Systems Administrator

Senior IT Infrastructure & Cloud Administrator

Infrastructure, Cloud Operations, Security & Automation

 Position Overview

We are looking for a Senior IT Infrastructure & Cloud Administrator to take ownership of the company's internal IT infrastructure, cloud environments, systems administration, security, and operational efficiency.

This is a hands-on senior-level role that combines infrastructure administration, cloud operations, IT security, compliance, and automation. The ideal candidate will be responsible for maintaining and improving the company's IT ecosystem, ensuring system reliability, optimizing cloud costs, strengthening security, and automating routine IT processes using modern tools, including LLM-based solutions.

This is not a traditional ticket-execution role. We expect someone who can independently assess the infrastructure, identify potential issues and improvement opportunities, prioritize tasks, and drive initiatives from identification to completion with minimal supervision.

The position involves direct visibility and collaboration with the CTO, CEO, and CSO. The successful candidate must demonstrate strong technical judgment, ownership, reliability, and the ability to manage systems that involve production access, financial information, and compliance requirements.
