<p class="artifact-docx-preview_heading2">Are you a detection engineer who wants to bring real depth of expertise into a new and growing function and use it to deliver security excellence to customers? Expel's professional services practice is just getting started, and we're looking for the technical expert who'll deliver the work that gets customers ready to thrive under our co-managed SIEM model. You'll bring hands-on skill to a team that's finding its stride, help it grow, and have a real runway to grow into a lead yourself.</p> <p class="artifact-docx-preview_heading2"><span id="_9o5evrx3ei92"></span>Here's the work. Customers come to us with SIEMs that should be surfacing threats but are instead consuming their teams: ingestion costs climbing year over year, engineers buried in alert noise and broken pipelines, and detection blind spots leaving real gaps. You're the engineer who turns that around: authoring and tuning detection content that satisfies real security use cases, closing coverage gaps, migrating detection logic off legacy platforms, and helping optimize what customers ingest and pay for, so their SIEM becomes a force multiplier again, not a management burden.</p> <p class="artifact-docx-preview_heading2"><span id="_9o5evrx3ei92"></span>And because this function evolves right alongside our customers and the market, the work won't stand still. Expect it to grow into deeper integrations, automated and AI-assisted tooling, and security strategies our customers need next.</p> <h2>What Expel can do for you</h2> <ul> <li
