Application close date:
Applications will be accepted on an ongoing basis until the requisition is closed.

As part of a small, accomplished team of experts, you will protect and secure the endpoints that Blue Origin's engineers, technicians, and business teams depend on every day. You will share in the team's impact on all aspects of endpoint security, and you will lead and assist with many aspects of operations and engineering on the Endpoint Experience team.

Security engineers evaluate, select, procure, implement, and operate security technology supporting enterprise and space systems. This role is the technical lead for our AV and EDR stack - Microsoft Defender for Endpoint and Tanium - and it is deliberately operating-system agnostic. You will be expected to reason about detection coverage, agent health, and security posture with equal fluency across all systems.

We are looking for someone to apply their technical expertise, leadership skills, and commitment to quality to positively impact safe human spaceflight. Passion for our mission and vision is required.

Responsibilities

Microsoft Defender for Endpoint
- Own endpoint detection and response coverage across the fleet: onboarding and offboarding, agent lifecycle, platform build currency, and tamper protection, on Windows, macOS, and Linux.
- Monitor and remediate sensor health, and continuously reconcile Defender coverage against authoritative inventory so that unmonitored endpoints are found and fixed rather than discovered during an incident.
- Manage antivirus and protection policy - scan behavior, definition currency, at tack surface reduction rules, exclusions, and platform-specific configuration - balancing security outcome against engineering workload impact.
- Write and maintain advanced hunting queries to answer posture and exposure questions, and understand the limits of what endpoint telemetry can and cannot show.
- Operate diagnostic tooling (client analyzers and equivalent) and drive vendor cases to resolution when platform defects affect the fleet.
- Act on security recommendations and vulnerability findings surfaced by the platform, prioritizing by real exposure rather than raw score.

Tanium
- Own the architecture, configuration, and operation of the enterprise endpoint management and security platform, including content, permissions, and shared services.
- Author and maintain platform content - sensors, packages, and saved questions - that returns correct answers across every supported operating system, including multi-distribution Linux.
- Design and maintain the role-based access model: roles, personas, user groups, computer groups, and filter groups, scoped to least privilege across multiple consuming organizations.
- Configure action groups and targeting tiers so that change lands predictably and progressively across the fleet.
- Use the platform as the fleet's measurement and remediation instrument: build the content that reports security posture and closes the gap between "we have a policy" and "we can prove it is applied."

Posture reporting, requirements, and documentation
- Instrument the fleet to report security posture against recognized benchmarks (CIS, DISA STIG) and to evidence control implementation for compliance obligations, including NIST 800-series and ISO 27000-series requirements.
- Report on the state of adjacent security controls owned by partner engineers - including disk encryption and device control - using Defender and Tanium telemetry, so that coverage gaps are visible without duplicating ownership of those platforms.
- Build platform content and collectors that triage endpoint and application performance problems - crashes, driver faults, and degradation - and attribute them to a responsible component, so that fleet-wide issues are diagnosed from evidence rather than anecdote.
- Work with engineering and development groups to provide endpoint security requirements for new applications and systems.
- Document processes and procedures relating to endpoint security technologies, at a standard others can execute from.
- Contribute to the endpoint security roadmap and to best practices at the department level.

Technical leadership
- Contribute to the strategy of endpoint security within the team; independently determine and develop technical plans for complex problems and use technical judgement to select methods and techniques best suited to the problem.
- As a senior member of the team, mentor other team members on security technologies and standards.
- Review the work of other team members and be accountable for technical analysis within your discipline.
- Interface effectively with all levels of the organization, up to and including executive staff, as well as external customers and vendors.
- Work closely with the Cyber Security Threat Operations team and partner IT teams to build and maintain endpoint security technologies.
- Regular participation in on-call rotation.
- Available to support flexible work hours to support various organizational objectives.

Qualifications

- Minimum of a bachelor's degree in Information Systems, Computer Science, or equivalent practical experience.
- 5+ years performing deployments and managing endpoint security tooling.
- Hands-on engineering experience operating an enterprise antivirus and endpoint detection and response stack at fleet scale. Microsoft Defender for Endpoint strongly preferred, including onboarding, antivirus and ASR policy configuration, sensor health management, and advanced hunting.
- Hands-on administration and engineering experience with an enterprise endpoint management platform. Tanium strongly preferred.
- Familiarity with endpoint encryption, and with application performance monitoring and troubleshooting.
- Genuine multi-platform depth. Demonstrated ability to administer, instrument, and troubleshoot security tooling on Windows, macOS, and Linux - not deep expertise in one with passing familiarity with the others. Candidates should be able to speak to endpoint security work they have personally done on all three.
- Demonstrated experience executing a platform migration or major version cutover: planning, phased execution, validation, and operational handoff.
- Strong scripting and automation skills across platforms - PowerShell, Python, and/or Bash - to optimize for consistency and efficiency.
- Familiarity with host, network, and cloud-based security technologies.
- Experience with NIST 800-series standards, including 800-30, 800-53, 800-82, and 800-171.
- Experience with ISO 27000-series standards.
- Active Directory and Entra ID concepts as they apply to endpoint identity, scoping, and access.
- Ability to interface with all levels of an organization up to the executive staff and external customers.
- Ability to earn trust, maintain positive and professional relationships, and contribute to a culture of inclusion.
- Ability to convey technical information to technical and non-technical users, and to document epics, stories, and tasks in the enterprise ticketing system.

Desired
- Applicable security certifications - CISSP, GIAC certifications, CISM, CISA, or Security+.
- Experience operating security platforms in a FedRAMP, GCC High, or otherwise accredited cloud environment.
- Experience with Microsoft Intune for endpoint security policy delivery.
- Experience authoring Tanium sensors for Linux across multiple distributions, and an understanding of why cross-platform content is harder than it looks.
- Experience with CMMC-driven control implementation and CUI handling requirements.
- Experience with security automation and orchestration, and with platform APIs for programmatic administration.
- Understanding of incident response processes and the role endpoint telemetry plays in them.
- Experience supporting engineering or manufacturing workstation fleets with specialized hardware and software requirements.
- Exposure to infrastructure-as-code and configuration management (Ansible or equivalent).
- Experience mentoring engineers and raising the operational maturity of a platform beyond single-owner dependency.
