Content Marketing Manager - 6 month ftc in Knutsford

Who are PortSwigger

PortSwigger exists to enable the world to secure the web. We build the tools practitioners trust, the knowledge that trains security professionals, and a community that makes anyone who cares about security better, so anyone can make the internet safer. Our products are crafted with care, backed by deep research, and we lead through generous innovation: winning by setting the bar higher and sharing what we create, turning commercial success into wider positive impact. Our culture didn't happen by accident; it was built deliberately, and it's something we protect with the same care we put into everything we make. We default to trust enabling brilliant people doing brilliant work, free from micromanagement. We aim for excellence, and we do it with care; performance and compassion go hand in hand. Joy, mastery and purpose belong together here and if the work stops feeling good, we take that seriously.

Growth is our commercial engine: bringing new customers on board, keeping them delighted, and telling our story to the market. Growth is split into Sales, Customer Experience (Relationship Management, Customer Success and Tech Support), Marketing and Special Ops. Collectively owning pipeline, retention, advocacy and the go-to-market playbooks that scale PortSwigger.

What you'll be doing

You'll join PortSwigger on a six-month fixed-term contract as a senior individual contributor, bringing cohesion to our content across enterprise and practitioner audiences. You'll be the point person for the consolidated content and communications plan, making sure launches, campaigns and research-led stories land clearly, credibly and at the right time. This is expertise we're bringing in to build the foundations: the story we tell the market, how consistently we tell it, and an AI-native way of producing content that lets us do more without the bar slipping. You'll be a strategist and editor, not a copywriter. AI, our content engine, our experts and our partners supply much of the production. You make sure it all adds up to one company with one clear story.

What you'll own

• One story, one plan. You'll make sure we're telling the market a coherent story across enterprise and practitioner audiences. You'll bring existing activity together into one content and communications plan and calendar that Marketing and the other teams who publish work from, so launches and campaigns land coherently and nobody collides.
• A consistent voice. You'll define and embed shared frameworks for tone of voice, style, how messaging is applied, content standards, and campaign planning and briefs. You'll build them so both people and our AI tools apply them by default. Teams use them because they make the work better, not because someone is chasing.
• Content each audience values and acts on. You'll shape the core launch, research-led, campaign and enterprise content with product marketing, researchers and other experts. For practitioners it needs to be technically right and credible. For security leaders and buyers it needs to be clear on value, risk and outcomes. In both cases it should give people a reason to act.
• AI-powered content at scale. You'll own how we use and orchestrate AI across research, drafting, adaptation, editing, quality control and measurement, and set the quality bar for our content engine, AI tools and partners. Human judgement stays central. You'll document the workflows so others can reuse what works.
• Evidence of what works. You'll agree baselines early, measure what content changes for each audience, and use that to change the plan, not just report on it.

What good looks like

• Month 1: you understand both audiences and what’s in flight, have brought existing plans into one, and have agreed baselines and targets.
• Month 3: one plan is running, the shared frameworks are in use across teams, and evidence shows what moves each audience.
• Month 6: there’s clear improvement against the baselines, we’re producing more, faster, at the same quality, and a reusable playbook is ready for whoever comes next.

How you'll work

You'll work closely with product marketing, demand generation, community marketing, social, sales, researchers and product teams, through influence rather than authority. Product positioning, lead targets, PR, analyst relations, events, and social and digital channels are owned elsewhere. This role applies messaging consistently and makes sure the content plan and content quality support the wider go-to-market motion.

Requirements

What you'll bring

• You've brought cohesion to content across more than one audience.
• You've led content for technical B2B audiences, across both expert users and enterprise buyers, and have a portfolio that shows it, with commercial or behavioural outcomes.
• You've brought scattered plans, publishing activity and teams together into one plan and calendar.
• You've created shared standards (tone of voice, style, messaging frameworks, briefs) that teams actually adopted.
• You have the editorial judgement our audiences demand.
• You can turn a technical product, launch or research story into content that changed what people did.
• You spot content that is technically wrong, not credible enough or wrong for its audience, and you know when to bring in an expert.
• You've used performance evidence to change a plan, not just report on activity.
• You work AI-native, with judgement.
• You use and orchestrate AI across content production and content marketing every day, and can show the workflows, beyond a mention on your CV.
• You can show where AI increased output or speed without lowering quality, and how you check what it produces.
• It's a big plus if you've built AI content workflows or agents that others use.
• You take people on the journey with you. You're personable, collaborative and low-ego, with clear communication and reliable follow-through.
• You're comfortable working with experts, sales, product marketing, demand generation and channel owners, and you respect role boundaries.

The practical bits.

You'll work from our Knutsford HQ on the agreed office pattern for the full six months. You're available to start within a few weeks and are looking for a six-month fixed-term engagement. You have the right to work in the UK. Security, developer-tools or infrastructure experience is a strong plus, not a requirement. We don't set a minimum number of years: show us the evidence.
