The role sits at the center of how Buffer connects with new users: SEO infrastructure, referral programs, conversion flows, backend experiments. Full-stack, high ownership, small trusted team.

We're hiring a Senior Growth Engineer at Buffer. This role caught my attention — growth engineering has one of the tightest feedback loops in tech. You build a referral flow, run an A/B test, ship something — and know quickly if it worked. That's rare.

That's not something you find everywhere. And after 10+ years in this industry, I don't take it for granted. Happy 15, Buffer. Here's to many more. 🎂

Carlos M. @cmunozgar.bsky.social · 01/12/2025

Some of the biggest moments of my life happened while working at Buffer. Not because of Buffer exactly, but Buffer was there, in the background, giving me the flexibility and stability to actually live my life while building my career.

Buffer turned 15 yesterday 🥳 I've been here for almost 5 years now — nearly a third of the company's entire existence. It's also the longest I've ever been at any company. That's wild to think about. In that time:

💡 Keeping the Lights On I was able to spend some time to fix three bugs and work on removing the unused queues for the legacy web workers recently removed. Keeping things clean while saving some money 🫰🏼

Some weeks are about flashy new features. This one was about making Buffer more reliable and removing tech debt that's been hanging around. The kind of work that users don't see directly, but definitely feel when things just work.

Buffer's Community feature launched last week and it's been a game-changer for managing comments across all my platforms in one calm, distraction-free space. Worth checking out if you're serious about turning engagement into growth. buffer.com/community

Buffer Community allows you to filter, sort, and reply to comments across multiple social media accounts to increase engagement and grow your audience.

If you're posting content but ghosting your comments, you're missing out on real growth opportunities. Every reply is a chance to build relationships, not just rack up vanity metrics.

Staying consistent with replies is actually making a difference! 📈 Got my first "Community Champion" badge with an 85/100 comment score in Buffer's new Community feature. Turns out responding to comments isn't just good etiquette—it's measurably boosting my engagement.

🔥 Caused a major incident: My SQS queue refactor took down password reset emails. One revert later, we're stable. Lesson learned: canary releases > big bang changes. The team's quick response was incredible. The incident was actually resolved by one of our Advocates @afarmer@bsky.social 💪🏼
