About the Role:

We are building systems that operate at scale - high write volumes, real-time state sync, and burst traffic that doesn’t politely warn before it arrives. We are looking for engineers who love owning systems end-to-end, care deeply about performance and reliability, and want to build things that don’t just work - but last. This is not a ticket-execution role, its a system ownership role.

• Improve Core Web Vitals and perceived performance

Observability & Production Ownership:

• Instrument logs, metrics, traces, and alerts
• Participate in on-call
• Debug real production issues
• Drive post-mortems to meaningful closure (not just documents)

Mentorship & Leverage:

• Review code thoughtfully
• Support junior engineers
• Raise engineering standards across the team

Requirements:

• 4+ years of professional engineering experience
• Strong backend-heavy fullstack background
• Deep comfort with Node.js + TypeScript
