About the Role You'll join the Infra Platform team, the backbone of everything engineering at Vibe. We own hosting, provisioning, observability, CI/CD, internal tooling, security, and compliance. Every product and platform team runs on what we build. You’ll report to our Lead Platform Engineer, and together with the team, you’ll help shape the technical direction and uphold the infrastructure standards the whole company relies on.

You’ll work on infrastructure handling more than 600k QPS, latency targets under 10ms, and over 5 PB of storage. Just as importantly, you’ll be someone other engineers turn to when the hard problems show up, which gives this role real influence across the company.

Nice to Haves Built internal developer tooling, service scaffolding, unified observability portals, self-serve provisioning Hands-on experience with SOC2 compliance, you've helped a team get there, not just read about it Our Values At Vibe, we run on three values: Impact , Ambition , and Urgency . We tie every goal to a real business outcome, think 10x rather than settling for good enough, and move daily rather than waiting for perfect conditions. You'll thrive here if you own outcomes without needing direction, default to action, and hold yourself to results, not effort. This is a high-performance environment with high-performance rewards: you'll work alongside people who push you, with real ownership over hard problems in a market that's moving fast.
