This team is on the front lines of making sure our platform is reliable, developer-friendly, and ready for the next stage of growth.

What We Value

Ownership

You follow through on commitments and create clarity when things are murky. You’re motivated by impact—not just intention—and you hold yourself and others accountable for outcomes.

Leaders who drive impact

You empower your team to deliver meaningful value to customers. You balance high standards with empathy, creating an environment where growth and results thrive.

A healthy skepticism for “the way things are done”

You bring curiosity and rigor. Best practices matter—but never more than progress and continuous improvement.

Brings 3+ years of hands-on SRE experience, designing and operating reliable, scalable infrastructure
Understands SaaS architecture, languages, technologies, and cloud infrastructure deeply enough to represent and advocate for their squad’s technical choices across the company
