Job Description

About OSec

OSec is an offensive security firm built for the midmarket. We help organizations understand not just where they're exposed, but what's actually at risk and what to fix first. Through our security services and Incenter, our continuous threat exposure management platform, we deliver the combination of practitioner expertise and continuous visibility that automated tools alone can't provide.

The Opportunity

We're a lean team. Everyone here does real work. This means you will be the marketing department, not just a supporting player.

You'll work directly with our Fractional CMO and CEO to own campaign execution, drive pipeline, and build the operational foundation that makes consistent marketing possible.

The strategic foundation is in place: positioning, messaging, competitive differentiation, and content infrastructure. What we need now is someone who is accountable to outcomes - campaigns that run on time, leads that move through the funnel, and programs that compound. You'll use HubSpot as your execution engine, but pipeline is how we'll measure success.

What You'll Do

Campaign Execution & Demand Generation

• Own and execute integrated, multi-channel campaigns from brief through reporting: email, content, social, and paid; with clear KPIs and targets for each program
• Execute quarterly sector-themed campaigns: building the audience, coordinating assets, launching the program, and reporting on what moved the needle
• Build and manage lead database growth programs: list development and acquisition, contact enrichment, and net-new audience development to support campaign scale
• Support and optimize sales sequences in coordination with the business development team, ensuring leads are followed up consistently and on time
• Manage the content calendar and maintain a consistent publishing cadence across blog, email, and social

Marketing Operations & HubSpot

• Build and maintain suppression logic, send calendars, and enrollment workflows to protect deliverability and prevent list fatigue
• Track and report on campaign performance: open rates, CTR, pipeline influence, and lead velocity - and bring that data to the table proactively
• Manage the marketing tech stack and flag consolidation or integration opportunities as the program scales
• Own HubSpot as the execution engine: database hygiene, segmentation, list management, workflow builds, and campaign deployment

Webinars & Events

• Own end-to-end webinar execution for OSec programs: platform setup, registration pages, speaker coordination, promotion, live logistics, and post-event follow-up sequences
• Build and manage event promotion campaigns: email invitations, landing pages, reminder sequences, and social promotion to maximize registration and attendance
• Coordinate industry event participation as needed: conference logistics, booth materials, pre/post-event email campaigns, and on-site support coordination
• Track attendee engagement and feed qualified registrants into HubSpot workflows for appropriate nurture or sales follow-up
• When needed, repurpose webinar and event content into additional marketing assets (recap blog posts, clips, email follow-ups, and social content) to extend the value of each program

Partner & Channel Marketing Support

• Support execution of partner co-marketing programs: coordinating timelines, deliverables, and approvals for OSec
• Execute joint campaigns to partner lists as needed, including HubSpot setup, segmentation, send coordination, and post-send reporting
• Support maintenance of partner-facing content library: help to keep materials current, on-brand, and easy for partners to find and use
• Support tracking of partner campaign performance and surface insights that help inform which relationships and program types are generating real pipeline value

Brand & Thought Leadership Support

• Maintain brand consistency across all marketing touch points (web, email, social, and sales collateral) and provide light support for executive visibility and PR coordination as needed

What We're Looking For

Must-Have

• 5+ years of B2B marketing experience with demonstrated ownership of campaigns and pipeline, not just supporting someone else's programs, but running them
• Proficient HubSpot user - you can build workflows, manage lists, segment audiences, and pull meaningful reports. You don't need to be a HubSpot specialist, but you need to be self-sufficient and able to learn more ways to supercharge your HubSpot usage
• Operationally wired - you build systems, maintain them, and hold yourself accountable to deadlines and metrics
• Strong editorial judgment - you don't need to be a great writer, but you need to recognize good writing, know when AI output needs work, and publish content you'd stand behind
• Comfortable working independently in an early-stage environment where ambiguity is the norm and structure is something you help create
• Enough cybersecurity fluency to engage credibly with the content - you don't need to be a practitioner, but you can't be starting from zero

Nice-to-Have

• Experience working with AI tools and developing workflows for marketing
• Familiarity with offensive security concepts, security services, etc.
• Hands-on experience running webinars and events end-to-end - from platform setup and promotion through post-event nurture
• Background in a startup or early-stage company where you built programs from scratch
• Exposure to ABM strategy or intent-data-driven campaign targeting

What We Value

• Continuous learning: cybersecurity moves fast, but AI is making things move even faster. Curiosity is a core competency here.
• Ownership and initiative: you see a gap, you fill it. You don't wait to be assigned.
• Collaboration: marketing doesn't win alone. You'll work closely with sales, leadership, and partners.
• Intellectual honesty: if something isn't working, say so. We make better decisions with real data.
