Director, Social Media & Technical Communications

About Radiant

Radiant is looking for a senior social media and communications leader who can turn deep technical substance into public narrative, executive voice and market momentum.

The right candidate is a high-agency B2B technology storyteller: technically curious, editorially sharp, deeply fluent in social media, and resourceful enough to build a steady pipeline of speaking opportunities, conference submissions, podcast pitches, panels, awards, and executive visibility moments.

You should be comfortable operating in complex technical markets AI infrastructure, GPUs, datacenters, developer platforms, enterprise software or similar categories. You do not need to be an engineer, but you need to be able to sit with technical leaders, understand what matters, find the angle, and translate it into language that is sharp, credible, and useful.

What You’ll Own

Social Media Strategy & Execution

You will own the company’s social presence across executive and corporate channels, with a particular focus on LinkedIn and other platforms where technical buyers, partners, investors, customers, and industry influencers spend time.

You will develop the strategy, write the content, shape the voice, test formats, track performance, and build a social engine that is sharp, intelligent, and distinctive. This includes company posts, executive posts, technical POVs, event coverage, launch support, partner amplification, customer moments, recruiting content, and timely commentary on industry developments.

Executive Voice & Thought Leadership

You will help build and sharpen the public voices of the company’s executives and technical leaders. That means developing points of view, ghostwriting posts, preparing talking points, identifying timely angles, and turning internal conviction into external narrative.

Technical Communications

You will work closely with product marketing, product, engineering, infrastructure, sales, partnerships and leadership to understand what the company is building and why it matters.

You will translate technical topics into clear, compelling communications for the market. This may include short-form social content, executive posts, speaking abstracts, event messaging, award submissions, customer stories, and thought-leadership themes.

You should know how to ask good questions, pressure-test claims, avoid hype, and make technical content accessible without making it shallow.

Speaking, Awards & Opportunity Pipeline

You will build and manage a proactive speaking and visibility engine for the company and its executives.

We expect a consistent weekly motion: sourcing opportunities, drafting abstracts, preparing submissions, pitching panels, finding podcasts, tracking deadlines, managing speaker assets, and creating a calendar of external visibility opportunities.

The expectation is not that every submission turns into a talk. The expectation is that the opportunity pipeline is always moving.

Tools, Analytics & Leverage

You should be fluent with modern marketing, social, research, writing, analytics, AI, design, video, transcript, and workflow tools. We are looking for someone who uses tools to move faster, test more ideas, repurpose better, and increase output quality without adding process drag. You should be comfortable measuring what works, identifying patterns, and improving the system over time.

Who You Are

You have 7–10+ years of experience in B2B technology communications, social media, content, executive communications, PR, thought leadership, or a closely related function.

You have worked in technical markets and can show that you understand how to communicate complex products, platforms, or infrastructure to sophisticated audiences.

You are an exceptional writer with strong editorial judgment.

You are social-native, not social-adjacent. You understand hooks, formats, timing, voice, audience behavior, and what makes technical content travel.

You are deeply resourceful. You do not wait to be handed opportunities. You find them, qualify them, pursue them, and keep the machine moving.

You are creative with language, formats, and tools.

You are commercially aware. You understand that social and communications should support brand, category creation, executive visibility, partner credibility, recruiting, customer confidence, and pipeline influence.

You are highly autonomous. You need direction, context, and access - not constant supervision.

Ideal Background

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

Agency experience can be valuable if you have been hands-on with technical storytelling and executive communications. Big-company experience can be valuable if you have also operated with startup speed and ownership.

What matters most is quality of output, technical curiosity, taste, velocity, and judgment.

• We are looking for someone who can build a communications engine around a complex technical company - someone who can find the story, sharpen the point of view, create the content, and push the company into the right conversations.
