Senior DevOps / SRE Engineer

Location: Based in US to GMT timezones

Remote | Full-time

Compensation: $120K - $150K

A confidential client operating at the intersection of decentralized finance and artificial intelligence is seeking a Senior DevOps / SRE Engineer. Our client develops sophisticated infrastructure for autonomous AI trading agents on the Hyperliquid network. This role is critical to the organization’s mission: managing high-stakes environments where infrastructure reliability directly impacts capital protection.

The successful candidate will own the architecture that keeps dozens of concurrent AI agents alive, fast, and secure. Unlike traditional web applications where downtime results in a 404 error, downtime in this environment means open financial positions are left unprotected. This is a high-impact position designed for an engineer who thrives on building resilient, zero-downtime systems for autonomous agents managing real-time financial workloads.
