What You’ll Be Doing

• Developing and executing multi‑channel acquisition strategies across paid social, search, display and programmatic channels.

• Designing and running A/B and multivariate experiments across landing pages, creatives and user funnels; owning test prioritisation and learnings.

• Managing lifecycle and retention activities including email, push and in‑app campaigns with segmentation and personalisation.

• Working with Creative to brief, iterate and optimise campaign creatives and messaging for performance and brand consistency.

• Partnering with Data and Product to define success metrics, build attribution models and ensure clean, actionable reporting.

• Monitoring and optimising channel performance to meet CPA, CAC and ROAS targets; managing budgets and bids effectively.

• Building dashboards and presenting insights and recommendations to stakeholders, translating data into clear action plans.

• Documenting processes, playbooks and learnings to scale repeatable growth approaches across the business.

What We’re Looking For

• Proven experience in growth, performance or digital marketing roles within an agency, start‑up or in‑house team.

• Practical experience designing and analysing experiments (A/B testing) and translating results into decisions.

• Comfortable with analytics tools (e.g. Google Analytics, GA4, Looker/Looker Studio, Mixpanel) and spreadsheet analysis.
