System Engineer

As we continue to grow, we’re looking for an Ops Engineer who enjoys digging into complex problems, improving reliability and security and turning recurring issues into structural solutions.

As a System Engineer, you’ll sit at the intersection of engineering, operations and product. You’ll be part of our DevOps team, but your impact will reach across our platform and engineering squads.

You’ll investigate recurring incidents, alerts and vulnerabilities, make problems visible through strong observability and turn reactive firefighting into proactive prevention.

You’ll also develop a strong understanding of our product and use that knowledge to build tools that help our Support and Engineering teams diagnose and resolve issues faster. What you’ll do

• Build internal tools, scripts and diagnostics that help Support resolve common issues independently.
• Identify patterns in support requests that point to underlying product or infrastructure issues.
• Work closely with engineering squads and DevOps on infrastructure, security and reliability improvements.
• Turn incidents and learnings into structural improvements that make our platform more resilient.
