Job description

You get to build Sentinel from the ground up, with real ownership, inside one of the more complex and interesting security environments around.

This is an investment firm that serves as the technology investment and operations arm of a family office. That means you are not just working internally for one business. You are operating across a portfolio of companies, each with their own environments and their own challenges. It keeps things varied and genuinely interesting.

On the security side, the function is scaling and this role sits right at the centre of that growth. You are coming in to design, build out, and own the Microsoft Sentinel SIEM. Not inherit something fully formed and manage it day to day. That distinction is key, because you'll need to have done this before.

This is a niche role: you'll need hands-on experience implementing or building out a Sentinel SIEM environment from the ground up, not solely managing, administering, or operating one that was already in place.

This role is based in Dallas, 3 days on-site and paying up to $200k base plus bonus.
