Role overview

As Head of Marketing B2B (Onoff Business), you own the B2B marketing engine end-to-end: positioning, messaging, inbound/demand generation, sales alignment, CRM/lifecycle, and B2B brand credibility. Your mission is to build a repeatable, scalable GTM system that turns Onoff Business into a clear, compelling, and measurable growth driver.

This is not a “paid acquisition only” role. It is a GTM marketing leadership role with measurable impact on pipeline and revenue.

Core missions

1) Own B2B GTM: positioning, ICP, messaging

• Clarify ICPs, personas, use cases, and buying triggers (with Sales + Product).

• Build and continuously refine value propositions, proof points, and differentiation.

• Create sales-ready messaging frameworks and narrative consistency across touchpoints.

2) Build the inbound & demand generation engine

• Define the B2B channel strategy (inbound-first) and scalable conversion paths.

• Drive content strategy, SEO-led acquisition, webinars/partner programs where relevant, and conversion optimization.

• Create high-performing B2B landing pages and campaigns aligned with segments and use cases.

3) Sales alignment & pipeline discipline

• Establish a strong Marketing–Sales operating model: definitions (lead/MQL/SQL), SLA, handoff, feedback loops.

• Own pipeline reporting (marketing-sourced / marketing-influenced), lead quality, and funnel conversion improvements.

• Build sales enablement assets (pitch deck, battlecards, case studies, email sequences).

4) CRM & lifecycle for B2B growth

• Design and optimize lead nurturing, scoring, segmentation, and activation flows.

• Partner with RevOps/Sales Ops (or own the framework if needed) to improve conversion through CRM-driven journeys.

5) Data, operations & performance management

• Build dashboards and a clear measurement framework (CPL/SQL, pipeline €, conversion, velocity).

• Prioritize what to stop/start based on measurable outcomes.

6) Team & partners

• Lead and coach a B2B marketing squad (internal and/or agencies).

• Manage external partners (content/SEO, creative, PR if relevant, tooling) with clear deliverables and KPIs.

First 6–12 months priorities

• Produce a crisp B2B positioning + messaging system usable by Sales and visible on the website.

• Attend Business events.

• Launch a structured inbound plan by segment/use case (content + SEO + conversion).

• Implement a predictable lead-to-SQL process (SLA + reporting + quality loop).

• Deploy activable CRM/lifecycle flows that lift conversion and pipeline velocity.

• Build a B2B proof system: case studies, testimonials, reference architecture, security/IT reassurance (as applicable).

Ideal profile

• 8+ years in B2B marketing roles (SaaS/tech strongly preferred).

• Proven experience owning positioning & messaging and building inbound/demand gen systems.

• Strong Marketing–Sales alignment track record (SLA, enablement, reporting, pipeline accountability).

• Comfortable with CRM/lifecycle (segmentation, scoring, nurturing, automation logic).

• Strategic and hands-on; able to produce outputs and run the operating rhythm.

• Fluent in English and French.
