The Role

You will be a key social and influencer strategist.

A strategist who lives inside platforms, reads culture in real time, and translates signals into ideas that move both the brand and the business.

You will shape social and influencer strategies for always-on programs and integrated campaigns across Instagram, X, TikTok, LINE, YouTube and emerging platforms. You will connect organic, paid, owned and earned media into one cohesive ecosystem while ensuring strategies remain insight-led, platform-native and aligned with broader business and marketing objectives.

You will work closely with clients, creative, production, media, analytics and external partners to translate strategy into execution, ensuring every piece of work delivers measurable business impact.

You will use social tools, AI, and data to build smarter workflows, stronger insights and faster delivery.

This role suits someone who is strategic, hands-on, commercially minded and passionate about helping brands grow through social and influencer marketing. You will be expected to take ownership of strategic workstreams and lead projects from strategy through execution, while collaborating closely with cross-functional teams across the business. Someone who thrives in ambiguity, simplifies complexity and consistently raises the quality of work around them.

You think. You do. You deliver.
