Senior Backend Engineer

We’re looking for experienced backend engineers who care deeply about reliability, performance, and scalability. You’ll design, build, and evolve the systems that power communication at massive scale - while helping us push the boundaries of what great engineering can look like.

What We Value

Ownership
You own problems end to end. You move fast, act like an owner, and thrive in ambiguity. You've led complex projects before, whether officially or not, and you're ready to do it again.

Engineers with product taste

You think like a user, not just an engineer.  You care how your systems power real customer value - and how to make them better.

A healthy skepticism for “the way things are done.”

You bring rigor and creativity. Best practices matter - but never more than forward motion.

What You’ll Do

• Design and build distributed systems in Go that help customers send timely, relevant messages at scale
• Collaborate across teams to debug issues and deliver reliable solutions
• Own problems end to end - from architecture and schema design to testing, deployment, and monitoring
• Share knowledge and raise the bar through sharing your progress publicly with short videos, thoughtful writing, and mentorship
• Leverage AI tools to prototype, move faster, and make better decisions

What we're looking for

• 7+ years of experience building scalable, distributed systems in Go (or similar statically typed languages)
• Comfort working in cloud-native environments (AWS, GCP)
• Familiarity with relational databases (we use MySQL) and an understanding of performance tradeoffs
• Experience with observability tooling and operating production systems
• A bias for action over perfection, and pride in owning technical decisions
