About The Position

Seasats is growing rapidly, and we’re looking for a Senior IT Systems Administrator to become the dedicated owner of our internal IT systems. You’ll support a team of approximately 100 people working across software, engineering, manufacturing, operations, and field testing. Your job will be to make sure employees have secure, reliable, and well-supported technology, and to build the systems and processes that will continue working as the company grows. You’ll handle day-to-day support, administer our core business systems, manage employee devices and accounts, improve our office networks, and strengthen our security practices. At the same time, you’ll have substantial freedom to evaluate our current environment and establish a thoughtful, scalable approach to IT. We’re looking for someone who enjoys taking ownership and fixing immediate problems, and is excited to mature our enterprise processes over time. As Seasats’ primary IT professional, you will own internal IT across the company. This role primarily supports Seasats’ internal business technology. It is distinct from the software and infrastructure used to operate our autonomous vehicles, although you’ll work closely with those technical teams and may occasionally help connect the two environments safely.
