• Design, launch and measure rapid experiments across channels such as partnerships, organic/content marketing, community building, referral programmes and paid media.

• Collaborate with the CEO, senior leadership, product, operations and engagement teams to align growth strategy with business objectives and ensure seamless user experience.

Required profile

• 3–6 years of experience in growth, performance or user‑acquisition marketing in a fast‑paced, data‑driven environment.

• Excellent English communication skills and ability to present strategies and results to C‑level leadership.
• Self‑starter who thrives with autonomy, moves quickly and is comfortable with ambiguity.

• Experience working across paid and organic acquisition channels with a systematic test‑and‑learn approach.
• Familiarity with SQL or data‑visualisation tools for deeper analysis.
