About the company

K2 Space is a manufacturer of large, high-power satellites.

About this role

<div class="content-intro">K2 is building the largest and highest-power satellites ever flown, unlocking performance levels previously out of reach across every orbit. Backed by <a href="https://www.forbes.com/sites/aliciapark/2025/12/11/this-startup-is-building-huge-satellites-for-an-underused-interstellar-sweet-spot/?ctpv=searchpage">$450M</a> from leading investors including Altimeter Capital, Redpoint Ventures, T. Rowe Price, Lightspeed Venture Partners, Alpine Space Ventures, and others – with an additional $500M in signed contracts across commercial and US government customers – we’re mass-producing the highest-power satellite platforms ever built for missions from LEO to deep space.  The rise of heavy-lift launch vehicles is shifting the industry from an era of mass constraint to one of mass abundance, and we believe this new era demands a fundamentally different class of spacecraft. Engineered to survive the harshest radiation environments and to fully capitalize on today’s and tomorrow’s massive rockets, K2 satellites deliver unmatched capability at constellation scale and across multiple orbits.  With multiple launches planned through 2026 and 2027, we're Building Bigger to develop the solar system and become a Kardashev Type II (K2) civilization. If you are a motivated individual who thrives in a fast-paced environment and you're excited about contributing to the success of a groundbreaking Series C space startup, we’d love for you to apply. </div>The Role  K2 is a target for sophisticated adversaries, from nation-state actors to criminal groups, all intent on stealing or disrupting the technology behind a new class of high-powered satellites. This role owns detection and response for our corporate environment: you’ll run and mature our SIEM, build detections against real adversary tradecraft, triage what fires, and drive incidents from first signal through containment, eradication, and lessons learned. You’llbe deeply hands-on across identity, endpoints, SaaS, network, and cloud telemetry, closing the visibility gaps you find rather than simply documenting them. This is a role for someone who thrives on real-world impact and operates with urgency when it counts. Every detection you write and every incident you shut down directly supports our ability to move fast, operate confidently, and deliver breakthrough satellite capabilities.  Responsibilities  <ul> <li>Own day-to-day detection and response across the corporate environment, from alert triage and investigation through containment and remediation </li> <li>Administer and mature the SIEM, including log source onboarding, parsing and normalization, telemetry enrichment, rule tuning, and platform health, retention, and cost </li> <li>Write, test, and maintain detection content mapped to MITRE ATT&CK using detection-as-code practices, including version control, peer review, and automated testing </li> <li>Act as incident commander for corporate security incidents, coordinating stakeholders and delivering timelines, root cause analysis, and post-incident follow-through </li> <li>Build response playbooks and automation across SOAR, scripting, and vendor APIs to reduce time to detect, triage, and contain </li> <li>Threat hunt proactively across endpoint, identity, SaaS, and cloud telemetry using threat intelligence and hypotheses about adversary behavior </li> <li>Run adversary emulation
