We are hiring on behalf of our client who is a high-growth development firm behind a market-leading digital asset launchpad. Operating at a massive scale with over
$750M in daily trading volume and nearly
$1B in revenue generated over the last two years, the organization maintains a lean, high-impact team of fewer than 100 people.

This individual will be responsible for ensuring that cloud infrastructure remains reliable, scalable, and compliant under real-world financial constraints and rigorous regulatory expectations.
