Information System Security Engineer

Senior Systems & Security Administrator

The firm

A boutique civil rights and public interest law firm with headquarters in NY. Cloud-first, Microsoft-native, and currently working towards ISO/IEC 27001:2022 certification. Small technology group, no silos, and a culture that people describe as startup-like (entrepreneurial, fast, and unusually flat for a law firm).

The role

This is the generalist seat that most firms split into two and then wonder why neither half works. Roughly 60/40 infrastructure to security, youll own the environment day to day and operate the technical controls behind the firms security programme, and youll do it reporting closely to the CIO.

The technology group has grown off the back of the firms AI implementation, and this role has room to grow with it.

What youll own

• Identity. Microsoft Entra ID at administrator depth — identity lifecycle, conditional access design, MFA and passwordless, privileged access, SSO.
• Microsoft 365 and endpoints. Exchange Online, SharePoint, OneDrive, Teams and Purview; the Windows estate through Intune and Autopatch — compliance policies, configuration profiles, security baselines, app deployment, Cloud PC.
• Network. Firewall policy, VLAN segmentation, wireless and VPN across three offices, plus the cloud-delivered web security platform. Meraki is what runs here; fluency in enterprise networking matters more than the badge.
• Security operations. SentinelOne and Defender, DLP and device controls. Triage and investigate alongside a managed SOC, and escalate under the incident response plan.
• Incident response. A seat on the Security Incident Response Team — containment, eradication, recovery and root cause.
• Vulnerability and patch management to defined remediation timelines, including the annual third-party penetration test and everything that follows it.
• Automation. A meaningful share of this job is building and maintaining automation in PowerShell, Microsoft Graph and platform-native workflows — provisioning and deprovisioning, configuration, reporting, evidence collection. Youll inherit what already runs as well as build what doesnt exist yet.
• AI tooling. Administer and secure the firms approved AI platforms under the same identity, data protection and logging controls as everything else, and help evaluate what comes next and what controls it needs.

Alongside that: change and configuration management, backup and recovery, alternate Technical Recovery Lead for DR, asset and media management, key custody, and supporting the ISO 27001 programme, internal audit and client security assessments with evidence.

Who you are

• 7 to 10 years in systems administration , including three or more at senior level with real ownership of a production environment.
• Youve done both sides. Infrastructure and security, even if security was a phase rather than a title. This is the rare part, and its the whole point of the role.
• Youve worked inside a governed programme — ISO 27001, SOC 2, NIST CSF, HIPAA, CMMC or equivalent — and youve personally produced evidence for an audit or a client security assessment.
• You script. PowerShell and Graph, or close equivalent.
• Youve worked somewhere small enough to matter. Youd rather own the environment than own a ticket queue, and youre comfortable when the days priorities shift.
