Senior Brand Designer - Growth

Mercury Mercury · Fintech · Remote · Brand Design

Mercury is seeking a Senior Brand Designer with a focus on growth and performance creative. This role will own the creative vision for Mercury's growth channels, design paid ad creative, and use creative testing as a strategic tool. The designer will also partner with growth marketing, translate product UI into visual moments, design for lifecycle marketing, art-direct video, build scalable creative systems, and contribute to the brand system. A key aspect of the role is the genuine fluency with AI as part of the creative practice, using AI design tooling to scale and iterate on creative faster and produce bespoke assets.

What you'd actually do

  1. Contribute across the full range of Brand Studio work — campaigns, web, social, and brand initiatives — alongside a team that holds craft and intention to a high standard.
  2. Own the creative vision for Mercury's growth channels — establishing what brand excellence looks like at the performance layer and building the standards that sustain it.
  3. Design paid ad creative across static, motion, and social formats, with a point of view on how each placement can reinforce Mercury's brand while driving results.
  4. Use creative testing as a strategic tool by developing hypotheses, taking creative risks, and translating what you learn, both quantitative results and qualitative signal, back into stronger creative direction and into the brand itself.
  5. Partner closely with growth marketing on campaign briefs, iteration cycles, and channel strategy.
