Job description

Join Infiterra and help power the future of subscription e-commerce.

Infiterra’s B2B SaaS e-commerce platform helps IT Distributors and Managed Service Providers (MSPs) automate and grow their subscription business. With 100+ customers in 75 countries, we're recognized for innovation and global impact—and we’re just getting started. We foster a collaborative and growth-oriented culture, allowing you to be part of a dynamic, forward-thinking team.

To support our global growth, we're hiring a Senior Integrated Marketing Manager (B2B SaaS) in London—our newest hub. We’ve just opened a WeWork office in the city, 2 steps away from Chancery Lane stop, and are building out a team to drive our UK expansion. It’s a great time to join: you’ll be part of shaping not just the role, but also our strategy,

The role in a nutshell:

We’re looking for a senior B2B marketer to own integrated campaigns and ABM programs across our priority segments in EMEA and North America.

You will work side-by-side with our Performance Marketing Manager:

• They focus on hands-on execution in platforms (LinkedIn, Google Ads, etc.)
• You focus on strategy, orchestration, and optimisation across channels and stakeholders

Your mission?

Design and run programs that move target accounts from awareness → pipeline → revenue, making sure every touchpoint (content, events, email, paid, web, sales plays) works together.

This year, the focus is clear: 1. Integrated, multi-channel campaigns (webinars, events, content, digital, email). 2. Launching and scaling ABM (1:many and 1:few) together with sales.

Our Ideal Candidate

You’re a senior B2B marketer who thinks in integrated programs, not isolated tactics. You know how to turn business goals and target accounts into clear campaigns that connect content, paid, events, email, and sales plays into one cohesive journey from awareness to pipeline. You’re comfortable partnering closely with Sales, BDRs, Performance Marketing, and Content — aligning on target account lists, follow-up plays, and what success looks like for each program.

You’re data-driven and outcome-focused: you care about qualified pipeline, SQLs, and revenue impact more than vanity metrics, and you use dashboards to decide what to stop, scale, or adjust. You enjoy the ABM mindset, working with Sales on account-based plays and reviewing engagement together. You bring structure, clear communication, and a calm, organized approach to managing multiple campaigns at once, and you’re excited to help build and scale an integrated, ABM-led demand engine.

What success looks like in your first 6–12 months:

You’ve put in place clear, integrated campaign plans for our top segments and regions, launched ABM programs with agreed-upon target account lists and playbooks, and established a predictable rhythm of reporting and iteration with Sales and Marketing. Campaigns are driving visible impact on MQLs, SQLs, and qualified pipeline. There is a shared view of the funnel across Sales, BDRs, and Marketing, and everyone knows which levers are working best and where to focus next.

What you will own:

1. Integrated Campaign & Demand Generation Strategy

• Build campaign plans by segment (targets, value propositions, offers, channels, KPIs).
• Turn company priorities into clear GTM programs with timelines, assets, and owners.
• Work with the Performance Marketing Manager to decide channels, budgets, and targeting, and to brief them and/or agencies for execution.
• Coordinate an integrated campaign calendar (webinars, events, content launches, email nurtures) to avoid conflicts and maximize impact.

2. ABM Programs (Launch & Scale)

• Design and run ABM programs (starting with 1:many and 1:few) across EMEA and NAM.
• Align with Sales on target account lists, personas, and plays per segment.
• Define and refine journeys and assets for priority accounts (webinars, events, nurtures, sales touchpoints).
• Partner with Sales, BDRs, and RevOps to:
  • Agree on entry/exit criteria (e.g. MQL, engaged account, opportunity, expansion).
  • Ensure clear, consistent follow-up (talk tracks, cadences, SLAs).
• Use ABM and analytics tools to monitor account engagement and pipeline influence and recommend what to scale, pause, or change.

3. Content, Offers & Sales Enablement

• Translate campaign and ABM strategy into clear briefs for content, creative, and web (landing pages, reports, webinar topics, email flows, in-event materials).
• Ensure each campaign has a coherent asset stack across the funnel (top, mid, bottom).
• Collaborate with Sales and SDRs on practical enablement: one-pagers, sequences, follow-up templates, talk tracks.
• Drive content repurposing (e.g. turning a hero report or flagship webinar into multiple formats across channels).

4. Events, Webinars & Partner Activities

• Plan and coordinate webinars, virtual events, and sponsored events as part of integrated campaigns in collaboration with the Senior Events & Comms Manager.
• Align pre-, during-, and post-event activities: invitations, reminders, in-event experience, sales follow-up, and content reuse.
• Ensure consistent messaging and positioning across event, digital, and sales touchpoints.

5. Measurement & Optimisation

• Define KPIs per program (MQLs, SQLs, pipeline created, influenced revenue, and key engagement metrics like CTR, CPL, and conversion rates by stage).
• Review performance regularly with Performance Marketing and agencies to make call-level decisions:
  • Pause/scale campaigns
  • Reallocate budget between channels, segments, or offers
  • Adjust messaging, creative, or audiences
• Use dashboards and reports to clearly communicate what’s working, what’s not, and next steps to Sales and Leadership.

Qualifications

• 6–10 years in B2B marketing, ideally in SaaS, with strong demand generation and ABM experience across EMEA and North America.
• Proven track record running multi-channel campaigns that generate pipeline and revenue (not just leads).
• Hands‑on collaboration experience with:
  • Sales and BDR teams
  • Performance/paid media specialists or agencies
  • Events and content functions
• Strong campaign and ABM planning: you can turn business goals into concrete programs, plays, and calendars.
• Confident in analyzing reports and dashboards, using data to make decisions (what to stop, scale, or adjust).
• Excellent stakeholder management and communication; comfortable working with C‑level and senior sales leaders on funnel definitions and program updates.
• Solid project management: able to run multiple campaigns in parallel without losing detail.

Bonus Points 🌟

• Familiarity with commercial metrics such as CAC, LTV:CAC, pipeline velocity, and payback.
• Comfort using AI tools to speed up research, copy creation, and analysis.

Sounds like you?

It is a Win-Win🌟

We offer a tech‑passionate team with a friendly culture and an international breed.

• Hybrid work.
• Flexible working hours.
• Work‑from‑anywhere scheme.
