We’re at a pivotal growth stage and are looking for a senior marketing leader who can help define and execute the next chapter of our go-to-market strategy.

The Role

This is a hands-on leadership role for an experienced B2B SaaS marketer who can operate at both strategic and executional levels.

As Head of Marketing, you will own Atominvest’s marketing strategy end to end — from positioning and messaging, through demand creation and capture, to revenue impact. You will work closely with the leadership and sales teams to build a scalable, measurable marketing engine that drives pipeline and revenue, not just leads.

This role retains meaningful individual contributor responsibility, especially in the near term, while also shaping the long-term marketing vision, systems, and priorities.

Demand Creation & Growth

Design, execute, and iterate multi-channel demand creation programs that increase both inbound volume and quality
Build and scale campaigns across LinkedIn, Google and other relevant channels
Own content-led demand initiatives including webinars, thought leadership, reports, and subject matter expert driven content
Build a repeatable “content engine” that compounds over time through repurposing and distribution

Revenue & Pipeline Accountability

Own marketing’s contribution to pipeline and revenue, not just MQLs
Partner closely with Sales to define targets, measure impact, and continuously improve conversion
Use data to prioritise initiatives that move real commercial outcomes

Demand Capture & Conversion

Build and optimise a high-performing demand capture engine across paid and organic channels
Improve website journeys, conversion rates, and on-site messaging through testing and iteration
Ensure marketing activity translates into meaningful sales conversations

Product Marketing & Positioning

Bring the voice of the customer into all messaging through call reviews, interviews, and feedback loops
Build and maintain strong competitive positioning and sales enablement materials
Work closely with Sales to refine narratives, talk tracks, and go-to-market assets

Account-Based Marketing (ABM)

Design and execute 1:1 and 1:many ABM programs for strategic target accounts
Partner with Sales to align messaging, timing, and outreach
Measure and communicate ABM impact on pipeline and revenue

Analytics, Insight & Optimisation

Analyse performance across all marketing activities and channels
Rapidly iterate based on data and insight
Clearly tie marketing performance back to business outcomes and revenue
Define and track the right KPIs for a scaling B2B SaaS company

Leadership & Collaboration

Work closely with the leadership team to shape go-to-market strategy
Act as the voice of the customer internally
Help define priorities, sequencing, and focus as the company scales
Over time, help shape and grow the marketing function

What We’re Looking For

Experience & Skills

Proven experience leading and executing growth initiatives in B2B SaaS
Strong track record of driving pipeline and revenue, not just awareness
Deep experience in demand generation, content-led growth, and ABM
Strong product marketing instincts — messaging, positioning, and competitive differentiation
Highly analytical, comfortable with data, experimentation, and optimisation (A/B testing, CRO, attribution)

Ways of Working

Strategic thinker who can also execute — comfortable being hands-on
Confident prioritising in a fast-paced, scaling environment
Creative and commercial — able to balance brand, demand, and revenue
Self-starter with strong ownership mentality
Comfortable running multiple initiatives in parallel, from concept to delivery

Mindset

Customer-first and outcomes-focused
Curious, experimental, and not afraid to challenge assumptions
Energised by building, iterating, and improving rather than maintaining the status quo

Why This Role Is Compelling

You’ll own marketing end to end at a critical growth stage
You’ll shape the narrative of a category-defining private markets platform
You’ll work directly with senior leadership and influence company strategy
You’ll have the opportunity to build a marketing engine that truly drives revenue
You’ll join a business that values outcomes over activity — in marketing as much as in product
