About the Role

This role exists because our most strategic accounts deserve marketing built specifically for them, not a scaled-down version of what we run everywhere else. You'll own account-based marketing for a curated set of top-tier prospects, partnering directly with the strategic sales team to open doors, build momentum, and drive pipeline inside the accounts that matter most. You'll orchestrate multi-channel plays across email, LinkedIn, direct mail, events, and whatever creative idea earns a response from a hard-to-reach buyer. This is a hands-on, build-it role. The list is small, the stakes are high, and we need someone hungry enough to do the unscalable things that actually move a strategic account.

Responsibilities

Own account-based marketing for a curated set of strategic, top-tier prospects, working as a true partner to the strategic sales reps who cover them
Build and run multi-channel account plays across email (Instantly), LinkedIn (HeyReach), direct mail, events, and creative one-off tactics tailored to individual accounts
Turn Harmonic's story, deep AI usage intelligence with the guardrails enterprises need, into messaging that lands with senior security and business buyers
Partner with sales on account selection, contact mapping, and the plays most likely to open and advance each account
Plan and execute events, dinners, and field activities that get strategic buyers in the room
Design and ship direct mail and physical touchpoints that break through where digital can't
Track engagement and pipeline impact at the account level, and double down on what works
Bring new creative ideas to the table constantly, and test them fast

Requirements

1-5 years of B2B marketing experience, ideally account-based marketing, demand gen, or field marketing in a startup or high-growth environment
Hunger. You're proactive, resourceful, and you'd rather try five things this week than wait for the perfect plan
Hands-on experience running outbound and multi-channel campaigns, and comfort in tools like Instantly, HeyReach, or similar
A genuine partnership instinct with sales, you see reps as teammates, not internal customers
Sharp writing and messaging judgment: you can take a technical story and make it land with a busy executive
Creativity and a bias for action, especially the unscalable, memorable tactics that win strategic accounts
An AI-native mindset: you use AI tools to move faster and you're actively experimenting with what's next
Experience marketing to enterprise or Fortune 500/Fortune 10 accounts
Event and field marketing experience, from dinners to conferences
Direct mail or creative physical campaign experience
Familiarity with cybersecurity, AI, or another technical category
HubSpot or similar CRM/marketing platform fluency
Treat a named list of accounts like it's your own business to win
Get restless when a strategic account goes quiet, and do something creative about it
Would rather send a handwritten note and a thoughtful gift than one more email blast
Love working shoulder to shoulder with sales and measuring yourself on pipeline, not activity
Find ambiguity energising: you're good at figuring out what should exist and making it exist
Are actively building with AI tools, not waiting to see where things land
Bring ideas no one asked for, then go run the experiment

About the Company

AI doesn't run in one place anymore. It runs in the browser tab, the desktop app, the agent your engineers kicked off, and the copilot embedded in the tools you already pay for. Harmonic Security governs all of it.
Our AI Governance and Control (AIGC) platform sits on the device, inside the interaction, at the moment of action, reading what AI is actually doing (not just the traffic around it) and acting in under 200ms. Security teams get full visibility and control across every AI surface, including the agentic and MCP layer that traditional tools can't see. Their people get to innovate without guardrails slowing them down.
We're gaining serious traction at the intersection of AI and cybersecurity, and backed by investors who know the space: N47, Ten Eleven Ventures, and In-Q-Tel. As AI adoption inside the enterprise accelerates, the ability to safely observe, control, and enforce policy in real time isn't a nice-to-have. It's mission-critical infrastructure. That's what we build.
Harmonic exists to help enterprises adopt AI safely and at scale. We hold ourselves to that same standard. Everyone here actively uses AI tools to do their best work, from research and writing to building automated workflows. We expect every new hire to bring genuine curiosity for AI and a commitment to working smarter and faster with it.
For some, this means staying open to new tools. For others, it means architecting new systems with AI at the core. We're transparent about expectations for every role, and we give you the tools and support to thrive.
This isn't just a job, it's a chance to help define a category, and to build this chapter of the story from its first page. We're building at the intersection of AI and security, where the rules haven't been written yet, and the people who join now will write them.
Recognized momentum: named to Rising in Cyber 2026, a signal the market is taking notice
Rare market opportunity: join early in a category-defining company shaping how enterprises tackle one of tech's biggest unsolved problems
Competitive pay and meaningful equity: a real stake in Harmonic's success, not a token gesture
A small, high-trust team: transparency, creativity, continuous learning, no politics, no bureaucracy
Thoughtful leadership that cares about your growth, not just your output
Annual global off-sites: past trips include Lisbon and Nashville
Real ownership: you'll shape a new part of the company from day one
