Job description

Hybrid - Edison, New Jersey, United States

Jul 28, 2026

About the Role:

1Kosmos is the leader in unifying identity proofing and passwordless authentication for enterprises, providing a trust platform for financial institutions, healthcare organizations, retailers, and government agencies.

We're a fast-growing team looking for a B2B social media strategist and content writer hybrid who can own our social presence end to end. This is the single accountable owner for all things social at 1Kosmos, spanning four surfaces: our company channels, our executives' personal presence, our employee advocacy program, and our relationships with external influencers and advocates. You'll sit on a growing content marketing team, working closely with our Content Marketing Manager and Brand and Digital Director to build a social presence that both strengthens our brand and drives pipeline.

You'll drive strategy, write copy, manage a consistent content calendar, direct visual production, and transform events and people into sustained brand momentum — before, during, and after. Primary channels include LinkedIn, YouTube, and X.

What You'll Do:

You'll own all four layers of our social presence: company channels, executive personal brands, employee advocacy, and external influencer/advocate relationships as the single accountable owner. Specifically, you'll:

Own social strategy and execution across LinkedIn (primary), YouTube, X, and emerging channels, setting the calendar and cadence rather than reacting to one-offs

Run an employee advocacy program for executives and ~15–20 customer-facing employees: ghostwrite, coach, and equip people to post in their own voices to multiply reach

Build and manage relationships with external voices — industry influencers, analysts, customer advocates, and partners — to extend reach and credibility, coordinating both sponsored and organic amplification

Write on-brand copy for social posts, graphics, and thought leadership content with precision and voice consistency

Produce and direct visual content on-site, either hands-on or by managing freelance photo/video resources, and hold a high quality bar

Ship executive and customer video series on a consistent, reliable schedule

Build a repeatable event content playbook: hype before, live coverage during, thought-leadership follow-up after, making 1Kosmos's presence at flagship events feel bigger than life

Contribute to omnichannel campaigns spanning social, paid, and email

Monitor the market: competitors, customers, and trends in identity security and AI; know the buyer (CISOs, security and IT leaders) well enough to make content land

Measure KPIs such as reach, engagement, branded search lift, share of voice, and social's contribution to brand and pipeline

What You Bring:

4–6+ years in B2B social media, content, or brand, ideally in enterprise SaaS, cybersecurity, or another technical, considered-purchase category

A portfolio that includes campaigns, event coverage, or programs where you measurably moved engagement, reach, or brand awareness

Strong writing across multiple voices: you can sound like a CISO one minute and the company the next

Aesthetic and visual taste: you can produce content or manage those who do, and hold a high bar on quality

LinkedIn organic fluency, plus working knowledge of paid social and how organic and demand gen reinforce each other

Self-starter mentality: able to own a function, set strategy, and execute as the single accountable owner

Tool proficiency: Sprout Social / Ayrshare, HubSpot, Wrike, Notion, Adobe Creative Suite, and core B2B social platforms

Nice to Have:

Experience launching or scaling an employee advocacy program

Experience building or running an influencer/advocate program

Background in identity, cybersecurity, fintech, or selling to financial institutions

Familiarity with AI content and social tooling

Experience tying social efforts back to pipeline metrics
