Cyber Defense Analyst II

About the role

At Blue Origin, we envision millions of people living and working in space for the benefit of Earth. We’re working to develop reusable, safe, and low-cost space vehicles and systems within a culture of safety, collaboration, and inclusion. Join our team of problem solvers as we add new chapters to the history of spaceflight! The role is part of the In-Space Systems business unit, which is focused on addressing two of the most compelling challenges in spaceflight today: space infrastructure and increasing mobility on-orbit. Blue National Security (BNS) builds and operates space systems for the Intelligence Community and Department of Defense. Someone has to be watching those systems continuously — and that's this role. We're looking for a Cyber Defense Analyst to monitor, investigate, and respond across BNS classified enclaves, mission ground systems, and labs. You'll work real events on real national security systems, and you'll do it alongside senior engineers who will teach you the environment rather than hand you a queue and walk away. This is a hands-on-keyboard role. You'll spend your days in consoles, terminals, and logging data. You'll also get your hands on the tooling itself, helping deploy sensors, onboard log sources, and tune detections under the direction of our senior engineers. That's how you'll learn this environment, and it's the fastest path to becoming the engineer who designs the next one. If you're coming off a military cyber protection team, a government SOC, or a service watch floor and you want to keep growing technically rather than get slotted into a ticket queue, this is a strong landing spot.

Responsibilities

• Monitor and triage: Work security events and alerts across SIEM, EDR, network sensors, and audit logs. Determine what's noise, what's misconfiguration, and what warrants escalation.
• Investigate: Pull the threads — pivot across host, network, and identity data to build a picture of what actually happened, and document it clearly.
• Respond: Serve as first responder during incidents. Execute containment steps per playbook, preserve evidence, build timelines, and support senior engineers leading the response.
• Hunt: Participate in structured hunts, initially alongside senior team members and increasingly on your own hypotheses as you learn what "normal" looks like here.
• Support audit and insider threat review: Perform privileged user activity monitoring and audit log review in partnership with Security and Counterintelligence.
• Stand watch during mission events: Provide heightened monitoring coverage during launches, mission operations, and other critical windows.
• Get hands on the tooling: Assist with sensor deployment, log source onboarding, and agent rollout across enclaves under engineering direction.
• Tune and improve detections: Reduce false positives, validate rule coverage, and propose new detections based on what you find in the data.
• Improve the playbooks: Execute response procedures and flag every gap you hit — you'll be the first to find them, and your input drives the rewrites.
• Automate what you repeat: Script recurring triage, enrichment, and reporting tasks. We'll help you build this skill if you don't have it yet.

Required Qualifications

• 2+ years of hands-on experience in security operations, incident response, IT operations, or system
