Account Supervisor

Collier.Simon is an independent, full-service creative agency in the Los Angeles/Hollywood area. We work with our client partners to develop creative solutions that truly move the needle. Clients range from Fortune 500-type household names to up-and-comers across a variety of industries / verticals. We’re in the midst of a tech-powered transformation, using AI to supercharge creativity, not replace it, and we’re looking for curious minds excited to explore AI as a tool to scale, spark, and speed up creativity.

We’re looking for an Account Supervisor — a client lead with 5–7 years of experience managing multi-channel campaigns who can balance sharp organizational skills with strategic thinking. This role is part account management, part creative, and part strategy, and is ideal for someone who thrives in fast-paced, collaborative environments.

You’ll need to be as comfortable building timelines as you are crafting deck narratives, pulling insights as you are pitching campaign ideas, and managing budgets as you are shaping go-to-market plans. While not required, we value curiosity about how AI tools can help work flow more efficiently, spark fresh ideas, and enhance creative and strategic output across account, creative, and strategy needs.
