Senior Growth Intelligence Manager

Role Overview

At Attest, we're revolutionising how global brands like Unilever, Netflix, and Bloomberg turn consumer insights into competitive advantage. Positioned at the intersection of evolving technology and rapidly changing consumer behaviour, we're building the next generation of consumer intelligence that helps brands understand their customers better than ever before.

We're looking for a Senior Growth Intelligence Manager to help us better understand our growth channels and how to optimise and scale them to create growth for Attest. This is a hands-on builder role: you'll take ownership of how we measure, understand, and act on our marketing performance across both new customer acquisition and existing customer growth. You'll work closely with our Head of Growth Marketing and Revenue Operations, bringing dedicated analytical thinking and ownership to an area that is critical to our next stage of scale.

The Logistics

The base salary range for this role is £70,000 to £85,000 plus bonus.

We embrace a flexible hybrid work model. While we don't mandate specific office days, we ask full-time Attesters to work on-site 2 or 3 days per week. This allows us to collaborate in person, while ensuring enough time remotely for deep, focused work.

Key Responsibilities

Channel Intelligence & Attribution

• Own how Attest understands its growth channels by assessing what we currently measure, identifying the gaps, and helping define the right attribution approach for our business

• Work with the Head of Growth Marketing and Revenue Operations to develop a shared, trusted view of what is driving pipeline and revenue, and what is not

• Build reporting and insight frameworks that give the team and commercial leadership genuine confidence in budget and channel decisions, moving us away from incomplete or misleading proxies

• Bring your own point of view on the right model for a business like ours. We don't have all the answers, and this person is a key part of figuring that out

Experimentation & Optimisation

• Own the growth experimentation cadence from hypothesis to test to insight to action, and build it into a repeatable, rigorous system

• Drive continuous optimisation across channels, conversion points, and audience segments, with the statistical discipline to know what is actually signal versus noise

• Challenge existing channel assumptions and bring a point of view on where we should double down, pull back, or test something new

• Partner with the Head of Growth Marketing on paid strategy, SEO, ABM, and lifecycle, ensuring every channel is measured consistently and optimised intelligently

Scalable Personalisation

• Build the infrastructure for personalisation at scale: dynamic content, behavioural segmentation, and signal-based triggers, not just personalised one-off campaigns

• Ensure prospect and customer journeys feel joined-up and relevant across every touchpoint, from first click to closed deal

• Work with the broader marketing team to activate personalisation across email, web, and outbound in a way that compounds over time

Customer Acquisition & Expansion

• Develop a deep understanding of our inbound channel mix and the levers that drive efficient new pipeline growth

• Bring intent data and ICP signal work into our GTM motion, helping the sales team prioritise in-market accounts

• Own the growth intelligence layer for existing customers by identifying behavioural signals that indicate expansion readiness, churn risk, or upsell opportunity

• Build and optimise lifecycle marketing programmes that drive engagement, product adoption, and revenue expansion across the customer base

• Develop segmentation and personalisation strategies that make customer communications feel timely and relevant based on usage patterns and journey stage, not calendar cadence

Key Requirements

• A proven track record of B2B SaaS growth or performance marketing experience, ideally at a growth-stage company where you have had to create clarity from complexity

• Strong analytical foundation: comfortable in Salesforce, marketing automation platforms, and attribution tooling, able to build your own views rather than waiting for reports to be pulled for you

• Proven experience building something from scratch: an attribution model, an experimentation framework, a personalisation system, not just working within one someone else built

• Challenger mindset with the track record to back it up. You question assumptions, but you bring data and conviction, not just opinions

• Experience with multi-touch attribution tooling

• Familiarity with intent data platforms such as 6sense or Bombora and how to activate them in a marketing-led GTM

• Hands-on experience with AI tools in a marketing context, not as a talking point but as a genuine part of how you work

• Proven ability to work cross-functionally with Sales and Revenue Operations and earn trust with both

• The ability to communicate complex performance insight in a way that influences decisions at senior level

What Makes This Role Unique

• Own something real : this is not a support function, it is a core strategic capability that directly influences how Attest grows

• Genuine autonomy : to build the right models, challenge the existing ones, and shape how the team thinks about growth intelligence

• Early mover on AI in marketing : our horizon plan gives you a clear path to build increasingly sophisticated, AI-native growth systems

• Full-funnel visibility : you will sit at the centre of the commercial team, working with Marketing, Sales, and RevOps across both acquisition and customer growth

• Define and build : we don't have all the answers yet, and this person helps us find them

Our benefits

• Equity, everyone at Attest owns a piece of what we build together

• Work from anywhere up to 20 days a year

• 25 days holiday per year plus additional festive days

• Private Medical Insurance

• 1 day per quarter to do charity or community work

• Family friendly benefits, including enhanced parental leave (18 weeks paid leave for Primary carer), up to 12 weeks paid leave for premature births and neonatal care and paid leave for IVF and fertility treatment and pregnancy loss

We want to give everyone the opportunity to showcase their best selves during the interview process and beyond. Do let us know if there are any adjustments you’d like to make to ensure it’s more inclusive – we’re learning too, so we’re more than happy to adapt and accommodate where possible.
