Head of Growth

Building a New Foundation for Cloud Security

The best security control doesn't detect a bad action. It removes the ability to perform it in the first place.

That's what Act does. We're an action-centric cloud security company focused on reducing cloud risk by removing excessive and unintended access across cloud environments. As AI is making attacks faster and less predictable, patching and detection can only go so far. So we make sure every identity in the cloud, human or machine, has only the access it actually needs, without turning security into an operational burden.

We're early-stage, well-funded, and built by repeat security operators who previously created Medigate (acquired by Claroty). We're building a team of exceptional people who take ownership from idea to outcome, with the autonomy to make decisions and drive their work forward. We care deeply about the customer, move fast, and enjoy building together.

If you want to build something that matters from the ground up and see your work go live within days, this is the place.

The Role

We're hiring a Growth Marketing Manager to build our growth function from scratch. You'll own pipeline, from first touch to qualified opportunity. You'll design the programs, run them, measure them, and cut whatever doesn't work. You'll report to the CMO and work closely with sales, product marketing and our agency partners.

What You'll Do

• Own growth campaigns end to end: Define audiences, offers, and channels; launch campaigns, test conversion journeys, and scale what works.

• Manage the BDR team: Set priorities, coach execution, and track performance. Align outreach with campaigns and target account plans to generate qualified meetings.

• Build account-based programs: Partner with Sales to prioritize accounts, map buying committees, and create tailored plays that open doors and accelerate deals.

• Run paid acquisition: Manage and optimize campaigns across LinkedIn and other relevant channels, including sponsored founder thought leadership.

• Turn engagement into pipeline: Build nurture and follow-up journeys around website visits, content, webinars, and events, with clear handoffs to Sales.

• Own marketing operations: Manage HubSpot as the system of record for campaigns, lead flow, scoring, and routing, and connect enrichment, intent, and automation tools.

• Own measurement: Track attribution, account engagement, and pipeline contribution, and use the results to guide priorities and investment.

• Drive SEO and GEO: Improve Act’s visibility in search engines and AI-generated answers through technical optimization and content strategy, in partnership with Product Marketing.

What You’ll Bring

• 4+ years of experience in B2B growth or demand generation, ideally in enterprise SaaS, cybersecurity, or cloud infrastructure, with a track record of generating qualified pipeline.

• Experience managing and coaching BDRs and building account-based programs in close partnership with Sales.

• Hands-on experience with LinkedIn Ads and HubSpot, including workflows, lead scoring, routing, and reporting.

• Strong analytical skills across attribution, funnel performance, and conversion optimization.

• Solid SEO knowledge and curiosity about GEO and AI-driven discovery.

• Strong English writing skills and a hands-on approach: you can turn technical ideas into clear campaigns, build a plan, and execute it.

Our culture

We live by three values: Win, Learn, Have Fun. We play to win - we set ambitious goals and hold ourselves to high standards. We learn constantly - from customers, from each other, and from our mistakes. And we have fun doing it: we believe great work happens when people enjoy working together.
