Job description

You're not here to maintain someone else's platform. You're here to define how reliability works across an entire engineering organization.

This is a SRE role at one of the world's largest hedge funds, with a genuine engineering-first culture. Technology isn't treated as a support function here-it's a core part of the business, backed by significant investment and a track record that speaks for itself.

You'll be building the tooling that hundreds of engineers rely on every day. That means getting deep into observability, automation, and infrastructure, and doing it at a scale where the decisions you make actually matter.

You'll partner closely with engineering teams across the organization, driving automation and shaping reliability practices from the ground up. You'll have real ownership and the autonomy to move fast and do things properly.

You'll be working across GCP, Terraform, Ansible, and CI/CD pipelines, with strong observability tooling like Datadog at the center of how you understand system health. You'll bring solid Python skills and a deep understanding of distributed systems and what it actually takes to keep them reliable at scale.

Ideally you've already built or operated scalable, reliable systems in complex environments. You know how to work with engineering teams, not just support them, and you understand that the best reliability work happens when you're embedded in the product, not watching from the outside.

The compensation reflects the seriousness of the role, starting at $175,000 - $300,000 base plus a highly competitive performance bonus, with the kind of exposure to best-in-class engineers and modern tooling that genuinely accelerates a career.
