Senior Performance Marketing Manager

This is a highly impactful role for an experienced performance marketer with a strong background in B2B SaaS, ideally working with mid-market to enterprise-level customers.

The successful candidate will be a highly analytical, data-driven marketer with a proven track record of driving growth through performance marketing. You will take ownership of paid media strategy and execution across the full funnel, using data, experimentation and customer insight to drive qualified leads, acquisition, engagement and revenue.

You will have experience across paid search, paid social, display and programmatic channels, combined with the ability to operate strategically while remaining hands-on with campaign optimisation and execution.

The Role

As the Senior B2B Performance Marketing Manager, you will work closely with the wider Marketing team and cross-functional stakeholders across Sales, Product, Data and Commercial teams to develop, test and iterate performance marketing campaigns that deliver measurable business results.

You will own, develop and scale paid media campaigns across the full customer journey, with a focus on driving acquisition, adoption, engagement and revenue growth.

The ideal candidate will be equally comfortable developing a long-term channel strategy and getting into the detail of campaign performance, making tactical optimisations and quickly responding to opportunities in a fast-growing and sometimes ambiguous environment.

You will also play an important role in fostering a creative and experimental culture, developing new approaches to ad creative and targeting, building robust testing frameworks and using performance data to identify and scale what works.
