[Hiring] Senior Design Engineer @Buffer

Role Description

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. That means pushing our attention to design detail and craft further, improving site performance and accessibility, and creating the kind of consumer-grade web experiences that make people stop and notice. Our marketing site is the window into everything we're building, and as Buffer grows, we want the site to reflect that energy and ambition.

You'll work closely with marketing leadership, our UX designer, and customer advocates to understand what our 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 joining us means you'll work together as a team to test and confirm our ideas.

What you'll do

• Improve accessibility and performance across buffer.com through ongoing iteration.

Qualifications

• Strong front-end engineer with solid experience in React and TypeScript.
• Hands-on experience with front-end animation - whether through Motion, CSS animations, or creative approaches.

• Strong sense of visual hierarchy, spacing, typography, and user navigation.
