About the Role

• We're looking for a Senior Design Engineer to join Buffer's Marketing team.
• You'll be the engineer closest to how Buffer looks and feels on the web — owning our front-end design system, building performant components, and crafting the interactions and animations that bring our pages to life.
• This is a small, agile team where members are trusted to manage their own time, and where you'll work across brand, product marketing, and growth projects.
• Buffer recently went through a significant brand redesign, and now we want to scale it by pushing attention to design detail and craft, improving site performance and accessibility, and creating consumer-grade web experiences.
• You'll work closely with marketing leadership, our UX designer, and customer advocates to understand what visitors need and figure out the best way to build it.
• You'll write and ship high-quality, tested code, and contribute to front-end engineering standards that raise the bar for consistency and quality across our marketing codebases.
• Working at Buffer is collaborative and positive thanks to our core values; we try to be "No Ego Doers" who are aware of our assumptions and work together as a team to test and confirm ideas.
• This role reports to Kateryna Porshnieva, Head of Engineering Operations, and sits on the Marketing team.
• You'll collaborate on a variety of Brand and Product Marketing projects with the full Marketing team, partnering closely with Simon Heaton, Director of Growth Marketing, and Hailley Griffis, Head of Communications and Content.
• You'll work day-to-day with most of the team, in particular Kate Baldrey, our Marketing UX Designer, to build web experiences that help people learn about and sign up for Buffer.

What You'll Be Doing

• Build polished, interactive web experiences for buffer.com — product launch pages, brand storytelling, landing pages, and marketing tools — in close collaboration with Kate (UX Design) and the wider marketing team.
• Bring pages to life with thoughtful animations and interactions using Motion, CSS animations, or whatever approach fits.
• Evolve and maintain Buffer's design system and component library — improving consistency, filling gaps, and refining patterns so the whole team can ship high-quality pages without starting from scratch each time.
• Improve accessibility and performance across buffer.com through ongoing iteration — auditing what's there, fixing what needs fixing, and raising the standards over time.
• Help shape how we work by pairing with engineers, reviewing code, and sharing what you know about front-end architecture, design systems, and accessibility patterns.
