Experience with AI, GPUs, Kubernetes, networking, datacenter infrastructure, cloud platforms, MLOps, sovereign AI, or enterprise infrastructure is a major plus.
